UDPs are, in my mind, one of the best mods for a small motor like the Zetec, SPI or Duratec. Maybe not so much the Duratec for all the extra torque it has.
UDPs don't "add" power in that they drive accessories slower and at an easier effort level than stock pullies. They "restore" power the engine has lost due to driving those accessories at stock levels.
I had a 50% crank UDP on my SPI. It was easily the best mod I ever did to that car.
