I my view,half quart/litre ph is very good-I've not seen better;one
quart fine,and the the official limit that is acceptable to Vedenyeev is
three litres an hour!!!

Mark,
Sounds like a very interesting mod.
Does Bill Blackwell have a website??

My M-14p is using about 1 1/2 qts per hour. Oil consumption has gone up
since new but that was 1500 hours ago.. All rings (except # 9) have over
1000 hours on them. Low cylinder is 72/80. I use nothing but 60wt detergent
oil and 50wt when it gets a little cooler. Have 10 micron filter which is
still very clean (no metal) after each change. I run cruise at 2000
rpm/28mp and acro at 2400 rpm and 32-33 mp. I have the top end of the governor
set at 2850. Temp is usually at 150 to 160C cylinders and oil temp out is
around 100C.
I am planning to go to gap less rings, flat head close tolerance pistons
and perhaps with "O" ring valve seals. Because of the high time on the
bottom end, I don't like the idea of boosting up the horsepower to God knows
what. Besides money IS the constrainting factor. Hopefully if my retirement
fund turn around enough to make my wife feel comfortable, I hope to do
this later this year. Maybe this "top" over haul, will see me though my old
age. :))
BTW, Back from Sun&Fun. Three years ago was the "Hay Year". Last year
was the "Mud Year". This year will be known as the "Soot Year". The airport
authority at LAL decided to burn the aircraft tiedown area after cutting it
and not finding any one to bale the left over hay. Of course the rains
did not come! The result was blowing black soot everywhere. Just walking
though it kicked up black clouds. People looked like Al Jolson look a-
likes. I caught sight of the T-6 guys right after starting engine for the show.
It looked like all of them had way over rich mixtures. A number of WBs
left early because of it. As it was the count from last year was down 30%.
Saturday's crowed was OK but the earlier part of the week was way way off.
RPA again put up the most A/C. but our numbers were way down too. The
most we put up on one day was 8. The last day we put up 6 but that included 2
orphaned T-34 guys. The T-6 guys were lucky to get 4 for the "Missing
Man" salute.
Boggs has tighten up the show and run-in lines. It requires some very
precise flying on the part of the lead. Flying with my canopy open, I had the
"experience" on landing of feeling the blast and the HEAT, when "Dynamite"
set off a charge between me and a Wildcat flat out and level with me, on a
"strafing" pattern. Great fun.

If the engine is burning anything over 1L an hour isn't that something to b
e concerned about? Our machine=2C in cruise config is using about .700L an
hour (700mm and70%).
I found that 10L on the mark was ideal for akro although the book says taht
is a min=2C and generally ran up to 12L for cross country.

I don't think Bill has a web site believe it or not.- I do think that he
did some advertising in a recent Red Star newsletter though... you might as
k a member.- He is also offering a new exhaust design that basically is d
esigned around single tube header//collector concept from race cars.- In
fact I think his whole approach began from that starting point.- I have s
ome experience with drag racing engines and his mods have the look and feel
of some of the same things done to typical race engines.- The Russians u
sed loose tolerances with rings that hopefully would expand and seal once h
ot.- They do actually.- Bill's approach was to use a slightly higher co
mpression piston, which I think was something around 8.4:1 or so, then re-m
achine the valve guides, then use closer tolerance pistons with the gapless
rings.- Just with the pistons, you could probably expect a 20 HP or more
gain on a M-14PF.- With the new exhaust system, I would expect he is
getting somewhere near 430 HP or so out of a M-14PF.- Tom Johnson also m
oved his oil cooler to the wing root.- His airplane is simply over the to
p.- His engine was a prototype for Bill's mods, he has the MT FW-190 blad
ed prop, he had CUSTOM tube headers installed and they are simply just GORG
EOUS.- I have no idea what his engine puts out, but it's dramatic.- Tom
is good friends with Bill Blackwell... suggest you talk to him personally.

Andrew=2C read what Richard Goode said. I am not an engine expert. I have
a fair amount of experience as does a lot of other people here. Richard i
s ....to me .....the man who knows every detail of what the Russians themse

over 1L/hr is fine. I would trust anything he says.
I agree on your engine oil levels!

