buy someone just said they catch fire!!!! wayne at proalloy had lucky escape with his Lotus.

Would I be better getting it coated?

any views welcome.

thanks!

Personally i'd just have your manifold, exhaust housing and downpipe coated by Zircotec http://www.zircotec.com/

I've yet to have a bad experience with them and their coating seems to actually stay on when the surfaces are correctly prepared

Didn't Rod have a turbo failure that was partly put down to using one of these ?

id get it coated dont like the jackets

big_wig_074

steve (aka stav from redline) fitted one to his rx7,works really well,no issues im aware of

cossie.con

I have heard bad things about these one fact being that the oil can over heat and cause lines to coke up quickly and minimize the flow leading to premature turbo failure

Mark Shead

It fried the turbo I would not recomend one running the turbo hard.

I know u and I don't see eye to eye
but that aside I would get the turbo coated
I had one of those turbo covers cause a big fire
it just basically melted ,
I had to use an extinguisher,
it wasn't a cheap one either.
Worse thing is seeing someones car in flames,

Mark Shead

Have you coated your housing as I would recomend letting the heat out of it rather than keeping it in, The manifold and downpipe coating is recomended.

No havnt coated my new turbo
I was going to but I don't think I will,
Manifold and downpipe only for me then on your reccomendation.

Had one on my turbo ,nearly went up in flames(not a cheap one ) ,warren runs one on his ,had no problems ,how about doing the bonnet gatebil style lee

iTrader: (1)

Didn't that bloke from Car-unwise run one on his? Think that went tits up...

Do this around the turbo area ,should get the heat out a treat

i have been thinking of getting one for the 5,
i have had my manifold coated inside and out, and it is absolutely nowhere near as effective as the cheap crappy heatwrap i had on there before hand in mine i have almost no airflow over the exhaust so the coating doesnt work.
i will be wrapping it with a decent wrap soon.
if you dont have any airflow over yours i would think the coating wont be very effective.

Stu, I had to wrap mine, made a massive difference.







basically ive wrapped the manifold, the first couple of feet of the exhaust and the screamer pipe section, so basically everything upto the first silencer EXCEPT the turbo, as I didnt want to cook the turbo, so I normally run this shield I made instead to at least stop some of the radiant heat it gives off:

stu21t

yea i had wrapped the manifold and downpipe and all of the system till the boxes, bu i used cheap wrap and it made such a mess i took it off and was gunna get the whole lot coated, but i thought id start with the manifold.
glad i didnt do the rest now as it was a complete waste of time.

im going to redo it all with some good wrap, and also fit 1 of these between the manifold and head
http://www.ferriday.co.uk/gaskets/gaskets.shtml

and will make a turbo/manifold heatshield out of nimbus, might make a shielf for the filter to.


but i need to get it all back together and working first. lmao

Big Will_

Stu - who coated your stuff?

The Zircotec stuff i've seen first hand on a 9 second drag VW beetle that had no airflow over the exhaust and you could put your hand on the headers after a drag run...

Seemed to work really well and didn't seem overly hot even after road mapping etc.

Red16

What sort of cost would you be looking at to have that done?

Big Will_

For them to do everything - prepping, coating etc. for a manifold (4 cylinder), exhaust housing and downpipe (around 3 ft length 3" diameter) I was quoted around Ł500.

Gaz 88

Ived got my pd inconal manifold and decat zircotec coated that was Ł365 all in!

Chip

I would imagine that the item itself wont catch fire, but if you let it get dirty with oil and grease etc over time then that might.

Psycho Warren

iTrader: (5)

I think i will stick with a normal turbo heatshield i think!!

can the zircotec coatings be cleaned or so they get contaminated with oil and then burn like most other oil coated things??

My original ford engine bay heat shielding caught fire after i ran the antilag for a few minutes and filled the car with smoke. one of those wierd ones where the faster you went the less smoke but as you slowed the cabin filled with thick smoke...

Gaz 88

Where did you get the pressed alloy that you have put round your turbo and manifold from chip?

Chip

iTrader: (3)

Its not pressed ally its a honeycomb heat shield.
Its this stuff:

http://cgi.ebay.co.uk/HEAT-SHIELD-G2...item483b5ce867

And that is the company I buy all that sort of stuff through.

Psycho Warren

iTrader: (5)

looks like nimbus g2 heat shielding to me.

Psycho Warren

iTrader: (5)

damn beat me to it

Chip

Correct

update... So I had the manifold and exhaust housing coated by Zirotec.

and I also had the Turbo rebuilt with a metal bearing case as apparently this is what causes the failures when they get too hot through people using the jackets.

I also bought a Turbo jacket from Owen developments. Should I use the jacket on top of the Coating? I am thinking it will stay alot cooler now its coated and this will prevent any fire risk.

or is the jacket overkill and a bad idea?

Big Will_

Even with it coated Lee, i'd still avoid the jacket.

Send it back or flog it on

Chip

iTrader: (3)

Good call on the bearings, the standard cages cant take big temperatures.

Porkie

iTrader: (1)

thanks Will, Chip whats your opinion on the jacket?

Ive not tried one mate, so I can only go by what others have experienced and guesswork.

My worry with your car though is that if you shut the car off without giving it ages to cool down first then potentially there is a hell of a lot of stored heat in that housing with nowhere to go other than into the oil inside the turbo.
As lets face it, we both know that you wont leave it running on long enough all the time cause you are impatient.

So although I like the idea of them in principle if used by someone meticulous about cooling down the turbo properly, I just dont think they are LMH-Proof

Martin-Hadland

iTrader: (2)

Its fitted so Łuck off sausage fingers!



Anyhow, given that your brake fluid reservoir is about 10" away from the exhaust housing then I'd keep it on! Anyhow I will gladly remove it and fit it to my 500

Chip

iTrader: (3)

Fit a turbo timer as well then Martin!

OR, just leave it as it is and make a fortune keep changing the turbo for Lee if he does keep killing it

Martin-Hadland

iTrader: (2)

Lee isn't as stupid as he makes out, he will cool it down if he's told to.

Zircotec coated Fanimold and Housing and rebuilt turblow with metal bearing cage...





Reyland 'Engine Jacket'

Can an external water pump be fitted to pump coolant through the turbo once the car is turned off?
Renault 21s had these as STD, once you turn the car off a small waterpump turns on for 5 mins to cool the turbo.
Might not b a bad idea, I know it won't stop the oil gettin hot but it will help.


Also how well does the Zircotec work?
If you start the engine and leave it idling does it get really hot? Can you touch it at all?
Or does it NEED airflow to work? I know it will work better with airflow over it but wondered if it does anything while stationary.
With heatwrap you can leave it idling for 10mins and still hold the fanny mould, just wondered how effective it is in comparison?
Cos mine I don't notice any difference to a non coated manifold while stationary.
