Belt shreading to pieces.
Belt shreading to pieces. I have a Prochager brand 4" pulley on my car now and it shreaded the belt. It looks like i took a razor blade to each individual ribs on the belt. The ribs are pretty sharp, alot more than the Richard pulley. I also added an idler to give it almost 90% wrap on the blower pulley. The idler seemed to help alot but it shreaded the belt on the 1-2 shift on the first pass. It kicked *** for just first gear tho. Off the foot brake it 1.42 6.62 at 104.4 just in first gear coasting from half track. I seen 12- 13 lbs before it broke. I would think a maxed out F1 would make more than that still. Anyone think i can just have the ribs machined down a lil bit? I'd like to get it to run bottom 6's before the seasons up and i switch to my 50 mm cog drive over the winter. I still think the times are pretty sad for a 400 inch motor with 12 lbs of boost. Also got a race weight of the car its 3610 with me in it. I go for 185. SO it needs to go on a diet bad. Any body have in info for me on the pulley? Thanks Justin
All the procharger pulleys I have and had all had sharp ribs, but never had a belt shreading issue due to the ribs...just belt slip issues from a flexing bracket and not enough tension/belt wrap. Maybe your running too much tension to have the belt shread in that way or it was massive slip. Did you smell "burning rubber" when at WOT?? That's a dead giveaway for belt slip at the track.
Cog drive huh....good luck I tried a cog set up but the belt wouldn't last past the tree before it was stripped of all its teeth....tried it loose, tried it tight the belt just wouldn't live. If you want cogs, I have a full set...100 bucks paid 500.
SDCE is your answer though, get with them, they will provide you a set up that will be able to handle the almight F1.
Hope this helps a lil.

What size cogs is it. Like an 8 rib width size? Funny thing is with the belt i have i didnt even have the tensioned cranked down it was just tight to begin with. So i dont know what happened. What diameter pulleys are the cogs you have. I may just get them from you its worth a shot.

DO NOT GO COGS 
Get the SDCE 8 rib tensioner
I have an F1 on my car, I'm running a 3.4" blower pulley, and a 7.25" crank pulley, 15psi at 6000rpms so far, should hit 16 hopefully, no slip at all
Should hit the dyno this week

Yep, I first what I said, and second what ol Bos says, call SDCE...
As for the cogs, they are a 71T and a 31T the cog belt width is almost identical to the 8rib i'm running now....but I would stay away from them PERIOD.
Your cog set up might work really well, but the SDCE set ups work VERY VERY well, I'm seeing 15.5psi right now with no slip.
