Finally got to the DYNO

Well after trying to get everything ready for the past 5 months I get to the dyno .The first base line run showed 429 rwhp with minor tuning issues then after some adjustments the seconf run showed 447 rwhp.Did some more fine tuning and the 3rd run the assy belt came off for some reason and tuner said the graph showed the belt was starting to slip around 6-8 lbs.So back to the drawing board to figure out whats up with the assy belt.

I was hoping to see 500 but maybe next time I get back with all problems fixed.

Whats your set up, 6 rib, 8 rib, Stock j bracket, SDCE, Aster ???

I would also recommend getting one of these... http://www.qualitytoolsforless.com/P...FQE6QgodrH0AKg

I found my blower pulley was off 1/2 a rib and had to get a .050" shim from fastenal. I have never had the belt come off on me, so yours might be off quite a bit.

You might want to throw on a new belt, once they slip its easier for them to do it again. I would also check the tension of the belt after a short drive and tighten it up again.

Hopefully the katech tensioner solves the serpentine belt problem.
