Hey guys, I'm new to the forum and have a question. I picked up a vortechv2 off of a Fox body really cheap. I'm working on fanning up some brackets and what not. I plan on running it on my current serpentine system if possible. My question is since I will be using my current crankshaft pulley, what size blower pulley would you guys reccomend to achieve 12lbs of boost or so. 799 Un ported heads, edelbrock pro flo xt intake. I haven't picked out a camshaft yet. It will have a air to water intercooler. Any other info you need just ask.
Thanks guys
