I have a 2010 Grand Sport convertible with a stage 2 Edelbrock supercharger that I drive in the Arizona heat. I would like to reduce my under hood temperature and I was wondering if there are any mods to do that. I do NOT want an aftermarket hood or scoops. Any other ideas will be greatly appreciated!

I'd be very curious if someone has an answer to your question considering your handicap. Without scoops (a way to pull fresh air in/out)...this should be interesting.

I can't remember if it was a C6 or not but I read where someone removed the rubber seal at the base of the windshield so the hood has a gap when closed to let heat out.

Perhaps a minor cowl induction? Your options are very limited.

Ceramic coating the exhaust..

Yes you can do this on a C6. It just pulls off, very easy. I did it this summer but did not like how much my hood bounced around in the center. Put it back on. Might just remove it durring the summer heat.

The bottom line is you need to get the heat out of the engine compartment. That being said, you have limited your options to removing the windshield seal or a louvered hood. I would remove the windshield seal first and see how that works. Next may be a hood.

I know this isn't much help but I would be curious to know how much hotter it gets in your engine compartment compared to a non-modified car. More power always means more heat but just how much and/or is it demand related?

About taking the hood rubber trim off. If you were to buy some more of that trim you could cut it into smaller pieces and space them out along the back of the hood. This would stop the hood bouncing and would give you vents so the heat can escape.

What is your engine temps? Have you upgraded to a 160 degree Tstat? Could wrap your exhaust in heat shield. What really matters is what your engine is seeing for temps in terms of cooling and IAT. These are the things that begin robbing power by reducing ignition timing and causing detonation. I have twin turbos and stainless everything underhood yet my IAT's remain under 100 degrees and my engine temp is around 190 degrees even in city driving.

Thanks to all of you. I have done the headers. I have not done the seal and will try that but my understanding is that the area at the base of the windshield is a low pressure area which is more suited to pulling air in and not out. One of the downsides to a blower is that they are "heat pumps" and they create a great deal of heat. This has nothing to do with engine temperatures which stay at 210 or less year around. Power loss is not an issue here. Thanks again!

One of the advantages of the dry sump oil system, I would think it would help with taking some of the heat away from the engine, not to sure it would help greatly with under hood temps though.

what about a simple Camaro ZL1 heat extractor, would allow you to keep your stock hood, but let the heat out.
lots of guys buy them and cut a hole in there stock hood.

Lew Shaw

I had considered that, but have not seen one in person to evaluate whether it would fit above my supercharger. As it is, the hood pad just touches the top of the s/c and it appears that the Camaro unit would protrude below the stock hood bottom. Please let me know if that is correct. Thanks!

Why do you think underhood heat is even an issue? If coolant temps are fine, then all is good. If not, upgrade the radiator/fans/etc.

Lew Shaw

It is an issue to me and that's all that matters. FYI, I already have upgraded the radiator/fans, etc. but those have nothing to do with underhood temperatures.

It might help if we knew exactly what the issue your having is then. Are you having issues with wires melting? Is there failure of electrical components due to elevated temperatures? Are custom painted parts showing heat related wear? If none of the above and your coolant temps and IATs are in check without any loss of power (your words) then it sounds like things are ok. Engine bays get hot. Even more so with a blower. It's just a natural byproduct of the internal combustion process.

Unreal

Everything under the hood is made to run hot. So making up issues doesn't get you very far. What are you trying to fix?

Lew Shaw

Looks like I have received all the useful responses that I will get.
Thanks to everyone!

Thought I seen a post in past about installing a big capacity rad eg DeWitt to reduce over temps. Not sure this is would help.
