Default 15% overdrive crank pulley
Has anyone here went up from a 10% overdrive to a 15%. How much more boost did you gain? How much more power?

Wasn’t aware anyone made them? Or that it would even fit with truck accessories.

I would be surprised if it fit with the factory waterpump. Looks like 1-1.5psi in most cases going from 10% to 15%.

Wow, on a 10% there was next to no room at the water pump pulley with the belt on. . Can’t see how that would fit.


fyi. Once over 20,000 blower rpm my TVS didn’t gain much at all. It picked up boost but was so far out of its efficiency range power didn’t do much.

It fits if you route differently, according to the guy at LSSimple
