ceramic coated exhaust

[timtoo]

I understand you can get you header/extractors coated inside and out with a ceramic polymer which will cut down under bonnet temperatures dramatically. This also cuts down in cabin temperatures.

Has anyone had any experience?

I have heard of this being done have you tried a search using the Drop down Bar above.

Yep, tried that with no success. I heard it cut down heat by 30% which is pretty high. I am in oz and the cabin gets v. hot as the fibreglass does not draw the heat away.

I have priced getting it done (cost approx $3K) or GBP1000 and suspect would need to take engine out to get to the nuts. An expensive exercise particularly if I cant get any ringing endorsements.

Also tried the TVE chat room but had no success there.

sounds like a similar idea to heat wrapping for turbos etc. trouble is the heat has to dissapate somewhere.

Had mine done and as well as making the engine bay look a lot neater it certainly cut down the heat.

Think mine cost £250-£300 from a Company in Gt Yarmouth who do lots of this stuff.

HiPerCoat have a distributor in Oz:

HPC Australia
6 Watson Road Industrial Park
Leongatha, 3953 Victoria
Australia

might point you in the right direction.

I wrapped my exhaust with the silica fibre stuff and it works a treat at reducing underbonnet temps but you must use it with stainless exhausts as the mild steel will rust through in no time other wise.

For thos in the UK these are the people you want www.camcoat.u-net.com/Exhausts.htm

They are often used on Caterham race spec exhaust systems as they reduce under bonnet temperature (as mentioned by others) but also improve performance by improving the flow rate of the exhaust. Well worth the money from what I'm told.

What impact did it have on the inside cabin temp?

This I have also heard, so be carefull. ie:If the ceramic coating ends where the exhaust passes the starter motor, you could be looking at a roasted starter, in effect. Sorry if I'm pointing out the obvious.

Temperatures under the bonnet have definitely reduced, but have noticed no increase in cabin temp, but then again I've got air-con. Noticed engine runs smoother though.
