More heat? the blower won't be turning even 1rpm faster than would be with stock pulleys. Its called not wasting a $250 underdrive pulley. You must be a turbo guy.

Besides that they use a smaller pulley to go up in stages with the power so along with more heat there's a lot more air but that's irrelavent to my earlier post.
I didn't read the post thoroughly enough to put it together that one pulley percentage would cancel out the other. All I did was immediately zero in on the "overspin the blower" text. Yes that is my bad for not reading the entire context of the message but but that is certainly no reason to prefix yopur answer with a degrading barb. And don't even try to say that wasn't your intention because I just won't buy it.

As someone once posted here previously that hiding anonimously behind a computer screen certainly makes some folks awfully brave.....and just plain rude
