I strongly dissagree about the fact that having 4.11 gears in the rear of my E36 M3 will show an increase in rear wheel hp as opposed to having a 3.23 diff on the car.The ex. you gave about the C5 and the E46 M3 does not equate to the E46 M3 putting down similar or more hp to the wheels than the C5 because of the diff.No offense but that does not make sense,if that's what you are saying.
Alot has to do with the characteristics of the motor and weight + rear axle ratio of the two vehicles .
The two vehicles are very close when it comes to rwhp 270-280(M3) vs rwhp 295(Corvette).This is not because of the differential.How they run against each other off of the dyno can be attributed to weight,engine character,and gearing. They are also close in rwhp.
Lets talk apple to apple
On this example E46 M3 using 4.11 vs 3.23 diff
4.11 will produce more rearwheel hp number.
I am getting tired saying smething over and over again.
If you can't agree too bad. I'd suggest to do more reading.
