Lightened crankshaft for steel con rods. 



Fits:
Porsche 911 2.0ltr - 1965 to 1969
Porsche 911 2.2ltr - 1970 to 1971

Notes
Conforms to FIA Appendix K
Tested to 10,000 RPM

Increasing the performance of an engine via the crankshaft does not make sense at first glance, but it is worth taking a closer look. 

The mechanical efficiency of an engine, which, together with the thermodynamic efficiency and the volumetric efficiency, determines the rated output of an engine, depends fundamentally on the diameter of the crankshaft bearings and the friction in the bearings. 

Of course, the diameter cannot be easily changed, but the friction can, which in turn depends on the bending loads and the resulting vibrations of the crankshaft. This is exactly why the use of top-quality titanium connecting rods is of little use if the resulting significantly reduced rotating masses at the connecting rod foot are not also taken into account on the counterweight side of the crankshaft. 

Because only a perfectly designed crankshaft, calculated for the connecting rod weights, actually brings with it less bearing friction due to eliminated vibrations, and thus an increase in performance. Furthermore, this crankshaft is speed-resistant up to 11,000 rpm and tested in continuous operation up to 10,000 rpm. A pleasant side effect is of course a reduced load on the crankcase and less wear. 

This crankshaft is designed utilising the latest calculation methods using CAD and FE methods (finite elements), but is still FIA legal for historic motorsport and conforms to Annex K, but is only designed for operation with steel connecting rods. The focus was on the FIA ​​regulation that " in the case of a new production, the original or the newly manufactured component may be lightened, which was exactly the case with this crankshaft. 

If you want to run this crankshaft with titanium connecting rods, use crankshaft part number 91610201600/1 which is designed for the lower rotating masses of titanium connecting rods. Failure to comply with the mass balance will sooner or later lead to the crankshaft breaking at maximum speeds. 

Furthermore, this crankshaft is an authentic replacement for every standard crankshaft of the 911 from 1965 to 1971, i.e. every 2.0ltr and 2.2ltr engine.

Through bolt o-ring installer for Porsche 911



Installing O-rings on the through bolts for a 911 engine case often slices the rings on the threads of the bolt, leading to ripped seals at best, or a leaky engine at worst. Use this cap to protect the O-ring and to insure a factory quality seal. Precisely machined from quality brass.

Stomski Racing SR024 Through bolt o-ring installer with sleeve for Porsche 911



Based on the factory P9511 tool, STOMSKI RACING's version of this tool incorporates a brass cap and a double-ended stainless steel sleeve to install the o-rings on the crankcase through-bolts of the 3.6 and later cases (but possibly can be used on some other 911 engines). By using the included brass cap to protect the delicate o-ring from getting cut on the threads of the bolt, you then use the "thin" end of the sleeve to slide the o-ring over the brass cap onto the shank of the through-bolt. Once the o-ring is clear of the threads, remove the SR024 brass cap and flip the SR024 stainless steel sleeve over and use the blunted end to securely and gently seat the o-ring in the recess on the 3.6 case.
