I was wondering if I built the engine, what's the max horsepower that can be made from a stillen supercharger?
The car is a G37x sedan.

 

Search some threads around here. There's tons of them with numbers and dyno sheets.

I believe the most that can be made would be 440-450 depending on the tune and the car. A few have pushed past that but that ends with blown motors and other parts.
