DO88

Inlet hose kit, 66mm Airbox.

The world´s first model adapted inlet hoses for the Porsche 992



To Fit:
Porsche 911 (992) Turbo 2020 onwards

The inlet system on the Porsche 992 is completely revised from previous versions. It has a completely different layout but the principle is the same of course. As ever – as cold air and as much of it as possible is what brings effect and elevates the driving experience behind the wheel.

Key figures:

• More air to your engine, less back pressure and better airflow! Airflow at 0,175 bar / 2,54 psi pressure drop: 775 CFM (667 CFM), 16 % higher! See diagram.
• 3D, freeform designed inlet hoses made from the finest silicone.
• CNC-machined turbo inlet adapters.
• Fits towards OE or do88 air filter box (66 mm).

Considerations

The efficiency of a turbocharged engine is under direct influence of the inlet air temperature (IAT) and the back pressure in the system. A crucial aspect, yet very often overlooked, is having sufficient airflow before the compressor to avoid surge. Less vacuum and colder air enables the turbo to produce a larger mass which in the end means more air to the intake – summing up, this means noticeable power gains. There are great power wins to be earned with a good induction system! Throughout our years in this business, with countless hours of evaluation and development, we have seen the coherent connection in between IAT, sufficient airflow to the compressor, and the impact this has on the output. The Porsche 911, with its twin turbochargers and vast tuning potential, is always begging for more air!. That was always the case with the 911 – it still is!

DO88 turbo inlet hoses

We started the development by 3D-scanning the entire designated area on the car. This allowed us to work in a sensible manner, with the products in our CAD-environment using SolidWorks. The entire air filter system is optimised for airflow and radiuses and angles are reworked many times to achieve the best result! The finished product is verified with both Computer Flow Dynamics (CFD) as well with our Superflow SF1020 flowbench. All efforts are made to offer real and trustworthy data for you as a customer.

The kit comes with hoses in a textured black finish, CNC-machined adapters towards the turbos and top-quality, black hose clamps. The hoses are adapted to the OE air filter boxes, or the do88 air filter system with 66 mm connections.

Please note that these hoses provide a good upgrade. We consider them a solid first step in the refinement of your Porsche 911. However, we´d like to underline the fact that the best effect is achieved when these hoses are used in junction with the do88 air filter system. With that upgrade, all restrictions before the turbo inlet are eliminated and the turbos can reach their full potential!

If you ask us, this is as good as you can make an intercooler kit for this platform.
No rock has been left unturned in our quest for maximum performance in any given section of the system. The starting point is the cores from renowned Garrett Motorsport, these are incredibly well-made with thin and stacked fins, exactly according to our specification in the weighing of cooling and airflow. The end tanks are made from thin, cast aluminium to keep the weight down and still utilise airflow. To accommodate the thicker core, we replace the air guides with carbon ducts made of the best quality.
To remove bottlenecks throughout the system, the intercooler connections are made bigger and come along with do88 silicone hoses designed with soft, sweeping bends. We have not made any sacrifice or compromise during this development

Key figures:

• Colder inlet air temperature in the same conditions: DO88 30°C / 86 F (OEM 39°C / 102,2 F). DO88 9°C / (16,2 F) lower. See diagram below.
• More air to your engine, less back pressure and better airflow! Airflow at 0,175 bar / 2,54 psi pressure drop: DO88 919 CFM (OEM 820 CFM), DO88 unit 12% higher! See diagram.
• High-density, motorsport-grade Bar&Plate cores from Garrett.
• 3D, freeform-designed cast end tanks.
• Custom designed carbon fibre ambient air guides.
• Comes with high quality silicone hoses and accessories for installation.
• Meth bungs on the intercooler outlet tank (2x 1/8 NPT).

Background:

Upon launching the 992 generation, Porsche had already abandoned the naturally aspirated engine. From now on, all 911´s are turbocharged which makes this entry-level legend interesting also for the ones aiming for those bigger HP-numbers. Each car model comes with its own challenges and preconditions. While the principle is the same as ever, the layout of the intercooler system is something entirely new on this platform compared to previous Porsche 911´s. With our knowledge and experience from previous developments, we sat down by the drawing board with equal shares of confidence and respect. As a pioneer on this new platform on the market we realised we had to be very accurate and forward-thinking. Today we are proud of our achievements for the 992!

Earlier versions of the Porsche 911 have their intercoolers inside each rear fender, with a y-pipe uniting them both before the charge air reaches the inlet manifold. The 992 has a different set-up entirely. The intercooler and y-pipe are now combined to a unit that sits beneath the rear wing. The ambient air is pushed via channels from the rear window, into a scoop on the decklid, and onwards through the intercooler core for optimal heat transfer. The active rear wing is crucial for the efficiency of the core as it directs more air in its upright position. Looking at the construction from the side, this configuration really makes more sense, but is also more demanding for us a performance cooling manufacturer. To be able to fit a core with greater volume and surface area, we had to develop new carbon ducts to allow the increase in thickness. We are very happy to have taken our carbon production to the next level with this product - the fitment and finish worthy of an icon as the 911!

