Have you swapped the rear pulleys side for side?

What's your rear drive set up now? I'm guessing you're underdriven with a 3" pulley on the jackshaft driving a 3.49" pulley on the back of the blower. If so, just reverse those two pulleys to make it overdriven on the rear. Don't have to buy anything, just swap the pulleys side for side. If you're dead set on cogged rears, get an overdrive set, not 1:1. You'll have to clearance the fuel rail next to the jackshaft pulley if you use cogged rear pulleys. You won't have to do that if you use the stock rear pulleys and just reverse them. It's close, but doesn't rub. Overdriving the rear pulley set is something you have to do (not optional) if you're trying to get the most out of a jackshaft TVS2300. The overdriven rear pulleys allow you to use a bigger front pulley that will result in less belt slip and still have faster blower speeds. It's a win win.

Going from underdrive to overdrive on the rear pulleys makes quite a big difference in blower speeds. You'll see more power and boost. Have your tooner check it over before going WOT.
