velocity / aero power
Just for giggles I ran your velocities through the aero power vs V-cubed function.
Compared to aero power requirements at 65-mph:
* 70-mph requires 24.9% more hp.
* 75-mph = 53.6% more
* 80-mph = 86.4% more
-----------------------------------------------------------------------------------------
When you compare 80-mph, to 40-mph, you get your 8-X increase.
1) you're hitting twice as much air
2) you're hitting it twice as often
3) and you're hitting it twice as hard
