I am looking at powder coatings for these parts, specs say they will withstand ranges 800F, 1000F and 1200F.

How hot do the items listed get on a cossie?

Anybody tried powder coating?

I have heard of over 800deg for turbo ex housing and manifold, hot enough to see into when RED HOT!!!!!!! dont know of peak temps though, doubt it his 1000deg.

OK, I thought ceramic was the hot form of powder coating., I saw some really neat exhaust manifolds with high temp powder and thought it was the same.. will get someone to do ceramics then.

Sib got his exhaust manifold powder coated in April and it burn't off straight away with a nasty smell.

Theres a place in Warrington I think its called CamCoat who does ceramic coating its a little expensive to have done but I beleive it helps keep the heat into the exhaust so helping flow and also keeps the rest of the under bonnet temps down too !

Damn right it did! And it was supposed to be some clever high temp powder coat.

I now use BBQ paint from B&Q etc, and it's still there 1000 miles later and despite some 400 bhp+ track days.

I won't be bothering with any other exhaust treatment now as it's £4.99 a can and works fine!

Hi,

I have put a lot of effort into researching various temperatures in and around the engines of Cosworths and have found the following.

Pre turbo manifold temperatures can reach 900 degrees C max when pedalling hard which is around 1650 degrees F

Temperature drop across the turbo will bring it down to around 800 degrees C which is around 1470 degrees F at the exhaust downpipe

Hope this helps.

i agree with mike above.

i have 4 thermocouples in my ex manifold, and one after the turbo so can say this for sure on the chip that i run (turbosport stg 2).

the temperature will depend on the mapping that you run, as a leaner mixture will burn hotter etc

Gavan Hood

Sounds like a good idea with the thermocouples... can you advise on what you used there.

BBQ paint... way to go...

I heard of the ceramic paint and that it might help push heat out of the enigine bay, I found one place that does it for about 70 USD... but dont have the details, an american company that has agencies world wide...

When i find it I will advise...

reality

It's a great idea to trap the heat inside the manifold and crack it..

2wd exhaust manifold and downpipe are for sale. £100 and £60 respectively.

manifold has 4 x thermocouples and is ported to match gasket opening size

downpipe has a lambda sensor boss
