Wheel spin in 2nd

samb03 · 11-17-2010, 04:39 PM

You need to think about gear ratios. for the manual 2nd gear is 2.324 w/ a rear final drive ratio of 3.69. multiply those to get your absolute gearing = 8.576. Multiply that time the torque the engine is producing. 270lbs @the crank at 5200rpm. This makes a grand total of 2315.3 lbs/ft so I guess I that is were tire slick comes from.

3rd gear is 1.624x3.69= 5.992x270=1617lb/ft.

the 96 trans am w/ 6sp manual makes 325lbs@2400 (according to MSN.auto) 3.42 final ratio (there was also a 2.73 rear ratio) and 1.78 ratio second gear. make total torque multiplation of 1978lbs@ peak torque in second gear. If you hit it hard and are above 2400 you will have less torque.

I know theres torque numbers aren't real world numbers but they are the best I have to work with. And it is more about the principal then the actual figures.
