Header heat wrapping

[grybrd123]

After I got my Superformance Daytona coupe, I found that the amount of heat in the engine compartment was unacceptable - it made the cabin too hot and heated up all the engine compartment components to way too hot. I was worried that they might actually melt, burn, or just plain fail on the road. The first thing I did was reverse the rotation direction of the under engine fans to blow up and help the air rise, rather than down against the normal air flow; it helped, but not a whole lot. Then last fall, I had my headers heat wrapped from the heads to the bottom of the collectors where they go through the body lower panels. It made a HUGE difference (cut header temps in half, from 600 to 300 degrees!) and I've been very happy with it until now.

Today I heard that it may cause the headers themselves to fail, and worse, it may damage the cylinder heads eventually. I understand that the heat has to go somewhere, and the heat wrap undoubtedly keeps the headers much hotter than they were when unwrapped, but I hadn't heard that it would cause serious mechanical problems.

So, does anyone out there have experience with this issue, and what are the heat-reducing solutions other folks have come up with?

Looking forward to hearing from (I hope) lots of Superformance coupe owners! Sign me confused
