Help ! SMALL Radial engine

Ok, here goes...

About 2 years ago I had a chance to buy some small radial engines at a
car show, there were perhaps 25-36 inches accross, I cant remeber, I
had a chance to buy em at $40 each and there were 10 or so in various
states of disrepair, but since I had spent all my money alloted by the
wife and I had no conciveable use for them I forgot about it. They
were I belive WWII vintage used to power either compressors or
generators. I want to say they were in the 20-40 HP range (very fuzzy
memory except what they looked like being radials and all) I'm pretty
sure they were 5 cylinders.

Now I have a project I absolutley need one for, but I cant find any
info on what they were to start looking.

Any info posted would be greatly appreciated, manufacturer(s), tech
specs, where to find one (hey maybe you've got one collecting dust) I
would like a few of the same or close (parts interchange) model.

I apologize for the cross posting but these are the only NG's I
thought I may find info in.

Also, since I have never had a radial, started, run or anything other
than looked at one, I am curious, the project I am building is not an
aircraft so no need to worry about me strappin this on the back of my
bensen and ending up splattered (I had a friend I sold an old solar
APU turbine, he was worried I may try to do exactly that with the
turbine I would like to mount the engine parallel to the frame of
the vehicle, the problem is that it will reduce the airflow to the
back 2 cylinders, since this engine I am looking for was built for
stationary use is this going to be a problem ? I can if I have to
mount it perpindiculay (as a radial would be on a plane) but would
preffer not to, If I have to does anyone have any idea of the torque
from the reciprocating mass from this type of engine (whatever it is)

Something in my memory keeps wanting to say it was part of an APU for
a WWII vintage U.S. bomber, it was most certainly of U.S. manufacture.

Many Thanks

Well, about four years back I was at J-Bird in Kewaskum Wisconsin. I seem
to recall they had a radial engine for sale (and a few other oddities).
Perhaps they could help?

Radial engines were also used in some tanks and smaller scout cars.



Does it have to be a radial ? Have you thought of a mid sized
motorcycle engine ?



I have no idea what your project is, but if possible, you'll get much
better performance, spares, support and loose change from the likes of a GS
650 aircooled 4 cylinder as opposed to a 60 year old antique.

You sure they weren't engine/aircompressor?
I've got one of those. It is a 6 cylinder radial, runs off 3 and
compresses with 3. They were made by Ingersol Rand. and are about the
size you describe. It runs with crankshaft vertical.

What you're describing might be an Ingersol-Rand model 3-R-36. They are
actually a 3cyl engine, driving a 3cyl air compressor. I have a few
pictures of one that I saw in New Mexico if you're interested. If so,
E-mail me at the hotmail account.

Is that the gadget you are referring to?

Sounds like the Lawrence radial engines used as APUs on B-29s.

Very interesting James. Thanks for posting this.

Well thanks for all the responses.

Someone mailed this to me so I thought I would post it here in case
anyone else needed to know it, at least get it archived on google.

5-cylinder B-75 Lawrence radial 37.5 HP,

Not much more info but a search on good ole google groups found me a
little more info, This seems to be the beast Im looking for, twin
mags, which I remeber now,

That Ingersol Rand compressor is pretty cool though, too bad its a not
JUST and engine (albeit 1 cylinder too many

Thanks

Chris
