FDR Equivalence Question
Amongst our club members, we have a debate going that I would like to get others opinion on.
Given a specific final drive ratio, say 3.7, are there any differences in the performance of a car using different combinations of spur and pinion to achieve the same fdr?
For instance, an FDR of 3.7 can be created using a 96t spur and a 49t pinion, or you could, for instance, use a 92t spur and a 47t pinion. Would there be any differences in performance? Is there a difference in load placed on the motor, such that one gear combination might run cooler?
Our members have a number of different opinions on this, so any thoughts are appreciated.
