- In todays video Jay takes apart a 400HP+ CanAm Maverick X3 Turbo RR engine.
The CanAm X3 Turbo RR engine is an awesome engine. These engines use a CVT transmission, come turbo from factory and is a lot of fun. The one here has seen 10,000rpm, and pushed 40psi of boost. Before the teardown there was signs of the cylinder head may have lifted. This is where Jay steps in and takes a look at whats inside. Check out the full video to learn more.

First-time viewer here. I just have to say how nice (and rare these days) it is to see someone who REALLY knows their stuff.
Thanks for watching! We have tons of videos to check out 👍
Check out the rest of their videos if you want more teardown porn lol
I suffer from anxiety really severely at times. I can literally turn on this guy explaining stuff and it chills me out. Thanks for the vids bro.
Thanks, take it easy and learn to enjoy the ride.
I run the 1630 ACE motor in my race skis, full forged and balanced rotating assembly, billet cam, fully ported head with all the valve goodies and supporting mods, hammering it the entire 30 min race on the limiter at 9500rpm and the darn thing holds, they really are impressive motors for their size. You are spot on with head gasket issue, on our end the only other issues I have ever had was crank walk from the motor flexing on the crappy motor mounts and miss aligning the impeller shaft, but really cool to hear your expertise on this type of motor, I always hoped you would tear into one.
Not bad, not bad. Happy with results considering the situation. This was built loose due to predicting the lack of maintenance it would have and we had about 4 business days to get it going for the next race. Definitely pushing too much boost for months of torture.
Wow pushing close to 500hp/ liter is pretty crazy and these machines are hammered WOT constantly.
Well, this is a little more powerful then my 250hp 1.5 3 cylinder in my fiesta
I’m probably the biggest 3 cylinder fan ever. My favorite engine design besides the V12.
Have you heard one in person at high boost? The sound is really something! Thanks
Super cool video. Very informative. I really like how you addressed the scale of this power unit
I gasped when you said 40psi of boost in that small 3 banger
Appreciate your time!
Thanks for the awesome build breakdown Jay!
Love love love!!! This teardown. We work on x3 chassis on a regular basis, it's good to see an in depth teardown and what to look for.
Glad you enjoyed it!
The way jay says lubricity when talking about those little pistons just gets me all fired up. Great tear down and focus on attention to copper ring crush.
Thanks, Dustin!
Im workin for brp, and this engine is a beast! For 900cc can take so much power before something happenin, factory 200hp and its tame down at 200hp ! Amazing video!
Right on!
- Jay
Hope I enjoyed the video? I loved it! Thank you sir, this was awesome .
Such an awesome breakdown ur da best jay!!
"A lot of small parts doing a lot of work" statement earned your channel a new subscriber. I have always been fascinated with small engine
/big performance subjects.
Thanks for the sub! and welcome.
Great analysis of this motor. Thanks for sharing some great insight when disassembling a motor.
Thank you Sir, great vid ! love those 3 cylinder configuration engines ...................especially the sound of that Maverick ...................
First time viewer here as well...... Really enjoyed seeing the Rotax engine being torn down in this setting. Thanks for the content!
I enjoyed the vid. At this level I would throw the book at this engine with the appropriate coatings and treatments on every moving part.
Definitely enjoyed the video!
Nice work, Jay. Thanks.
insane little power plant!
Love my x3, close to 230 horse stock turbo on e85. It runs!
Another awesome video and a great learning experience. Thank you
Thank you, Like 2vintage channel, always a learning moment
Love seeing this little motor 😍 ❤️
The fact that you don't use impact tools to break things loose says a lot about your work. Great to watch and learn from, Thanks
It's cool to see something totally different
Subbed. Like other have said, not only someone who knows their *ish… but communicates it in an appropriate level of volume, speed, and cadence… I am looking at a used one of these and knew nothing about the engine (which makes me pucker up pretty good). After weeding through more “cool kid” videos than my patience can handle, I found this. In about 10 minutes I roughly understand it. THANK YOU!
That's really cool to see 😎
Thank you
Great job!
i liked this. And I like it was off the cuff and not read like a robot
I would love to see the Polaris 2 cylinder 925cc turbo disassembled and compared to the Can Am, see how they did things differently, and things alike.
In regard to the cylinder where the ring end gaps were aligned: At some point as the rings rotate around the piston, they will come into alignment and perhaps the alignment coincided with the instant the engine was stopped.
