=8,000/14.268 * 3.14*225*.5/25.4 + 16 * 1.57828283 * 10^-5 *60
=41MPH with a 4.1 and 44 with a 3.9.
. . . I think.

Well you can avoid the calculations all you want. They don't lie. Just because you have a limiting factor doesn't mean that the car still isn't capable of performing a certain way. The only limiting factor here is the factory tune of the ecu. Anyone with a aftermarket ecu can hit those speeds in those 3 lower gears easily.

I have found the Road & Track numbers very close on my car (at least until I started running taller rear tires).

Off topic quote from that article:
"More important some 200lbs have been shaved from the curb weight.......Example, better air flow to the radiator has allowed engineeres to reduce it's size, saving 3 lbs."
Better air flow?
