just wrapped the exhaust manifolds right up to the Y piece and the difference is great ,engine bay temp is not as hot after a long thrash ,coolant temp stays lower in traffic and it is quieter at the front ,got the whole kit from rimmers which was two heat wrap kits plus stainless straps to hold it on and took me 2 hours to fit it properly cost £131 total with delivery. and makes my chimaera 4.3 even better.

Hi Ian,

Was thinking of doing this myself once, but was a bit concerned about it just pushing more heat further back down the Exhaust to the un wrapped parts,these being close to the bodywork and other internals running from front to back.

I Know some other pips have done this and it has improved engine temp, but please be aware of other possible probs could occur from doing this.

Did u go to the Northants TVRCC meet on Thursday??

IMO that pushing heat further down the exhaust thing is a bit of phooey, yes the system further down will get hotter than previously but there's never going to be as much heat as right at the start of the manifold, the system gets cooler from then on relatively speaking, plus the system gets further from the fibreglass body (the manifold is the closest bit) so I would have to say it's a win-win situation. I've done lots of cars and never had any sign of a problem.

Joolz did mine and with the pre-cat removal too there is a noticable difference.

I would have it done.

yes i did go to the tvrcc meet on thursday ,ive got the starmist green chimaera 4.3 .I did consider the probs of pushing the heat further down the system but the experts say it is ok and i will monitor the temps with some temp strips i can get from my work just to check that other things do not get too hot ,but so far its ok and thats with it stuck in heavy traffic and a very heavy blast on a private road ( honest ) ,and i think i will take it off at some stage to check that the manifold has not started to corrode ,but i'll give it a while yet as it really has improoved underbonnet temps.....hey i bet rockingham was a blast..ian..

.for reference, has anyone got a photo of their wrapped manifolds they could post on here?

im looking at this mod for my car but i've got visions of Nora Batty's legs poking out from either side of the engine..is it realy like that?

and has anybody + or - experience with ceramic coatings?

cheers..heliox

I am sure there has been some postings on ceramic coatings before on one of the TVR forums,have u tried the search engine.

yes i've read the threads about it and found these people through a search

www.camcoat.u-net.com

im just asking for peoples oppinion who have perhaps had this work done, as this methods is only realy effective(and guaranteed) on new manifolds..but does it work in reducing heat, thats what i'd like to know.

Had my manifolds done by them and it does work, if somewhat expensive at £265!!. Engine bay temperature seems better and engine runs smoother (or is tht my imagination?). Looks the terriers tackle as well.

If you have a look in Demon Tweaks Catalogue there is usually all sorts of coatings and wraps for exhausts.

What happens when it gets wet, when I wash the car the inevitable water splashes on the warm manifold through the slots in the bonnets, will the wrap soak or expel water??

It soaks it up. Soon after starting the car, you then get steam coming out the bonnet vents for about 30 seconds, which is pretty cool
My chimaera has had wrap on for about 1.5 years now, lives outside in all weathers - seems OK so far...

You can get some spray-on stuff to seal it, but I didn't bother. Not usually a problem, but occasionally if it's been standing in heavy rain it steams for a couple of minutes when I start it up.

The heat wrap made a huge difference to under-bonnet temperatures (was previously melting bits round the headers) and the rate of electical/electronic failures under the bonnet seems to have dropped too.

Well i was sure i read somewhere about negative points of doing this but all i have seen on here are positives so looks like i might give this ago,especially as i ve just changed my starter motor after it being fried.

I beleive u can get in different widths, what was the best to work with in your opinions.

I only tried the 2" wide stuff, which was fine. (one 50' roll was enough to do both manifolds.)

I saw on the Griffith board a thread about exhaust wrapping

Has anyone else tried the Camcoat ceramic coating on their manifold that 'TVR Griff 4000' has used (his profile hasn't been set up to email unfortunately)?

I used 1" stuff around the fiddley bits, then 2" after all the pipes had joined together. Hint - wear surgical gloves & bend a wire coathanger into a long hook (plastic coated preferably)
The gloves will stop your hands itching for days (wish I'd done this) & the coathanger will save you loads of time pulling the wrap up between the engine-bay & the manifold.

You have all convinced me it is a worthwhile job, another one to add to the to-do list! If anyone is able to post a pic. of the finished product I would be interested to see what it looks like.
Thanks,
Chris

I'm another to be convinced this is a good thing to do. I would be interested to know (from those of you who have already done this) do you wrap the pre-cats?

Cheers,

Butty

Yes. I'll try and get some pictures, its really very straightforward and (IMO) well worth doing.
