Severe belt slip on Vortech
I tried getting a final tune on my vortech on Friday, but had an unresolvable problem with belt slip above 5K RPM. The belt was tightened twice during the session. I am running the 3.12 pulley. I have not heard of this problem in an 8psi application. What could be wrong, and what are my options?

You shouldnt have ANY PROBLEMS if you tighten it enough . It has to be much tighter than you think
|
Wish you guys would all just cave and do the TIMROD belt mod, it fixed everything for me.

Hay Vash350,
did you go for the 3.12 or 2.87 pulley? Hows your A/R now? Glad to see someone that someone has some "balls" and tried my belt/pulley redsign. |

Im actually still running the junky 3.33, but i could not get my belt to stop slipping regardless of how tight my belt was. I havent had an issue since i switched to your setup. My A/F's are a little better, but I just ordered a spacer so i am gonna wait until i get that on before i get it perfect. |
Well, my belt was slipping even worse, so I tried to tighten it today. The tensioner was maxed! It wouldn't go any tighter. Could the installers have put on the belt for the stock pully instead of the one for the 3.12? Or is the stock belt so much bigger that it wouldn't work at all if someone tried to use it on the 3.12 pully?
Alan (hoping a simple belt change will solve this problem and I can finally boost!) |
The problem with the stock setup is that the belt has to be extra long just to get it over the pulleys. By the time you take up the slack in the belt and adjust it a few times, theres no more adjustment left and you can't use a shorter belt, because you can't get it over the pulleys. Its a bad design, Do the Fix.............

Timrod.... Are you running that 2.87 w/ 12 PSI on your stock internals?
|
Yes 12psi+ over 30,000 miles no problems

Btw, when you are tightening the bolt, you loosen the tensioner pulley before, right? If not, you need to. |
