Default Underhood temps

Ok, so as you can see from my mod list I have aftermarket headers. They are coated but my under hood temps are getting so hot that plastic pieces are starting to get brittle. I mean so hot under there I can feel the heat radiating through the firewall. I was thinking about buying another stock style hood and putting some heat etractor vents in it. Problem being I dont want it to turn out how do I put it elegantly...Rice I guess. I would like it to look sporty but not ricey and look almost stock. Any suggestions?

Aww damn, I forgot he had a TA. Have you seen the LS1 TA Raptor hood with heat extractors before? If you did it I'd imagine something like that would be the best looking way to do it.

Kind of, Im just not sure how much I like them. Plus Im on a budget right now, Last I checked them hoods are expensive as hell. But I will keep the idea open as an option

I was driving around for an hour and a 1/2 last week in 90 degree weather and I also felt that damn heat through the firewall and tunnel. My right foot was getting damn hot.

I have a ws6 hood (partially blocked openings though), and I'm not sure if it's helping alot.

One thing that comes immediately to mind that you can do and is cheap is put some washers on the hood/hinges to prop up the rear like back in the day. Either, heat rises up and over the windshield, or some of the wind will crash the windshield and travel down the engine bay compartment.

WIth our windshields being so raked, it's probably not the second one.

As good of an Idea as this sounds and I am sure it would be pretty effective if done right. I really do not want to add more electrical fans to my car. I plan of Turbo Charging my car soon and I already need to free up some of my engine bay.

I think all of us with headers experience the same problem with the firewall.

Header wrap is the DEVIL!

Thank you, I was going to say just that. Header Wrap is not good for daily driving. I only drive my car during the summer and still dont put many miles on her. But Im not going to risk using Header Wrap.

It help if you not daily drive, but with daily drive it will rust to hell and you dont even know it rust or leak under that wrap, I would stay away from it. A friends spray a coat of temperture reduce can thing and it reduce the heat alot. im thinking do that to mine.

I've been thinking of removing the rubber bulb seal between the windshield cowl and the aft edge of the hood to let hot air out. Allthough that may be a high pressure area so maybe cool air would be drawn into the engine compartment.

What would be cool, is if you had an Electronic solenoid that would open and close with either the start of the engine or at WOT Like the old school Shaker Kits to let the heat out. But any ways guys, I have to jet to the gym or else I dont get paid (What little I make any ways)

That is what has kept me from removing the bulb seal, although the guy with the Z28 who opened up his scoops is going to get rain thru them.

Read the whole thread, it's not a problem, and the benefits are worth it.