Cores from Garrett:

The cores are Bar&Plate, made by renowned Garrett Motorsport. Quite frankly, they are as good as they get. Thin and stacked cooling fins give a dense construction, providing very efficient heat transfer. The core measures 105 mm (4") and are exactly as thick as you possibly can make them for this application. The air is distributed to the entire core via free form-designed, cast end tanks. Designing these was a significant undertaking that concluded 3D-scanning, CFD-analysis and 3D-printing many times over until we had a finished prototype. We chose, as usual, to use cast end tanks as they allow shapes that CNC-machining cannot replicate, and to us function always conquers form. Maximum airflow supersedes the bling factor! The tanks are made with machined 70 mm (2,75") connections to enable high outputs. To pair with these bigger connections, we also include silicone hoses. Both cores are united by a central outlet tank towards the inlet manifold, utilising machined connections and meth bungs.

Ambient air guides made from carbon:

The air guides are made from vacuum infused, prepreg carbon and all pieces come with fastening grooves for the air channels just like the OE bits. As complex as the shapes are, we still guarantee perfect fitment. The two upper air guides are always the same regardless of what car you have, but for the two lower pieces there is an option: Standard or SportDesign.
SportDesign has better evacuation of the cooling air via an outlet in the middle of the bumper. From a performance standpoint, SportDesign is preferred, but we offer carbon ducts for both versions. They come with proper rubber seals where this is needed to prevent the cooling air to escape pass the core.

Performance:

When it comes down to performance, the do88 intercoolers significantly reduce the intake temperature! In the graph below the difference towards the OE 992 units is presented. The data is collected with an AIM race logger under 5 consecutive runs in an immediate sequence on a closed airstrip. Full throttle accelerations between 50-250 km/h (30-155 mph) carried out in a Porsche 911 Carrera S (450 hp). Hard braking, no cool down in between, just full pull five times. The rear wing was in its upper position all the time.

The test was conducted in the following manner:

Firstly, 5 runs were made with the car equipped with the 992 OE intercoolers. Stop, fast change of parts to the do88 intercoolers. Shakedown for a few minutes and then five runs made in the exact same way as with the OE parts. The decrease in inlet air temperature is significant, peak delta is 9°C (16,2 F). See the graph below!

Cooling is important, and so is airflow. After many hours in the development, refining the end tanks and choosing a core to meet our demand, the result is an intercooler that is much more efficient in terms of heat transfer as well as airflow. Using our in-house flowbench, the Superflow SF-1020 Probench, the airflow is verified for both the do88 intercoolers and the OE 992 units. What you see is what you get – true performance

About the Performace Plenum:

This plenum is designed with soft, sweeping lines with the radius's and angles revised and reworked many times over.
The connections are CNC-machined and the plenum comes with suiting silicone hoses for optimum fitment and durability. The improvement in airflow is verified using CFD (Computer Flow Dynamics) as well as in our Superflow SF1020 flow bench.

Taking away restrictions for the turbocharged air that reaches the inlet will provide better throttle response and performance gains all over the powerband

Key figures

• More air to your engine, less back pressure and better airflow! Airflow at 0,1 bar / 1,45 psi pressure drop: 846 CFM (808 CFM), 5% higher! See diagram!.
• Freeform designed, aluminium casting with CNC-machined connections.
• Y-design for optimum air distribution.
• Comes with all accessories needed for installation.

Background

Upon launching the 992 generation, Porsche had abandoned the naturally aspirated engine for the Carrera models. From now on, all 911´s are turbocharged! There are a few differences in between the Carrera and the Turbo models, the displacement being the most obvious, but they also share a lot of components – the plenum is one of these! Throughout the entire development of the 992 products, we had unlimited in-house access to a 992. This way of procedure is how we always do it. It allows us to test our theories, prototypes and 3D-prints without hurdles or delays. We´d like to think that this shows on the finished product – ultimately refined without compromise. We are confident with what we have to offer the market!

Development

With the starting point in a comprehensive 3D-scan of the engine bay to get the structural limitations, we set to work. With the experience we had from previous Porsche plenums, we soon realised the need for a y-joint rather than the t-shaped OE plenum. From an airflow perspective the y-shape is more efficient as it distributes the air more evenly and with less pressure drop. We chose, as usual, to manufacture the plenum from cast aluminium as it allows for shapes that CNC-machining cannot replicate, and to us function always conquers form. Maximum airflow supersedes the bling factor

Upon launching the 992 generation, Porsche had already abandoned the naturally aspirated engine. From now on, all 911´s are turbocharged which makes this entry-level legend interesting also for those aiming for higher HP-numbers. Each car model comes with its own challenges and preconditions. While the principle is the same as ever, the layout of the intercooler system is something entirely new on this platform compared to previous versions, and this also affects the air intake. Contrary to earlier versions, the 992 no longer has a common, united air filter for both turbo chargers. The air intake is still located in the decklid, now shared with the intercooler ambient duct, but the air filters themselves and their housings are located inside each rear fender, thus better shielded from the surrounding heat from the engine bay. Looking at it from the side, this solution has more thought to it, but there absolutely is room for improvement – we give you the do88 intake kit

Key figures

• More air to your engine, less back pressure and better airflow! Airflow at 0,175 bar / 2,54 psi pressure drop: 1360-1554 CFM (1202 CFM), 13-29 % higher (depending on version) See diagram
• 3D-freeform designed air filter box made in CAD environment
• Vacuum infused, prepreg carbon for best finish and fitment
• Comes with high quality silicone hoses and accessories
• Fits towards OE or do88 inlet hoses (66 mm or 80 mm connection)
•Washable BMC cone filters with improved airflow. We recommend following the BMC regeneration procedure every 20,000 – 25,000 kms. See separate item

About the Induction System:

We started the development by 3D-scanning the entire designated area on the car. This allowed us to work in a sensible manner, with the products in our CAD-environment using SolidWorks. The entire air filter system is optimised for airflow and radius's and angles are reworked many times to achieve the best result! The finished product is verified with both Computer Flow Dynamics (CFD) as well with our Superflow SF1020 flowbench. All efforts are made to offer real and trustworthy data for you as a customer.

