OK, different car, different engine, but the Saturn guys at SC Racing took the whole darn belt off for their first dyno run and gained a whopping 3hp. They figured the best they could do was about a 20% underdrive for a whopping gain of .6 hp on something that is probably detrimental to engine life over the long haul. Even if it isn't, it's hardly worth the money.
In their words, "In racing, horsepower talks and marketing bull$hit walks."
Yes, but they still had the heavy weight of the pulley on there. Yes the pulley radius is smaller than a flywheel, but there is still a 5 lb chunk of steel at like 4 inches off axis of rotation. That is roughly equivalent to taking 1-2 lbs off of an 8 inch radius flywheel.
