can any one tell me the benefits of using exhaust wrap on my manifold and down pipe... other than simply reducing engine bay temps.

also whilst exploring this field ive noticed that many places state do not use on cast iron manifolds..... is the mk3 fiesat si 16v manifold made of cast iron?

cheers 4 any help

Alreet Dan! Get a pic of the manifold and I'll tell you what it's made from if no-one else knows

Exhaust wraps help to retain heat in your exhaust system, which increases horsepower while reducing radiant heat damage. By wrapping the exhaust system it maintains hotter exhaust gases, decreases the density, and allows the exhaust gas to exit the system faster! Greater exhaust scavenging is produced and lowers intake temperatures: that equals more horsepower.

hello the exhaust heat wrap turns the manifold into an oven and it fatigues and cracks the manifold. it is only really designed for rally/race cars and to be honest im not sure that amature drivers would benifit from the little power gained. the only car that we ever put the heat wrap on was a mk1 cortina and mk1 escort because they truly do benifit from it becauue the pre-crossflow engines had the inlet manifold directly above the exhaust manifold. i know some people will just argue with what ive said but if they have worked building rally cars for a few years then please dissagre if you want.

cheers chris

Is it worth me wrapping my four branch on me 2.0?? i think the heat causes the starter to feck up , cud that be right?? or is it just the high compression feckin the starter??

[s1chris]

well why not make up an heat shield for the startet motor. i do know what you mean as my erst had the same problem. depends on what you want to use you car for aswel doesnt it. Whats your exhaust made of?

I can confirm what chris has said.

He did mention this to me and i spent a day or so researching.

Basically the heat that usually escapes is contained within the manifold.

so it runs so much hotter - white hot on the point of melting sometimes.

This is not good for the metal.

What I'm planning on doing is wrapping the inlet tracked to stop head from the engine bay getting to my charge air - ill also be protecting vital opponents and sensors.

That way every that needs to stay cool, stays cool and the exhaust wont disintergrate!

Im also looking at a heat shield that will hopefully dissipate the heat just where i want it

[s1chris]

cheers for backing me up there simon. where did you find out all the infromation?

yea i might make up some kind of shield. Cause as it is the starter has a bit of hard time turning the engine over due to the high comp ratio but after a long run when i go to start it again it takes a while for it to be able to turn it over . My car is a daily runner so need to be as relible and useble as possible hence one i havent gone to mad on tuning and stuck to quite a mild state of tune . Im not sure what my four branch is made of its a TrustElectrical mainfold

Sunil - I don't think I've EVER posted in one of your threads or spoken to you! So "hi" first! The starter problem is quite normal with 2.0-converted Fiestas isn't it? Heat shields/local wrapping of the manifolds are the norm I think, to combat the heat soak effects on the starter motor. If you chuck a post up in general I'm sure you'd get some stories back from ppl

Im pretty sure the trust electrical manifold is stainless steel

i have exactly same prob on my 2L starter sounds a bit 'lazy' but its a brand new item with all new cabling and battery

Hi mate, Cheers for the reply i think i will try a bit of heat wrap near the starter area and see how it fairs.

Yea mine is a new one aswell. Good to hear ur havin the same problem (as bas as that sounds lol) at least i know it aint cos ive had the compression upped which is what i thought and was thinking of getting the starter uprated somehow