The do88 air intake kit is made from vacuum infused, prepreg carbon fibre of the finest quality. It comes with CNC-machined connections towards the turbo inlet hoses. To boost the airflow, the kit really takes advantage of the full space provided within the car´s structure. The carbon housings are made to accommodate a big, inverted cone filter from renowned BMC, featuring their finest filter media at hand. The intake kit is held in place by a stainless water jet cut bracket. The do88 intake kit replaces the entire OE air filter box and is a true performance upgrade!

Included in this kit are also custom silicone hoses made to ensure a perfect fitment towards the car´s air guides, shared with the intercoolers. This makes for a completely closed joint where no air can escape. The hoses come in a discrete, matte black finish.

This kit contains all you need to mount this on a Carrera, Carrera S or a GTS. It comes in three different versions:

• do88 intake kit alone with 66mm connections towards OE inlet hoses.
• do88 intake kit with 66mm connections and do88 66mm inlet hoses.
• do88 intake system with 80mm connections and 80mm inlet hoses.

All three options provide better airflow, see the diagram for data. The model with 80mm connections will steal more room on the inner fender, by the rear tires. Please consider this when/if further modifications are done on the vehicle.

We are very proud of the performance upgrade this kit brings – especially on tuned cars demanding more oxygen, but an otherwise strictly unmodified car will also see improvements from the better airflow

Significant advantages with Do88's high flowing turbo inlet pipes:

• More air to your engine, less back pressure and better airflow
• Mandrel bent aluminium piping in black powder coating
• Special design, high-temp spec. hoses in a matte black finish
• Top-quality, constant tension hose clamps
• Comes with all accessories for installation

About the Intercooler Pipes:

Crafted from mandrel bent 63 mm (2,5") aluminium piping, this kit offers improved airflow and more resilience over time. They are wrapped up in a matte black, structure powder coating. As a finishing touch they come with matte black silicone hoses, whereof the turbo outlet hoses are made from a high-temp spec. material that can handle 240°C continuous temperature. The hose clamps for this position are of the "constant tension" type, meaning they will compensate for temperature fluctuations in the material.

The use of 3D scanning to generate a 3D model in our CAD environment really opens up the possibilities to optimise the products as much as possible. With the car´s given structure as a base, we reworked the piping and hoses for radius's and angles many times over until there was no more room for improvement. This scientific approach and the flexibility the 3D scanning bring to our developments is unprecedented - we can verify airflow and performance instantly

The result is a product that flows better than the OE pipework, improves the looks and will outlast the flimsy OE hoses over time

About the Intercoolers:

Do88: After our market research in the beginning of our intercooler development for the 997 generation 2 we understood that not many of the upgrade products on the market are really upgrades but more at the same level as the 997.2 standard intercoolers or sometimes even lower. For this reason we realised from the beginning we could not sacrifice anything to keep the cost down, we just had to do the best possible in the space available in the car!

First of all we carried out a lot of investigation and comparisons between different core types and at last really fell for a high density motorsport core which has great cooling efficiency as well as being light weight. With a great core in place we started to refine the end tank design which brought us to a decision to make cast end tanks as we could then control the air flow distribution over the core in a very precise way. This is very important as a good tank design will be beneficial for both pressure drop and cooling efficiency.

To be able to fit an intercooler with appropriate thickness for the job it was also necessary to design a new upper ambient air guide. This was designed in our 3D scanned environment from carbon fibre to ensure perfect fit to the vehicle integrated air guides and our intercooler. To achieve the best air flow distribution over the core we made intercooler end tanks with 70 mm (2 3/4 inch) connections which then made it necessary to designed custom silicone hoses for all positions.

The hoses are 3D designed with airflow in mind where we CFD tested each hose during development to ensure best possible flow rate of all parts! The hoses between turbocharger and intercooler are special silicone hoses that can withstand up to 240°C (464°F) continuous temperature! Another important aspect for cooling performance is to maximise all ambient cooling air available, to optimize this part we include air block rubber seals for all surfaces where the ambient air guides must seal properly.

With the way we have chosen to build our intercoolers the weight increase compared to the OEM ones is relatively small considering the size of our intercooler and that it's completely made of aluminium. Our intercooler weight is 5,85 kg (12,89 lb) per piece and the 997.2 OEM intercooler weights 3,30 kg (7,27 lb) per piece. It might sound like a big weight increase but not when you compare it to similar core sized intercoolers on the market!

About the Y-Pipe:

Do88: At the beginning of the development process of this product we spent a lot of time thinking what would be the preferred way to build a Y-pipe and here is the result of our conclusions and development process! Our pipe has both a very good flow rate and a low weight which is achieved by combining mandrel bent lightweight pipes with a high quality 3D freeform designed cast joint between them. Onto the cast part we then welded CNC-machined connections for bov and breather hoses.

