How flexible is the aluminum stuff? Does the gold foil have any foam or some kind of separator? Without a separator it is just adding density to whatever you stick it to, which will result in it maintaining its temperature longer whether it's hot or cool, which makes sense with your results. As opposed to actually blocking the heat.

the aluminum shield is pretty flexible. The gold foil has no separator but it has the technology to reflect the heat.

It's purpose is to lower the panel's emissivity, which will reduce the radiative transfer of heat. However, the shiny silver heat shield has a very low emissivity to begin with, so it's not going to make much of a difference. Now if the heat shield was matte black, things would be different.

In fact, in my opinion, based on successes in the past with this, better results than the gold and all is possible with just black paint... Rustoleum BBQ Black High Temp. This is what I, and everyone else who cared, used to coat intake manifolds on big blocks, for example. You can't do much about heatsoak due to most influences, but you can influence emissivity.

In fact, putting reflective material ON the TMIC probably reduces its effectiveness.

do you have any real data showing that your rustoleum spray paint out performs reflect a gold foil tape? reeeeeaallllyyyyy skeptical about this claim. Ive actually used this before on exhaust of a 1996 honda civic hatchback. Now that d16 engine had a close coupled cat than the first exhaust piece all the way back was painted. That stuff doesnt last and flaked off because of the heat of the 96 hp engine. I still may have a partial can in my garage still.

It all depends on whether the part in question is hotter than the surrounding parts or cooler than the surrounding parts, and what direction you want the heat to go.

I was thinking about this as well; gold foil on the bottom of the hot side end tank would probably suffice. Blanketing it fully seems counter productive when the turbo is cranking hot air into it. But, the IC seems to be able to keep up just fine though with whatever additional heat that might be.

This is all good and all, but could you post the ambient temp during testing also?

68F in a climate controlled setting.

It shouldnt even be a close comparison. Black is the worst color for a heat treatment designed to reduce radiative heat. Black naturally has the highest emissivity, white would be a much better choice if you were to paint. But honestly nothing really comes close to the gold foil for low emissivity.

Anyone have any thoughts or experience with a ceramic coated heatshield with gold foil on the inside?

It becomes very addicting removing as much heat as I can now that I can actually see how effective these products work

Have you looked into extracting heat from the engine bay? I'm thinking hood vents, front fender side vents, and front fender top vents(like S206) as well as front bumper side vents. Might be tricky to take pics of these as they work best at speed but might still be possible to see those in action with radiator fans on. I'm thinking with all the other cooling mods you have implemented those might have a good additive effect.

Thank you for doing the research in heat management in the engine bay. I have always been curious as to how well the different products worked.

This would be a very challenging test to complete as you have stated that they are designed to work while the car is in motion.

I've been seeing a lot of new faces around here with new cars the past few weeks. The thermal questions are starting up again and I encourage you all to research before you buy and ask as many questions as you can. Ill bump this thread and please contact me if you have any questions.
