Worlds largest 2 stroke engine
Passing Lappers
KTM makes a 540 as well as a 550 two stroke single. But who wants a
K-mart Trail Master road racer.

Maico made a 750cc single that Super Hunky of Dirt Bike fame rode in the
Blackwater in the early '80s. The motor was made for the ISDE so Maico
could beat the BMWs.

Saab made some 1500cc two stroke three cylinder cars. You'd be
surprised how small the motor really is. I know a guy who has a couple
of 'em.

For my project it has to be a single cylinder, water cooled 2 stroke. I
am currently running an RZ350 twin(same as the banshee)
There are a couple of guys running H2's, but I tried running an air
cooled 2 stroke, and it just aint cheap buying pistons by the case...

KTM makes a 550cc 2 stroke single. It's supposed to be the more
powerful than it's japanese 500cc opponents. It would probably be
better for roadracing too, since it has a smooth strong pull instead
of the tire-smoking midrange hits that the 500's have.

Maico made a 725 or 780cc (something like that?) for desert racing back in
the early '80's. But, just forget about parts...................

Big two strokes? Try pile drivers:
Stationary piston, moving cylinder, no crankshaft... gravity return.
four foot stroke, three foot bore.
Piston port about the size of a football.
Another big two stroke .... try the 600hp V6 Detroit Diesel that powers
the Bradley Fighting Vehicle of the US Army. Twin superchargers, twin
turbochargers... something like 1200 ft-lbs at 1500 RPM. Serious
noise problem.

Years ago, Maico built a 760cc (or thereabouts) 2-stroke single. The
idea, as I recall, was to run it in the open class in the ISDT. It had
to be bigger than 750 to be in that class with the rules in effect at
that time.
I don't think that it made any more power than the 501, though.

There are two-stroke diesel engines in big ships that have cylinders
that are several stories tall - might be a bit cumbersome for a race
bike though.

Brian dude, where do you race? I've seen some pretty insane dirt-track
racing at Blackland, awesome stuff. Great to watch. I wonder if someone
could make you a "BIG BORE" kit for the KTM 550? I've nver heard of such
a thing, but stranger things than that are routinely done to bikes.....

Or you could go with the Detroit Diesel v-8 that is in the HEMTT 8x8
vehicle.... also in the 1070 HET.... It puts out about 500 HP
Operating range is 600- 2300 RPM.... The torque is about 800FT-LBS
or so....

A KTM 550 motor would likely be the best bet. Stock pipe and porting is
around 70 HP (pulls *hard* from an idle), with an FMF Fatty pipe is
around 75-80 HP (softens the bottom a little and wakes up the low mid
and up). I'm using a 440 FMF Fatty pipe which lets it rev a little
more.
You'll may need larger radiators and/or modified water pump for
sustained high RPM. Its a 9 plate clutch, and should be able to hold
the power ok. Piston is Mahle and the cylinder is Nikasel coated -
engine durabilty should be ok. It is reed inducted, non powervalve, and
more fun than humans should be allowed to have. It starts very easily,
3 kicks cold, one warm, but requires a serious boot.
Can you post pictures of the first time you gas it with a slick on it?

Well it was a 500, but it seemed to have less low end than a 125 that

Hey try this "Harland andWolf" two stroke diesel ship engine 900mmbore
1800mm stroke 21,000 H.P. approx. 4000 hp. per cyl.
Edwin R Nickerson
Abit off topic but interesting...
Currently the worlds largest 2-stroke happens to be a Wartsila 2 stoke slow
speed 12 cylinder diesel (inline) generating, get this, 66,120 BHP (bhp is
the actual usable HP, total HP is over 67,000) ands runs at 94 rpm full
throttle. It can achieve 100 rpm for short periods of time if required.
Not much on the top end but good torgue all trough the power band!!

It is a two stroke diesel. It has injectors, piston port and a single
valve.
Another piece of trivia, once the engine is started, it is never allowed
to
stop rotating. All maintainence is completed with the engine rotating
at about 0.25RPM, driven by a donkey motor( your basic 1000HP medium
speed diesel). There are ladders inside the crank case, up the con rod
and on the inside of the piston.

Not an exact answer to your question but the large marine diesel 2 strokes
tend to get about .3 pounds of fuel per horsepower per hour, compared
to .4-.6 for a good automotive 4 stroke and .6 to .8 for a carburetted,
motorcycle 2 stroke. So, while it's sucking lots o' fuel it's very
efficient- probably the most fuel efficient internal combustion engines in
general use are of this type. Plus they burn unrefined crude oil instead
of expensive Trick gas ;).

Is it called bunker oil? If it is, it's more like tar than fuel. They
heat it way up just to get it to flow. Or is that what they use in
oil fired marine boilers? I remember seeing a picture of a low
pressure steam steam piston in a ship that was 10 feet in diameter.
Just rambling.

A good rule of thumb with Marine Diesels is that they consume approx.
1 gal./Hp/24 hour period running at 80% load, which is the typical
koading
for a marine unit at full cruise speed.
So, 20,000 HP unit will burn approx. that many gallons a day.....

Must really big diesels are two stroke with super and turbochargers.
Most really big diesels power boats or should I say, most really
big (non nuclear) boats use big diesels...

Wonder what kind of OIL they use in the crankcase?

yes they do have cams but they are firing every 2 cycles. They have
intake ports in the cyl liners and air is forced in with a supercharger.
