More boost Stillen SuperCharger kit

Pro4Jackster

That is pretty close to what JTran did with my kit. Upped the S/C rpms with a 34T-30T cog setup on the backside of the blower. I don't remember the exact numbers, but it was spinning the blower around 56,000 rpms. I saw 13 psi regularly and the car held up fine. Next, I swapped to the SI impeller like AMNVQ did and saw around 15-16 psi. That ended the stock motor. We rebuilt and went with a Single Turbo instead of modding the Stillen kit any further.

-It's a good idea to swap back to the stock IM and MAF placement. Build your charge pipes large enough ID to keep your stock MAFs from maxing out (you are going to have to flow a lot more air than the turbo guys to make the same power due to parasitic losses).
-Find a good way to brace the Stillen S/C bracket (it will flex at those power levels and cause belt slip).
-ATI makes an oversized-dampened crank-pulley for our cars that would be perfect for increasing S/C rpms, but it's really expensive (6.5" OD if I remember).
-Check out VSRs intercooler/charge-pipe setup on their Single Turbo, a mirror image of their setup should work good with the Stillen S/C. Single in/Dual out with the inlet on the top-passenger side.
-Talk to Phunk about what your fuel needs will be for 550 whp on a S/C VHR.

I hope some of that helps. Good luck man.
