At the annual swedish camaro club racing event it broke after 50 foot http://home.koping.net/u3243a/tillfalliga/belt.jpg it also smashed reducer to the heater core so it was no more racing for me
guess i have a total of 300miles on that belt (no slipping) have done a little racing an tuning, guess it should be equal to 15-20 1/4 runs...
should i expect this to happend again or is it just bad luck?
edit: 7,65 /4,13" pulley combo on an F1 13-14 psi on oure 383LT1,ported TFS heads, bauer racing custom cam (32x/33x), FMIC, water/ethanol inj..........

Bad luck. SC belts are supposed to last a long time. Alot of times they dont tho.

Use gatorback belts

 

You might consider higher octane fuel or a more conservative ignition tuneup. Detonation kills SC belts.

 

can you elaborate on that more? how does that kill belts?

 

Because the crank is no longer rotating smoothly in the direction of normal rotation. It really shows up with a cogged belt. People who have had detonation problems killed belts until they got the tuneup nailed. This continues to be an issue. An F1 is a good size blower and it appears to be a new installation. My money is on the tuneup.

 

dont think its the tuning, have 25-24 degrees from 4500-6500, runing 93oct, 8.5 comp, FMIC (24x12x4 core), water/alky, 11.8 A/F, 2step colder plugs,13-14psi boost.
havent seen any knock counts on the scanner at WOT.
have tried it widhout the water/alcy and thats no problem either...

But i have hit the revlimiter a few times so the belt could have been damege then maybe

Havent tought about detonation should be a problem for the belt, have seen a cog equipped car that used 1 belt for every 1/4 pass, and they have had a lot of tuning problems... so i guess that could be the problem...

about gatorbacks, i cant find them here in sweden, can you tell me were in usa i can order them ???

 

That sounds like your problem.

As far as gatorback belts, try www.beltsforanything.com

Good luck,
