I also have the Cervini Mach 1 hood on my car. That should let some cold air in and filter the hot stuff out the cowl in the back.
The air flow won't work that way at speed on track. The cowl isn't a low pressure area at speed, so warm air won't be coming out
, instead you'll be pushing air in
. (Hence the term cowl induction
Obviously at low speeds you'll vent warm air out there - you've probably seen it while you're stopped. I've never seen anyone do some yarn tuft testing to figure out at what speed a cowl induction hood starts to push air into the engine bay rather than letting air vent out. Considering how relatively vertical a Fox's windshield is (compared to more aerodynamic modern cars), I'm guessing the transition is at pretty low speed.
