My heat shield is a stainless steel sheet shaped to fit the TR3, obtained from British Parts Northwest in Dayton OR.
Thanks for all the suggestions and advice guy's. I have until April to figure out what I'm going to do, and it probably won't be a single solution.
My car is happy cruising, even on the highway, but doesn't cope at all well with slow moving or stopped traffic, and less well when it is hot out. I keep it in a garage in Boston and encounter traffic whenever I collect or return it. It usually gets very warm very quickly in traffic and often boils or poops out (vapor lock). I'd like to improve this next year.
