Ford got in trouble in 99 with the 99 Cobra. Which was rated at 320hp. Owners were finding much less when dynoing including me. So I guess this time around they got smart. Although the underrated the terminator also.

Yeah, they underrated the Termi's by about 30 or so HP. They ended up putting a few shy of the advertised crank hp to the rear wheels!

Nowadays, so many tricks can be played on a dyno to show results you want. Whether the '11 GT shows up at or over the advertised "412", the car is no doubt going to be a fast Stang and stock for stock be able to hang with the Camaro and Challenger!
