This is a neat little calc. I haven't had the time to plug in the numbers yet so knock yourself out!

6spd and base car= 3.27 axle
srt6= 3.07 axle
6th = .838 ratio
5th automatic srt6= .831

effective tire ratio is 25.7", add about 7psi for measuring at top speeds, mark tire at centerline on floor, rool car forward until the mark meets the centerline again, take distance and divide by 3.14.

the Cd= .37

frontal area = 20.56 sqft

all you have to do is enter in available hp at rpm, 215hp at 5200rpm for stock crossfire. srt6 is 330hp at 6100rpm.
