Yes by spinning the accessories at a slower rate, it reduces the load that the engine is bearing through the serpentine assembly. Allowing it to make more horsepower.

~10rwhp / .1 reduction in e.t.

The SLP pulley is also light and takes off weight from your rotating assembly.

Yes and slp's pulley also features the taller walls so you wont have to worry about throwing belts.

It free's up horsepower that would have been spent on turning the acessories faster, but no it dosnt technically creat any additional horsepower. You will see a 5-10 HP difference on a dyno.
