[DeTomaso] Other Aero Issues

[John Maffeo]

I've also heard that the Indy cars are working with the tire manufacturers to produce dimpled tires. Preliminary tests with re-treads applied to the tire walls have been very positive.

  I suggest that you do the entire car in a dimple finish, similar to a 
golfball which has been scientifically proven to reduce drag. I would pay particular 
attention to the underbody surfaces and all areas that lead into the radiator 
opening. Considerable reductions in drag can also be realized by dimpling 
surfaces of the suspension, springs, a-arms, etc.

Wheels and wheelhouse inners can also be done as this is a very important 
area since there is a lot of turbulence and increased drag caused by wheel 
rotation.

You should also tape up any body cuts and reduce the radiator intake to as 
small an opening as possible. If you have a fan shroud you can compute the front 
air intake and close it off to match that in square inches.

It is too bad that you do not have a way to measure all of this but what the 
heck you already know it is in the right direction.
