REGARDLESS of what the hp is, this mustang can be 150 hp for all I care, all I can is mustang can pull great times with their base HP. The GT pulls 13.7, wow, thats right up there with a Z28, and its missing 50 hp, the cobra pulls 12.56 (11.99 with gears, exhausts, and intake) and guess what? with early tests this car pulled 12.9. Now I say thats impression for a 300 hp dont u think???
