Heat Management
 

Hi everybody.

I have been experiencing a lot of heat under the bonnet lately.
Was advised to exhaust wrap it or to have a go at ceramic coatings.

Been on the net trying to read more about it, and the more I read, the more confusing I get.

I am based in the UK, so it came up some companies that offer those ceramic coatings: Zircotec and Performance 1 Coatings. Has anyone heard of them? Any inputs or reviews on the said companies? Any advise on what to do?

On the exhaust wrap side of things, I was bombarded with huge amounts of offers over Ebay and Amazon. Some very cheap as £10, another ones expensive at £120.

I REALLY don't know what to do....
But I need to keep my temperatures down... :scratch:

Why do you think your temps are high? Why does it matter so much?

What year RX7 do you have? Modifications?

It used to be made by a local manufacturer here in Auscalled ACL and was used OEM on Turbo ford falcons. Probably less than half the price of inconel and very easy to work with. Its bassically two sheets of aluminised steel with glass fibre centre and a fancy scalloped pattern that holds it all together and facilitates bending (and staying where you bend it!) cutting with tinsnips seals the cut, and ive blow torch tested this stuff to bright red and it wont fail.
I kinda think inconel and mica used as a heat shield is a bit of a wank - as long as you can create a shadow between the source of radiant heat and whatever you are trying to protect while maintaining an air gap that allows some air to move then jobs done. If you want more then you can get the fancy super non conductive materials out and use as insulation. After thatn you probably want to look at ducting air onto the problem areas and after that maybe create an exit for said air (louverred hood)

Thats ACL stuff works wonders, ive used it before on a friends s14 as a heatshield between the turbo amd the firewall/head. Dropped the tempatures heaps! No longer melted the pretty paint on the SR's head

Vented hood,.. let some heat get out.. honestly why are you worried about it? Or you want new things to do?
