OK guys, I was making some strong street pulls last weekend and had some issues. Here are the basics of my engine. forged LS6 with an Incon twin turbo kit. I've got it crankin 750rwhp. problem was while doing some hard pulls I spewed coolant out the cap. Ok maybe I need a new cap..but at the same time my ribbed belt for alternator ,v water pump ect jumped and just caught the edge of 2 pully's. car got hot , didn't over heat..i guess my question is, has anybody with a boosted car had the belt take off like that/ if so , how did you correct the issue?

 

Just had that happen on my car switched to a manual tensioner haven't had a problem since. I bought the katech and swapped the pulley for a smooth pulley

 

Manual tensioners do seem to work well for the accessory drive.
