PM me for pricing and availability!

10-14 hp from a stock diameter pulley???

Even at the crank I'd be surprised if it made that much. I dyno'd the Stillen UD pulley at +5whp on a DynoJet. But like you said, we'll find out soon enough.

Yeah not too confident in their numbers either, but we'll see. I would expect gains to be in line with the Stillen pulley.

Except the Stillen one semtex dyno'd was underdriven, the unorthodox one isn't. Should be even less.

Not necessarily. It will depend on the weight of the Stillen vs. the weight of the Unorthodox.
