For example, when I posted earlier from the thread about designing duct work, it pertained to the student race cars that don't see high speeds. The consensus with them, was that exit speeds didn't matter because they didn't obtain speeds where a difference is air speeds would be noticed. I'm on my phone right now, I'll try to post something more substantial tomorrow from my computer.... But I was just wondering if you knew off the top of your head? I mean that would be a lot of variables that would need to work perfect to even match a single speed, much less all speeds??

Above 20-mph,the coefficients of drag for all the components of the car would be fixed,up to around 250-mph,when compressibility effects started to show up,so all their individual behaviors would be constant.
As long as you tuned in a turbulent boundary layer,everything would track in the same proportions.
