ie; Vacuum it out via the A-pillars!?
The idea here is to kill 2 birds with 1 stone:
Minimise the amount of hot engine compartment air that normally exhausts out under the car
and
Decrease the lift/vacuum and preferably the drag that exists at the front, top of every car roof.
If you have been looking for ways to minimise the flow of hot engine compartment air out underneath the car, you might put some thought into the idea..? |
A look at Professor Alberto Morelli's 1978 CNR P-F concept illustrates one of the most 'scientific' cooling systems ever investigated.
All outlets were wind tunnel tuned at Pininfarina to introduce the engine bay air into their respective boundary layers at exactly the same velocity, so as not to introduce pressure spikes. They spent over $100,000 in tunnel time to dial them in. That would be $400,000 in today's Dollars.
