Hi Matt, great teardown and explanation. I was expecting to see traction rollers to be honest, but on a bike I guess you cant hear the gear noise anyway. Something that may be right up your street is my own channel, where I teardown and explain Formula One parts in a similar manner. Please be sure and delete this comment once you see it as I dont want it to come across as spam or self promotion, just making you aware is all. Regards, Brian, Ireland.
Send me the link dude, and promote yourself, there's room for everyone.
I know this bloke called Del,he’s a welder.All the best.
Solid tinker... in more than one aspect, welder is a tad 2 much.
Thanks Steve! 👍🏽
(and Matt, of course... !)
Nice one Matt. The supercharger has been living in that box for a few years now. I had to evict the spiders before posting up to you!
How did it get damaged, did you drop it?
Thanks for letting us have a look see.
It was from a crash damaged H2. I purchased it a few years back, as I had never seen any for sale. Sadly, I did not get to the the state of the bike it was from!
Very interesting matt
may I know how much you pay for it?

Awesome video, and so interesting, learned so much. Well done Matt!
Matt at his best. Excellent Exploration of the supercharger.
Superb Kawasaki engineering.
Love this type of content. More of this please
I stripped a Karcher pressure washer... that had a planetary gear set in it..... Got to love 5 axis CNC machining..
I'd love to hear it with a straight cut gear. If it's anything like a sequential gearbox but on steroids I bet it sounds nuts.
beware what you wish for, the sound of spur gears (in this application at least) is a love or hate affair, and most tend to hate it. in your mind moto guys likely visualize RC30, RC45, RC51/SP1 but unfortunately this is not that (in fact it's quite the opposite). the sound fitted to a V8 or V6 Mustang will likely make your dog try and jump through a plate glass window.
Great expose video to show all that there is no myth about a superchargers make up. Any Kawasaki dealer will swear down they have expert technicians which they don't. The blanking plate you mentioned is a type of set screw which around it is a fine metal gauze filter to clean the oil prior to entering the main shaft. The filter replacement is part of the 32,000 mile service which Kawasaki charge £65 for. The service advises you to replace the blank plate which comes with factory applied lock tight and the small filter the size of a thimble. The lock tight has to endure temperature up to 200c. I bought the filter and my own lock tight, job done.
I was hoping you were going to clamp it in a vice and attach your drill al a Del style but fair play. Not sure I'd have the balls either. Thanks for taking the time to explain how it works.
Not to mention no lubrication lol.
this is a miniature version of the GINORMOUS Pro Charger F4X-144 Crank Drive setup fitted to the front of 2022 NHRA Pro Mod Champ Ryan Martin's 2019 Camaro. It's a great compromise of giving better aerodynamics/sight lines over a traditional screw blower (although some could argue the sound and visual of a massive scoop and throttle body sticking up through the hood is a thing of beauty and I won't disagree with these people 😊) and the high RPM boost pressure of a twin turbo setup without as much of the heating of the intake charge. cause for all it's insane levels of boost pressure, the turbo's "achilles heel" is that while the heat of the exhaust not only drives the turbine, it also obviously heats the overall turbo housing, the compressor wheel, and intake charge (something the physics of compressing air already does regardless of method) this often then begets the need for the added weight and plumbing complexity of an intercooler which a Kawi H2 noticeablly does without (compare to a drag ZX14 or drag Busa).
Can you hook the shaft up to a drill and make a smoothie?
Turbos and supercharges introduce a whole new level of variables into the mix...
This in detail videos got me liking this channel
Fantastic, so interesting and Rare.
22:48 *lower right side* Even the spider was interested and wanted to be a part of it.
I could watch hours of this.
Thanks Steve
Curious to see the impeller shaft bearing and oiling setup.
Thank you for that Matt, most interesting. Love great machining.
I guess it moves so much atmosphere, that it is bound to collect a lot of fine particle debris. I used to imagine I was impressed by high quality parts, until you showed me this. Now I truly realise what I had been missing out on for a comparison.
Really enjoyed that matt thank u .
I've got the air starter for a Spey engine, and it's very similar. Obviously it's larger with a bit more oomph. Great video!
