To wrap with gold heat reflective tape or not to wrap?

[B5S4Driver]

About to install a HFS-3 system. Want to know if i should wrap the bipipe while its out, as well as my CAI pipe
also put a gold sheet on my aluminum heat shield.

I heard they are fakes out there, where do you guys get your wrap?

Thanks.

[Jibby]

Yes, do it. Even the fake stuff still reflects 80% as opposed to the 90-95% of the real stuff. DEI makes the cheaper but still effective material, the real material is hundreds of dollars per foot. I have my y-pipe and bi-pipe rapped as well as the sides of my intercoolers facing the radiator. The silver stuff also works if you do not want the blingy gold.

at the bottom of that web page compares "real stuff" to "fake stuff" and shows that the fake stuff can catch fire...

Just checked out DEI. I'm convinced... I was doing some research, that happened to be the the first website I looked at ^^ annnnnnd at the time I thought I might want to buy from ebay or amazon :headbang:

I am doing the same thing when I install my meth system. I am going to try to wrap my bipipes, intake pipe and maybe inlets too if I can reach them easily. There are fakes out there as you already saw... which sucks cause they are super cheap!

Where do you guys buy this stuff at? Any links?

Jegs or Summit Racing sell them in various shapes and lengths.

since i am on a roll of resurrecting necro threads lately ..
Has any one still use these products ? and which brand?
Has any one wrapped K03 or k04 inlets .. the ones that are right next to the exhaust manifold? I think those would be the ones to benefit more since the heat source is right next to them!
Has any one caught fire ?

Yes people still used gold reflective tape all.the time. People also.wrap.inlets quite often. No they will.not.catch fire.

If.you want to reduce heat the most.effective way is ceramic coating, then wrapping with gold reflective and.finally titanium exhaust wrap. Works flawlessly

yes i have wrapped my downpipes with titanium wrap now am thinking to wrap the charge pipes in gold reflective tape.
which brand? DEI, Jegs?

Reflective tape is useless to stop radiation heat unless you can create a dead air layer between the tape and some other surface. That's how the radiant heat barrier works. If you simply wrap something with this tape and it is in direct contact with any surface, it will have very little effect if any.

http://www.radiantbarrier.com/physics-of-foil.htm

"When a reflective surface of a material is attached to a ceiling, floor or wall, that particular surface ceases to have radiant insulation value at the points in contact." - that's wrapping your pipes in foil...

You'd be much better off using traditional fiberglass wrap. Spray it generously with high temp paint (I chose silver) and wrap piggies/downpipes, turbos etc. Mine are done this way for quite a few years now. There is zero chaffing (since paint holds it togther well) and a can touch turbo's/piggies with bare hand and not get burned so it works. For intake pieces, use aluminum tape with fiberglass instead of pure reflective tape. That at least has some reflective value since fiberglass is poor heat conductor and it doesn't rob aluminum from all its reflectivity.

i dont think anyone is implying to wrap parts that produce heat with gold reflective material! That would be a no no since it would destroy the material in minutes! Wrapping charge pipes that are NOT in direct contact with heat source (exhaust manifold) but are near the manifold would benefit since it would give some level of reflection. The only two things that puzzle me is that.. this type of reflective material protects from light heat (solar) and not thermal ? 2nd since aluminum retains heat faster but also dissipates heats fast .. would the gold reflective material play a negative role in dissipating heat?

Reflective material ceases to work when in contact with the heat source because the heat is then transferred through conduction. There is "dead space" between the heat source (engine, exhaust manis, turbos, etc) and the material you want to keep heat from entering (inlets, bipipes, intake, etc). Therefore if a material has say 90% thermal reflectivity, it will reflect 90% of the heat away from whatever it is covering, touching or not.

I'm not sure of the other properties of that tape, but if you wanted to further reduce heat transfer to the inlets or anything, you could wrap or spray with a insulating material first. Or use aluminum fiberglass tape like you mention, but I see the reflectivity of the gold heat wrap stuff as a greater benefit.

I did this a while ago. I don't recall the specific outcome, but the fact I can't tells me it probably did very little.

during my 1.8t days i had built a heat shield/box from home depo aluminum. The temperatures had dropped a bit but still not what i wanted. then i added some silver reflecting really cheapp one but it was a little thicker then these tapes . When i was logging with vag com 4 out of 5 times i would see even lower temperatures .yes the shield was thicker but the temps were 3-5 deg lower
