Topic: Heat coatings question

Hi everyone so in our car we suffer from insanely high interior temps during the race. There is no  insulation of any sort under or in the car so it gets quite toasty inside. I run my cool suit in October at the new Hampshire race and still get out of the car pouring sweat. We are looking into getting Lizard Skin coating to apply to the car. However I would like to try and get some opinions on the matter first. If anyone has done this or any other style of heat coating please chime in. Thanks for your help/ input

Re: Heat coatings question

Q: What kind of car do you have where the engine is bleeding this kind of heat into the passenger compartment? Something mid engined?

Re: Heat coatings question

We have a Datsun 280z. The manifold is on the driver side and the exhaust runs in the driveshaft tunnel right next to/ under the seat. Its much warmer than any of the other cars I have raced. Granted I do longer stints in the Datsun but its significantly hotter at the same stint time.

Exhaust wrap......
(and install a vent scoop)

Re: Heat coatings question

Put a heat shield between the exhaust and the bottom of the car. The OEMs do this and it seems to work for them. You could add some type of insulation between the heat shied and the floor. Thin layers of fiberglass will work.

^ This.  Don't crush the insulation.

Re: Heat coatings question

My SHO had the exhaust running down the tunnel. I grabbed a good sized aluminum heat shield from a 2001+ Volvo V70XC.
I added that under the car, from the firewall to as far back as it would reach. Leave and air gap between the shield and the floor.
That really helped control the heat.  Added to that was exhaust wrap.

You want to keep the heat from getting to the floor in the first place.
I think coating would be the last option.
Once the heat heats a solid surface, coated or not, connected to the passenger compartment it's going to get in.

Re: Heat coatings question

I've had good results with coatings to control exhaust heat. Tech Line Black Satin has worked well on several cars. Just do good surface prep (sandblast with something pretty coarse) and use a cheap HF throw-away spray gun because that stuff is a mess to clean up.

Everybody grab your brooms, it's shenanigans!

Let me expand......

Heat shields will help, but depending on the shield they do more to fight radiant heating.  Fast moving air over the exhaust system and onto the firewall and tunnel will transfer a good amount of heat. A wrap will keep the heat in the exhaust system and away from the car. Once down the tunnel even a little, there is less surface area for heat to make contact.

Performance gains too????


And as mentioned, you can install a vent scoop to get air into the car.

Re: Heat coatings question

You might be able to make an argument that you bought this stuff for driver comfort and not the 23423432HP they add.
I had to wrap my manifolds to deal with a (lack of) hot start issue. Wrapping the headers took enough heat away from the starter that I dont' seem to have this issue anymore.

I bought some of this stuff from a different retailer (Coaler Systems) and it was 1/2 the price of the DEI titanium stuff. It worked just fine.
This price seems to be ~half the price that I paid so ti's probably worth rolling the dice on

The stuff you want to avoid is the white/tan coated fiberglass stuff that you have to wet before applying and then seal with silicone spray. That stuff breaks down and is a lot itchier to deal with.
