Um...that car does not have the LT4 SC motor. And the vents are likely there in large measure to reduce lift in the front end. They have nothing to do with "..this car..", meaning the C7Z06.

Jeremy,

Are they running a supercharger or turbo(s) on that C7R?

No blower cover or shroud on the Z06. The only hood vent is the partial exit for radiator airflow. Wonder if propping the hood open ~ an inch or so would help engine compartment cooling without a great impact on aero? You could seal the radiator to hood vent gap with a piece of foam.
That would be a cheap way to see if there would be any gain from installing vents in the hood.

Nice.....thank you.....good info!

Its all motor.

Nice to see this thread get back on track and evolve into a productive discussion instead of the usual chest pounding and name calling. Lots of good info here that is very informative.

Thanks all.

Good idea, doesn't TIKT or whatever they're called sell those hood brackets that allow it to latch while being an inch or two open? They do for the C6, at least. Heck, some washers and two bolts will work for mechanically inclined people to do it themselves. I bet it would help vent some excess engine heat for sure and it would be cheap to try out. That, plus the distilled water/water wetter in the radiator for hot weather guys instead of the factory coolant will be the two easiest/cheapest/best cooling options likely available without going aftermarket.

I still need to swap out my radiator fluid for distilled water/water wetter. I live in TX and won't ever drive the car when it's cold out, so should be good for me and it is supposed to help noticeably with the heat dissipating ability of the cooling system.

That looks like a GT1 or Trans Am car. I did not know privateers could even obtain C7Rs

And if indeed it is a Trans Am car, it is probably more like 2500 pounds and tube frame, with a normally aspirated engine. I'm afraid it probably has no relevance at all to the C7Z06

my friend has 2 of them. They are quite a few out there now. He placed 4th at daytona. But feels the car is indeed a winner this year. And this is coming from a guy that has raced Porsche's for years.

kverges

If he is running Trans Am there are no Porsches. Exactly what class and series is this car running?

rikhek

Yeah, that was one of tide them thar rhetorical questions. Makes my point that race cars aren't FI unless forced to do so like F1.

A good analogy specific to the C7Z as a track car is like new track guys looking for an alignment or brake pads or tires that work well on street and track. This unicorn does not exist.

kverges

An incorrect statement on forced induction. Some of the winningest cars in endurance racing have turbos. 956. 962. All the recent Audi LeMans entries. Even the old Auto Union cars.

Perhaps the mightiest road racer ever to come to US was the Porsche 917/30. There were no rules restricting power plants and displacement in Can Am in the early 70s. The 917/30 CRUSHED the big block chevy powered cars.

This was the news release from this past daytona event with the corvette.

looks like I will be running road atlanta this saturday. Got a invite from my friends over at MTI racing. Anyone else interested go to http://tracksunlimited.net/

Hope to see some of you out there. 49* and partly cloudy.

kverges

Unless I am mistaken, this confirms that it is a Trans Am car, not a C7R. Addition, and ask your friend for confirmation, but I suspect this car shares not a single component in common with the C7, let alone the C7 Z06. It's a tube-frame, purpose built race car with a silhouette fiberglass body. Cool car, to be sure, but does not teach us much about the street C7 Z06

DonLakeFlyer

Seems like there are quite a few folks who have tracked there cars here. If you have tracked your car at more than one track and have a PDR can you take a look at this: https://www.corvetteforum.com/forums...rt-marker.html

Corvette Forum has asked Tadge Juechter about the C7 Z06's tendency to overheat after a bit of flogging. See Juechter's answer after the jump.

Great Pic!

It's not just F1. All of the high end LeMans prototype cars are turbocharged, including the newest entry by Nissan. And for road cars, you have turbos on the new Ferrari 488, all the McLarens, the GT-R, the upcoming Ford GT and NSX, the new Mercedes AMG GT, and the rumour is that all future Porsches will be turbocharged, not to mention the new super hybrid cars and BMW's and other Mercedes cars, etc.

If the Chevrolet design staff had thought things out properly, they would have left room in the engine compartment for a twin-turbo V8, and we wouldn't be having all this talk about supercharger issues for a track car.

thebishman

Claude, the car, (certainly in Z07 guise), has the brakes, suspension, etc. to be a fantastic performer for a street vehicle on the track. The (potential) overheating issue seems to be the only concern, and IMHO it will be much easier to address that than it was for us GT-R owners back in '09.
