Just talked to the tuner a little while ago he says that it now appears that the belt is slipping.
Appears my 8 rib aint good enough.
Gonna check with Forcefed and ASP to see if I can get a cogged belt.
Does anyone here actually have a cogged setup?
From one of these or some other place?
He hadnt tried a run with the intake ducting off yet I'm expecting some restiction there actually,

 

Many people are running 9's and making 700+ rwhp with the 8 rib set-up. Maybe you have too long of a belt and the tensioner isn't putting enough force on it.

Not sure if there is belt slip after all he did a run today without the inlet in place and got 8 to 10lbs boost.
Still Ive got a call in to Forcefed about a cogged belt.
