Where to get that heat reflective stuff?

[Anquetil]

I'm looking for that heat reflective silver stuff?

I need it to go around a CAI Box, anyone know where I can get it from?

Thanks

Do you mean roofing tape ?

It is shiny and comes in a roll and is backed with sticky black mastic. If thats what you mean any good builders hardware shop should have miles of the stuff.

Um not sure? Not really after a roll, something to glue to the outside of my CAI box. Like this but thinner...

You could always use a steering wheel cover...

that would look cheap and tacky man.

A steering wheel cover would melt. Clark rubber is the go.

The clark rubber stuff is not very effective, a much better deal is similar stuff but self adhesive on the foam side from Insulation Supplies, 330 Curtin Ave West, Eagle Farm 07 3268 7399

what makes that stuff better (apart from adhesive)?

I would think neither of them are good by themselves.

On my home built airbox I have:

- 1 layer of clark rubber foil backed foam (engine bay side)

- 2mm aluminium for structural integrity

- 2 x 5mm layers of neoprene wetsuit like material adhesive backed (internal side)

Data:

* Readings taken using Jaycar thermal probe device (-70 - +150 C range)

* Readings taken on a 35 degree C day after engine had reached operational temps

* Readings taken at front of engine bay, just outside airbox

Engine bay temps

Cruise at 60 km/h: 45 degrees

Cruise at 80 km/h: ambient

Mine is made of 1 layer outside 1mm alum sheet then 1 layer inside. The foam is a different composition. The clarke Rubber stuff was never meant to go in an engine bay.

Will be some time befor the car is running again, but i'll run the same measurements you did for a comparison. The 10mm of neoprene behind is probably your most effective layer
