Hi, Herb....I am still playing with it on the
ground. I did a couple of aborted takeoffs yesterday, and it seemed to be
running fine. Today I ran it with the top cowling off to see how many
rpm's I could get with unrestricted airflow into the TWM throttlebody. Today it
only went to 5250 rpm's static. Last week I had it up to 5600 rpm's
static. By the time I was starting to play with the mixture settings, the
temps were getting too hot, so I shut it down for the day. Hopefully
tomorrow I will get to do it again, and this time I will have more time to
adjust prior to overheating temps are reached.
The engine is
running very smoothly, with no hesitation anywhere from idle (800 rpm) to full
throttle (5250 rpm's). I finished the ram air scoop on the cowling to
bring inflight ram air to the throttlebody intake. I am also making an
aluminum scoop that bolts to the throttlebody, which is kind of like a short
periscope that protrudes into the fiberglass ram air intake scoop I just made
(on the cowling). That way, any incoming air has nowhere else to go but to feed
the throttlebody. It is all fabricated, I just need to get it welded.( I do not
want any screws or nuts on this intake that might possibly come loose and be
ingested into the engine). Call me chicken, I don't care.
I also purchased an MS
HA-6 sidedraft carburetor. I am going to make an intake plenum for it similar to
Ron Gowan's rotary powered LongEZ system, except that the intake runners will be
shorter, since his is mounted plugs up, and mine is mounted oil pan down.
Haven't commited to the carburetor yet, as I am still giving the ECU one last
chance to prove it's virtues.
The HA-6 carb has
manual mixture control and would eliminate a lot of electrical current demand on
my system if I dump the two high pressure fuel pumps, electrically fired
injectors, etc. I could also dump the controversial fuel return
line, vented sump tank, etc, etc. The down side is I will have to
hook up a mixture control lever and supply carb heat. The carb's close
proximity to the exhaust makes carb heat provision very easy, of course.
Decisions, decisions. Guess I shouldn't complain as I do have a good
flying canard aircraft with which I get to make these decisions....only the
engine/fuel system needs more experimentation. Glad it's an experimental,
and I am allowed to experiment.
I also purchased street
ported 4-port turbo engine parts, and an extra 6 port NA engine, so
that I can use two engines to make one street ported 4-port with NA rotors
and housings. On the other hand, if I get my 5600 static rpm's back on my
present 1989 turbo engine (minus turbo), I just might keep and be happy with
what I have on the plane right now. That extra rpm would probably put me
over 200 mph, and I would be quite satisfied with that. I could always
sell what I don't need. Paul, sorry I bored you to death,
Conner

I just check in to
see if Paul is flying his Hangar Que – uh, ‘scuse me, Speed Queen
againJ. You need to get
that bird going and fly the time off, Paul, so you can bring it to
S&F. Herb Sanders Before you put me in
my place, my Velocity is not even a hangar queen yet, it is still a SQ (shop
queen).

acetone ?
The last email I received was at
9:46 PM yesterday and was about acetone; either someone somewhere spilled some
of it on our server; or this list has gone quiet, all of a sudden. If I have
offended any of you out there to the point you have simply cut me off all this
good info, I apologize, sincerely, no less. <g> THIS IS A
TEST.
