Aircraft: Giles 202
Engine: AEIO-360-EXP Lycon 2..???HP
Exhaust Systems: Sky Dinamics 4 into 1
Purpose for the wrap: Lower Oil Temperature and reduce radiant heat into intake pipes. Intended Material Use: Exhaust Wrap sold by Spruce

Any personal comments or opinions based on actual experience in regards to Wrapping your aircaft exhaust pipe? Not wrapping the entire pipe...just from the Cylinder all the way down to where it will not radiate into engine case and intake pipes.

I have used wrapping extensively in the past in my race bikes and liked the performance gain and long term result results. If I google the subject, I already got all the internet experts and weekend warriors speaking against!

While on the subject...wrapping the intake pipes with Aluminized Heat Barrier in order to divert some of the radiant heat and keep the intake air cooler. According to manufacturer Aluminized Heat Barrier reflects 2000F

Sharing my finding with those 33 viewers who decided to open my post...........

Great Exchange of emails with Marshall Murray from http://www.skydynamics.com in regards to my question. I have used skydinamics exhaust on both my S2B and Giles 202. Great product, great people to deal with!


For the exhaust wrapp as I was told: Adds weight, traps moisture...Not enough positives that outweigh the negatives. Use it only as a last resort to cure temperature problems. There is such a large volume of air passing through the cowling while in flight that little to no heat is being exchanged from the exhaust to the intake.

Same for using aluminum barrier in the intake pipes to divert radiant heat: The majority of the heat being imposed onto the intake air is coming from the sump (hot oil). To the point that I will be trapping heat in the intake tubes by wrapping them if wrapped w/ barrier. The natural airflow cooling effect will be gone.

Hope this helps others with the same itch of trying to gain a few ponies and lower ops temps... There are solutions to my quest and as usual they cost $,$$$.$$
