yeah i searched and found about 50 threads on this subject, read through the first page and didnt find the answer i was looking for so here whats going on:
i have a 5% overdrive right now on my bird and see around 12psi of boost at wot. ive also got the stock size jackshaft pulley installed as well. i have a custom exhaust setup thats a 2-1-2 design and is 2.5" all the way with a resonator at the Y and 2 turbo mufflers. i have stock exhaust manifolds right now but i got a pair of ported manifolds with the car when i bought it. my question is would a 10% pulley benefit my any? i think my motor can handle it with the exhaust that i have and if not then i would think that adding on the ported exhaust manifolds would allow me to run the 10% pulley. and since im only seeing 12psi i thought there would be room for a little more boost.
any opinions or comments are great. thanks in advance guys.