This construction adds a lot of performance but only small amount of extra weight. Do88 Performance Y-pipe weight 1,52 kg (3,35 lb) OEM plastic pipe weight 1,38 kg (3,04 lb) and competitor cast performance pipe weight 2,76kg (6,08 lb)!

The pipes are then finished in a high quality powder coat that makes them look as good as they perform! You can choose between the more discrete semi gloss black and a fresh silver metallic finish.

About the Inlet Pipes:

Do88: It was a real challenge developing new turbo intake hoses for the 997.2 Turbo. The lack of space makes it really difficult to make a set of hoses that outflow the stock OEM plastic pipes. We achieved this and succeeded in maximising the performance but we had to make the small compromise of letting the hoses have no clearance; so they will push or rub in some non-sensitive areas. The hoses are reinforced with stainless steel wire to ensure overall durability and lasting performance.

Our self-developed intake hoses increase air flow; 26% higher than the OEM hoses. We can ensure you the sensation while driving is very different. The improvement in throttle response is immense, making the car feel so much more refined and alert. This upgrade makes it become what it should have been from the start. This is an improvement no test figures can explain, it has to be perceived behind the wheel of a 997 turbo!

Overall Performance:

Do88: When it comes to performance our big pack gives a great reduction of the intake temperature compared to the OEM 997.2 intercoolers and Y-pipe! See enlarged diagrams where we show data from our AIM racelogger recorded at 5 full throttle accelerations done in an immediate sequence without any cool down between 40-260 km/h (25-162 mph) in a Stage 1 tuned Porsche 997.2 Turbo PDK. In all tests the car was driven in Sport Plus, automatic gear change and AC off. First we made 5 runs with the car equipped with OEM intercooler and y-pipe then we switched to do88 performance intercoolers and y-pipe and drove car for a while, then we made 5 runs exactly the same as with the OEM parts. The temperatures are significant lower with our intercoolers which is visible in the graph!

As well as lower intake temperature our big pack also flows better than the 997.2 original intercoolers! See enlarged image showing the air flow rates at different pressure drops in the graph where we compared our big pack to the original intercooler and Y-pipe in our own Superflow SF-1020 Probench to verify the final result!

From our five in a row full throttle accelerations between 40-260 km/h (25-162 mph) we have very accurate and consistent test data for the range 50-250 km/h (31-155 mph). When analyzing the numbers, we found that in average we cut down the acceleration time for 50-250 km/h (31-155 mph) by 3 seconds compared to the OEM intercooler and y-pipe! No software programming or adaption reset was done in between the tests.

About the intercoolers:

Do88: After our market research in the beginning of our intercooler development for the 997 generation 2 we understood that not many of the upgrade products on the market are really upgrades but more at the same level as the 997.2 standard intercoolers or sometimes even lower. For this reason we realised from the beginning we could not sacrifice anything to keep the cost down, we just had to do the best possible in the space available in the car!

Please have a look at the air flow rates at different pressure drops in the graph below where we compared our intercooler with hoses to the original intercooler with hoses in our own Superflow SF-1020 Probench to verify the final result!

Keep in mind that the OEM intercoolers was designed for only the power level the car was built for originally. A power increase may cause your stock intercoolers to not be efficient enough. So even on an engine with a software tune only or using your car in hot climate the do88 performance intercooler kit will give a performance increase over the OEM intercoolers!

This do88 performance intercooler kit comes as a complete package with all parts necessary for installation.

Installation Instruction

About the Y Pipe

Our pipe has both a very good flow rate and a low weight which is accommodated by composing mandrel bent lightweight pipes with a high quality 3D freeform designed cast joint between them. Onto the cast part we then weld CNC-machined connections for bov and breather hoses. This construction technique adds a lot of performance but only a touch of extra weight. The pipes are then finished in a high quality powder coat that makes them look as good as they perform!

When it comes to air flow performance our Y-pipe totally outperforms the OEM Y-pipe by 58% increased flow at the same pressure drop! Be aware of that the OEM parts are only designed for the power level the car was built for originally. A power increase may cause your stock Y pipe to hold back the power of your engine. So even on an engine with a software tune only the do88 performance Y-pipe will give a performance increase over the OEM Y-pipe!

Much larger inner diameter for improved air flow, 58 % higher! (see graph images).
Made of 2,5" (63mm) mandrel bent aluminium pipes.
The pipe has two methanol injection connections (1/8 -27 NPT). The pipe is delivered with blanking plugs in these connections.
Smooth flow cast collector part.
Smooth internal surface for best air flow.
Comes with high quality silicone hoses and accessories for installation.

About the Inlet Hoses

do88 proudly presents the worlds first high flowing turbo inlet hoses for Porsche 991.1 / 991.2 Turbo. Self developed by do88 in Sweden !

• Much larger overall inner diameter for improved air flow, 31 % higher! (see graph diagram ). The hoses have a 2,5 inch (63mm) inner diameter at the narrowest location.
• Smooth flow transitions.
• Very smooth internal surface for best air flow.
• Excellent thermal properties, the hoses will not absorb heat from the engine.
• The hoses are reinforced with stainless steel wire to eliminate the risk of implosion on high out-takes.

