This was the reason I wanted to build a wind tunnel to determine the distribution of forces on front and rear axles.
Sadly setting up a function to simulate the traveling 100+mph boundary layer on the ground (moving belt or a complex air blowing system) was out of the budget.

@rb1957 IF that ends up being the case I may have a v2 design later to try venting out similar to what JCB Diesel did on their land speed vehicle.
If the design creates too much drag with the suspended airfoil design then I would simply build the car like everyone else has where there is a...
I have read about the front shape taper being a tricky thing to get correctly. The general idea/take-away I got was that a more rounded shape is safe. Setting up a sharp leading edge incorrectly could be dangerous from what I understood.
This is a better angle/view to see the shape. I am...
I was under the impression it was the airfoil chord length. That does change the perspective of the results for me if that is the case.
Regarding the drag forces I believe it is in relation to the distance between the airfoil/wing and the ground causing additional drag. At some point...
@3DDave I was not aware of that concept. I will remember that should I re-visit the wind tunnel dream.
@WKTaylor thanks for the link. I believe the link you provided might get me headed in the correct direction. This one specifically has very relevant data for me:

Hello all,
I believe this topic is best suited in this aerospace region of the forum although it relates closely to Automotive.
Does anyone have good details on distances from the ground in relation to drag and ground effect of an airfoil?
I wanted to build a wind tunnel in the garage this...
