3.25 pulley/E85

[mark1970]

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

are you knocking now with your 3.4?

running e85 you should be able to run a 3.25.