It was a real challenge developing new turbo intake hoses for the 991 Turbo. The lack of space made it really difficult to make a set of hoses that would outflow the stock plastic pipes. We succeeded but in some smaller areas we had to compromise and allow these hoses to have no clearance, so they will push or rub in some non-sensitive areas.

We can ensure you the sensation while driving is very different. The improvement in throttle response is immense, making the car feel so much more refined and alert. This upgrade makes it become what it should have been from the start. This is an improvement no test figures can explain, it has to be perceived behind the wheel of a 991 turbo!

The inlet hose package includes everything for mounting:

• 2 wire-reinforced silicone hoses
• 2 silicone hoses
• 2 breather valves
• 2 CNC machined VTG adapters
• Clamps and Screws

This product is available in 2 options, OEM Porsche turbos or with 51.5mm turbo adapters for cars where the compressor wheel has been replaced, and compressor housing machined larger.

Porsche 991 Turbo and Turbo S 2013-2015

A true performance cooling upgrade for the 991 Turbo / Turbo S

This is the most refined of all products we carry today!

• Significantly improved Air flow! (see graph images).
• Cooler air to your engine!
• High quality high density UK made motorsport cores.
• 3D freeform designed cast end tanks
• Custom designed carbon fiber ambient air guides.
• Comes with high quality silicone hoses and accessories for installation.

About the intercoolers: Right from the beginning we realised that we could not sacrifice anything to keep the cost down we just had to do the best possible in the space available in the car!

First of all we made a lot of investigation and comparisons between different core types and at last really fell for a high density motorsport core which have great cooling efficiency along with a low weight.

With a great core in place we started to refine the end tank design which brought us to a decision to make cast end tanks as we could then control the air flow distribution over the core in a very precise way. This is very important as a good tank design will be beneficial for both pressure drop and cooling efficiency.

To be able to fit an intercooler with appropriate thickness for the job it was also necessary to design a new upper ambient air guide. This was designed in our 3D scanned environment to ensure perfect fit to the vehicle integrated air guides and our intercooler.

To achieve the best air flow distribution over the core we made intercooler end tanks with 70 mm (2 3/4 inch) connections which then made it necessary to design custom silicone hoses for all positions. The hoses are 3D designed with airflow in mind where we CFD tested each hose during development to ensure best possible flow rate of all parts! The hoses between turbocharger and intercooler are special silicone hoses that can withstand up to 240°C (464°F) continuous temperature!

Another important aspect for cooling performance are to use all ambient cooling air available, to optimize this part we include air block rubber seals for all surfaces where the ambient air guides must seal properly.

Using this design in building our intercoolers the weight increase compared to the OEM ones is relatively small considering the size of our intercooler and that its all made of aluminium. Our intercooler weight is 5,4 kg (11,9 lb) per piece and the 991 OEM intercooler weights 3,1 kg (6,8 lb) per piece. It might sound like a big weight increase but compared to other actors on the market with intercoolers in this size it's a low weight!

do88 Performance inlet plenum.



To fit:
Porsche 991 Turbo and Turbo S from 2013 onwards

do88 are proud to present our newly developed Inlet Plenum for the Porsche 991 Turbo and Turbo S

With this high flow Plenum, the performance of your 991 will increase!

• do88 plenum is Y-shaped for improved air flow. • Our plenum flows 5,4% better compared with the OEM plenum (IPD aftermarket 2,1%) (see graph image)
• High quality casting pipe with CNC-machined connections
• Smooth internal surface for best air flow
• Comes with all necessary accessories for installation.

The OEM 991 Turbo plenum is T-shaped which means the air flow from the throttle body abruptly change direction when it´s divided to each side of the intake manifolds. It makes sense to design a plenum with a Y-shape instead of a "bank into the wall" flat T-shape. During the development process of this plenum we spent a lot of time with flow simulations of the internal Y-shape design. We made both flow simulations on our CAD system and real tests on our own SuperFlow SF-1020 flow bench using 3D-printed models.

To be able to manufacture this final design we choose to make a 3D freeform designed casting. This construction adds a lot of performance but not so much of extra weight. We designed the outside of the plenum to add as little weight as possible to the plenum.

do88 Performance Plenum weight 0,66 kg (1,46 lb) OEM plastic pipe weight 0,27 kg (0,60 lb) and competitor cast performance pipe (IPD) weight 1,13kg (2,49 lb)!

Be aware that the OEM parts were designed for the power level the car was built for originally. A power increase may cause your stock plenum to hold back the power of your engine. So even on an engine with a software tune only the do88 performance plenum will give a performance increase!

do88 performance plenum comes as a complete package with all parts necessary for installation.

Extreme high flow performance Y-Pipe.



To Fit:
Porsche 997.2 Turbo models 2010 to 2012

At the beginning of the development process of this product we spent a lot of time thinking what would be the preferred way to build a Y-pipe; here is the result of our conclusions and development process!

Significant advantages with Do88's Y-pipe compared to the OEM pipe:

• Much larger inner diameter for improved air flow, do88 62% higher!
• 70mm mandrel bent aluminium pipes.
• Smooth flow cast collector part.
• Smooth internal surface for best air flow.
• Comes with high quality silicone hoses and accessories for installation.
• See enlarged images for more information!

