I wanted to see if anybody else ever noticed this, I just did last night. The 99-04 GT PI cars are rated from the factory at 260hp, but if you look at all the mustang mags they allways get around 215 at the wheels for a automatic and 230 or a hair more for the 5 speeds. In the april 2004 issue of Muscle mustang and FF they compared the GT, March1, and cobra ( this is what I was looking at when I realised this) they dynoed the GT and got 214hp and 265lb of torque, now with a 23% loss thru the automatic that would put it at 280hp not the 260 ford rates them at. If you look thru the mags for the articles the stock 5 speed cars usually make around 230, and with a 15% loss this would be around 280 also. It is a known fact that the cobra's were underrated from the factory, so am I doing something wrong on my calculator or are the GT's a little underrated too?
