Re: aerodynamic drag and body style
non-issue! unless you are running 130 mph in my opinion

Re: aerodynamic drag and body style
Seems like a lot of over thinking for an eighth mile bracket car.

Re: aerodynamic drag and body style
Lee, overthinking is one of my high skills. And I think overthinking is a common trait for many hot rodders. I point to stockers, got to be one of the most overthought packages ever. However, overthinking often leads to success.

Re: aerodynamic drag and body style
When considering aerodynamics of drag racing cars/trucks, etc. The assumption of aerodynamic drag only has an effect at speed is incorrect.
 One can think of the issue becoming important at any speed over 40mph and the aero drag resistance is exponential to the speed very closely following the square law and more. That becomes a lot of free power by cleaning up (legally of course) the aerodynamic drag for the vehicle. Lots of rules of aero thumb to apply, but it is best to study and learn what can help with the selection of vehicles and how to improve them. An example is: external rear view mirrors cost about 0.6% in drag power. Regards, HB2  Dissident |

Re: aerodynamic drag and body style
Back in the day a few stock and S/S cars ran a vinyl roof claiming the pebble on the texture was worth some MPH,however small the gain was.FWIW,Jason Line's Buick GS has a vinyl roof...gsa612

Re: aerodynamic drag and body style
I think 80's Monte Carlo with SS nose has CD of .34.
Question: If a car has more downforce then lift would go be faster if they were made equal? Last edited by Jeff Stout; 08-07-2020 at 04:01 PM. Reason: more |
