Cool that you are using mock ups VelociTT. Interesting.
Yeah I know exactly what you're talking about, the z06 was one of the cars I was looking up when I was pondering about all of this. The jaguar XF is the same way, believe it or not. Took it to a friend's shop the other day and we put it up on a lift and we both said holy shit. Flat as can be under that car!the difficult part in doing this with our cars is the design of the underbody and location of exhaust. The vette is designed so that the exhaust is in the tunnel and right above it is a cover for the torq tube. so it allows the floor pans to be perfectly flat where the passengers sit. with the tranny in the rear on those cars, it allows the bell housing to be smaller and for the long tubes or exhaust to wrap around it and be maintained in the tunnel.
if this thread is still going over the next couple of weeks, I will get some pics of the vette. I am getting ready to do a clutch job on another and the whole IRS and rear needs to be dropped out for that.
no, I haven't done anything, but I figured I'd post that up if anybody had searched for it in the future. Not a lot of good underbody shots of mustangs on lifts on the net that I ran across.Really cool aero simulations VelociTT. Have you done anything new lately?
If anything I would think it would create more drag.
no a properly designed undertray would create less drag, and actually help cooling by forcing the air through the radiator and whatever cooling ducts you had in the car. All high-end cars have ever seen have had an undertray. I have thought about this for awhile now. I would have thought somebody would have already designed one for these cars.
1.I have a question that is nagging at me: Wouldn't putting a tray under the front end of the car create more instability in the front end, because of the compression of air under the car producing lift on the underside of the front end?
2.Hence the reason to put a front splitter as low as possible at the front of the car, to keep air from entering under the car in the first place, limiting this condition. Just a question.
I have always wanted to make a flat undertray on the Mustang, would help gas mileage and top end speed where a vette or other sports cars have the advantage.
The newer mustangs do have an undertray.
As you can see from the Boss one, there appears to be some venting fins that might actually extract heat in a vacuum style method due to the rushing air from underneath. I have not seen evidence of added vents in the front to redistribute air movement.

The hood vent on our cobra's are designed to be in a low pressure area of the hood. And since we would effectively be increasing the pressure in the engine bay, with Racebronco's theory, we would be causing a greater amount of air to flow out of the vents, which would also promote cooling by decreasing the pressure behind the radiator thereby increasing flow.
