I am currently running the following mods on a 99 GTP: zzp pcm, 3" dp w/hi flow converter, 180 stat, al 104s, fenderwell intake and a 3.4" sc pulley... do you think i can try to run a 3.25" pulley or do i need more mods? I am also thinking about doing a E85 conversion as well as that should help too with 105 octane and the cooling of alcohol...

thanks for your help

Re: 3.25 pulley

are you knocking now with your 3.4?

running e85 you should be able to run a 3.25.
