I was wondering if anyone knew what the maximum amount of boost you could get out of a s/c when you change out the pulleys?

Has anyone done this? If so, then with what size pulley? How much boost and est. power that added (not counting tuning etc)

approx. 80-90whp is DEFINITELY not enough for me, but I like the idea of a more reliable setup with less headaches and such. Before anyone says it, i know i know, turbo sounds like a better route for higher horsepower, but I don't need a extreme amount.

Realistically i'm looking around 350whp to maybe 400whp. Does anyone know if they make a pulley that could deliver that (and yes of course a GOOD TUNE is key to this whole idea and will help make power along with other obvious additions)

Thanks guys!!

Sideways is putting down the most whp on a S/C setup, but if you only want 350-400whp it's easy.just get a 10psi pulley and you're done.

check out this thread you'll find a bunch o stuff on the site about pulley size vs power..

 

THANKS!!!! That really helped out!!

ive seen 15psi on sc s2k before. i think it put out around 450rwhp. you ahve to upgrade the hg for this though

 

Real boost and not what some gauge says is limited with the current centrifical superchargers marketed for the S2000 to around 17 or 18 lbs. My gauge is over 20% optimistic. These high psi numbers are generally very inefficient compression, high temperature and very difficult to reach. Most don't see beyond 14 psi.
I made the same power at 14, 15, and 16 psi.

Take this in the context of less efficient engines will show more boost.

 

perhaps I'm being sarcastic BUT! You cannot have that much of power increase without headache!!!

 

400-550rwhp is considered safe boost for both turbo and sc with everything stock except thicker hg

dont you need to upgrade your injectors and get an ems??
