I can't help but wonder if the later year cars, like 03 & 04, made a little more HP? The reason I ask this is the following, when comparing my car to one of my buddy's (01 stang) we noticed the following:
1. my car (04) factory 80mm mass air (earlier ones were smaller)
2. My injectors are purple (just different than his)
3. Our factory pulleys were different (my alternator pulley was noticably smaller)
4. My car had a much more aggressive sound with the stock mufflers than his did stock
And thats all I can think of now, but if that guys numbers seem a little high, say maybe by 10hp, the points I mentioned could probably account for 10 hp???
Just a thought, maybe someone else can throw in some other differences they have noticed
If you both had the same size crank pulley than your alternator would turn faster than his.3. Our factory pulleys were different (my alternator pulley was noticably smaller)
