UDP?? I see all kinds of posts on it and usually related to gear ratios for the rear end, but feel like a tard cuz I dont know.

UDP is underdrive pulleys I gained 4 RWHP which turned out to be $75.00 per pony.

Its the pulleys on the crank shaft and water pump. UDPs reduce the drag on the engine and you gain HPs

I knew what an underdrive pulley was but never made the connection that it was a UDP...never heard that until I came onto the forums. And I figured if I didnt know there had to be others so why not ask! That's sorta like afk, roflmfao, bb, etc....
