Reply With QuoteHey Marty, I have got a similar setup and I haven't had any issues with heat. Any reason for adding extra shielding?

Hi all,
Can you have a look at the photos and let me know what you think of my heat protection. I have a TD5 D2 and have installed a second battery on an ARB tray. Firstly I added a piece of heat proof matting against the metal plate on the side of the battery. Yesterday I decided to add a second piece stuck onto the existing turbo heat shield. Theory is that this second piece will slow down the paint on the bonnet going crazy and also help in keeping the heat away from the battery. Now I am worried that I have effectively put a blanket on my turbo and will be increasing the turbo temperature as the heat can't escape. Do you think this second peice of heat proof matting might possibly cause the turbo to overheat?
If you are woundering where I got the matting from it was given to me from a moulder and can handle the heat of molten metal so should easily be able to handle the heat from the turbo.
thanks, from Marty.

Hi JMK,
I felt the battery tray and was suprised how warm it was, plus above the turbo is where my bonnet is the worst. Also I had some of the matting left over so thought I might as well stick it on. Only thought about it later that it is designed to radiate a certain amount of heat and i have reduced how much is radiated so might be increasing the heat around the turbo.

I'd just attach the matting to the battery area then......

Has anyone ever considered or made a heat reduction bonnet for a disco to move some air via the rear of the bay? I know AEV in the US do them for Jeeps, but it'd probably make a bit of difference the the efficiency of the turbo to bring the temps down in the engine bay.

Hi JMK,
I will remove the matting off the heat shield and just leave it around the battery then. It sounds like nobody else has added any to the heat shield.
Boxer,
You reminded me of my old XY falcon, a couple of washers under the bonnet hinges to make an air gap at the rear of the bonnet. Don't know if it did any good but sure looked tough.

Hope that's not asbestos.
How about making a insulated liner for the bonnet?

Hi Simon,
No it is not asbestos. I don't know what it is made of but it is what moulders now use for heat sheilding.
I have now peeled it off the heat shield and will just leave it on the side of the battery.
For the bonnet I think I will just get it repainted and then it should be ok for another 8 years.
I was looking at the bonnet and it would be easy to add a couple of washers between the bonnet hinge & bonnet to lift the back slightly. This would then create an air flow from under the bonnet and up the screen. Would be effective at highway speeds but not in slow going.

i looked into this when i had the jeep and what i found was that if you let air escape out the bonnet than there is less air going past the gearbox and apparently it would make the gearbox cooling a slight problem letting air into the bay near the turbo would make sense as a lot of turbo cars have a vent near the turbo just need to make sure its not goinhg to redirect the flow away from the gearbox, ill happily be corrected if im wrong,Originally Posted by Boxer
