I'm really interested in unlocking 10-12hp with the underdrive pulleys but I don't want to end up buying them to gain nothing. For all that has used them, do they really work like they say they do? Is there a noticable gain in the hp or really no change?
SCP 2 Piece Accessory Underdrive Pulley Set $105
Includes a new alternator, and crankshaft pulley.
An easy bolt on that yields 10 to 12 HP. Less parasitic drag from your accessories means more power can go to the rear wheels. These are no gimmick...they work like a charm!