Our pipe has both a very good flow rate and a low weight which is achieved by combining mandrel bent lightweight pipes with a high quality 3D freeform designed cast joint between them. Onto the cast part we then welded CNC-machined connections for bov and breather hoses.This construction adds a lot of performance but only small amount of extra weight. Do88 Performance Y-pipe weight 1,52 kg (3,35 lb) OEM plastic pipe weight 1,38 kg (3,04 lb) and a competitors cast performance pipe weight 2,76kg (6,08 lb)!

The pipes are then finished in a high quality powder coat that makes them look as good as they perform! You can choose between the more discrete semi gloss black and a fresh silver metallic finish.

The kit also includes 2 high quality custom designed silicone hoses which are available in two different versions. Which version you need depends on if you will install the Y-pipe together with the OEM intercoolers or the do88 performance intercoolers.

When it comes to air flow performance our Y-pipe totally outperforms the OEM Y-pipe by 62% increased flow at the same pressure drop! On our final tests of this Y-pipe together with our intercoolers on a Stage 1 tuned 997.2 Turbo PDK we measured a great performance increase. In all tests the car was driven in Sport Plus, automatic gear change and AC off. From our five in a row full throttle accelerations between 40-270 km/h (25-168 mph) we have very accurate and consistent test data for the range 50-250 km/h (31-155 mph). When analyzing the numbers, we found that we cut down the acceleration time for 50-250 km/h (31-155 mph) by 3 seconds!

Included parts in this kit:

• Full aluminium performance Y-pipe
• Silicone hoses
• Hose clamps
• Hose adaptors if the Y-pipe will be installed together with OEM intercoolers

Complete performance charge air high flow cooling kit with inlet pipes.
Full Big Pack including Inlet Hoses.



To fit:

This complete package includes Do88's motorsport grade intercooler package with carbon fibre air guides, high flow Y-pipe with all hoses and accessories for installation and the optional high flow inlet hoses.

The intercooler and y-pipe are great products individually but as a team they give great reduction of inlet air temperatures and at the same time they reduce the back pressure of the whole system; this means increased power!

Significant advantages with Do88's Porsche Performance Charge Air High Flow Kit:

• Cooler air to your engine! 38°C (52°C), do88 14°C lower than OEM parts!
• High quality high density UK made motorsport cores
• 3D freeform designed cast end tanks
• Custom designed carbon fibre ambient air guides
• Assembly air flow at 0,175bar/2,54psi pressure drop: 646CFM (564CFM), do88 15% higher!
• Post intercooler air temperature at same conditions: 38°C (52°C), do88 14°C lower!
• Y-pipe made of 70mm mandrel bent aluminium pipes
• Y-pipe smooth flow cast collector part
• Comes with high quality silicone hoses and accessories for installation
• See enlarged images for more information!

About the Intercoolers:

Do88: After our market research in the beginning of our intercooler development for the 997 generation 2 we understood that not many of the upgrade products on the market are really upgrades but more at the same level as the 997.2 standard intercoolers or sometimes even lower. For this reason we realised from the beginning we could not sacrifice anything to keep the cost down, we just had to do the best possible in the space available in the car!

First of all we carried out a lot of investigation and comparisons between different core types and at last really fell for a high density motorsport core which has great cooling efficiency as well as being light weight. With a great core in place we started to refine the end tank design which brought us to a decision to make cast end tanks as we could then control the air flow distribution over the core in a very precise way. This is very important as a good tank design will be beneficial for both pressure drop and cooling efficiency.

To be able to fit an intercooler with appropriate thickness for the job it was also necessary to design a new upper ambient air guide. This was designed in our 3D scanned environment from carbon fibre to ensure perfect fit to the vehicle integrated air guides and our intercooler. To achieve the best air flow distribution over the core we made intercooler end tanks with 70 mm (2 3/4 inch) connections which then made it necessary to designed custom silicone hoses for all positions.

The hoses are 3D designed with airflow in mind where we CFD tested each hose during development to ensure best possible flow rate of all parts! The hoses between turbocharger and intercooler are special silicone hoses that can withstand up to 240°C (464°F) continuous temperature! Another important aspect for cooling performance is to maximise all ambient cooling air available, to optimize this part we include air block rubber seals for all surfaces where the ambient air guides must seal properly.

With the way we have chosen to build our intercoolers the weight increase compared to the OEM ones is relatively small considering the size of our intercooler and that it's completely made of aluminium. Our intercooler weight is 5,85 kg (12,89 lb) per piece and the 997.2 OEM intercooler weights 3,30 kg (7,27 lb) per piece. It might sound like a big weight increase but not when you compare it to similar core sized intercoolers on the market!

About the Y-Pipe:

Do88: At the beginning of the development process of this product we spent a lot of time thinking what would be the preferred way to build a Y-pipe and here is the result of our conclusions and development process! Our pipe has both a very good flow rate and a low weight which is achieved by combining mandrel bent lightweight pipes with a high quality 3D freeform designed cast joint between them. Onto the cast part we then welded CNC-machined connections for bov and breather hoses.

This construction adds a lot of performance but only small amount of extra weight. Do88 Performance Y-pipe weight 1,52 kg (3,35 lb) OEM plastic pipe weight 1,38 kg (3,04 lb) and competitor cast performance pipe weight 2,76kg (6,08 lb)!

