I know you guys were talking about cog belt setups and i found this one off a corvette that i'm going to try probably

 

Cherry, good luck with the procharger. I already tried a F1-R on my 408 and had custom brackets made due to the stock brackets flexing and allowing the belt to walk off the ribs. I also had a manual tensioner so that I could really tighten down on the belt. I spent probably $2000 on belts in about 6 months. I would chunk belts in burn outs, @ the 60' and anywhere down the track and only got about 3 or 4 full passes out of it. I dont think that the 8 rib would do much different, Cog I believe would help. I would say go turbo or twin turbo. I think I am going to make a twin kit for the escalade over the winter. I still have the custom brackets I made for the procharger if your interested, here is a ferw pics i can find of the bracket

 

2toneblown how much thicker did you have to go o0n the new bracket? Also what is that sensor just before entering the TB?

 

should be IAT

 

I bet the reason it was throwing belts was because you had a manual tensioner. For a supercharged application you need a spring style tensioner. As you get higher into the rpms the belt begins to stretch and you need a tension that will take up the slack when this happens. I have the 8rib an was having bad belt throwing problems from the begining. I ended up getting a gates belt tensioner and larger idler pulleys to take up the slack with the belt. I have not had any more problems. I have made many wide open blasts and short burst hits and no belt issues and no slipping.
On another note, that bracket you had made was awesome. I think the easiest way to go cogs would be to change over to vette accesories and get the ATI perfromance cog system or to have a new bracket made to push the blower forward and run a cog off the front of the balancer, which is what I think I am going to do in the future whan I go to the F2

 

i tried it with all different tension on the belt
