Exhaust insulation wrap
« on: April 29, 2008, 23:26:41 PM »
I'm making good progress on my new supercharger/intercooler setup.

But as it's gonna be a snake's nest of tubes, pipes and fittings everywhere running very close to the engine I want to insulate them.

I have exhaust wrap here which keeps the heat in the exhaust.

Am I right to think it will also work to keep the cold in the IC pipes????

Same principle isn't it?

I would have thought that you would be better using an alluminium wrap to reflect the heat away. I know they do the stuff in sheets, (self adhesive), but don't know if they do it as a tape. Just my oppinion, for what it's worth. Cheers Ray

Yeah I was thinking of that as well, but I have yards of it laying around so it seems a waste not to use it.

No mate you need something that is reflective to reflect the heat away. (radiant heat)

Exhaust wrap is like insulation

hello jurgen.

don't use the wrap on normal steel, it's starts to rust between the wrap and the pipe. i did it whit the blue capri v8, it only lasted 9 mounths before the first hole appeard in the headers. after that experience, i started to use ceramic coatings on the manifoild or use stainless manifoild's. unless you use stainless, i would advice against it.

its beter to use stainless pipe to build the headers or coat them whit a ceramic coating. no rust and it keeps the heat more in the pipe's, so you have less heat coming off it. the headers on the blue capri are now 7 years old, and they still look as new. no rust, no discoloration, well wurth the extra money.

Hi Paul, I'm not using it for the exhaust, I already have wrap on those.

It's about isolating the intake/intercooler pipes.

Gonna make a trip to the local DIY shop and see what's useful.

hello Jurgen.

i tought you want to use it on the headers.

for the intake, most use a heat shield for/on the place's where its hot and leave the rest open, so it can cool off. if you wrap it, the heat can't get in the pipe's and heat up the air, but the heated air in the pipes can not cool off. but this is just me thinking.

the only way to test this theory is to measure the temp off the air at the trottlebody, before you insulated it and after and see the effect on the temp.

Well the pipe going to the IC is about 2 cm away from the exhaust manifold.

The IC exit pipe goes in front of the engine, so that gets heates by the warm air coming from the radiator.

I think refelctive tape/insulation is best, shame about that exhaust wrap though.

hello Jurgen,

whit that cramped engine bay, maybe its a idea to go out site the engine bay. i have seen this a couple off time's, they route the pipe's true the inner wing, over the wheel, to the front and back true the inner wing to the cooler.

whit the blue capri v8, i did the same whit all off the electric's, water pipe's for the heater, fuel and transmission oil cooler line's, washer bottle and the brake line's, in order to hide it. it was alote off work, but it give's more room and a cleaner look off the engine bay.  

if the cooler isn't to big, you could place it in front off the wind screen, under the vent opening. it will requer some sheetmetal modfications.

a other idea is to use the same setup as some 4x4 have it. they mount the cooler behind or on top off the engine, and have a opening in the bonnet. in your case behind the blower.

just a few idea's. a few heat reflector shield's will do the trick.

That's a lot of work Paul.

I have been thinking about it but I will never get that done before Fordfair.

I'm also looking at an IC from a Vectra.

They are the same size as the radiator but very flat and have the hoses at the top corners, which could fit with a bit of modding.

phwoah! that's close.
Ceramic padding you might need,although that can be classified as an insulator like wrap. Ceramic padding is used in turbo blankets,to keep the heat in,and not in the engine bay.  I'm not fully sure if it wil be the answer,as I have yet to experiment it myself. I did manage to source some after hunting high and low for the stuff.

Well the IC was going to sit in front of the steering rack.

Going another route now.

Bought this now, which makes pipe routing very easy for me now.
