Yup, the stock car is geared like it has 450ft/lbs of torque from idle on up.

Great thread and learned much my question is...i dont want to change 2nd as it has plenty of tourque the few times I have to go to it and frankly do not want to change 6th as I like gas mileage on highway ..and do not feel i will run out of 5th even after regearing...right now get to 135 at Mid Ohio and that is failry early into 5th. So i am thinking of regearing for only 3rd, 4th and 5th......i do Mid Ohio, Vir and Putnam so far and find that except for the slowest turns and the end of the straights i am primarily in 3rd gear for most of all laps and think this regearing will really help.... i would expect to have to do a lot more shifting from 3rd to 4th etc but am convinced the tourque would greatly improve.......

I have been told by a reputable shop in town cost would be about 3 k......question is what else should be done if i do this while they are in there ? I do not have the lightweight flywheel is that worth it and how much approximately would that add to cost ?
Is my thinking rational or am i up too late or both

thanks in advance for listening and looking forward to hearing replies espceiclly from Steve R if at all posssible. all input is welcomed and appreciated

My previous 993 had a custom built box with a tall 1st. Yes, it will bog down a bit off the line but most importantly, it will eat through clutches if used mostly or exclusively for street. As Steve said, tall 1st is only a good idea for track-only cars.

John Wright hear in Cincinnati convinced me to also change 6th as the drop would be too much as shown by your chart.....thank you for your reply !!!!!


He wll have Brian Coplan do the work ....

Thank you very much !!!!!!!

Huh? The charts will be identical if you change tires, excpt that the max speeds will be more or less by the % difference of the increase or decrease in rolling radius, in this case the difference is pretty small.

It's not as nice as Bill's but anyone can download a gearchart and run their own specs for their car.
