David Stroud IM Roadster D posted:FWIW, I placed my aftermarket heater core in that cavity behind the rear seat bulkhead / ahead of the engine firewall and the two hot air outlets from the core were routed via aircraft scat hose to the door rear bulkheads on either side of the car.
With or without coolant flow to the heater, there was always a slight flow of air into the car through those hoses without any heater fan turned on. With the fan turned on to speeds 1, 2 or 3 there was no shortage of air flow. Evidence of high pressure in that cavity ?
Hard to know, right? It is all relative from one area to another, and how the heck do you know without doing extensive tests, which would be way too cost vs reward prohibitive? The funny thing about the coupes is that they look exactly like a backwards airfoil/wing.
Just did something kinda nutty. I emailed Emory Motorsports and asked if they know of any reference material on 356 aerodynamics. Can't hurt, right?
