Getting started with Aerodynamics

[John S]

Thanks for the responses guys. A lot of food for thought here! My intention is to ensure that the car is manageable at hi speed. I would like to open track the car at some point and I just want to be sure that the car stays planted at speeds in the 130-140 mph range (if I get it up that fast)



Novaderrik is correct, the radiator has a sealed airbox and the only air into the radiator is through the grill. With the sheet metal work in my engine bay and the hood I do not believe that there is anywhere to vent the incoming air other than down and under the car. Whether it is enough to cause any high pressure under there I do not know. Also he confirmed what I thought about the chin spoiler, but again I wonder how effective it is and can it be improved.
I'll try to take a few pictures of the hood in the next couple of days and post them up as well.
