SOS only recommends the 4.2" pulley for 1200. Unless you are in Denver or something I think the 3.8" is as far as you want to go. The 3.8 with the 1200 is close to pushing 400HP. But I am not the expert here.

Yeah, I'm thinking 3.8 is the way to go. Thanks for the reply.

Ps. Anyone have any luck with strut bars and the supercharger working together?

soulicious

Why you going with 4.56 gears?

s2kslav

soulicious, already have them installed.

I just got my car dialed: 382whp, 242Tq, 11.75# boost at 8500
SOS stage 2, 1200, 4.0", Sideways intake Cam adjust -2˚,upgraded H.E.
T1R dual exhaust

if you are in a state where 93oct is readily available or you are running E85 you might have probs with 3.8"

s2kslav

im in NY, pretty sure 93 is pretty easy to come by, im guessing ill be making around similar numbers as you.

DaGou

soulicious what pulley are you running to get 492HP?

soulicious

3" Reichard Racing, but those numbers should be higher after I go back to the dyno in the next month after some recent changes.

How does she pull? Still have my 4" pulley sitting in my garage while my car got retuned for better midrange response and more power on the stock 4.25".

does anyone have oil pressure readings? wot, idle,ect should the oil pressure be less than stock because of the line to the blower?
