1. Being an engineer is being an applied mathematician. We go to school to get it right, over and over and over again. Eventually it becomes second nature to us, thus doing the math for a real world problem (LIKE THIS ONE) give numbers that (when all other factors are negligible) will give you minimal difference.

2. I still think you fail to understand, experience is biased no matter how hard you try and make it not be.

3. Here's a question from my physics textbook chapter 8 rotational kinematics, (the same principles used to do all this fancy unicorn work with the driveshaft);

The angular speed of an automobile engine is increased uniformly from 1170 rev/min to 2880 rev/min in 12.6 seconds. a) find the angular acceleration in rev/min^2 b) how many revolutions does it make in this time?

can you see how the math can numerically quantify a real world problem?

4. You're looking for approval for buying the driveshaft. You keep wanting someones experience review for it, yet this thread basically disproved its ability to significantly, even minimally improve acceleration. You've already made up your mind about it and refuse to believe that it doesn't do any good.
