i have a race car with a zx10r engine. i run road course, turning left and right, shifting up and down. i'm trying to figure out the rpm range for each gear 2-6 that will provide the best performance. i need this to determine the best gear for any particular place on the track. anyone out there who can help out?

Well, peak torque is at like what 8700rpm's or so...peak HP is way up there. I would try to keep the engine in that range...try not to let her drop down too far in the r's. Sorry, that's all I got. :dontknow:

first question: have you dynoed your car? if yes then:

find how much RPM tour engine drop for each shift in the upper rpm.
once that id done, try to integrate your paer curve (calculus Math).

an easy way to do this is to find someone who as a CAD software (I use SolidWorks), reproduce as acurately as possible your power curve in the software then put 2 vertical lines (drop of rpm) to find the area that as the bigest surface possible.

you can do it on papper too but it's not as accurate.

repeat for eache gear and your done...

if you have questions feel free to contact me
