Heat Wraping Exhaust And Manifold

[Bsa]

Hey everyone I was wondering is there any point in heat wraping exhaust and manifold? Also what difference would a turbo blanket make?

[StevenCJR31]

it helps with exhaust gas velocity and keeps the heat out of the engine bay. . .but it can cause the exhaust pipe to crystalise/fatigue and eventually fail

Keeping everything cool sounds better. What heat wrap is best

I've found heat wrap was horrible, got a decent brand, wrapped my manifold, was itchy as hell to put on ( my arms were bright red by the end of it) didn't make any difference, still got hot and after 3 months it cracked my cast iron manifold.

what is alot better is making a heat shield out of heat reflective materials, bunnings sell the stuff and cut with a tin snip, that I did notice a difference that my intake pipes stay cool/lightly warm and oppose to roasting.

I think I know the stuff do you have a pic by any chance

[WYTSKY]

can't remember what it is called, but it looks identical to this, can get thicker/thinner versions of it so it is more pliable.

Ford sell similar stuff to the bunnings but is thicker. It works quite well I have found.

They use it for the XR6T heat sheilding.

For the stock manifold I trimmed the stock shielding to clear the gt 30 housing and it works great. For the dump pipe I used fiberglass wrap from Repco. Itchy yes, just man up. But after wards under bonder temps were lower, and I can physically touch it after long drives so it does work.

That looks like the go might attempt this on the weekend
