Wrapping Cats/exhausts Tamora
Discussion
I'm looking to reduce the over all cabin temp in the Tamora by wrapping the manifolds,cats and exhaust . Has anyone done this? Is the reduction in temperature worth the hassle of removing the system? I believe the manifolds can only come out from the bottom of the engine bay.
Any info would be great.

Dom steered me away from coating, wrapping was his suggestion for the 4.5. I used extra lagging under the tunnel cover and sealed in the apertures on the bulkhead to reduce heat soak, I also had a tufnel gearstick stem but never fitted it before selling. The matting welders use to protect surrounding areas is what I used.

Hi Buzz
My Tamora has coated manifolds (Camcoat) - just the manifolds - done when the engine was rebuilt. Think it was about £400? The work was done at HHC but I think you are right about the access from below...and I think you might have to loosen the engine mounts too in order to clear the chassis?
The coated manifolds look really good and once the engine is switched off you don't have to wait long before you can touch them! My aim was to reduce engine bay temps rather than cabin heat soak - cant say I've noticed a difference on that front?
Due to the curves / radius and the fact that they are close together, wont they be difficult to wrap?

Buzz, when we went to the Prescott Revival, there was a chap there with a Lola that had a fantastic looking finish on his V8's exhaust manifolds, but I can't remember much more and regrettably I didn't make a note. He did tell me and it defo wasn't camcoat. But someone else may know him and identify…… If i can find a pic, I'll post it.

Hi Geoff was it the guy with the GT40?
As for the coating I have used camcoat on the V8 and the manifold temps were marginal between coated and uncoated I think the temp diff was around 20*c and that's using a professional infrared temp sensor from work altho' ceramic looks better and does cool down quicker it's no full cure for heat soak. I'd rather use the titanium heat wrap we use on the manifolds in the power industry . I'm just trying to gauge what the over the counter wrap does and how good it performs . The heat soak comes from the cats which will be definitely getting wrapped along with the 2 exhaust pipes down as far as the rear bulk headI'm just wandering is it worth do in the exhausts manifolds as well

Buzz, this was the car. Someone will know it or the owner (not in photo). Can't help think you'll just move the heat under the car, to where it has less room to dissipate. And you could end up shoving a lot of heat into the rear silencer and boot area….. There are vents in the bonnet above the headers for a reason.
Ah right the Gardner Douglas mclaren T70 replica. You're right it will move it further down the system how ever I'm only covering with wrap to just after the seats I'm also putting in very thin alloy sheet down the back bone of the chassis to defect heat from the two exhaust pipes...similar to that you see on prod cars the...bonnet vents are great for getting rid of manifold exhaust heat but because the lower cat is further back the heat radiates on to the tranny tunnel etc the heat since the 4.3 went in has increase dramatically... I'll chat with you more when I see u at the NEC next Sunday

Thanks for this Davey. I have a cunning plan but First I need to stop using my car and actually get it up in the air and get the zorst,cats & manifolds off . The engine needs dropping off the engine mount to get the manifolds off Dom was telling me. It sounds a bar steward of a job but I have the means and the will power! Should hopefully get in done in January
I'll post pickys etc
