FWIW, the pic was gotten from http://www.mira.co.uk/ which no longer has it up so if anyone in the UK wants to get more info from them as it looks like they have done more testing that would be awesome, but I doubt they'd share it for free, but you never know. FWIW, their test facilities look awesome.

My explanation was sound I think the speed that was simulated at is not very important. Everything is relative, as the car speeds up so will the air in the places shown. What is important is that it shows you where your potential high and low pressure zones are.

no thats not true. If energy was linearly related to velocity then it would be, but its related to velocity^2. Thats why theres laminar flow and turbulent flow

Looking good Chris!

Are you still going with the Home Depot splitter or have you found something better? I picked up some conveyer belt the other day and plan on using it. We'll see how it works.

I have a wing at the house waiting to be installed, but I need to get some supports made to get the wing high enough to make a difference.

The plan is for a lexan or aluminum splitter flush with the bottom of the bumper cover with the home depot under that.

Careful on the "high enough" if you run SCCA SM2 the rule is no more than 6" above the roof line or the highest portion of the windshield frame on convertibles. If you are mounting it to the deck lid, you will probably want to add some bracing to keep it stable. I will post some pictures when I get my bracing done.

Yes I will be running SM2.

Looking at a few examples of wind tunnel results, I should be OK with a wing parallel to the roofline. Maybe a little lower will work. Only testing will tell.
