how much horsepower would a stock 1996-1998 Mustang GT have and how much horsepower would be coming at the rear wheels?

 

215HP for 96-97</P>


225HP for 98</P>


Around 180-185RWHP</P>

 

If you have an automatic, it'll have considerably less at the wheels. Automatics have more parasitic loss than manuals, and Ford AODEs are even worse than the norm. Figure 170-175hp at the wheels for a stock AODE 96-97, and 175-180hp at the wheels for a stock AODE '98<IMG src=smileys/smiley2.gif border="0">

 

20% for autos from the crank to the wheels. 15% for manuals

 

I've seen as bad as 22% for automatics...<IMG src=smileys/smiley11.gif border="0">

 

Those are all just general %'s. It will vary depending on the drivetrain and wear and tear and even the fluid types used. Everything sounds right.
