Pulleys

[mosrt10]

I've seen a few members that list underdrive pulleys as one of their mods. Who makes them? What kind of gain am I looking at. I had a set on my 5.0 and seemed to add a little but nothing overwhelming. It did cause it too run hot on days it was a bit warm here in the midwest.

The only ones I know of is the guys with the paxtons bumpin up the boost.

But you could pm Silverback and ask him, I think he actually found some pulleys somewhere ,but its been awhile:dontknow:
