Reflective blocks radiation heat from the sun UV etc. it reflects so it bounces off. An engine bay puts out convection heat not radiation. I wrapped my intake and the heatsheild in the fiber wrap they use for headers. On a Supercharged Audi A6 I saw a consistent 10 degree difference.

I don’t get how that makes sense, header wrap is meant to keep heat IN not out, so you’d think that any heat you accumulated inside your intake tube wouldn’t be able to escape since you wrapped it using header wrap

Heat coming off of the engine is emitted via infrared radiation. The sun emits both Ultraviolet and Infrared radiation. All forms of energy are on different parts of the electromagnetic spectrum.

@pqmodean6 ай бұрын
My intake in my Altima is right over the upper radiator hose. I wrapped the intake and using the torque app i noticed a drop in intake air temp by 10° alone. While in traffic it gets as high as 140° but cools down a lot faster than with no wrap. It would get to between 15-20° above what the air temp reads at the dash in normal driving. Highway driving at 65-70 it gets just over 10° of the air temp. Then i thought what if i also insulated the upper rad hose. So i used the bubble wrap the tape came in and lowered the temps 10° lower in normal traffic and to within 5° at highway speeds. I ended up insulating the rest of the intake with a silver bubble style windshield sunshade. Next i plan to do the air box itself in 1/4” foam deadener then gold foil wrapping it.

I think we also need to take into account the potential error of using the gaff tape. Gaff tape is a thicker, cloth style, tape that could potentially be creating some sort of insulation (unless you put the gold foil over the gaff tape, but if you took it off then that could be the error).

The best way to put it on is is not to continually wrap it around. Cut one piece that is big enough to go around intake tube circumference, then cut another piece and do the same thing repeatedly slightly over lapping tell wrapped.. the tape likes to go on straight and it does not like to wrap around like a ace bandage!!!

IAT also gets influenced by heat soak through the intake manifold. Likewise the intake tube can suffer from the same heat soak. If we can battle this heat soak as much as possible before the intake manifold, intake air temps will be low but you have to remember the heat soak starts at the engine. Even though the velocity of the air is high moving through the intake system it is still absorbing the heat (think heatsink).
@thecarizon5045 жыл бұрын
Heat soak to the intake manifold is prinarely through conduction though as it's mounted to the block. Wrapping the intake manifold doesn't protect against this. The intake manifold's proximity to the block does however make it a better candidate for IR absorption but it wouldn't be possible for me to practically measure the intake temperatures at the cylinder head.
@onefastneonrt5 жыл бұрын
@@thecarizon504 absolutely correct but heat soak through the manifold could be buffered via a composite spacer. Wrapping of the intake manifold will not show any improvement. Isolation of any heat soak through the intake piping is more so what I am talking about. I'd be more curious to see if you could isolate the IAT sensor from heat soak and see what the gain would be.

Wow. What a flawed experiment. Reason temps with gold wrap were hotter is that the foil tape conducts heat much better than the black plastic tape. Yes, gold reflects IR radiation better than any other material, but once the engine heat reached a certain temperature, the foil’s ability to reflect the radiation was overpowered by the foil’s tendency to conduct heat across its surface. You needed a layer of insulation between the gold foil tape and the intake tube to make it work.
