This is a REAL cowl induction hood (the part flipped up is where the air enters...the end of the hood is open to the engine bay to extract heat)

I'm tired of seeing them on a ford or dodge! YOU race in Ohio any? Late models kick ***!!!

Quote from Keystone's website....
I HAVE spent some time researching this in the last few days as well.....and we're BOTH right actually, but it depends upon the design of the cown scoop as to whether it works better for extracting head or for channeling cool air into the intake tract. the functionality of the cowl is completely dependant upon the design profile and shape of the cowl scoop...if it's shaped wrong for the application it will do more harm then good apparantly. I appologize for NOT knowing this BEFORE I posted....
'Nuff said I guess.....
The cowl induction hood is not a new idea and it actually works. That's why NASCAR uses them in their Winston Cup Cars. As the air passes over the opening, it creates a vacuum of cold air over the windshield. This allows the hot air from inside the engine compartment to escape letting the engine breathe cooler air and therefore running stronger and longer

Interesting reply fellas. Due to the design of the Reflexxion Cowl hood, I believe it was designed for future induction purposes, not for heat extraction. If it was for heat extraction there would not be a seperate compartment built into the hood leading from the cowl(windshield) to the front right of the motor.
In any case, it looks like I will have to design my own system if I go that route.
