Hey guys I'm determined to get my engine bay temps down but am wondering what you have? I have a friend with an RX-7 that recommended I install some heat shielding like he has. He referred me to these guys.

I know RX-7's have to deal with huge amounts of heat and my buddy says the inconel shields are a day and night difference and he actually gained power!? Apparently you can send them any part and can custom make one off shields, what do ya think?

 

I just got Jet Hot thermal coatings on my exhaust housing and downpipes; it might be a cheaper and equally effective method to keep engine temps down.

Also, those exhaust heat shields seem really expensive IMO…

 

thats reallly expensive, i remember turbo blankets were around $100.

 

Im thinkin bout turbo blankets... was wondering if anyones got a link to actual results of AIT being reduced n by how much? Everything is already installed on the car n i dont wanna be a PITA to someone to take it all off n coat all the piping n put it back on if it aint gonna yield some pretty good results... turbo blanket is about as far as i'd go prolly

 

If everything is already installed, I would add the turbo blankets and heat wrap the downpipes. Doing that reduced my engine bay temps quite a bit on my last build.

 

Thanks, the turbo blanket is definetely on my list to do... gonna try heat wrapping DP's as well

 

To help reduce the under hood temps I did the following:

Ceramic coat
turbo hot sides
turbo manis
down pipes
all cooling system hard pipes

to reduce AIT
i ceramic coated all air pipes that run near the manifolds, the inside of the intake pipe that goes to the throttle body and the lower intake collector.

My under hood almost gave me a heat stroke when i opened the hood it is much better now. If your car i apart it is a good time to ceramic coat things, it is costly but if heat is a problem there are limited options.

 

Vented hood?

 

Compared to the cost of ceramic coating, wouldn't heat wrapping be a cost effective solution for lowering heat temps?

 

It works but not as good, it is also rumored that heat wrapping the turbo can cause premature turbo failure due to trapping the heat in the turbo. But it is a cheaper way or reducing temps.

 

Ceramic coating the downpipes isn't all that expensive. The company I use here in So. Fla., Fuzion Performance Coatings, charged me $150 for both last time around.

I have been told by some people that ceramic coating is more affective than heat wrap, but others disagree. I have not seen any data comparing the two. Nonetheless, ceramic coating certainly is the cleaner way to go. Then again, it's hard do see the heat wrap unless you have your car on a lift.

 

so heat wrapping or turbo blanket can possibly lead to turbo failure? That sucks

 

with the motor out, what all can/should be coated? what would be a waste?

 

Manifold, exhaust housings, downpipes are what I would do.

 

I agree those are the important ones. Anything after that if likely overkill.

 

even after ceramic coating, the heat wrap seems to emit less heat. i had 1 DP wrapped and the other not and it was pretty obvious.

just nervous about wrapping the headers though, waiting for word back from SFR about that.

 

Even though they're stickers, they work wonders. It's science.

Just kidding, but good luck with the issue.

 

It's no rumor.....it happened to one... of my.........Haayyyyy... Are you are talking about me Gord??!

 

heat wrapping is FAR FAR more effective then ceramic coating. its not even close comparison guys!

you can momentarily touch headers that are heat wrapped straight out of a dyno run! try that with ceramic coated manifolds and your gonna melt your fingers to it.

my first greddy setup was all ceramic coated. i didnt bother this time around. just the heat wrap.

BEWARE, heat wrap will accelerate cracking of the manifolds and downpipes.

get a vented hood. remove extra crap that heat soaks. heat wrap the hot parts. with my new intake manifold and piping setup the intake manifold is ICE cold when i park after driving in the evening. McLovin it.

 

Heat wrap is more effective at reducing heat but can cause premature failures = ceramic coat > heat wrap IMO!
