Wrap intake tube with what?

So I want to create a thermal barrier for my intake tube that passes behind the engine to the turbo. Should I use reflective wrap or something more like header wrap? In my mind I see the reflective wrap reflecting heat (duh), but on the other hand the header wrap designed to keep heat in might also prevent heat from getting in from the exh manifold.

Maybe even some foil tape for ducting as a low cost solution?

edit: oe plastic tube

Can you get the Velcro hose wrap in a big enough size? That would make for a real clean look.

Heat sleeve, that's the term I was thinking of. So far I only see up to 1" but I thought I saw larger stuff.

DEI Gold Foil
2015 Ford Fiesta ST Engine Compartment with DEI Gold Foil by Bryan Redeker BRGT350, on Flickr

2015 Fiesta ST gold wrapped induction tube by Bryan Redeker BRGT350, on Flickr

I wrapped sections of the upper and lower airbox, induction tube going to the turbo, and the cold charge tube from the intercooler to the throttle body. Since the picture was taken, I added the Mountune induction tube to replace the factory one, which has better thermal properties. On my brother's 1.0L Fiesta, we wrapped more of the airbox and all the tubing going from the airbox to the turbo. The turbo sits high and up front, so heat is even more of a problem. For extra heat resistance, I wrapped a number of sections with thick aluminum foil tape and then layered gold foil tape over it.

These are some good options, I do like the velcro wrap stuff.

BRGT350 any logs showing an improved of small but any?

Sadly, I don't have any data logs. I started the installation before I got the Accessport. I took about a month or so of doing little sections at a time with the wrap and did it in the fall as the temps were dropping quickly outside. I doubt I have driven the car with the current amount of wrap in temps warmer than 60'F. I wanted to get the tape installed while the engine was clean and before winter since everything is covered in salt/sand/dust/mud and the rest of the crap that coats the car in the winter.

On my DIY 3" aluminum intake I used some aluminum foil, fiberglass later under it but very thin, it helps quite a bit but not measured for effectiveness, I think it was a DEI product but long since lost the packaging.

When I build or adapt this one for the EFR turbo install I am going to use some thicker fiberglass with thicker aluminum over it but it will have to be cut into sections for the bends so I will add a wrap of silver heat tape over it.

The gold foil works better than aluminum but costs a great deal more and if only a single layer thick will not be as effective as the 1/8" fiberglass and aluminum covering I will use. I just do not want the gold look either but have consider it, more than once.

-------

I have also heat wrapped or slide on and some velcro type on hoses, IC to throttle body tube, shifter cables, brake lines, steering rack, etc........

Decisions, decisions, this stuff isn't cheap for what it is.

Not to short sell the Mfg but if you source the part number or name and check eBay you can get deals sometimes.

I got the gold foil from Amazon as I found they had the best prices. I do want to wrap the fuel lines with insulation and gold foil. Anything to keep air and fuel cooler is a good thing.

On my Mustang, I have wrapped all the fuel lines with fire sleeve and then an aluminum sleeve over the top of that for any sections that are near the engine or exhaust. The air filter sits in a hood scoop, so not much I can do with that right now for heat protection. I want to build a box around the filter and seal it to the hood, but just haven't got to it.

Man... That hpfp gets super hot, lol. Not sure how effective the cooling of the fuel going into the hpfp will help, but its a good idea. A friend of mine actually put a fuel cooler (like an oil cooler) and he said he was shocked at how much his V8 monticarlo ran. But that was with a carb. That hpfp has burnt my forearm more than once when I didn't let it cool long enough ( the metal hose in the turbo side of the valve cover ).

One worry of insulating the fuel line is that it can't dissipate the heat from the high pressure pump. Is radiant heat from the turbo a bigger source of heat for the fuel or is it the pump? Not sure.

If you are stock I am going to say no the turbo is well shielded and more or less hidden to the fuel line Downpipe note so much. How long of a run are the HPFP lines as the pump is on the head I doubt the lines are that long so the fuel spends little or no time in the line to pick up heat.. I would guess the heat in the pump and the line are from location of the pump on the head and heat transfer and the pumping action generating heat when the fuel is compressed to however many billions of pounds for the DI sysyem..

I used some DEI gold wrap on my intake. I am happy with how well it seems to work, I sure wouldn't do it just for looks.

After my turbo install my header the coupler to the intake on the kit was shorter so it brought the turbo side of my intake down a couple inches and with the header being much taller than the manifold, at one point only being 1 inch or less from the top of the header. Since I had the header coating and it would take a couple days to get some parts to correct in I decide to drive to work and back the next two days as is just to see (15 miles each day).

I kept a close eye on it and I guess the coating does do its job, it started to shine the plastic on the cobb intake but didn't really start to melt it through, but it wouldn't have lasted very long I am sure. But I figure still impressive not melting plastic a finger width away from the top of a turbo header even for daily driving.

So I got a 2 inch spacer built to bring the intake back up to the normal location and wrapped the intake and then went out and did a half dozen data log pulls, and then I checked the temp under the header section of the intake and the wrap was almost unnoticeably warm to the touch. (note it was not raining on the intake during the pulls, that picture was after it set out in the rain overnight with the cowl off)

Anyway it's hard to get good info on how much coatings and wraps really help, and that is my experience.
