Heah
Rusty,
You've
been reading my mail or riding in my airplane.
My
reflection over time is the same as yours. My engine is not develping the
power that Tracy and others are seeing.
Well,
Duh! You and I have failed to get the power because we have
experimented with our own solutions.
I give
up! I need a well tuned induction system rather than my expedient
experiment.....ya gotta laugh here...
The
plugs might need changing, but that's not the BIG solution we need.
I
notice that there is the old theme of induction questions and interest coming up
again. (true, I am raising it too) and perhaps the time is right to join
forces and come up with a bolt solution that will be available for
all.
It
seems to me that an EDDIE target of 5500-6000rpm could be cobbled into a
manifold that would be effective in the RV's and the Glastar and the
Canards. Perhaps I'm dreaming, but it seems all the talent is
available. (not one single person mind you) and, if we can figure out how to
actually have a joint effort that produces a working solution, beneficial
to all, then we all leaped ahead in our experimentation..
I will
now climb down from my Epulpit.
Happy
Sunday to all,
Tommy

Great flight report Rusty. You sound a little
disappointed.
I AM disappointed in the current
performance. My friends RV-3 with a 160 HP Lycoming is
nearly doubling my climb rate, with an almost identical prop. At
least I have proof that my engine isn't producing the power that Tracy's
is, so I just need to get to work on finding out why.
Step one will be a simple thing, changing
plugs. I now have about 30 or so hours on the engine, mostly with 100
LL. I've felt a couple of times in the last two runs, where full
throttle seemed to go over rich, and leaning the mixture a little seemed
to help. I'm wondering if this might be Ed's plug
sag???
Step two will be a new intake, but I'm
completely undecided as to how I'll proceed.
Ed, you may not have a direct answer to
this, but how about taking a SWAG. How
much rpm would you expect to gain by going from
a typical short intake, to a fairly well tuned intake? Are we
talking hundreds, or maybe 50?
It was, after all, a FLIGHT report. If you would prefer
you can fiberglass my cowl and I will do your flight testing
:-)
Can I have about a
nanosecond to think this over :-)
Look at it this way. You get to keep flying until you get around to
building a new intake at your leisure. I’m sure you’ll get there.
There's always at least one optimist
in the group :-)
Thanks for the vote of confidence,
but the problem is that I'll be obsessed with making this perform better, and
I'll spend all my time working on it, and not flying it. This isn't bad,
since I need something to tinker with, but it sure won't get the test hours
flown off anytime soon.

empty)
