Exhaust wrap - a good idea?

[Mark Halligan]

Is it a good idea to wrap cast iron exhaust manifolds, or will keeping the heat in render the casting more likely to cracking. I am sure that I heard/read somewhere before that it could cause a cast iron manifold to overheat and damage it??

Cheers,

Mark.

I would wrap the ss downpipe instead of the cast manifold it could overheat and crack

Im thinking of getting a heat jacket for the exhaust side of the turbo. Would this be a good idea?

Hi
I´m having mine ceramic coated in USA.
That really works on our racecars.

We use ceramic coating 2 pack compound from belzona molecular, i coated over the small cracks on the manifold, i will check to see if the fix has worked, but we use it to protect bearing housings (water cooled)that the orange hot metal passes over. Seems to work well on them (they are constantly running 2" under a 1200 degrees c slab of steel). Got a pack in the garage and might try it on the downpipe, cannot see why it wouldnt work.

Too late/broke now to get it ceramic coated, I am still thinking about the wrapping it though. I repainted it tonight and cured it in the oven, while the girlfriend was out :mischeif:

This is the product which we use for ceramic coating. it produces a glossy finish and this one is blue, we have red, and grey also (even though there is not alot of difference in colour, its more like grey with a touch of red/blue)

This might help. Its by Dhalback racing.

Question: Where can I buy such heat wrap/tape ?

[Graham]

It Just looks like fire blanket material, probably fibre glass one side and shiny on the other to reflect the heat back in.

A friend heated up the head of his Lotus Elan in the oven to install new valve guides. The oven stank of oil for weeks afterwards!

Mark has previously baked things in the oven while his missus is out, cant remember what tho'!

LOL @Mark. Next time i see her.......

I thought of doing this with mine too. BUT.... the only problem being is that should the car develop an oil leak and it gets on that wrapping it catches on fire very easily.

Almost BTDT.

The choice is yours, it shouldnt leak oil, but then **** can happen.
