you might know this tip already but ill throw it out there for you.

if your having a belt slippage problem at wot buy a new belt. coat that belt with vht prior to the pull, letting it tack up good.

make your pull. you can then coat your other belt and prep it while shes cooling off. swap belts on each pass or pull...will show you max boost and should not slip
