Before that, the temps would climb up, what I think is too high,
especially the oil.
That's part of the point. Maybe you're expecting temps to be lower than they
need to be. Also - how accurately is you're gauge calibrated? (I calibrated
mine with hot wax, but I'm still not sure I really trust it within 10
degrees or so.) I'm looking forward to getting my EM2, then I'll know better
whats going on. So far though, I think I'm within acceptible limits - I'm
not loosing any coolant and the engine keeps on running :)
I've been flying only in the mornings when the temperature is
<80. The last
flight the coolant was OK (about 200) but in just climbing to
1500' AGL the
oil was 220.
Last time I flew I was getting a stabalized 205/210 in the climb
(coolant/oil). When I leveled off at 5000 it settled down to 185. At 11000
it was lower until I opened the throttle, then it stabalized at 185.
powering back to about 4100 RPM's, the oil dropped to about 210. OAT for
that flight was right at 80 F.
I'd be interested to know if others see that as acceptible.
At level flight, when I add power, the temperatures start climbing.
OK, but do they stabalize, or didnt you wait long enough?
After adding the vortex generators the temperatures were definitely lower
oil 220 down from 240, and coolant 200 down from 210-215. So they did
definitely help.
Yea - 240 oil is too high. Under what conditions were you getting that? Full
throttle climb? I havent tried that yet.
I am curious about what your temperatures are running. What do you see in
climb ? and what do you see in cruise ?
Climb - 205/200, 1400 EGT, 100kts, 1000fpm on a 90F day.
Cruise - 185/190, 1300 EGT, 178kts, 5150 rpm, 38 MAP 11,000 ft.
I've been looking at
220 oil and 215 coolant as the redline.
Me too, but I think you could try living within these numbers. You're really
not that far off, and dumping heat from the turbo or just throttling back,
better might be much more efficient than stuffing more air in with scoops,
just so you can climb faster.
Maybe I'm wrong.
Me too. :)
I'd be interested in other perspectives on this one.
