UD Pulley & Boost

This might be a stupid question but since i have underdrive pulleys on my truck. Will it effect how a blower pulley will turn?

Yeah, it will slow it down just like all the other accessory drives. You would have to put a much smaller pulley on the blower to make up the difference. A smaller pulley on the blower can cause belt slip issues. Best off if you run a blower to put the stock crank pulley back on.

yep as mj says...I bought a 6.0 with a brand new UD on it...sold it cause I have enough of Murphy Law problems to deal with...trying to work out those ratios and belt slip wouldn't be worth the gain of the UD...IMO.
