Kawasaki should win an award for these super charged engines, Just incredible what they can put out and so reliable.
Someone needs to inform Chris Moore of the engine similarities and potential of the ZH2. Hes living under a rock on this one.
How so he has ah zh2
That clutch cover looks sooo freaking good! When I bought my ZH2 new in 2020… I had no idea, I’d be seeing one with over 300HP!!! And thanks for clearing up that rumor about internals. The reason that never sounded right to me was because it would in theory increase production cost.
I have a 2018 H2 sx se made 271 hp when we finished. Stage 3 gears , full Vandemon H2R style exhaust, turbo smart blow off valve, H2 spark plugs, Woolich tuning software. Bike is insane. When we started it was around 170 hp . I also have a 21 H2 Carbon edition that I will be building over winter. I’m super excited to see what else you do . I have your parts on my bike. Including the custom oil cap , and boost gauge mount. Awesome work.
Please post a little bit of that build on your channel
@@ProudMurican_PVT-GR137 I’m going to do a video of the build , some dyno runs and the finished product.
Blow off valve doesn’t give you any kind of performance. I feel like the stock valve sounds better than a bike that whispers to me when engine braking. I’ve been trying to make a bov that does the high pitch noise you hear on turbo civics but it’s hard to get that sound with a supercharger. Nice build tho, bikes at 200hp are nuts as is, but 270+? I bet she rips the concrete apart on the interstate. Badass bro!
@@TheBigChad I know it doesn’t give any performance, but it definitely changed the way the bike sounds. And it looks really good. The bike is the shop now getting a bunch of carbon fiber parts , and a roaring toyz swing arm .
@@chriswade3986 I’m not hating on it at all!! I love the build currently. That swing arm will be sexy af too
You made your own plug... Fuck you amaze me every time Benny! Well done.
Wow!! You’re the man!! Thank you for all your great videos!! You’re teaching the world about the ZH2’s!! 👍🙏😊🏍
good to see you back
thx for restoring the truth with the h2, everyone saying it has weaker piston than the h2.....now we know
and amazing result of course, would love to see the bike on road or track
I think this officially makes you an evil genius!
Great video Ben!
Spectacular! Excellently done process. Thank you.
Great video! Answered a ton of questions I’ve had with my ZH2. Knowing now they are very similar internally to an H2 makes me feel better. I just installed your intercooler and now I want to add a flash.
Thanx for the upload Ben
Hi,back again,very informative with your internal engine components comparison. I've owned 6 turbo busas,1turbo zx14.great work,much appreciated
Well done my friend this is so perfect .so much power .
My favorite bike. Zh2 is just a monster.
Great video!!
Bruh i cant imagine what its like riding on this beast, my 255hp h2 is already insane. This is just on a whole'nother level
Amazing clutch cover ❤
THAT is awesome!
Thanks for sharing and explaining.
Awesome mate
Thank you Ben for what was a very informative video explaining in detail the pathway to what are stunning Hp numbers from what is or was a difficult engine to get such good power numbers due to the higher compression of the ZH2. E85 and the timing relationship were interesting and answered a lot of questions.
I didn't really say it in the video but your exhaust definitely made a big difference to flow once we were able to get some timing into the motor. It is LOUD with the baffle out but I love it & the quality is awesome.
@@extcreat Great hear and regarding the muffler kicking out more due to the use of a single-sided swingarm over the original twin rail we can if you intend on sticking with that spec possibly bring the muffler in by using an H2 or SE/SX link pipe?
Can’t wait to see a update on this
Fuel tech Brazilian number 1
Ben is The Man! 😍
This the power i want for my ZH2🏆
Great work, and fantastic results. You mention fitting the swingarm from an H2SX won’t work as it hasn’t got the cutout like the regular H2 has. The cutout in the H2 swingarm is for the fuel pump bulge in the under tray, not for shock clearance, I’ve fitted H2 Ohlins to a SX with no clearance issues. The SX swingarm is 15mm longer and would give you some help during launches..😁
Yes you are correct about the cutout,. Realised what I said afterwards.