Brilliant video thank you ❤👀👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍
Thanks Steve, very Cool!
Really interesting. Thank you 👌
That was too-much!! Thank you to you both 🙂
Really interesting video cheer Matt
I don't think the welding repair would be too much of an issue, but the machining back to shape would take a bit more skill especially as you mentioned the bore was tapered.
The impellor is a thing of beauty.
Great video very well explained
Bloody hell Matt, I was just looking to do something stupid to my 125 and been thinking about supercharging and looking at cheepo turbos from ebay or Amazon to split apart and drive with a belt from the crank shaft but a planetary gear set up would be much neater.
I can't believe I've just watched a man for over 55 minutes talk about a supercharger but I did, cheers Matt. The only problem now is that I could go on for about an hour with questions, but I won't. I would like to know how the outlet the housing got damaged like that.
Now that was interesting
What a masterpiece 😍
Wow! What a piece of art. I noticed the plate was handed before you took it off :-) smug face lol
I used to machine impellers when we made jet engines for RC model aircraft
Thanks for that Matt. Very interesting and informative. It makes me wonder why they (Kawasaki) put so much development into this system rather than the main engine instead? I've never ridden a H2 so maybe if I'm lucky I will find out. 🙏
Hi
I've been inside a lot of turbo's of all sizes and I don't recall any of the volutes being dowelled to the bearing housing, after all for any given bearing housing there will be a selection of volutes, compressor and exhaust turbine wheels. Remember Kawasaki is a massive company that shares technology with Hitachi and that bearing housing might just have a job on something else
Keep up the good work
It would be great to hear the bollox dellsplaing this compressor
Just to let you know,I have Wera Hex/Allen + keys, the best, did you know they do the Hex+ in bits? So you can put in a drill, screwdriver, socket set.
I also have the small ratchets set for sockets, bits drivers too, awesome bit of kit.
That’s a big ass turbo for that bike! What’s that bike displ.? 998 cc or something liked that? Looks smaller when you see it in the bike.
Rotrex do similar stuff for aftermarket. Iirc, they are belt driven.
You can clamp a piece of rubber hose around the shaft, then clamp the other end of the hose around an adapter or something, and spin it with a drill that way.
So you can watch something that spins spin...
cool 😎
23:17 even a little bug in the bottom righr had a look at the the turbo.
I guess they went for centrifugal supercharger because it produces the least amount of heat and it's easy to package. I don't think the H2 even has intercooler? Very nice "simple" design.
do you think that metallic noise coming from the intake that every h2 h2sx zh2 has could come from the impeller bearing ?
Regards the spin speed of the turbine, is the drive shaft to those gears direct drive from the crank? Just wondering if there's another slight step up in speed to the turbine unit through some other engine gears?
Its a single step up gear. 5:51
That takes the 14k of the engine via chain to 16k at the back of the charger, at the planetary gear set.
Meaning the supercharger at full engine speed is doing about 130000 rpm.
Nice air pump.
Good Blower
I remember the Honda CBX. Two extra cylinders to produce enough power to carry the weight of two extra cylinders. How much does that thing weigh?
I bet 2kg max. It is mostly aluminum hollow housing and heavy parts are gears and shafts only, which are tiny and lightened.
What drives the turbo is it the crankshaft on the H2?
Great bit of precision engineering.
On a side note,I bet your
Mrs wish you get that excited ,,drooling ,mesmerised and loved up about her than the H2R impeller supercharger when she sees this video!🤣🤪
No offence.
21:20 u cant bugger this up
let Del have a go at it , 12 minutes and som anglegrinder later : well and truely dickered 😁
I’ve photographs of my supercharger stripped down completely, after bearing failure, Kawasaki will NOT supply new bearings, in the end we found bearings but some machine was needed , long story as this hasn’t been done before as far as I know , ceramic bearings needed as it spins at 130000 rpm 3.500£ for new one ☝️
I'm curious, you mean it uses ball bearings? I thought all turbo use liquid bearings.
