we all know the valve covers get so hot that you can burn your hand on it. that is if you have a defective nervous system that you dont pull off by reaction. its also contributes to the engine bay heat which will also contribute to power loss with the use of a hot air intake.

would it be a good idea to use the same coating on headers for the valve cover? itll help seal the heat in the head and out of the engine bay. it might even make the exhaust air hotter and increase exit velocity.

not only will it be functional, it can look stylish as well.

 

I don't think that's a stupid question at all.

One thing I suspect, though, is that trapping more heat under the cam cover wouldn't be good for the oil. I may be wrong on this, but it seems to me that letting that heat escape might be better in the long run.

 

yeah im not sure on the effect on the oil if any. i guess a good catch can setup can help it.

anybody experience with trapping more heat in the engine?

 

ok if you are actually conserned about the air that your intake sucks in..
there's not really a temp differance while the car's moving.
if you are STILL worried about the heat in your engine bay
get the header wrapped, CAI, hondata type of IM gasket AND paint your valve cover which i dought it will make enough temp differance for you to feel the lose of power OR the gain from this.

and painting the valve cover with other paint..will actually make internal temperature differance?. i dont think those high heat exhaust paint are supposed to trap any heat VS the oem red valve cover.

and if somehow there is a way to trap all the heat IN the head/block..oviously it's not gonna be good for the motor? cuz it will run Hotter?

Not necessarily true.

Heat is nothing more than wasted energy. The more heat escapes your engine, the more energy is wasted. The trick is keeping the heat/energy in the combustion chambers. Heat in the camboxes or crankcase are not generally considered good.

 

My valve cover never gets that hot that you cant leave your hand on it for a while...its possibly the coolest part of the engine (when the engine is hot)

I can say that my valve cover is about as hot as my oil is. So, basically, hot.

 

Saw your other post a few days about the intake wrap, I'm curious to know why are you so worried about your engine bay temp?

 

im using a short ram intake. trying to get as cool as possible.

Don't do it, your not going to see anything from it...

And honestly for the hassle it would be why not just work a few more hours and spend some money on performance upgrades.....

 

Yes... stupid idea.

 

how about getting an icebox if you're concerned about heatsoak?

and an outlaw engineering gasket kit?

Problem elegantly solved.

I've noticed using an aftermarket, especially ceramic or coated header will make the engine bay cooler than with the stock header. Not sure if there are any decent ceramic headers available for ITR applications though. Also, have you considered upgrading to a Fluidyne radiator?

 

Oh, I misunderstood your reason for wanting to do this.

If you're just trying to avoid heating up your intake charge, this won't be very effective. There are far greater sources of heat to concentrate on.
