Can't you just estimate the top speed using the figures gained at the one mile mark ?
Cd,that's a good question and I'm not sure about the answer.
Without a dynamometer survey I don't actually know the power.Without the top speed I can't know the Cd if the engines at rated power,adjusted for density altitude on race day,to make sense of the acceleration.
If I know the rpm at 1-mile at the Texas-Mile,then do a dyno test at that rpm at WOT and adjust for Texas-Mile weather I might 'fix' the power at that rpm ,then extrapolate.
If I go to Bonneville I get to make the runs,maybe long course,plus I get to do all the other things and see all the things typically only seen at Bonneville.
It's a pain alright,but I get to do Battle Mountain also,so in a way,it can't be beat,nasty salt and all!
