I was just wondering if anyone has the MPx underdrive pulley, and how much it help from stock. ON a sxt or se model engine. Also if anyone knows how much hp it adds.

 

It doesn't really add power, per se. It reduces the drag that the accessories put on the motor, thereby, freein up horsepower that's already there. It's probably worth about 5 horses?

i just got my pulley installed by midas for $106, i tried doing it myself but that damn stock pulley wouldnt budge, it doesnt add hp it frees because of its size and weight, kind of like running with light shoes instead of running with boots,
yea i noticed it has more pull after install
