We're going to keep it here for now and take the car back to Vortech for a redesign of the pulleys and belts, using thicker and wider belts.
I'll get more pics up soon.
Thanks.

Forget the HP, I'm more concerned about the TQ. I'll be at the Huntington meet, can't wait to see that thing in person. Peace

Man I feel your pain, both Procharger & Vortec suffer from the same issues with high boost applications. Good luck!

KTaylor showed me the thicker and wider kevlar belts. They look like a part off an M1 Tank. KTaylor can probably put you in touch with the supplier, or maybe Vortech has another source for them.

I can,t see why you Vortech Guys don't use My Belt/Pulley redesign. I'm Making 12.5lbs of Boost, Works Fine........ One (1) adjustment in 15,000+ MILES. Never Squeals. Never Boost Loss. Before this I was adjusting the belt every 100 Miles. Not saying this would work for 18+ lbs of Boost, But I think this design with 10 rib pulleys would do the job.

Not saying your idea isnt a good one , or wouldnt help a little . But the belt slipping issue at higher boost levels [ 13psi and above ] is going to happen regaurdless of how you have the pulleys set up . With the stock set up , Im getting belt slippage at 13psi @5900rpm to redline . Before I went to the bigger IC . The belt started slipping at 13psi @ 6300rpm to redline . A serp belt with our kit will not grab after 13psi . The PSI between the blower and IC I would think would be 2 to 5 psi higher .
