I am trying to get my boost to about 16 psi. I am currently running the vortech s/c w/ aftercooler. I lowerd the compression to 10.5:1 with a new set of cp pistons.
payn technologies made a custom pulley that was 4.75" and produced about 10-11psi.
i believe the vortech pulley was 5" and produced about 7 psi.

please help

Where should I go for the pulley and belt? What size do I need?

 

PM Kane.s2k..he can make you a custom pulley to run whatever boost you like.

 

thanks

 

prolly a 4in pulley

 

You'll need a pulley somewhere in the 3.5-3.8" range depending on your rev limit. ASP Racing can machine a nice one for you in any size and in a handful of colors.