A while ago the workshop of the dealership I worked at purchased a reconditioned short block Mazda 3.0 V6 for an early MPV (RWD) and found it had oil consumption and oil burning issues when recommissioned. After some weeks of attempted diagnosis, the Head Mechanic stripped the engine down and found the ALL of the ring end gaps were aligned. This was no coincidence and led the mechanics to believe the workshop that reconditioned the engine failed to space the ring end gaps. I alweays thought that spacing the ring end gaps was overkill until this point.
Great video. I'm subscribing.
In that case isn't the question WHY the rings weren't rotating around the piston as they normally should?
This shit rocks right here... thanks for not just being another thoughtless gear head and bringing some actual knowledge to thr web..
I build exp aircraft as a hobby. Very good video
Work great in experimental aircraft, small, light and powerful
Great video!
On the Classic Minis they make a flywheel with a sintered center that helped get rid of that welding on the taper. Alternately there was an aluminum flywheel with a plasma sprayed friction surface.
I would love to put that top on my A-series. 😛
I enjoyed this motor content.
That is serious power for such a small engine
11:51 😂 that crack shaft dance
I do love open deck designs, if nothing else they inspire people to learn how to wrench on their own shit
Everyone keeps talking about sustainability, and here we have a small footprint, light weight, high hp engine which uses half the material and is probably pretty good on fuel. These would be awesome in regular vehicles! Very cool.
Hell yea we enjoyed it! Nice breakdown buddy!
“The Engine sounds MEAN when it’s ON THE PIPE”
Wooo!
Ski doo uses the same engine , their crank taper for the pto end has a D notch, mine was a mild pump gas tune to 205 hp in a 460 lbs chassis was insane on the trails
That was a great little tear down vid! As a fellow mechanic, I enjoyed seeing something new to me. They sure work those little things hard. Personally, I hate CVT style transmissions and they way it makes engines sit at full noise
I am not a fan of CVT either but in this case the belt keeps the engine from having to accelerate from lower engine speeds and I really think that shelters it from the effects of longer cycle times under stress. Lots of stress at low engine speed generally brakes lightweight components. Thanks
@@jaymeagher1510 Yeah, I understand what you mean Jay. There IS some middle ground, I know load at low RPM is hard on engines. Just like boost at low RPM or nitrous at low RPM is hard on motors as well... I wonder if these race cars would have been quicker with a nice little 6 speed close ratio box, with a clutch pedal and the ability to engine brake in a very controlled manner
@@danielbrealey2924 I think we can have that answer in the YXZ, it's just a lot of work to get it there. Thanks
Awww nice keyring
Would love to see an artic cat z1 turbo 1100, awesome to see. Thanks
Just needs a gearbox and a small aerobatic airplane 😍
Always wondered how they hold up I run a good bit more boost on my x3 and change the plastic gears every 500-1000 miles. They tend to break running the motor cold
Man, that would make a great motorcycle engine!
It’s in the can am ryker, 3 wheel motorcycle
Can you guys make some adapter for it? I really wanna put one in a kei truck...
I need this in my Geo metro.
Talking about the plastic gears, I have a 2019 Commander 1000 (rotax 976 v twin) and the water pump drive gear broke and cooked the motor.
🤣 that engine is smaller than my gaming pc case
What's your take on different magneto engines that are tapered keyed and start to develope galling in crank nose, balance? Electrolysis? Detonation?
Must be cool to have that engine on a old mini cooper 😅 or a gr corolla engine 🤔🥵
Please make a video building this engine
If the O-ring was not compressed in what looks like the same spot (13:07), is that a weak spot in the deck of the cylinder head, asking cuz it looks like it's in the same quadrant of the cylinder?
I would have liked to know what the bore tapper is? Especially if been honed.
Nice to see someone using non-powered tools. No rattle gun to be seen!
I'm sure my hands would hurt less with power tools but I avoid using them for the most part. When I was a flat rate tech I was pretty guilty of wielding impact guns! Thanks
I'm planning of buying a 2020 X3 xrc with the ace 900 triple. My concern before hand is the life expectancy of the engine
in your experience if I were to take really good care of the maintenance and not drive normal I plan on doing 75% of driving on road a little trials is 50k miles realistic with not going near the engine or rebuilds?
I wonder if you could make a lightweight brass idler gear for those or titanium, maybe even carbon fiber. Just a thought 🤔
now we are talking!
