[Healeys] End of an Era - Route 66 trip - car preparation

[richard mayor]

I insulated the footwells from the engine side with an adhesive heat barrier material used in race cars.  Sorry, can’t tell you the manufacturer.  I made sure there were no cracks, gaps or holes. Any firewall gaps where cables or hoses go through  were sealed with dum-dum (3 M black rope caulk).  I used Hush Mat on the inside of my foot well.  I put the Hush Mat all across the top of the inside of the firewall where that strip of tar paper is applied and I also covered the air box that goes across the inside of the firewall.

 I eliminated the two piece metal tunnel and tunnel extension and used a BJ8 fiberglass tunnel which makes a really good seal in that area. Finally, I put side vents in my fenders that allows the heat to flow out and eliminates that high pressure area in the transmission tunnel.  I have no insulation, inside or out, and no carpeting  on my BJ8 tunnel.  It gets fairly warm on hot days but it does not get hot. 

I can drive my car in 90 degree weather and my feet stay cool.
