When ET and MPH Are Not a Match?

Another twist to it all, which is normally the opposite of most cars that could do with some improvement on the chassis is if your car 60ft's real good, like say a 1.26 60 on a 9.90 your probably only gonna go in the 129>131mph range and will throw your fwhp mph/weight calcs out. On a lesser chassis that would be in the 135+ mark and a 60 in the 1.38 range, thats the only time the Wallace calcs aren't as accurate as they were based on your average good leaving car.
