Really? How thick does it have to be to demonstrate an improvement?

Coating may work slightly, but not much. The ****'s too thin to do anything meaningful. If you put 1/2" of the coating on, it would help. But .006" worth ain't ****.

Again, you aren't (nor can you) stop -all- the heat from radiating, only some of it.

Yeah, but how much do you think a .006" coating stops? .03%? Maybe? Negligible.

Com'on, you've got better fallacies to offer than a circular argument, don't you?

If it helps you spool faster, then it will keep you at speed more effectively, right?


If it lowers your under-hood temps more effectively than a heat shield, and extends manifold life, then why not do it to a car that often suffers from an overheat condition in stock form vs. one with a turbo? (Keep in mind, I would suggest doing the manifold, the and the downpipe as well)


Sorry to the OP, I didn't mean to take us so far OT.

Without empirical evidence in either direction, how much water do you believe that argument to hold?

I don't care what the material is, .00X inches of it isn't much. Think about it. Granted I don't have any numbers on ceramic though.

And I'm pretty sure a shield is better than a coating for several reasons.

Feel free to start your own thread on coatings though.

Build:



This heatshield is sprayed with DupliColor DH 1606 High Heat Aluminum paint. It proved to be worthless on downpipes, but holds up very nicely on surfaces that don't actually have exhaust gas coursing directly through them. It yields a nice sort of matte finish that has proven to be reasonably durable.

a blanket is great until your turbine housing sloops; which leaves the shield as the wiener.

While Mr. Perez's shield is pretty, it illustrates what I'm trying to avoid.

I'm thinking it would be better to have a shield that better "wraps" around the entire manifold rather than just building a 3 sided box above, beside, and behind most of it. His still lets air blow right on the manifold toward the #1 cylinder. And if any water dripped down, it could contact the manifold there too.

With mine, (whenever I finish it) it will wrap around the top and sides of the manifold completely, which should better protect the manifold from the elements and, I would think, result in less heat transfer out of the manifold.

To me it seems it's better to shield the hot stuff rather than try to cover up the stuff you want to stay cool. I mean, what keeps the master cylinder from getting hot? Cool air moving by it. So wrapping it up might help keep heat away, but it also keeps cool air away too. Where putting shields on just the parts that get hot will result in less heat period.

Sloops?

Search yields nothing.

I don't know that ceramic coating works here, but it is worth it for aesthetics:

You spent all that money on your car to make it a track machine and you don't have a cold air box for your intake? Seriously man what gives?

And you still have the cruise control operational... along with EGR Canister... and OBD bracket and connection box still in sight.

Beautiful car tho....built right.

Sorry about the thread jack.

Don't get me wrong- I love your idea of the OEM-style full shield. I was posting mine to illustrate the paint I used to cover it.

Ah, gotcha. Yeah, I'm definitely gonna try that on my shield. I searched one of your old threads where you made that shield and I thought it was aluminum till you said it's painted just now.
