Thread: Gearbox heat

Marcus, I put some metal heat shield under the floor, the stuff is the same as the moulded heat shield over your turbocharger. Supercheap have it in sheets about 300x500mm or thereabouts, not cheap at about $50 a sheet, I bought 3 sheets and used most of it. Made up cardboard templates then cut out the heat shield with tinsnips and stuck it on under the floor with globs of sikaflex, there was a thread on here a while back where someone has done this and I copied them. I had to do a fair bit of scrubbing of the underside before glueing, got soaked in the process, not a cold day job!
Seems to have made a difference, but I don't really do much towing these days.

2 other things I have found help a lot with footwell temps; I retrofitted the late model door bottom seals, there's a huge amount of hot air comes in past those useless older type 'seals'; the other thing is keeping the aircon directed onto your feet.

Hey Pete, do you remember how much of a gap you have between the sheets and the floor?
I'm happy to make up some tabs and rivet them in place to stand it out a bit, but I'm not sure how much of a gap I should have. I'm thinking between 15-20mm. That should give it enough airflow to keep the heat off, but I'm thinking I might not have that much room in some sections (?).
Cheers

What area are you in?

I'm in Sydney, so I think the Gold coast may be a little far to drive, but I'll look into a rubber supply shop.
