MM&FF claims they put an 05 GT on a dyno and got 295 RWHP. That menas its more like 320 - 330 HP at the crank.
The Ford engineer I spoke with said: "It has a very robust 300 HP".
I tried to pin him down on how much HP it really has. I mentioned the MM&FF 295 RWHP #. He got a startled look on his face and said "It's better than the Mach 1 engine. In some ways A LOT better. It has a much better torque curve."
So I tried to pin him down again saying why are you rating it @ 300 HP when it's sounding pretty clear that it has a lot more. His reply was that the official ratings are chosen by marketing for many reasons. Insurance rating being one of them with other reasons being that they want to make sure that they never again have an engine (like the 01 Cobra) that would not meet its advertised HP rating under ANY circumstances.
I have the feeling that the 05 is going to be a screamer!
