Which exhaust wrap for turbo?

[Floodie]

Hi all

going through doing all the finishing touches to my clio TT project and im on to protecting the brake lines that run along the back of the engine bay AND the gear selectors which will run very close to the downpipe.

Any idea which exhaust wrap to go for?.. i ideally would like some idea of what temp a mapped k04 runs at as i dont want to buy a wrap which isnt up to the job.... For instance there is a hardcore "magma wrap" which keeps up to 980C direct and 1370C radiant - but others are all typically 550C direct and god knows what radiant.. bit of a difference there... Is this Magma wrap overkill? is that temp only given out on really high powered 500bhp+ cars?

Thanks
Dave

Ceramic coating?

you want something like that

most turbo's running increased boost and on a modded car (remember oem are much more cautious) will reach EGT levels of around 1000deg C meaning the manifold and housings start to see up in the 700-900's. I'm generalising quite a lot as it depends a lot on the size of turbo. Big exhaust housings reduce EGTs a very noticable amount

Yeh Gray had a think about that mate - unsure if the place my cup is booked in at do it. Will check when i call later... Also, price - this project has turned me from having a relatively decent amount of money to a tramp ... jokes aside, the wrap is around £25 and ceramic coating is???... sure its a few hundred.. but youve raised a point, i'll check when i call them later, thanks

Flan made a nice heat shield which covers almost all the brake lines but im also wrapping them in a snug heat reflective shield along with wrapping the gear selectors with it too... Maybe im going over kill but someone mentioned "brake fluid" boiling and i just want to do everything i can to prevent that for obvious reasons!

Thanks Dan - yeh had a look at those. Tell me if this is right or not as im fairly new with FI, but i was worried about wrapping the turbo itself AND the manifold as the high temps might crack the standard k04 manifold?.. I had planned to only wrap the downpipe....

Your comment about most mapped tubbies running at circa 1000c has made my mind up i guess....

the downpipe wont get even nearly as hot. The turbo is the restriction in the exhaust that causes a heat build up, so the hottest place is pre-turbo. wrap should help to some degree with cracking as it can stabilise the rate of change in material temperature and it's fast changes that cause expansion/contraction, and ultimately cracking

OK dan cheers for that... what i'll do is put shielding over the brake lines and gear linkages.. the gear linkages will virtually be touching the down pipe thats all...

I'll also get the custom down pipe wrapped, hopefully that will be sufficient... i suppose its not like its going to be running any insane power right now... "just" a remapped K04
