Heat wrapping zorst??? Worth it?

Gonna get new manifold, shot blasted, paint it and wrap it i think. Any ever done it? Isit woth it? And where would i get the wrap from? (good stuff)

Cheers,

Dom

I've heat wrapped in the past and I think it helps. There are people that say it can crack manifolds but I've never had an issue. Maybe with turbos it may with the higher temps.

My engine bay was noticeable cooler after a blast and (stupidly) on my Honda I could touch the manifold breifly. It still burnt me, but not as much as it would have and I didnt get a burn mark. Stupid way to test but thats me!
Also the hotter the exhaust the easier the gas can escape, apparently improving the scavenger effect in the cylinders. (helps bring in the intake mix).

You need to wet it when you start it up for the 1st time as I think it helps shrink it? Personally I'd damp it down when wrapping it, the fibres get everywhere and itch like buggery for days after. I didnt damp it down and me and the missus were going mad with itching after we did it!

I'd use it again for sure.

sweet, any idea where you got your stuff from??

If you have the manifold in your hand do it, as knightly says though, I've heard some cracking manifold storys but if your wagen is n/a do it, heard slot of good shiiiiiiiiii bout it bout it!

I got some from e-bay but it wasnt as long as advertised.

Apsley motor spares used to do it, they seem to do everything!

How sad am I!

Having read a bit about going large on Zorsts, I was surprised to hear that they are all about heat transfer and not just gas. A turbo works from the energy not the flow force of the gas.
With this in mind, wrap that manifold well.

no turbos unfortunatly, its a g40 4-2-1 steel, been battered about to fit a g40 with a huuuuuge sump by the looks of things, £50 tho, blasted, painted and wrapped should look cool though.

As we are on the exhaust subject, is there any different in performance/longevity etc of gasket as im going to need one, any different types etc? Who from?

cheers

also if i were to start a progress thread/help me! thread which it will innevitably turn out to be, on my enginer conv what section would it go in?

For a help thread the best place is the car specific section but for the build up it would go in the garage.
Put it in the garage for now, I can build a new tech section from there if required later and we work out where it actually is best to share the information.

id love a ceramic coated one, god knows where could do that though? im sure i read that heat wrapping can cause dangerous egt's on turbo engines, maybe thats on a stock, poor flowing manifold?

ill do a bit of research on this i think!

sweet cheers guys
