Exhaust/Radiator hose heat barrier
Posted: Sat Feb 18, 2012 1:43 pm
I've run up against another problem with my V8 installation. The exhaust is
only a couple of inches away from the radiator hoses for a couple of inches.
I'm going to have to build in a heat barrier of some sort. I can't put
cooling air in the area because that would raise the pressure on the exhaust
side of the radiator and inhibit airflow through the radiator. I thought
I'd solicit ideas from the builder's list about what kind of barrier.
Exhaust wrap, coatings, etc. are obvious methods. I wonder what other ideas
might pop up from you learned folks. For the sake of simplicity let's
assume I can't reroute the exhaust (i.e. do away with my headers and use
short stacks like P51 replicas) or relocate the radiator (my radiator
installation is beautiful if I do say so myself - please don't make me move
it!). It seems like exhaust wraps would be superior in heat reduction
compared to coatings, but I'm just guessing. Anybody know? My exhaust is
so simple (one 90 degree elbow off the header collector and out the lower
sides of the cowl) I'm not concerned about accelerated deterioration of the
exhaust due to using a wrap. It'll still likely give me years of flying
before needing replacement and then it'll be dirt cheap and easy to replace.
