Roadster heat problems?
What with the new hood vent taking engine heat over the top of the car rather than under the car as in the C6... will the top-down driving experience include a very warm back-wash in the cabin?

Shouldn't be a real problem as the air coming out the hood vent only passed through the radiator and the engine compartment is separated and will vent under the car and possibly some through the side fender vents.

This, and much of the heat should be dissipated by the time it gets over the windshield.

I'm not real worried.On cold days that would be a good thing if it did happen that way. On warm days you could always turn on the AC if necessary.

Actually the design of the aerodynamics, according to the C7 design gurus, is that the air exiting through the hood vent is routed around the sides of the car. This is true for both coupe and convertible. So perhaps there will be slightly warmer air passing by the side windows, or window openings.
Ferrari, McClaren, Viper and others are all now using the lay forward radiators and hood vent design - track derived technology brought to the street

I also understand that only some but not all of the air flow is sent through the radiator. The rest has a clean path out the hood. In looking at photos of the engine and the duct, I wonder if the duct even see's any of the radiator air.
Looking at this photo of the engine compartment and the angle of the duct:
This photo of the frame, you can see the radiator rack.
I can't help but wonder if the air that flows through the radiator is exhausted out below the car or into the engine compartment and then through the side ducts instead of out the hood.

The air directed through the top forward leaning radiator exhausts through the hood vent - engine compartment heat is exhausted elsewhere

In the 2014 Corvette, the air passing through the radiator is channeled quickly up through the opening in the front portion of the hood. This prevents that hot air from gathering around the engine so the heat is removed more effectively. Also, the turbulence created by the cooling air “trapped” in the engine bay can cause front end lift while the cooling system of the 2014 Corvette actually provides better downforce at higher speeds."

I live in Tucson and it gets pretty warm here in the summer and I never have had a problem with excessive heat in the console. Are the people that are having problems with that running headers are some after market exhaust system?
My car is totally stock and it just never gets too hot in my car's console even in mid summer with the top down.

The C7 Design Gurus has said that they are employing an insulating material in the tunnel to address the heat issue. I do not have the technical info - perhaps another member can refer us to it

I have always been a little surprised when people post about how excessively hot their console gets.

Much ado about nothing, or some overly sensitive people driving Corvettes.
