After learning a bit more about "hopping up" electric r/c cars, I've seen that two different Pinion and Spur gear combinations, with the exact same final drive ratio can actually have a major difference on the motor temperature and performance during runs.
Well, how does this all come into play in full scaled, gasoline cars? Let me explain my question...
If you had a car with a low rear end ratio but big tires, with an overall ratio of 1:1 (Tire rotates once for every rpm, [just to make it easy] :???
And you had another car with a tall rear end ratio, but little tires, with an overall ratio of 1:1 (And do they have a name for this? For the overall ratio after adding every factor?)
And can this same rule be applied to matching tall transmission gears to low rear gears, and vise-versa?
Both will cruise simultaneously, but what would the pros and cons be of each? There has to be some kind of performance difference dealing with rolling resistance or torque multiplication of some sort, but I just don't know enough about physics to put all the peices together. Has anyone ever read about or discussed this before?
