Have had mine on for a few weeks. My butt dyno doesn't notice the difference. I installed a new OE water pump and low flow t stat at the same time so i have been watching the temps like a hawk. No noticeable difference in the Florida heat at all.

Butt dynos lose their measuring ability as the starting HP ratings increase. :-P
You're not going to notice a 20-hp increase on an engine with 300+hp as much as you would on a 200-hp car. (Not saying the pulley increases power by 20 hp)

Less parasitic loss so more power to the transmission and beyond. Claims of 5hp from some vendors - not an increase in power from the engine, but more to the wheels. It is also supposed to prevent spinning the pump too fast causing seal damage on cars that are raced or driven at high rpms. These are just me repeating vendor claims. I have no way to prove any of it.
