[QUOTE=GM Power4Life;4815401]well for the first pulley it would be as much or a lil more as a OD crank pulley. but after its all set up and all they have to do is load the machine the price would be alot less. what did whipple want for them ? like $75...? i know they wont be that cheap but i still think it will be the way to go. and as far as a couple of sizes, each one would have the setup cost also. i would really like to find one or two that people would buy the most. maybe ill know something by this weekend and ill get back to you.

Make a thread about it in forced induction! I'm sure guys will jump all over it. I'd like to have a 3.5". I'm running a 4" now and it's only at 6psi because my 370 breathes a lot. According to Whipple each 1/8" smaller is 1 psi boost increase, Just FYI. Let me know what happens.

 

Send a PM to 907infamous. I think he recently bought a smaller pulley for his Whipple, but I don't know where he got it.
