Harley motor in a homebuilt?

Couldn't find any specs on the engine other than the torque at 3000 RPM,
and the Harley web site, like the hog-air web site, was kind of a pain
to navigate.

Any idea if they have the power curve on line?

thanks

There's a "list of verified horsepower figures for a variety of the Twin
Cam 88 and 95 CID Engines" at
http://www.nightrider.com/biketech/hplist_twin_cam.htm

If you drop down to the first 68 hp motor 88 CID engine listed, you can
click on it and get a dyno chart at
http://www.nightrider.com/biketech/dyno_sheets/max_green_tcdyno.jpg

Just looked up what the Harley website says about torque at 3000 RPM;
they claim peak torque of 85 ft-lbs. The dyno chart referenced shows a
peak torque of about 76, maybe 77 ft-lbs at 4000 RPM. Harley's probably
measuring at the crank; the dyno chart is of measurements taken at the
rear wheel.

hope this helps,

Yes that is about right 150-180 Nautical Miles south of Sondre
Stroemfjord.(About 2 hours with a Cessna 172)

I prefer to fly in and out of Greenland using Sonder Stromfjord, as it
os only closed for flight 3-5 days a year.
Narsarsuaq in Southern Greenland is closed far more, maybe 20-30 days
a year.

From one of my friends I have learned that several of the birds have
been found, or I should say, the remains of the birds. I haven't heard
about the Cargo Pod

Happy Flying from a Back Seat pilot ;-)

How far from 'Sendre Stremfjord'? I was flight leader of a flight of
T-33's and all ejected over 'Son-da-strom' (Sp) Air Base 7 December
1969. All survived and one airplane was later found by a trapper on a
frozen lake where it had landed (crashed) and skidded across the lake
to the shore.

Always wondered if they later ever found the bird with the cargo pod
where I had all my civilian clothes and msc? Had a suit I got in Hong
Kong with English material. One of the best fitting suits I ever had
and material was outstanding.. Of course none of those clothes would
fit me now? Time and fat wait for no man G

Wx was 1000 and one in light snow and GCA radio's quit (
Everything outside cockpit was white. Ground, sides of the Fiords,
etc.

Found you on the map. Your about 150 SM south of 'Sondie'.

This guy is building a Replica Airplane, that was originally powered
by a V-Twin. I guess that means, that to be a proper Replica he NEEDS
a V-Twin engine to power it, not anything else, no matter how much
better it is.

I don't know anything about building airplanes, but I did a quick
search on the net to see which Airplanes I could find that was Indian
Powered, and it looks like the Original had around 20HP, so I guess
that he would not need the full performance of the Harley Engine.

Just my 5c.

come up with is a Harley-Davidson.

Do you really want your airplane to go "potato-potato-potato..." ? :-)

And on a more serious note, isn't the 45 degree configuration a lousy design
for vibration (or an excellent one, depending on how you look at it ) ?

In the world of high performance hovercraft, motorcycle engines
have been looked at for years. The only situations where they have
been made to work is where they are installed complete with gearbox
and rigged with a complex chain to belt PSRU. Also, they need to be in
an application where full power is rarely needed. After starring at
these harsh realities, most people choose between 2 stroke power or
Kohler reliability. Or for larger craft, a junkyard 4 cylinder car
engine.

The 172 is hangared at the local airport, together with the Dash 7's
and Sikorsky S-61's(Like the one that picked you up)

Unfortunately I don't have a Pilots License. But a collegue has a
license and goes flying quite often. Also I have been flying very
often with my father for about 25 years, he handled the flying, I
handled the navigation(That was before GPS)

The 172 is operated by the local flying club, biggest problem up here
for private planes is availability of fuel, most airports only have
Jet fuel, as all commercial aircraft up here is Turbine or Jet
powered.

The one that slid in on the ice was a fluke. Bird was trimmed up prior
to ejection and when engine quit a couple of minutes later (ran last
tank dry) it just glided in circles down to the ice.

The cargo pod (only on one bird) was underneath the aircraft and any
wheels up landing, even intentional, would wipe out or tear off.

One pilot broke his elbow on ejection when it hit the canopy rail in
bird after canopy was blown. This was a tight fit with heavy winter
jacket and was a know problem.

Was picked up by a civilian Danish chopper (big 20 passenger +/-
Sikorsky) about an hour after ejection. Flew back to base and was
dark.

We crossed the VOR on a heading of 090 and then ejected. Was told that
by doing this would not land in any open water (short life span at
that time of year).

All in all we were very lucky to make it.

Do you hanger your 172 or tie down and use arctic procedures to start,
etc.?

That's why diesels are so interesting (and the fuel price of course). They
use regular Jet A-1.
