| Subject: | Re: louvers on Glasair III |
The rear two - 3 and 4. Pretty common. They are not bad in cruise but
here in Texas, when it's hot, the cylinders get hotter than I'd like but
still within limits. I just need to do a cruise climb and not a more
aggressive climb.

By powder coating and having an additional interior ceramic heat treatment
on the exhaust system you can lower bottom end exhaust temperatures up to
15 degrees. That bottom engine high temperature is absorbed by the oil
coolers' body, oil lines, oil sump and intake systems. After the above was
done to a home base aircraft, the aircraft's oil became so cool the mechanic
had to install a pilot operated gate to get the oil up to temperature!!.
