40th Stillen Supercharger Build

Nism0 · 06-20-2014, 03:45 PM

Just recently got my car back. I bought this supercharger kit used, so naturally we were missing some minor parts. The cog belts were the wrong size (tooth count indicated they are actually for a 350z, so they will be for sale soon!), the aftermarket coolant reservoir was too big, few bolts here and there...

After it was all installed we were able to make 400rwhp/340ftlb of torque @ 7psi.

The install/tuning was done by R/T tuning. They did an amazing job -very clean install.

We are currently working out an issue where the ecu switches into valet mode while I'm driving.

Other than that it's very fun to drive and I will post pics soon!

Also wondering if it would be worth getting the 9lb pulleys. I see some people on this forum making high 400's which is where I REALLY would like to be. Are the 9lb pulleys the solution?

Current Setup:
Stillen Supercharger Kit
928 impeller
550cc injectors
Berk Test Pipes
CNT Cat Back Exhaust
Aeromotive Stealth 355lph Fuel Pump