Have a 2021 Can-Am Xmr turbo RR had sunk it snorkel kit wasn’t hooked up properly brand new motor less 80 hours sucked up water brought it back to the shop change the oil in it about six times wheel and coolant continuing to mix change the head gasket didit fix the issue so pull the motor start taking stuff apart pull the stater case off and it was full of coolant inside stator cover any suggestions what could be issue I can’t find anything online about any issues like this .
Stock or modified?
,parts look upgraded and block looks modified as well with closed deck?
How do these come as standard?
Please more information on these engine please.
Nice Tech Work TY
How can you find the tdc on the maverick x3? Which cylinder should be on top?
Now _this here_ @1:35 is what you call *galling* . Two metal surfaces in direct unlubricated sliding contact, where the pressure breaks the thin surface oxide layer and the materials cold weld together. One of the materials will simply rip out some of the opposing material, causing a run-away damage effect.
It's gross isn't it? Thanks
@@jaymeagher1510 If you have the opportunity to fabricate (or have fabricated) the opposing receiving conical part: Back in the sixties, ARMCO developed a stainless steel with greatly improved galling resistance. It might help in alleviate/reduce this problem from happening if you can have it made in this steel grade.
You'd have to look for NITRONIC 60 (UNS S21800) stainless steel bar.
@@Hydrazine1000 Thanks, I'll look into that. I was thinking we'd pin it for now, it's an easy procedure and will keep things stable until the next thing breaks.
That would be a nice engine for a 3wheeler.
Hmmm , that motor in a go kart would be a hoot , until it all goes bad.
Have you checked for oil in he starter ? Might mess up the brushes.
Excellent video, thanks! To what application was this engine put to? Motorcycle? Automobile? Drag racing? Endurance racing? Street driving? Knowing how the engine is used would help me understand better the shape that it is in. Thanks!
A Drag Racing side-by-side
The name on the side says it all. Rotax.
I think the rotax 1200cc from a skidoo is a better block for this amount of power and it has a balancer shaft for vibration
For sure I have the 1630 in my race ski and it holds strong!
no its not by a long shot..
Polaris Prostar 2.0 2000cc motor next please
it all allows so much slip so that these things dont break rods im guessing, its crazy how these things and bikes make so much power but yet would be no good for moderate to heavy vehicles.
Reminds me of a complicated version of my Honda GX200 that makes 2.3 hp per ci NA.
not even close lol..
@Gregory Crowder 27 lb engine that makes 40hp. Very impressive considering its a 2 valve with no turbo.
The nose of the crank probably ended up the way it did because it was never designed to make the power it is
There are guys making more power than that. There must be a solution, but the presenter is used to tearing down other engines and didn't really know the answer so he just left it at "That needs to be addressed." I'd be saying the same thing, lol.
@@mjodr Just because other people make more power on the same platform doesn't mean it wasn't designed for the power they're making. It all depends on how you utilize the power. If you're hard launching it every chance you get, it can give these kinds of results. If you're relatively easy on it, it'll last a bit longer
@@richardwilliams9181 I think you missed the point of what I wrote. There are side by side guys making more than 400 horsepower on this platform. I'm pretty sure at least one of them has found a way to not get that material transfer to occur on that crankshaft taper. Your original post was kinda suggesting "Don't do this, because it doesn't work (with 400 hp)". My point is people are making MORE horsepower than that in some crazy builds, so what are they doing to combat this?
It's clear from the video this is a drag racing motor. Their goal is not to launch it softer to make that part last longer.
@@mjodr What I'm saying is the problem is a problem because the engine platform was never designed to make the power they are making. It has the taper fit because it was only designed for the factory hp rating whatever that is. I wasn't trying to say "don't do it". I was only stating my opinion as to why it happened. Different applications have different stress put on specific parts. The material transfer is caused from too much load on the clutch or whatever coupling they have and the engine is powering past it. Much like a slipping clutch, but at whichever point is the weakest. In this case it was the taper. The clutch held and the engine was still making power. The power has to go somewhere when you limit it to such a degree (heavier clutch pressure/stickier tires etc.)
@@richardwilliams9181 So what is your solution?
You still sound like you are saying "Don't build these things, they weren't made for it." You think that's going to stop the drag racers who pour $100k+ into these things?
Is there a reason for not having a keyway on the crank?
What is the reason for a tapered crank snout?
Could you show it a teardown of a Polaris RZR 900 if possible thank you
help. i bought a x3 rr with a bad motor it may need to be board to 74.5 can i boar these cylinders...
Yeeeee
Is that a realstreetperformance?
