Back about 5 years ago my friends 4.6 Cobra (300hp 4 valve) didn't trap 90mph. I have seen a viper post less than 90mph.

Now, if you have an SVO or a GT turbo (most likely both with more boost than stock) a 4 cylinder mustang is not putting down that kind of mph.
See sig. Not trying to start shit, just saying that I did trap close to 90mph last year on a 15.92 pass. The trap speed is good for low 15's, but my driving was obviously only good for high 15's. Trap speed is what indicates power, assuming nothing goes wrong on the run, and is a key part of the information about a pass. Unfortunately, most people tend to omit it and just say the ET, which really doesn't mean that much by itself.

Elevation or not, a C5 should trap in the mid 90's based on horsepower alone.
