Richard,
I dug up my results of heat reduction test after installing FatMat in the
BN7.
This was done last summer using a digital infrared thermometer. I live in
Atlanta.
I think the biggest heat culprits are air leaks from the engine bay through
the firewall and heat convection through the firewall, toeboxes and fresh
air ducts.
Check out the firewall temp reduction.
See below:
Before: After
Outside Air Temp - 96 same
Engine Temp - 170 same
Exhaust Manifold - 300+ same
Firewall Temp - 122 107
I ended up retrofitting it all the way up the firewall to the shroud. I
covered the box shaped air duct that runs from side to side, as well. I
completely covered both toe boxes and recessed areas for pedal assembly too.
(I had already done the floorboards, transmission tunnel and rear bulkhead
years ago)

What is the best product out there for a heat and sound barrier? I know this
has been much discussed in the past. But, I was not interested back then -
and
I have not been able to find the thread in the archives.
