runningmole said:Not to be a jerk, but your 'schematic' is off. I have 3.55s w/ 16in rims. 65 mph in 5th gear is 2,000 rpm. 140mph is way less than 5200rpm....I did it (and punched a whole in a piston )
The numbers I posted are based off the corral.net gear calculator and jive with the RPM and speed readings I've noticed while driving my own car. I can't speak for your car, but they work for mine.
Keep in mind that corral.net lists several different transmissions, so you may not have the same gear ratios as I do.
