Thanks Rob,

Rob and I have been discussing underbody restoration and undercoating among
other things. I have recently redone the clutch and drive shaft was
rebuilt. Have cleaned and undercoated and Rob is doing similar tasks during
his winter project. We were discussing insulating the drive train tunnel
for heat reflection, especially during the summer months. ( I loved the
louvered hood solution, went to the web site and checked it out, it was
aluminum ) I was considering buying some of the reflective insulating mat
from the V.B. catalog. It really gets hot in the cockpit in July in
Louisville. A friend said he had some ductwork insulation in his garage and
I was welcome to as much of it as I wanted. ( I think he cut me off about
6', and it is about 4' wide )

This stuff is a regular fiberglass insulation with a reflective, silvery
finish on one side instead of kraft paper like house type insulation. It's
about 2" thick. The way it is normally used is that the fiberglass
insulation is placed against the ductwork and the reflective surface is
exposed to the atmosphere. This reduces heat loss from the ductwork due to
the ambient temperature of the atmosphere outside the duct and it prevents
condensation from forming inside the duct. I used the principle in reverse
and had good results. I cut cardboard templates to contour to the tunnel
around the gearbox. I then cut the insulation the the outline of the
cardboard. I just duct tape (200 mph variety ) to tape the insulation
fiberglass side down to the cardboard. Then I taped the three card board
sections in place around the tunnel. Re-installed the carpet and reduced
the heat to the cockpit by at least 50% if not more. ( just when my blower
quit ) I insulated the firewall to the cockpit under the carpet in a
similar fashion, but did nothing under the floor carpets. (yet?) I did not
notice a significant reduction in noise. This is not a sound insulator. I
suppose it's available in the building supply places. I don't know the
price. (significantly cheaper than the 4' x 6' section I contemplated buying
from the catalog )

Just thought to pass on a tip.
