You
might be surprised to see what you are doing to your engine if you
saw it
on the instrumented engine test stand. Since I have seen the
results
of your methods, I seriously recommend that you consider
altering your
methods. Your engine will thank you. Others who have
used the
same methods as you have been using have been alarmed at what
they SEE
with their own eyes when this is done on an instrumented
engine. You
are placing the engine under very high internal cylinder
pressures and the
CHTs are higher than I would want to see during
climb. Taking off with
less than full power places MORE stress on the
engine than full power with
adequate FF. This is easily measurable and
is frequently quite a
surprise to those who see it.
Of course, you may ignore this
recommendation.
Walter,
You have got to stop mixing up messages. I gave no information on how
I take off and climb - But, here it is:
If I am not at a high altitude airport:
Full rich, everything firewalled, 15.4 gph, climb out at 135-140 Kts (well
above Vx or Vy), After I am above 700 AGL, prop to 2600.
After about 3500 MSL, WOT, 2600 rpm, start leaning to 120 ROP and continue
to do this thru the climb.
After reaching cruise altitude, I may or may not reduce the throttle
depending on how high I am. Level out and await estimated IAS cruise speed
while ram air builds in induction and injectors. Prop back to 2510 (it
sounds like a hummer). Adjust mixture either 100 ROP or 30 LOP,
depending.
If I am racing, probably at no more than 3000 MSL, 2710 rpm, WOT, maybe
about 13.5 to 14.2 gph, depending...
I am not ignoring whatever you are recommending...................
