easiest way to tell is to see if it's smaller than your stock pulley. I can't remember how much they are new but I think it's around $200 or more. It's more of a freeing up horsepower mod. Definitely frees up torque as there's less drag on the motor.
I am curious, do you see the same gain regardless of your starting point?
For instance, if you see 8-10 rwhp on a fairly stock setup, do you still see the same 8-10 rwhp on a 500 RWHP car or do you see more or less?

From all the LS1 modders I've talked to, it's more of a bragging and dyno queen mod. They all agree you'll notice nothing in actual track times from it. But personally I'll still pick one up eventually. It's just nowhere near the top of my priorities list.

It was 12rwhp & 12rwtq. But close enough.
I paid $210 ish for it shipped from Speed inc., Well worth while mod.
