Having been on both sides with a 93 Mustang GT and 93 Mustang Cobra previously and my 92 GSR I can say that the reason most people don't do as well in Imports is the powerband. While my Mustangs both redlined at 6,000, if i shifted them at 5,000 it didnt really make much difference, they had very wide powerbands. My Integra may redline at 8,000, but if i shift at 7000 it probably loses at least a second in the 1/4. For example, at the track my normal trap speeds are 89.7-90.1 in the Integra. One time I accidently shifted early at 7700-7800 not paying attention and that run my speed was only 88.7.
