thats a good writeup and all, but doesnt really answer my question. it basically gives you info on what to do to run like a 3.4 pulley and lower. doesnt really specify hp#'s at all even. i mean a 3.4 pullied and modded car is what...20hp over stock, 50hp? 75? i would have no idea after reading that thread. it actually states how to safely mod your 3800 car to 12's or faster. does doing a 3.4 pulley put these cars into the 12's? a 3.2 pulley? do i need a cam, rockers and intercooler to hit 12's? ive searched this forum a good bit, no havent been all threw it but i havent seen how what im asking has been beaten to death. now if there was a sticky somewhere saying a 3.4 pullied car = "x" hp, 3.2 = "x" hp 3.1 = "x" hp then i could understand but... and thanks to those who have actually tried to answer my question![]()