Man I need to come past your shop with my zh2 asap
Just WOW BLOODY WOW that is totally nuts thank you for clearing up the internals are the same as the H2 should shut a few people up 😂 👏👏💯👌
Very impressed, great job. Mine is quick enough as is though 🤣
Well done. Amazing numbers. What causes the initial dip when you snap the throttle open? Will that make it snatchy to ride coming off closed throttle?
Nothing to do with the bike, it's the dyno brake releasing , a different technique will show a different result in that area
Hi,awsome videos,very knowledgeable. Thinking of a 21 zh2,,ive researched this engine 11.2 compression. Are the higher levels of boost safe,per rods,pistons
Amazing results, mate.
You've got the best job in the world, getting to work on these awesome machines.
I've been contemplating for a while on putting a fueltech on my zx14.
Can I buy one through you?
We are not currently a dealer sorry, You can purchase through Dandy engines in Australia though.
Great work!! Quick question are you running a manual cam chain tensioner or supercharger tensioner?? Also will a h2 head bolt on to a zh2 head and work!? That is the question
Tensioners are stock, Kawasaki changed the design on these after the early H2, they now work fine, we've not seen any issues running them. Yes the H2 head can be used on a ZH2 but you would need to change the throttle bodies the velocity stacks in the plenum, the exhaust system.
do ZH2 and H2 share the same rear suspension? planning to swap single side arm like yours. Anyway good work on reach 300ps !
awesome video. so the cat removal wouldnt bring much in power? i have your intercooler in my h2sx, awesome work i got from you. But i have a little question: when riding 20km on autobahn at vmax i get ~70°C IAT on hot days at 30°C ambient temp (much lower then without IC, before i read 90+°C), so i have concerns about increasing ignitiontiming. On Dyno i have only 40-45°C. When i go to maximum ignition on this low IAT i guess i will kill the engine on autobahn?
You need to be careful adding too much ignition timing to these bikes especially when pump fuel, @ 70 deg C your ecu will start pulling timing anyway so there's no point adding more. I'm not going to quote an ignition timing figure you should be using as I don't know your exact fuel & engine setup, Im happy to discuss it further if you email me.
Awesome video, I need to ship you mine from the US. I have been posting about the internals and telling people about the internals being the same as the H2, my source comes directly from Kawasaki Engineering Department and Development of H2/Z H2. Great job.
Hello mister,
how much effort and currency did this masterpiece take overall?
Great vid btw subbed with a like!
Yoo thiss is insane i want one now for my first bike lol😂❤
the next step would be a big Super charger wheel + h2R Cams, pushing over +400 whp? there are few H2's in the world with SC upgrade and + 400 whp on the streets, it's always good to see how far the limit of this engine goes, new challenges, of course with the proper safety with forged internal parts of course.
There's an easter egg in the last 2 seconds of this video 🙂
@@extcreat I think I know the size of this wheel, it exists for the H2, upgrade, 72mm,76mm,78mm, there is the 84mm that has not been tested, just a "prototype", the 76mm is easily above 400 whp, the size of your new sc is 76 mm probably, hshshsshshs
@@extcreat I don't remember the size of the original H2 wheel, something around 68mm, the 72mm rotor already brings big power gains.
@@extcreat if you turbo this bike..... oh my lordy.
I just subscribed to your channel and im glad to know about the engine because I have the 2022 H2 SX SE and I'm wanting to make the same HP
You are a dyno grandmaster!
As the bike now has a stand alone ECU, could you please advise what maximum boost pressure the bike is making with the Stage 3 supercharger drive gears. My H2 SXSE+ blew up 2 x Turbosmart FCD2s . Both only lasted for 2 to 3,000 klms. Maximum boost was 21.6 psi
Ben I think I should ride it. Purely for more R&D
Cheers graeme
Ya. The curve was almost identical so the first run engine configuration was already hitting a wall/bottleneck. It was a system you hadn't modified limiting the performance. BTW, holy, man you are on it. Jolly good show. (sorry I was watching "The Bridge Over The River Kwai" today. Right, carry on.
