| Subject: | Flight Test for a Remote Oil Filter Kit on the Stratus Subaru |
Hi guys,
Sept 10 After a Hy-Vee lunch with the guys, I went to the hangar and did a
thorough preflight, did take a full 5 quarts to top oil off before startup.
The Subaru fired up immediately and I taxied out. Oil temps began at 60
p.s.i. and when warmed went down to 45 p.s.i. Tower cleared me for 10. The
lift off was trim-adjusted with no perceptible feel for the weight change up
front. I flew south of the control zone to the designated "practice area.
Oil temps at 3000 feet reached 228 degrees at 4300 rpm and I progressively
brought up the power in 100 rpm increments every 8 minutes or so. CHTs
stayed 190 to 200 degrees, EGTs 1380, Coolant 200 and when rpms reached 5100
and airspeed at 128 mph, oil temps never went over 233 degrees. All other
temps stayed well in the green. The remote oil filter kit resolved the max
temp issues. I stayed on an east west track until I was satisfied that the
engine was happy within its full range of operation and then headed back to
Moline. Descending at 125 into the pattern was easy, the landing was smooth
and I taxied back to the south tees with 175 hours on the engine. The cowl
was unbuttoned, the engine was drip-free and oil hoses stayed where they'd
been clamped. Pictures are added
<http://www.macsmachine.com/html/subaruengine.htm> to the bottom of my
engine page that shows the components and installation in greater detail.
Very satisfied with this modification! Data was entered into the logs.

Thanks for posting Larry. What would you say the difference is in oil
temp - what would the oil temp have been below without the remote filter?

Hi Gary,
>From my journal, I'd earlier posted;
Note: I often think an oil cooler might be a worthwhile addition.
I had concern for oil temps that ran as high as 235 degrees F. The manual
states 260 is the max oil temp permitted. Flying at 130 mph at 5200 rpm on a
hot day of more than 90-degrees, engine oil will eventually reach 250
degrees (my warning set-point on the EIS) so I do back off to 4600 rpm and
cruise at 115 to 120 mph. Oil temps will then stay near 235.

Was it also 90+ degrees? If so, you went from about 250 to 233 degrees
at around 130 mph and 5200 rpm. That's much more significant than I
would have guessed for just a remote filter. I like where you mounted
it, perfect spot with plenty of room and great airflow. Nice work, thanks.

Subaru
Both days were in the mid-80s. I'm sure the temps were 4 or 5 degrees
cooler
Yesterday, so the advantage was realistically more like 10-degrees or
better.
Sure is easier to access. I'll have to watch the bracket for any signs of
fatigue.
It feels solid, but must stay that way to avoid cracking anything, lugs etc.
I designed
the piece so the small rod welds will be the first to show fatigue, should
that occur.
