C7 style heat extractor
I know this topic is probably gonna get me kicked around a bit, but I was wondering if anyone has tried or thought about trying to build a heat extractor setup similar to the c7... with the enclosure on the rear of the radiator funneling hot air up and out through an extractor hood... it can't be all that hard to make one out of fiberglass and test fit it... thinking I might try to do this and see how it goes..

the hood has been made-ish, one guy made his own by glassing the C7 vent into a C5 hood but I haven't seen a funnel for the radiator & hood yet

there are heat extracting hood out there on the market now... the under hood pressure makes the heat extracting hood work... the heat exchange is the product of sucking air through the condenser and radiator. no need for plumbing.. heat rises and the proper placement of an exhaust vent ( and not at the base of the windshield or cowl rear of the hood. Evidenced in wind tunnel testing.. the placement of the heat extracting vent it properly placed where testing has been done.
This is a properly placed C5 heat extracting vent . with under hood pressure and this vent, it extracts high volumes of lighter weight heated air. you want the whole engine bay to benefit from heat extraction not just the radiator and condenser.

The member that grafted in a C7 hood vent to his stock C5 hood was dreamscometrue. It looks very good IMO.

Its a MCM hood... adding open front scoops to bring in cold air under a slight pressure, pushing cold air into the engine bay and hot lighter air is forced upward and out the vent.
the fog light surrounds are removed and just some screen to keep out trash. Very effective to get cold air into the engine bay and increase under hood pressure to force hot air out.

a Vararam is used for the engine to introduce cold dense ( more volume by closer air molecules) into the throttle body, it does nothing to reduce engine bay heat. Vararam is about the best CAI system out there.

I know. I only mentioned it because it blocks off the scoops in the nose from pulling any cool air to the radiator

One other thought... would there be any benefit to creating ducts that go from the engine bay to the side vents in the fenders? Removing the sealed plastics of course, and blocking off and water from getting to the PCM...

this is by far the best looking aftermarket hood for these cars IMO.For what it's worth, the above pics of a cut in grill look awful IMO, they destroy the beautiful lines of the C5 factory hood. It just doesn't flow with the smooth/curvy c5 lines. (I'm not talking about the workmanship, that looks fine)

Not sure if Marc at Vettenuts will ever get the real MCM hood into production. He has all the original equipment, the problem is, they are time consuming to make and not conducive to making a profit. I am fairly sure that is where Marc is on these... Even at the 2001 price of 1200 dollars + shipping. He would make no money in todays economy. with the cost of real carbon fiber, labor, and the time that it takes to make a single hood Marc would need to sell them at 1500 to 1800 to make a profit or to make it worth while to make them at all.
The original MCM were made with love and passion , not to make any real money. Last update from him was trying to find someone to build them for him. Marc doesn't have the time to invest. I don't think the market will handle the retail price need to make a profit.
