Hi guys,

Has anyone got any recommendations for an engine bay heat shield set, it seems mad not to replace my 23 year old flakey heat shields while the body is off.

I'm considering this set from Central TVR, if anyone has bought this kit I'd be keen to know if you were you happy with it?

https://www.ebay.co.uk/itm/274001237942

I'm also open to hear about other options.

Thanks, Dave.

I've not seen any set that fits well and in some the material quality is not great. I've made my own patterns and sew them myself but before you ask this is not cost effective. I'm not a machinist and using a hand crank Singer they just take too long to make. Long time = high cost when you have a business to run.

Central TVR have two options:

1. The basic kit covering what you see

2. The full kit that includes the tunnel





https://www.centraltvrparts.com/product/heat-shiel...

Central TVR do say they use the OEM material scratchchin


Or there's this kit on the PH classifieds, it's cheaper and claims to be superior to the TVR factory fitted panels, also comes with high temp glue and rivets scratchchin

Has anyone specifically used any of these kits and if so were you happy with the quality?

Thanks,

Dave.

Hi Dave,

I bought the set from Central TVR and the heat shield for the bonnet from them. I am very happy with their service and the quality of the material. They also supplied me with pop rivets and washers.
For the tunnel area, I bought the heat shield on a roll, from the internet cutting it to size as I went.

Old situation:

Perfect Simon, that's exactly what I wanted to hear and looks spot on to me thumbup

Obviously the panels are pop riveted in place, but I assume you used a high temp adhesive too?

I've used Everbuild Heatmate to re-attach my under bonnet heat shields which worked an absolute treat and was the only thing I found that properly lasted in super hot TVR engine bay environment, everything else I tried only lasted a few months before the panels stated to fall off again.



At £7.25 a tube it's very cost effective too, but what do others use?

Many thanks, Dave.

Central do this kind of work daily.
I’ve looked at the TVR PARTS ones which are more expensive.
I think I’ll go for the Central ones personally.

I’ve just noticed the loom wiring comes out centrally on the bulkhead on these pictures. My later car with wiper motor inbound of the body comes out more to the passenger side.
You obviously cut the hole yourself as I bet the hole is never in the same place twice biggrin

Agreed Alun thumbup

I looked at Chimaera Parts Online and for the same money as Central TVR charge for the inner wing panels and the bulkhead panel, they only supply the two inner wing panels.

https://chimaerapartsonline.co.uk/product/inner-wi...

If you then add the bulkhead panel on the Chimaera Parts Online website you're up to £150, and with postage that's the same money as this far more comprehensive full kit from Central.



Using Central TVR seems like a no-brainer to me wink

I purchased a full set on my car from Central - and was happy with result. I tiny bit of trimming required but couldn’t fault the product.

The bulkhead panel was formed around the loom opening.

Ok I think I’ve got it now. I’ll take a better picture

Hi guys, maybe I should have said that they have two versions. Obvious now, but the older one like mine (1993) and the more modern one.
So order the correct one thumbup

Thanks everyone, great info and it's good to hear the Central kits getting well reviewed.

For the bits you see (the two inner wings and the bulkhead) the three panel set from Central seems like a no-brainer.

For the transmission tunnel where it can't be seen I'm considering self adhesive aluminum heat shield GlassMAT™ closed cell foam on the roll.



From these people....

https://www.carinsulation.co.uk/product/15m2-glass...

For the unseen transmission tunnel areas it appears to give a number of advantages:

1. Its very cost effective

2. It offers sound deadening

3. Being adhesive it can be stick over the old insulation in the tunnel saving time and cost

I'll link Alex Wheatley to this post and let him choose what he prefers as he'll be doing fitting.

Thanks again, Dave.

Hi I found the following company on a Lotus Forum.

You need to ring to order but website shows detail and Spec.
they cut it off a 1 metre wide roll.

I purchased 2 metre length for £40 Delivered

https://www.camthorne.co.uk/product/foil-backed-gl...

Seems to be very good quality rated to 600C
I used this to replace the bonnet heat shield on my Griff.

Not tried it in anger yet seems to stick well. I re did mine before a full respray.
Did not need to worry about the paintwork.
Car due back from sprayers today. so will be a few weeks before i get to try it out

Hi Dave

I don't know this specific product - but I ordered something very similar (albeit slightly dearer) as I had the same idea regarding the noise reduction and killing two birds and all that. But, when it arrived I found it wasn't very robust. The Ali layer was very thin and because of the soft backing it made it very easy to penetrate through the Ali layer. Given where this is intended to go - I would think any small stones would certainly penetrate it if they were to be flicked up. In the end I went down the Central kit route for tunnel and then Dyno mat the interior under carpet.

Not saying don't get this - but maybe one to be mindful of.

So I've discussed this with Alex Wheatley who will be fitting the shields and he advised the full pre-cut kit from Central TVR is the way to go.

Alex seems to think the full kit from Central TVR gives more coverage in the tans tunnel area than TVR gave the car from new, so he's saying it'll be an improvement. When ordering on the Central TVR website it offers you the suggested logical additions of special high temp spray adhesive and rivets, as these were very reasonably priced and I'm assuming tried and tested by Central products I added them to the basket too.

Total cost £173.06 plus Alex has quoted me 2 hours to fit which seems very reasonable, I have to say the heat shields were an expense I hadn't really budgeted for but it seems crazy not to replace them while the body is off. Thanks to everyone who contributed to this post this morning, this is exactly how the PH forum is meant to work and shows what a great community of helpful enthusiasts I have the privilege to be connected to.

I hope this posts helps others and to complete it I will be sure to post some photos and feedback once the Central TVR kit is fitted.

Dave.

Just to assist other people in the future, I will add my 2ps worth. I bought the Chimaera on Line heat shields and was very pleased with them. Easy to fit with the supplied rivets and glue and 18 months / 2,000 miles later they still look brand new.

I also bought the bonnet heat shield and a roof cover from them, which I am equally pleased with.

They don’t do the heat shields for the tunnel, which will be a disadvantage to some people, but mine appeared to be OK and didn’t require changing.

OK this may sound stupid (and it probably is) but at Glym9 we looked at the heatshield material on our Chims, Griff and Cerb and the only thing that seems to fail/go missing in places on our cars is the outer aluminium foil-like layer. Between us, so far we couldn't come up with a valid reason why in this case, where the stuff underneath is intact, you couldn't just take some of that gold foil heatshield material (for instance) and simply glue it to the existing heat shields...

I'm sure we're missing something... or are we? smile

I don't think you are missing something, that all sounds perfectly very reasonable to me scratchchin

And this stuff looks ideal...

https://www.ebay.co.uk/itm/Self-Adhesive-Reflectiv...

But the saving isn't huge and my man fitting the stuff just wants a kit that's tailored to fit with minimum fuss, I agree too as I'm paying him an hourly rate for this kind of thing and with labour the recycling idea will likely work out no cheaper by the time he's cut the sections and stuck them to the original backing.

However, for others doing the work themselves I think its a great idea to re-use the backing, I'll ask Alex to keep my old sections if they come off cleanly and I can make up a refreshed spare set myself.

Good call thumbup
