arent drag racing runs diffrerent ratios from track racing?
you have to estimate the terrain as well, as for example:
after corner got uphill? downhill? sweepers? long corners? chicane?
yeah la hp is the max factor but for track racing torque plays a very important part too...
as for hondas i got the specs, but sorry ah...trade secret. generally for a guideline, a longer final drive ratio from an aftermarket product is needed in sepang due to it's long straights. you figure the rest.
