This is like guessing the loto numbers. Way too many variables. My guess is 250 hp at the wheels turning mid 14 teens.

I wouldnt beat on the stock 4 cylinder 5speed it's made different than the 5.0 5speed and wont handle the torque as good. He'll eventually spatter it if he beats on it constantly.