I found that 10L on the mark was ideal for akro although the book says taht

| Subject: | Re: SNF Attendance |
For me its a time to get to see old friends once again. I look passed th
e
culture its leadership that seems to use the good fellowship of the
aviation community, for some kind of financial gain. I go there for my
self - not
them. I do get to see the latest stuff that's coming on line and buy som
e
neat stuff at show prices. One of the things I saw this year was a flyin
g
motorcycle. Folding wings, telescoping tail, and ducted fan engine 2
seater. I bet it works. I also saw a new kit glass job that will fly co
ast
to coast at 200mph. Plus getting a close up look at the different LSA
stuff. Also I get to hobnob with my Aeroshell buddies. If you think our
debriefs are brutal - you should set in on theirs!
Flying the show - to me - takes a certain discipline to pull it off withou
t
someone getting hurt. Not everyone does it well. Some get to
intimidated to even try. Others are quickly asked to stand down. Yes so
me of the
big iron guys fuckup big time, in tune with their egos. IE The Wild Cat
pilot who pitched up into our altitude instead of level as instructed.
Of
course he than proceeded to lose her and ground loop her into the grass
on the
same landing. He wasn't seen the rest of show. While the show might be
great for your ego, there is no place in the show for egos to go unbounde
d.
It will be a long time before I see them paying for all your expenses to
go to the show. For none of us lowly formation warbird guys, have the
crowed appeal that the acro, military jets, and honest to God acro teams
do.
I believe the perception of a poor economy (real or not) didn't help.
Also the show up at Cecil in honor of Allen cause a number of guys to have
to
make a choice of either that or SnF. Plus 5 of our number decided to do
the Bahamas and were just to popped to pop by the time they arrived there.
So it goes.

My M-14p is using about 1 1/2 qts per hour. Oil consumption has gone up
since new but that was 1500 hours ago.. All rings (except # 9) have over
1000 hours on them. Low cylinder is 72/80. I use nothing but 60wt deter
gent
oil and 50wt when it gets a little cooler. Have 10 micron filter which
is
still very clean (no metal) after each change. I run cruise at 2000
rpm/28mp and acro at 2400 rpm and 32-33 mp. I have the top end of the go
vernor
set at 2850. Temp is usually at 150 to 160C cylinders and oil temp out
is
around 100C.
I am planning to go to gap less rings, flat head close tolerance pistons
and perhaps with "O" ring valve seals. Because of the high time on the
bottom end, I don't like the idea of boosting up the horsepower to God kno
ws
what. Besides money IS the constrainting factor. Hopefully if my retire
ment
fund turn around enough to make my wife feel comfortable, I hope to do
this later this year. Maybe this "top" over haul, will see me though my
old
age. :))
BTW, Back from Sun&Fun. Three years ago was the "Hay Year". Last year
was the "Mud Year". This year will be known as the "Soot Year". The airp
ort
authority at LAL decided to burn the aircraft tiedown area after cutting
it
and not finding any one to bale the left over hay. Of course the rains
did not come! The result was blowing black soot everywhere. Just walkin
g
though it kicked up black clouds. People looked like Al Jolson look a-
likes. I caught sight of the T-6 guys right after starting engine for th
e show.
It looked like all of them had way over rich mixtures. A number of WBs
left early because of it. As it was the count from last year was down 30
%.
Saturday's crowed was OK but the earlier part of the week was way way of
f.
RPA again put up the most A/C. but our numbers were way down too. The
most we put up on one day was 8. The last day we put up 6 but that inclu
ded 2
orphaned T-34 guys. The T-6 guys were lucky to get 4 for the "Missing
Man" salute.
Boggs has tighten up the show and run-in lines. It requires some very
precise flying on the part of the lead. Flying with my canopy open, I ha
d the
"experience" on landing of feeling the blast and the HEAT, when "Dynamite
"
set off a charge between me and a Wildcat flat out and level with me, on
a
"strafing" pattern. Great fun.

Curious about my oil consumption and how it relates to the group as a
whole. I'm typically burning a little less than a quart an hour in my Ho
usai.
About 250 hours since first overhaul. Occasionally more. How about you
?
