I'm now working on gearing to help select a suitable gearbox and final drive ratio.
I've been reading Carroll Smith's Tune to Win but there's only two pages there on gearing. I'm stuck on this bit though:
Looking at the engine power curves with a view toward gearing, a couple of things become immediately evident. First is the fact that, on any given race track, we want our maximum rpm in top gear to coincide with the maximum BHP of the engine- as installed. If we don't reach that rpm
because we are geared too short, we will give horsepower away and will lose both top speed and laptime. If we exceed the rpm by much, we will sacrifice horsepower again with the same result.
I don't understand how you can make maximum RPM of an engine match the maximum BHP. The maximum BHP is at a certain RPM and the max RPM is elsewhere so how can these be matched?
If anyone can also suggest other books that cover gearing, that would be good :)
