What kind of boost increase will I see swapping the stock 3.33" blower pulley for a 3.00"? I'm seeing about 5-6 psi at 5800 with the stock stuff.

I'd say 10-12 is a good ballpark.
89 Coupe with parts stacked inside of it and about 30#'s of dust on it with no end in sight. :weird:
Although I am collecting parts for a 12.5:1 393 :D
I saw 13#'s with the 3.00 pulley.
1993 notch, 357W forged pistons 9.2-1 comp,Vortech S-trim 3" / 8" pullies, AFR 185 heads, Trick Flow R intake, Anderson B451 cam, PMAS 80mm, 06 PMS, 60# injectors, 3.55 gears and PA SC C4, Dual Walbro fuel system. Best ET 10.35 @ 135mph
Would you recommend going to something like a 3.15" instead of the 3.00". This is a street car with a stock bottom end. It only has 30K miles but I would like to keep the headgaskets intact. That said, I will be adding a wideband with 42#s and likely a twEECer for fine tuning. Should I go all the way from the stock 3.33" to the 3.00"????
