[Healeys] Heat management

[Randy Hicks]

I just wrapped my downpipes with a high tech wrap in hopes of cutting down on
rough idle (vapor lock or gas getting to hot???) at high outside temps and in
stop & go traffic.

Did you notice any difference in this area?

I'm driving the BJ8 to AZ next month and will update.

discussed it before--and there seems to be some anecdotal, positive
results--but does anybody have any definitive info to add?

hot to pistol hot--circumstantial evidence that more heat is being moved away
from the engine compartment. I can't say I saw a measurable decrease in
coolant temp, but unless you do before/after testing under identical ambient
conditions it's going to be subjective at best.
