667 cu in 7cyl engine...

[T-56]

Ignoring the obvious (airboat) how could this engine be incoporated into a boat of some kind. Forget about the propeller since it is rotten. Although serious suggestions will be considered, this is ment as a fun thread so let's use our imaginations. :cool:
http://i49.photobucket.com/albums/f283/T-56/DSC00028.jpg
Here's a few specs...
Recomended fuel..........Gasoline w/ an octane rating of 72 or higher
Horsepower.................220
Tourque......................A shitload
Ignition.......................Twin mags
Weight........................300 lbs (give or take, it's very light for it's size)
Oil System...................Dry sump
Diameter......................Less than 4 ft
Redline........................2200 rpm
Watcha thinkin'?

Those engines were in tanks, as well. Didn't tanks go "amphibious" to a degree? How about one of them there "car boat" things?

Yep, that's where this one came from. It's actually a Continental 220 engine.

Makes a cool ceiling fan. :D

How about mounting it horizontaly to some sort of a gear box...kind of like a third member out of a car. Connect the motor to the yoke on the thrid member and use one of the axels/axel tubes as the drive line sort of thing. I think I have been watching Monster Garage too much, I am starting to think rudeamentry :220v:

That's kinda what I was thinking. However, to get anything out of it you would have to attach the crank to an axle and the propshaft to the pinion. I just don't know how well that would live.

This is what the airborne version of the Continental W670 went into:

Or these, mostly...WWII Boeing Stearman Model 75's built in Wichita during the war. Some had Lycomings, a few had Wright engines-

Does the engine still have a data plate on it? If so, tell me what it says. I'd like to know which version of the W670 it is just for fun.

[Sleek-Jet]

You'd want to mount it vertically, then you could do a simple gear reduction from the crank, and it would aid in cooling, thinking v-drive.
One thing about it, that would be the coolest sounding boat on the water... :D
Sleek <----- sitting here making radial engine noises at his desk... ch chug, ch chug, ch chug.... :D

Dude has one on a motorcycle.
I think it is a 985 though.

I saved this pic a couple of weeks ago, just cause it was friggin cool... Same one your talking about?

All kidding aside, this could work. I do not know how good it would look. I am thinking of two options though off of the top of my head. They run 200-300 Hp electric motors with 6-8 groove banded v-belts all of the time on rock crushers, up to 3000 rpm on the motor side. Align the motor where the output shaft is directly parallel over the input shaft on either a jet pump or I/O. Get a couple of balanced 6-8 groove pulleys for the shafts. You would have to incorporate some type of tensioning system for the belts, but you could actually incorporate that into the motor mounts. They also make Z drive gear boxes that you can even overdrive or under drive, depending on your need, but that would be an extra 300 lbs or so and take up even more space. Yu could change your drive ratio with the size (diameter) of pulleys you used. I know the v-belt idea sounds a little out there, but there is no real reason why it could not work. Below is a pic of the kind of belt I am talking about, but with 6 to 8 grooves instead, they are about 6 inches wide. Man that would be cool to see

[Bow Tie Omega]

Here is a pic illustrating what I was thinking, sorry fo lack of artistic talent. Using nice billet parts, it might not look half bad either. That is my 5 cents worth anyways.

[Infomaniac]

Yea that is the one.
This is another one.

Those bikes are NICE!!!! My nuts shrivel just thinking about sitting on one of those :cry:

[T-56]

DaveA, lemme run back to the house right quick and snap a pic of that data plate for ya. :p I really don't remember what it says but get back to me in about 4 months and I'll let you know.
These are really good ideas as far an the beltdrive and i/o applications go. I would have never thought to use a primary on a boat.
Keep 'em comin'!

[Infomaniac]

BTW I worked on Allison T-56 engines in the Navy. E2C Hawkeye. Pretty much the same as the C-130 engine.

"T-56" is my handle from the GMC Syclone forum I joined back in the day since mine had, at the time, the only T-56 tranny w/ a t-case on it. I guess it just stuck. :boxed:

How about this bad boy...4 row 28 cylinder Pratt & Whitney Wasp Major....makes 3500HP @2700 rpm which is almost 7000 ft/# of tq
4,360 cubic inch's...or 71.5L for you ricers...:D 156 cubes a cylinder;)

Arent these aircooled engines? where will all the cooling air come from?

[BrendellaJet]

gotta drive it to keep it cool.

[Infomaniac]

Just for discussion some cooling air would need to be created somehow. Hang it out there for cool factor
You talking bout the 4 row engine?
In the airplane The cylinders are offset to allow air flow. And they have sheet metal baffles around it to force the ram air through the fins.
They arent shown in the pics cuz they aint purdy.

Ahh yes... the first reciprocating engine to achieve the engineering bench mark of 1 hp/lbs... I know where there are a couple DC-7C's sitting if anyone wants one of those behemouths...
You're going to need a bigger boat... :D

[superdave013]

that would be easy. Just hook it up to a Casale V Drive.

[DMOORE]

It could be set vertically, across the boat with a belt drive runnung directly down to a transmission for a v-drive. It would be a fairly simple solution. Imagine a v-drive boat without the motor in it. Lots of room to use.

[CarBizIndio]

It would be nice to mount 3 of them inline

If you want to see more of the Rotec radial in a bike or even in a (gasp!) airplane (imagine that!) hit this link: http://www.rotecradialengines.com/
You'll get to see more of this marvel, too. I guess you could call it a "V-twin/V-twin/V-twin & a half"...

Nice,,,
You won't be stopping that from turning with your hand....well at least not more than three times.

Crap!!! :2purples: :2purples: :2purples: :2purples:
I am a pretty mechanical guy.
If it wouldn't run, I wouldn't have a single clue.

I think that continental would be killer in an OB configuration. Just remove the powerhead from something like an OMC 235 from the 80s. They were darn near bulletproof. Put a squirrel cage cooler on the top to draw air through it and run like stank.

[jmherbert]

Some years back (5-6 I think) I saw a custom made boat with a Packard Merlin V-12 engine that was meant for a P-51 Mustang. The guy said something in the area of 2000 HP at 2500RPM (?) A white and yellow 30 something foot boat on Havasu. The thing made blown bigblocks sound like weedeaters.
He said back in the old days (60's-70's) a lot of offshore boats used these motors cause they were cheap on the surplus market.

Thats what I'm talkin about. Now those are some motor specs. And I'd love to see the internals on that
