nice setup !
how much boost are u running ?

 

After a lot of effort trying to eliminate leaks and belt slipping, we managed to make 9psi at redline.

 

Nice numbers! ^^ try the gtm idler pulley for belt slippage.

 

It's not compatible with the revup kit, and TBH, the revup kit has a similar setup to the GTM mod, so I wouldn't gain anything with it.
Anyway, I'm not slipping anymore, after replacing the Vortech belt with a Gates one.

 

I have found the Bando belt to be exceptional...No belt dust and great gripping power...It came with the GTM pulley mod..

 

Thanks for the tip mate