Any chance you have a contact info? I subscribed already,if that's worth anything. But would like to see and if you documented it as a page to follow. Mine has weeped oil since new,i would like to fix that. Would like to see the direct failed part. If any.
@@inevespace lots of turbos have ball bearings. Big topic in the car scene as there's always arguments about spool time, wear, frictional losses etc. Both types have seen success in big builds though so you'd probably have to do some digging through all the corporate sheen to find any solid answer
@@gregburls3699 they are designed to pass a little oil , that’s what the little clear bottle is for , simply pour back in . Also oil level!! Only fill to slightly above bottom line on glass telltale….. if any more , the oil ends up in the air box 📦 remember that the oil expansion is a lot when hot 🥵 so will show up around the top level mark
@@mobleyuk how did you know the bearing has failed ?
There he is. And something even i found interesting. 9to 1 from kaw,btw.
I digress,I heard that even second hand,but a trustworthy source. Anyroad,8 to 1,9 to 1, it's all holy sh** fast!
wow nice planetary
perhaps the reason for the missing dowel is so the casing can be rotated after the fact to help with fitting?
Could be, but the housing doesn't accommodate the dowel at all.
@@dirtygarageguy that's kinda what I'm saying it's possible the turbine and gear assembly is manufactured separate from the housing which can have a few different types some of which have a dowel the one you have just doesn't
I don't think so, kawasaki could be full of shite, but they said this was developed for the H2 exclusively. I don't know why they'd lie.
@@dirtygarageguy I got impression that the plate where oring sit works as a huge dowel.
What would a complete unit as u have there cost matt roughly.
Just under 5k
What happened to the lighting?
This would do for lightly supercharge small car engine, could be driven from AC compressor housing with clutch and can have air running through while clutch is disengaged for low load driving, so none of that 3 throttle bodies bullshit :v
I wonder if that gearbox is a part from something else from Kawasaki heavy industry
They probably lifted it from angle grinder 😂
I wander what it's power consumption is compared to an equivalent capacity roots or shurock blower
Well, that's dependant on the bearings used and the air moved. The power consumption is based on the air pumped. If it ain't pumping air it's not doing work (minus loses through bearings)
@@dirtygarageguy yes agreed but the Kawasaki device is a turbine and the others are positive displacement devices and will have totally different power consumption curves for a given delivered pressure
The work done on the air is the same. So you work out the delta in pressure change, and volume. Any difference other than that is losses which you can measure on run down.
It's also not a turbine just to be an arsehole lol
@@dirtygarageguy don't know why I didn't see it like that bloody obvious really
10:00
Fuck me dude nearly gave me a heart attack
Put it on the SV / project Isaac
Is this the one of live stream guest's? XD
Yeah, can't wait to see him disassemble the other ones haha
a big compressor wheel machined and balanced in I'm guessing similar way, czcams.com/video/yTBGnEPNyg8/video.html
Pode ligar o echo a uma furadeira também
🤓👍 Venho agradecer a você é a todos que estão na família R1000

É agradeço a deus 🙏🤓 é aos inscritos tamos juntos
Really, I can’t just buy one of these and strap it to my engine. I guess that how all those Kwaka engineer’s earn their money.
Kawasaki isn't going to fix your problems. Just like the 2004 zx10r frame crack all of them do it.
These bikes are put together by factory workers. They are designed with that in mind. They’re not one off builds. Your sounding like a Mattbollocks.
What are you talking about? Reference would be good.
Excellent video Matt, the machining, design etc even to a non engineer is impressive. An example of human expertise and error, wonderful item that may have been wreaked through error of not showing thread lock on a diagram?! I'm sure there will be someone with an "ology" that could put a name to it. An excellent video thanks Matt.
Sorry buddy,these are high end sport bikes. Not you're one off definition,but they're not sitting on shelves. Made when ordered. Bugatti does that too,I think,js.
You’ve watched too many dellbollocks vids. Your now sounding like him but without the vids of actually doing anything. All the promised vids…Matt..”actually I’ll make a vid on that..”. Years later………………………….and I’m a fan of the channel. That’s how I know you’ll take it with a pinch of salt…..how’s your heart?
Hfor bbye
