It would be interesting to see the same tests run on a non-Nismo 370Z. However, C&D chose not to do that and you can't compare these tests from two different days and draw a conclusion on whether it's specifically the Nismo fascia, or the general design of the 370Z.

There are two primary issues: cold air entering the wheel well, and hot air exiting the wheel well. You can use front-mounted ducts to push and it, and have the rotor create a vortex to push air through the veins. From there you can have a slotted fender to create negative pressure and suck air out of the wheel well.

It's odd that the fascia would be so efficiently designed to push air past the wheel well entirely. I mean even if that were the case air moving past the wheel well would create suction within the wheel well, and should pull in air... maybe the chin spoiler on the Nismo front fascia is too restrictive and isn't allowing air to come in from underneath the car? I don't know if the issue is simply exiting hot air or that it doesn't have enough fresh air.

Then again, I haven't taken a physics class in a long time and should get back to work.
