Hi Jason,
Great to hear first flight was all you could want - well,
maybe with the exception of the temps. Not unusually for a first flight
(especially in Texas Summer {:>)). I fly with a 24-27 psi radiator cap
and seldom have ever had water push pass the cap. Also, make certain
your coolant system is full of coolant. As has been reported even with the
Rx-7, its not unusually to find air entrapped after changing coolant. I
normally run my engine up to 5000 rpm about 3 times after a coolant change
before most of the entrapped air is removed.
Most of us have found that having the muffler under the
cowl simply radiates too much heat and contributes significant to under cowl
temps. I believe that Tracy's experience with the Flow Master muffler
makes it a leading contender. Effective, light weight and
aerodynamic.
Keep us posted on progress and again,
Congratulations
Ed

Flight!!!
Well I can breathe again!
On Memorial Day, N821GL took to
the sky. What an incredible experience!
Water temp got up to 220 and oil
peaked at 208 so there is room for improvement. I was throttled back most of
the flight so a little more speed might help. I did push it up to 6200 and 140
MPH for a short bit. Water pressure peaked at 23 psi, so I cut the flight
short.
On post flight I found that water
was being pushed past the cap on the radiator. And the can muffler radiates
WAY to much heat. So it's on to rev B. Closing the radiator cap up and
constructing a new exhaust system.
I will post some pictures soon.
Thanks to all that have paved the way!
Thanks,
Jason