The pipes are then finished in a high quality powder coat that makes them look as good as they perform! You can choose between the more discrete semi gloss black and a fresh silver metallic finish.

About the Inlet Pipes:

Do88: It was a real challenge developing new turbo intake hoses for the 997.2 Turbo. The lack of space makes it really difficult to make a set of hoses that outflow the stock OEM plastic pipes. We achieved this and succeeded in maximising the performance but we had to make the small compromise of letting the hoses have no clearance; so they will push or rub in some non-sensitive areas. The hoses are reinforced with stainless steel wire to ensure overall durability and lasting performance.

Our self-developed intake hoses increase air flow; 26% higher than the OEM hoses. We can ensure you the sensation while driving is very different. The improvement in throttle response is immense, making the car feel so much more refined and alert. This upgrade makes it become what it should have been from the start. This is an improvement no test figures can explain, it has to be perceived behind the wheel of a 997 turbo!

Overall Performance:

Do88: When it comes to performance our big pack gives a great reduction of the intake temperature compared to the OEM 997.2 intercoolers and Y-pipe! See enlarged diagrams where we show data from our AIM racelogger recorded at 5 full throttle accelerations done in an immediate sequence without any cool down between 40-260 km/h (25-162 mph) in a Stage 1 tuned Porsche 997.2 Turbo PDK. In all tests the car was driven in Sport Plus, automatic gear change and AC off. First we made 5 runs with the car equipped with OEM intercooler and y-pipe then we switched to do88 performance intercoolers and y-pipe and drove car for a while, then we made 5 runs exactly the same as with the OEM parts. The temperatures are significant lower with our intercoolers which is visible in the graph!

As well as lower intake temperature our big pack also flows better than the 997.2 original intercoolers! See enlarged image showing the air flow rates at different pressure drops in the graph where we compared our big pack to the original intercooler and Y-pipe in our own Superflow SF-1020 Probench to verify the final result!

From our five in a row full throttle accelerations between 40-260 km/h (25-162 mph) we have very accurate and consistent test data for the range 50-250 km/h (31-155 mph). When analyzing the numbers, we found that in average we cut down the acceleration time for 50-250 km/h (31-155 mph) by 3 seconds compared to the OEM intercooler and y-pipe! No software programming or adaption reset was done in between the tests.

This was designed in our 3D scanned environment from carbon fibre to ensure perfect fit to the vehicle integrated air guides and our intercooler. To achieve the best air flow distribution over the core we made intercooler end tanks with 70 mm (2 3/4 inch) connections which then made it necessary to designed custom silicone hoses for all positions.

The hoses are 3D designed with airflow in mind where we CFD tested each hose during development to ensure best possible flow rate of all parts! The hoses between turbocharger and intercooler are special silicone hoses that can withstand up to 240°C (464°F) continuous temperature! Another important aspect for cooling performance is to maximise all ambient cooling air available, to optimize this part we include air block rubber seals for all surfaces where the ambient air guides must seal properly.

With the way we have chosen to build our intercoolers the weight increase compared to the OEM ones is relatively small considering the size of our intercooler and that it's completely made of aluminium. Our intercooler weight is 5,85 kg (12,89 lb) per piece and the 997.2 OEM intercooler weights 3,30 kg (7,27 lb) per piece. It might sound like a big weight increase but not when you compare it to similar core sized intercoolers on the market!

About the intercoolers:

Do88: After our market research in the beginning of our intercooler development for the 997 generation 2 we understood that not many of the upgrade products on the market are really upgrades but more at the same level as the 997.2 standard intercoolers or sometimes even lower. For this reason we realised from the beginning we could not sacrifice anything to keep the cost down, we just had to do the best possible in the space available in the car!

First of all we carried out a lot of investigation and comparisons between different core types and at last really fell for a high density motorsport core which has great cooling efficiency as well as being light weight. With a great core in place we started to refine the end tank design which brought us to a decision to make cast end tanks as we could then control the air flow distribution over the core in a very precise way. This is very important as a good tank design will be beneficial for both pressure drop and cooling efficiency.

To be able to fit an intercooler with appropriate thickness for the job it was also necessary to design a new upper ambient air guide. This was designed in our 3D scanned environment from carbon fibre to ensure perfect fit to the vehicle integrated air guides and our intercooler. To achieve the best air flow distribution over the core we made intercooler end tanks with 70 mm (2 3/4 inch) connections which then made it necessary to designed custom silicone hoses for all positions.

The hoses are 3D designed with airflow in mind where we CFD tested each hose during development to ensure best possible flow rate of all parts! The hoses between turbocharger and intercooler are special silicone hoses that can withstand up to 240°C (464°F) continuous temperature! Another important aspect for cooling performance is to maximise all ambient cooling air available, to optimize this part we include air block rubber seals for all surfaces where the ambient air guides must seal properly.

With the way we have chosen to build our intercoolers the weight increase compared to the OEM ones is relatively small considering the size of our intercooler and that it's completely made of aluminium. Our intercooler weight is 5,85 kg (12,89 lb) per piece and the 997.2 OEM intercooler weights 3,30 kg (7,27 lb) per piece. It might sound like a big weight increase but not when you compare it to similar core sized intercoolers on the market!

