its a lighter crank pully and tom take it easy some people dont have the time or money to do a turbo swap so they want to get more power any way they can i wish they made some i would be putting them on.

How much HP could you possibly get from underdrive. I have done dyno pulls on 5.0 mustangs and can't find any HP gain. I meant no harm from my post. I hate people getting ripped off with parts that claim tuns of HP gain. They do make them for the 5.0 they are costly and don't gain any HP. All they do is slow the wp down and cause the alt to charge less. Not a good idea on a street car. Their original design was for a track car to keep pump and alt turning slower. Put the money twords a cam change. Best bang for your buck. Hay i am cool not trying to put anyone down. Peace TOM
