I received some good advice a few days ago on landing techniques for my model IV, so I thoughtI would pass this by you also. I built my Fox and it's net weight is 575 lbs. The warp drive prop pitch is set at 17 degrees. Max rpm it will achieve for takeoff is 4900, uncalibrated. It climbs like a rocket and cruise speed at 4200 rpms is 95 mph. My worry is the engine oil temp runs in the low yellow at around 255 degrees while the water temp is only about 150 degrees. Oil pressure levels off at around 30 psi after engine warms up. The engine is a NSI version with approx 1000 hrs. It was taken out of another kitfox that met a deer and I installed it in mine. Compresssions are all 175. Are these parameters normal for my setup?

Extremely lightly built with a suberu engine. must be near a record lite weight with that combo.

I think I would add some capacity to the oil system with a larger filter or better yet an oil cooler.

150F = 65C is a bit cool, 90C = 194F would be better.
Oil little to warm with 124C=255F
My SEAT have 90C/194F as normal marking and 130C/266F as max on water, and 100C/212F as normal and 150C/302F as max on oil, a little warmer then usual on old engines.
If you don't have you can use a water cooled oil cooler that sits under the oilfilter that will cool oil and warm water.

Ps. a woman entered the Autoshop, and said; I want 710 !
The clerk asked, What is that? She said it says 710 on the filler on the top of engine...

Exactly what I was thinking...I'd like to see one of my ex-wives on
that scale...I'd probably still be with her.

275 0n the right main, 265 on the left, and only 35 on the tail and that's with the battery and elt mounted in the back. maybe that's why I have trouble getting the tail down.

That is really hard to believe. Mine is 301, 306, and 43, and that's
with a Jabiru 2200, my battery is on the firewall, and my ELT is just
behind the baggage sack. I did however, airfoil my vertical fin and
rudder, so that added weight. When I first came aboard this list, I was
told about the Subaru: "they are heavy...avoid at all costs". So
forgive me my skepticism...what model do you have? Mine is a IV. I had
mine weighed by an EAA tech, with aircraft scales rented from an
avionics shop and calibrated on the spot.
Not doubting you, just find it hard to swallow. : )

I would say your scales were more accurate than mine but not by that much. The only things missing off the plane were the wood farings for the wing and landing gear struts. Instruments are basic, no radios or wheel pants. It is a 1050 and not a 1200. I really only entered the weight in the tread so someone could tell me if my speed/rpm/pitch relationship sounded right. By the way, I like the oil cooler idea for the oil temp but after looking on the internet at the oil filter adapter, I don't think I could get it on because you can't hardly get a filter on it now due to clearance with the motor mount.

My Soob has a remote oil filter adapter that allows
attachment of the filter and cooler where you can get
air to them and do easier maintenance. Jegs and other
high end auto parts suppliers should have the parts
for you. I'd definately get the oil temps down and
pressure up to more around 40-50 psi in flight.

Yes, those liittle EA81's go eh, I have a turbo EFI 81. 17.5deg on the prop
(WDrive) and at best rate of climb speed 1700fpm with 1/2 tanks and just me
(80kgs) on board. All the speedster bits and I get 100kts cruise at 4100. If
you can get your oil timp down to 90c the pressure should be 40+. I have a
water to oil heat exchanger, keeps the delta close. Could work for you with
high oil temp and low water.

Yes, I'm blown away as to how well my wee beast goes and checked ASI with

you turbo-ed?

Mic, my S5 is 885 empty and I cruise about 108 ias at 3900 rpm at 22" MP and
4gph fuel flow. I do have the NSI CAP prop which probably accounts for a
lot of the performance and also lots of fairings including fuel caps and
radiator and wheels.
Oil/coolant temp on an 80 degree day are generally around 200f.
What type of Soob are you running? Perhaps you don't have enough prop
pitch? Normal aspirated or turbo?

Your empty weight is about the same as mine but I bet you do not have enough
pitch in the prop. When I first flew mine I had 11 deg in the prop and got
about the same # you have then I increased it to 17 1/2 and got a cruise in
the 90's. What pitch are you using?

You will find that the turbo sort of takes the place of an adjustable prop.
With your adjustable you are aiming to keep the RPM in the top of the Tq
curve, with a correctly matched turbo you have a nice wide flat curve, thus
enabling operation near the top over a broad range. I also have an
intercooler as well which further helps.~j~

Mic, my S5 is 885 empty and I cruise about 108 ias at 3900 rpm at 22" MP and
4gph fuel flow. I do have the NSI CAP prop which probably accounts for a
lot of the performance and also lots of fairings including fuel caps and
radiator and wheels.
Oil/coolant temp on an 80 degree day are generally around 200f.
What type of Soob are you running? Perhaps you don't have enough prop
pitch? Normal aspirated or turbo?