About the Y-Pipe:

Do88: At the beginning of the development process of this product we spent a lot of time thinking what would be the preferred way to build a Y-pipe and here is the result of our conclusions and development process! Our pipe has both a very good flow rate and a low weight which is achieved by combining mandrel bent lightweight pipes with a high quality 3D freeform designed cast joint between them. Onto the cast part we then welded CNC-machined connections for bov and breather hoses.

This construction adds a lot of performance but only small amount of extra weight. Do88 Performance Y-pipe weight 1,52 kg (3,35 lb) OEM plastic pipe weight 1,38 kg (3,04 lb) and competitor cast performance pipe weight 2,76kg (6,08 lb)!

The pipes are then finished in a high quality powder coat that makes them look as good as they perform! You can choose between the more discrete semi gloss black and a fresh silver metallic finish.

Overall Performance:

When it comes to performance our big pack gives a great reduction of the intake temperature compared to the OEM 997.2 intercoolers and Y-pipe! See enlarged diagrams where we show data from our AIM racelogger recorded at 5 full throttle accelerations done in an immediate sequence without any cool down between 40-260 km/h (25-162 mph) in a Stage 1 tuned Porsche 997.2 Turbo PDK. In all tests the car was driven in Sport Plus, automatic gear change and AC off. First we made 5 runs with the car equipped with OEM intercooler and y-pipe then we switched to do88 performance intercoolers and y-pipe and drove car for a while, then we made 5 runs exactly the same as with the OEM parts. The temperatures are significant lower with our intercoolers which is visible in the graph!

As well as lower intake temperature our big pack also flows better than the 997.2 original intercoolers! See enlarged image showing the air flow rates at different pressure drops in the graph where we compared our big pack to the original intercooler and Y-pipe in our own Superflow SF-1020 Probench to verify the final result!

From our five in a row full throttle accelerations between 40-260 km/h (25-162 mph) we have very accurate and consistent test data for the range 50-250 km/h (31-155 mph). When analyzing the numbers, we found that in average we cut down the acceleration time for 50-250 km/h (31-155 mph) by 3 seconds compared to the OEM intercooler and y-pipe! No software programming or adaption reset was done in between the tests.

High flowing turbo inlet hose kit



To Fits:
Porsche 911 997.2 Turbo 2010 to 2015 with 6-Speed / PDK gearbox.

Significant advantages with Do88's high flowing turbo inlet pipes:

• Much larger overall inner diameter for improved air flow, do88's is 26% higher!
•The hose has 2.5 inch (63mm) internal diameter at the smallest location.
•Smooth flow transitions and very smooth internal surfaces for best possible air flow.
•Excellent thermal properties, the hoses will not absorb heat from the engine.
•The hoses are reinforced with stainless steel wire to eliminate the risk of collapse on high engine output!
•See enlarged images for more information.

About the Inlet Pipes:

Do88: It was a real challenge developing new turbo intake hoses for the 997.2 Turbo. The lack of space makes it really difficult to make a set of hoses that outflow the stock OEM plastic pipes. We achieved this and succeeded in maximising the performance but we had to make the small compromise of letting the hoses have no clearance; so they will push or rub in some non-sensitive areas. The hoses are reinforced with stainless steel wire to ensure overall durability and lasting performance.

Our self-developed intake hoses increase air flow; 26% higher than the OEM hoses. We can ensure you the sensation while driving is very different. The improvement in throttle response is immense, making the car feel so much more refined and alert. This upgrade makes it become what it should have been from the start. This is an improvement no test figures can explain, it has to be perceived behind the wheel of a 997 turbo!

Included in the kit:

• 2 x Wire reinforced silicone hoses
• 2 x CNC machined VTG adaptors
• All hardware for installtion!

Performance inlet plenum.



To Fit:
Porsche 997 Turbo and Turbo S from 2010-2012

do88 are proud to present our newly developed Inlet Plenum for the Porsche 991 Turbo and Turbo S

With this high flow Plenum, the performance of your 991 will increase!

• do88 plenum is Y-shaped for improved air flow. • Our plenum flows 5,4% better compared with the OEM plenum (IPD aftermarket 2,1%) (see graph image)
• High quality casting pipe with CNC-machined connections
• Smooth internal surface for best air flow
• Comes with all necessary accessories for installation.

The OEM 997.2 Turbo plenum is T-shaped which means the air flow from the throttle body abruptly change direction when it´s divided to each side of the intake manifolds. It makes sense to design a plenum with a Y-shape instead of a "bank into the wall" flat T-shape. During the development process of this plenum we spent a lot of time with flow simulations of the internal Y-shape design. We made both flow simulations on our CAD system and real tests on our own SuperFlow SF-1020 flow bench using 3D-printed models.

To be able to manufacture this final design we choose to make a 3D freeform designed casting. This construction adds a lot of performance but not so much of extra weight. We designed the outside of the plenum to add as little weight as possible to the plenum.

do88 Performance Plenum weight 0,66 kg (1,46 lb) OEM plastic pipe weight 0,27 kg (0,60 lb) and competitor cast performance pipe (IPD) weight 1,13kg (2,49 lb)!

Be aware that the OEM parts were designed for the power level the car was built for originally. A power increase may cause your stock plenum to hold back the power of your engine. So even on an engine with a software tune only the do88 performance plenum will give a performance increase!

do88 performance plenum comes as a complete package with all parts necessary for installation.
