The Ford GT typically loses about 5% through it's transaxle and half shafts, for example, the GT is rated at about 550 hp depending on ambient air temperature and produces about 535 Hp at the wheels +/- 10 hp. A typical Cobra with 1:1 transmission gearing (top Loader) loses about 15%, so that 550hp would be about 467 hp at the wheels. The solution is a much more efficient transmission and differential, no drive shaft and CV joints instead of U joints in the half shafts.
There are lots of other factors but the big ones are transmission and differential.
This assumes that the engine was engine dynoed with the proper exhaust and ancillaries.