@realstreetperformance How is the engine so clean as its being taken apart? It almost looks like it was hot tanked but its fully assembled. How many hours did this engine run before it was torn down in the video?
Engine builder in the comments said they ran it for months. Must have been cleaned somehow before teardown.
The engine has been cleaned before on previous builds. Where it is located and how it is raced it does not see a lot of dirt.
This seems like a good motor for a cycle car. Imagine a Healy or Midget with one of these
3 cylinder motors are amazing. This would be a blast in a little roadster car.
Would be awesome in a smaller airplane
They think 180 is crazy power this would make 250 easy and live
I thought it could work for a car like the Austin 7, Fiat Topolino, Hillman Imp, MGA, MG Midget, Frogeye Sprite, Morris 8, Ford Pop, or something similar. Question is what transmission do you use and how do you fit it?
I've had engine engineers in training class you can put rings in any position and they will not be same position as installed. Many go thats not true and claim all their engines are in the same place as installed. Engineer had video and pictures from small 4cyl, V6, V8 to big truck engines proving this. Guy goes cat had a problem with engines using oil. Taking them apart all ring gaps where lined up. Which is BS I took many of these engines apart for using oil. Problem really was liner honing and rings not seating in. Other problem drivers turning engine fan on if they see temp of 200 deg coolant temp or when they go up a mountain. Running engine at min temp of 180 engine will never break in.........All street guys stuffing in 160 deg t-stat from old to current model. Real reason was coolant ran through intake manifold trying to keep intake air temp lower. Funny most engines now are dry intake no coolant LOL.
Correct ne if I'm mistaken, but 400hp without doing head studs? Isn't that just asking for trouble?
how mutch does the whole engine/turbo system weigh? the high performance experimental stol airplane space have been using a very rare and old snowmobile engine. this might be a competitive and available alternitive.
According to Rotax approximately 126kg or 277lbs. www.rotax.com/en/products/rotax-powertrains/details/rotax-900-ace-turbo.html
These would make great airplane engines! Like 250 hp would be crazy power for the weight
Good luck with certification...
Rotax makes aircraft engines already. The rotax 912 is used by trent palmer.
@@dustinnisley5924 does rotax make the can am motors?
I bet you can put these mills in a small car, like a Ford Pop, Austin 7, Fiat Topolino, Fiat 500 or similar. Assuming you can find a suitable transmission. Has anyone ever done this? If so, what transmission did they use?
Is that motor built for drag racing? I see the Can-Am racing in the Dakar and other rally racing, and they are very good motors, powerful and reliable. Only issue is the belt on the CVT, can’t let it get to hot or it breaks.
Keeping the belt cool is a technique that can be learned. I have never burned up a belt.
This one is for drag race use.
@Real Street Performance - What really caught my attention was the indifference given to 'piston ring orientation'. Thus, was a compression test done on this motor to see the difference in individual cylinder contribution? So ring orientation isn't critical in performance engines (the closer the ring gaps lining-up, doesn't affect power loss)? How does one prevent ring movement to the point of their orientation robbing power? Can any such ring movement be prevented, or minimized, by orienting them more than the 45° (or whatever's called for) during engine assembly?
simply, you don't. you can move the rings to whatever orientation you like initially for break in but as the engine breaks in and runs those rings will "spin" around the piston as some points they'll line up but as it runs longer they will again keep spinning around and not line up... i think the crosshatch on the cylinder walls helps them spin...
but realistically, you wouldn't want a ring to stay stationary you'd want it to spin and evenly wear all the way around as the engine ages..plus a spinning ring means a ring that's able to do its job.... if locked in one place it'll just get coked up from carbon and quickly cause compression loss..
only engines i have seen that stop the rings from spinning are little 2 stroke weed eater type engines I have seen have a pin that stops the rings from moving.
but those engines also dont live or work and run for as long as these engines do.
@@gregthemechanicman Pretty much every gasoline 2 strokes engines have an anti rotation pin so that the ring gap stays in one place on a supported part of the cylinder. They don't live long if the pin comes out as the ring will rotate and catch in a port
@@joelg6740 ya but that’s 2 strokes, on 4 strokes, they do spin. I always set them up the way the manual says but they always don’t end up in the same position when rebuilding.
Can-am has a pin in the ringland on seadoo 2stroke engines to keep the rings oriented..
@@grunfieldf8694 Thanks.
Must be a race engine as the weaknesses (shortcomings) are exposed. At 40 psi boost that's a lot of punishment.
