The torque and HP curves are what I was preparing when I stumbled upon this. I was just subtracting out the coast-down forces to get the power-to-wheels curves when I realized you could learn some interesting tidbits like the Cd by simple math. And the tire coeffient seemed much more prone to error so I left it out, but you're correct 0.08 is a good number to use. Exactly right, Chris.

The tyre co-efficient value is hard to come by, but a good base is 0.08. I have the equation somewhere, I should dig it up. BTW, great piece :) Converse to this, by using the aero drag co-efficient, and tyre co-efficient you can measure torque and hp.
