Ok guys ive managed to find my self in a good position, i have a 06 ss /sc, stage 2 with a 77.9mm pully, pressing 14.5psi. now from all the knowledge ive learned from all of you im seeing that it is possible to press 17psi, im very intrested in doing so. Few questions, wut would i need to do so, pully size, wut kind of horse power would i be looking at, and if anyone knows the 1/4mi time. as much info on this topic would much loved, help!

 

I and ALOT of memebers on the site will tell u talk to NATE(makes any size pulley u want) and get a 2.9...its the best size for the s2 injectors..u can go 2.85,but ull be maxing the injectors out and it might work,might not...thats a chance u want to take,its up to u...u prolly would be making bout 16.5-17 psi with a 2.9"(im seein 17)and 1/4 mile depends on the driver and track prep and alot of other crap......i managed to pull a 13.6 with just the
s2,but havent gone back to track with the new setup...u prolly would be around 13.6-14.00...power wise...260ish

 

Its really not that safe to be runing a 2.79 on stage 2 injectors, if you want more boost go with a 2,7 and 60s, More boost doesnt always mean more power, your just spining the blower that much faster and creating that much more heat.

 

If you want more HP change this car LOL.
