Well, this isn't a dirt bike, but it is the most powerful 2-stoke engine in the world. It's a Cooper Z-330, 20 cylinders, 10,500 HP.:dizzy:

This is a natural gas compressor, used to pump gas down the pipeline. This is one of 4 in the world. This particular engine is in Great Bend, KS. There is another in Indiana, and 2 in Russia. The speed of these engines is quite low, about 300 RPM, but you can't imagine the torque!

There is a tool cart in the foreground of the photo, a control panel on the left. The 5 compressor cylinders are in the middle of the photo, the power cylinders are behind the railing, and the exhaust manifold is on the top.

You need to look up the Maico Six Days bikes of the early 80's. 760cc 2 stroke single cylinder! Might not be highest horsepower, but bet it was the highest torque. Maico's still occasionally pop up in the current dirt bike mag's for having some of the flattest, most usable torque curves ever. My '82 490 has amazing torque without being peaky...

Here's the 760 http://www.superhunky.com/nov00rsMaico760.html
A friend that had a Maico shop and was a factory rider back then still has one in his showroom - not many were made!

Yeah I remember reading about the 760 beast. It was an awesome feat to make such a big motor, and one that actually held together.

You wouldn't happen to know the name of the facility in Kansas that this engine is located. Great Bend is where I grew up.I think I know where it is but there are a few pipeline pumping stations in central Kansas and they actually closer to even smaller towns like Bushton and Claflin. It's been 25 years since I've been inside of some of these plants. I'm guessing that this engine has been added snice I was there. Even the older engines where pretty impressive.
PM me any info you might have please.

what gas company owns that Steve? i used to work with Northern Natural Gas as we had pump stations along our entire pipeline from Texas up to the upper peninsula in Michigan.

Sorry, since I wasn't given permission to publish the photo, I can't say who owns it.

Wartsila built the most powerful Diesel, which is more powerful than this, but I don't think it was a 2-stroke. I may be wrong.

The Maico was the king! You haven't ridden a 2-stroke until you rode one. You'll just have to get used to the shift arm being on the wrong side.

Pretty sure the KX500 made (makes) more horsepower that the cr500 or wr500. but turbo is right I use to have a maico 490 and that thing was insane.

This is a bike that I owned for a while, until I almost died one night racing someone over a bridge.

In the picture my sister is sitting on the bike and my father snapped some pictures. Or I looked more gay when I was younger then I remember.

I was coming home from my bosses house. And a guy and his girl friend on a big Honda four stroke which was about the biggest thing around in those days. Took off fast, so I figured what the heck.

The only problem was I had a World War One German National Gaurd Helmet on. It is the one with the big brass spike. I also had the chin strap inside the helmet and just laid on my head for showing. Heck I had no licence no registration I figured I better keep a low profile.

I had a custom made fringe leather jacket and probably looked pretty bizarre looking back.

But anyhow I take off and when I come over and down the bridge I catch some air. The chin strap falls behind my head and the helmet goes over my face. I can just see a little bit of the road from a little unblocked area. And what do I see, A double yellow line pass under the bike.

So I start to thinking there is oncoming traffic what if they already swerved and now I swerve back and we head on. But I said screw it I am going to just lean it back into my lane and stop the thing. Because I cannot get the helmet back on my head. It is now stuck over my face.

So I get back in my lane and rip that stupid helmet off my head and promise God I will not rid that thing again. What a night.




Sincerely,



William McCormick

That bike would just burn out. I forgot what the RPM's were but they were up there. It was a five speed I believe. I think it was reverse to other bikes as well. It was first gear up and 2-5 down I believe. It was different.

It was like riding a giant chain saw. And the fellow I had bought it from had it bored out from a 500 to something bigger. I really don't know how much over, but he said it was way over as big as you can go.

Sincerely,



William McCormick

I still have my 82 Maico 490 it was one of the best dirt bikes that I ever rode. It had a flat torque range that would let you tackle a hill and then tractor up it at a comfortable speed. It would still pull the front wheel in at least 4 gears raising the hair on the back of your neck. I havent ridden the bike for 10 years due to neck surgery and the fact that it seemed every time I pushed the bike to really enjoy it I managed to damage myself. I know that was a rider problem not a bike problem. The only complaint I had about the bike was the vicious kickback, on backfire, which would cripple my left ankle (also damaged) and that was even with the compression release engaged. It got to the point that I would stand off the bike and kick it over with my right foot (not damaged). I still kick it over a couple times a year to make sure the carb slide and piston is not frozen. I suppose I should sell it but it is hard for even a 50 yr old man to get rid of his childhood toys. Heck, as you can see from the clutter in my shop I have trouble getting rid of anything. Thanks for bringing back some very good memories. Chuck

I grew up in Freeport New York. And a friend of mine works down at the power plant. They are switching over from the old ship diesel engine to the new high pressure gas turbine engines. But as they were taking them apart I went inside to check them out and got some pictures.

That old motor used to power our whole town. Pretty amazing. Yet it could only push a boat along at 30 knots. One jet engine is now going to backup the whole town. The other one will spin up and act as a backup.

I'm liking the CR500. Too bad two-stroke bikes are no longer allowed to be sold new in the US--it's an emissions thing... I'd like to see it up against an XR650 or comparible thumper.

I'm thinking the most powerful STREET bike (not a converted GP bike...) would be the Kawi? 750 "Water Buffalo" liquid-cooled triple. I think it was made in the late 70s. Not unlike a snowmobile or pwc engine. Air-cooled I'm thinking the RZ350 which was a twin but very light and nimble.

The Natural Gas compressor station my Dad works at up here has two of the 12 cyl versions of that. You can stand in the cylinders!!! V12 engine with 6 more compressor cylinders of the crankshaft. iirc, the engine cylinders were 20" (????) stroke and the compressors were 16"(??). this is with like an 18" bore!!

It is a shame to see the demise of the 2 stroke. Growing up racing them will teach you how to ride like nothing else. I hate 4strokes. Hate the sound, hate the weight, the hard starting, you name it. They still have to almost double the cc's to get the power of a 2 stroke. I read that Yamaha is still keeping the YZ125 alive for now at least. I miss the sound of those things. Ditto on the Maico 490. Sickest thing I have ever ridden. Yeah yeah, I know the 4's are easy to ride, torque everywhere, blah, blah......:rolleyes:

Is this two-cycle engine big enough to mention?

Sorry it's so dark, scan of a film photo. I took the picture around 10 years ago, somewhere around southern Illinois, as I recall. Don't know much else about it.

The banshee quads had a 400cc twin that was known to drop 70-80hp with solid reliability. Those quads were scary fast!!! But the fastest, most HP per liter 2 stroke motor of them all??? Honda's 2001 NSR 500. 210hp, 500ccv4. Nothing exceeds like excess. The NSR was generally regarded as perfection in a motor.

My heart will always go to the old two strokes. Nothing like a well balanced oil injected dual sport to do a day's riding on. It takes a different kind of person do deal with the shortcomings of the 70s bikes, but I wouldn't ride anything different. I'm looking for a Kawasaki 250 Green Horn or 350 Big horn, or Suzuki TS 250 or 400. And you'd be surprised how well a good rider can keep up on an old bike like that.

I don't want to argue the horsepower numbers, but my understanding is that a KTM 490 holds the world speed record for fastest dirtbike, or at least it did for a very long time. I think the record was something in the range of 180 mph, but I could be wrong again.

I think the most interesting engine I've ever seen is the Cooper Horizontal series. Here is a link to some very large engines, including the Cooper Horizontal. There is also a video here of a Snow Horizontal, which is very similar.
