Best... Steve

Alex,
 
At 10,000 feet you lose about 5 psi of atmosphere 
making your 14 psi cap a 9 psi cap absolute pressure.

Hi 
Chuck-
Thanks for the kind 
words- I have spoken to the Swings about their experience with the Subaru- they 
were using the stock ECU which is not suitable for aircraft use in my opinion- 
Tracy Crooks equipment is purpose built, simple and does a great job.  I 
have an oil cooler on the Tranny- it is mounted down stream of the Engine oil 
cooler, although I might swap positions if I find that the engine cooler is just 
cooking the tranny cooler-  see video-just figured that it was more 
important to have cool engine oil than PSRU oil- I have a temp sensor on the 
PSRU to keep an eye on things though. I have heard that the Mazda engines are 
notoriously difficult to keep cool on the ground, and their high RPM make life 
difficult on the gear box too. Right now I am using water/glycol but might go 
with the non-aqueous coolants that some folks are running to avoid pressure 
problems in the system- I do have a 14 psi cap on there and a pressure sensor 
for the coolant system so I can keep an eye on things.  Will be doing a lot 
of extended high power ground testing before any flying is considered for 
sure.
I have a few things to 
get done before I get flying- namely get my home brewed retract panel working, 
get my 2 battery/2 alternator electrical system connected up just right, and buy 
a flight prop- so probably will not be getting airborne until at least the end 
of the summer (with the recession and all) 
 
Alex

I went with the almost Subaru 6, but 
Dwayne told me a few stories about their exciting experiences when it went into 
"limp home mode". Sounds like you've got it handled with Tracy's system. I had 
a turbo-Mazda rotary 20B (3 rotor) which was a problem due to excessive heat and 
gearbox reliability. I ended up with more radiators for both the engine and 
gearbox. You might want to have an oil temp gauge on the outlet of the 
gearbox to make sure it stays under 220F. I hope you don't get engine overtemp 
problems on the first flight like I did, but be ready to get back on the ground 
if you do. Al Gietzen (Mazda 20B) is the expert on oil/water cooling for 
non-AC engines if you need a resource. 

 

Looks like a beautiful installation 
and we'll be watching for you to take that first flight. Good 
luck.

Well, after a lot of additional 
work- and parts fabrication,  I replaced my previous engine control unit 
(supplied by our friends at Crossflow) with an excellent ECU from Tracy Crook / 
Real World Solutions- I can recommend him highly- he was always available to 
help and re-program the unit to make it work perfectly- I have a new video 
up:  http://www.youtube.com/watch?v=gW1YtHq9ZtY 
– I still need to do the fine tuning programming, but should be taxi testing in 
a month if I can get out to the hanger more that a couple of hours a week…….. 
now just need to save up for that Vesta prop I have been 
eyeing……
