That horsepower will be the 'Road Load' at that velocity.
Since rolling resistance is already embedded within the relationship I should be able to reverse-engineer the new drag coefficient.

I'm beginning to see the logic of all this, but I would approach it a bit differently, particularly as regards available wheel horsepower. Most speed events these days have portable chassis dynos available in the immediate area. I'd be very tempted to figure out when my runs were going to occure and have a dyno run done either before or after my top speed testing. Deducing power is a lot less accurate than measuring power.
Perhaps I've been spoiled by having a devoted old race buddy who tests my race car for free, but it certainly would eliminate a lot of guessing(i.e. deducing).