🔥🔥
I am doing the H2 SX version of this build. What target AFR did you go with during the tuning process. I am currently using 12.0 at all throttle positions.
Apology accepted! Great job Ben! 🔥
Is the h2 swing arm necessary to reach out 316 hp? I was thinking to do just an extension to keep it on the ground.
Wednesday night a quarter at the creek. 👍
I have a Z1000 & Gsx S1000. Both are naked bikes. Both go about 155 mph in stock form. Can I achieve at least 190 mph top speed….by making modifications & ecu flashing? Maybe a turbo if necessary? Any suggestions?
Got 2022 zh2 and this is literally smh. Thinking to do all the upgrades you have it on here. Front wheel can you keep it down? Pls share footage when riding it pls
May i know what are the parts that they needed for Swingarm parts
Just to be clear, this was done on stock ZH2 injectors and only your fuel pump upgrade?
no we are using H2 injectors
Hi , just have Kawasaki ZH2 SE , i like to upgrade my bike but the drilling matter for a cooler i cant do it my self. Do u have the lower part of the cooler drilled? And what gears ratio to be fast top speed? Tnx
How much would it cost to get my hands on a zh2 with all this mods ? Approximately?
Curious if EC intends to design a Z H2 drop in cam or test dropping in H2/H2R cams.
Seems H2 cams with a 100 centerline on both will add a good bit over 10k, but should have gains from 4k to redline.
330+ seems easily attainable with a cam swap.
Looking at all the part numbers it requires only springs, seats, retainers and to be an H2 spec valvetrain.
Yes we have a different cam to use & yes you are correct about the valve components
@@extcreat love the development work. Nice to see a shop that does things properly take the reigns on Z H2 development.
Well that's not ZH2 anymore. It's naked H2R without carbon
If i can ship my bike to your shop ? How much it cost me to upgrade the cooler kit
Ok ,ma poi il motore quanto dura ? Non si rovina ?
How fast would this running a 1/4?? Man its a beast!!!!!!!
Moore says you'll grenade the cast imternals with those levels.....
i need this custom for my ZH2 ...
amazing, but I wonder what that does to the lifespan of the engine
I would assume it shorten its hugely
Can we see some h2r cams in a future vid
We have some cams to go in
Solid solid stuff. If you increase the fuel pressure by 10 psi and shorten the injector pulse width you'll make more power on the pump gas tune. It was probably having issues with atomization and not necessarily ignition. You could also decrease the gap in the plugs by a few thousands at a time.
Very impressive numbers however.
Plugs were gapped down, fuel atomisation wasn't the issue.
2018 R1 Supercharger!?!? When!?!? No one makes one! Why!?!?
Are you going to sell the patch harness
We can athough there is much more to fitting the Fueltech than just a patch harness, if you are interested you can email us though.
Hi I'm from thailand I want to see turbo kit for mt09 2022
That will be happening next year.
Omg
They made a ZH2R
I dont see running such an expensive exhaust for a couple of HP over an El cheapo. Any exhaust that removes the cat would work. Id rather get some head porting and ceramic wheel bearings. Maybe just a carbon fiber front wheel and ceramic bearings
So if the pistons look THAT similar, what in the engine block creates the higher compression ratio? Is it the head being shallower? thinner gasket? I can't imagine that piston alone makes all the compression ratio difference... I've watched the video back so many times and cannot see a difference xD
Piston shape and head chamber, these are factors that make the "famous" compression ratio, any small change in one of these points changes the rate drastically, either increasing the rate, or loosening or decreasing the compression rate.
a higher compression ratio, results in higher mid-range torque, lower compression ratio, less torque and longer engine life, H2 spins at 14,000 RPM, and has a ratio of 8.5, h2 sx 11.5 and spins 12k RPM
@@lucasreis7222 thank you Lucas. I didn’t realise such small changes make a big difference. I guess the head is different aswell since we know inlet and exhaust ports are different. I would defo take the higher compression ratio for better fuel economy. I’ve heard H2 owners get 50 miles per tank 💀.
I think Kawasaki overdone it slightly by lowering the compression ratio on the H2 a bit too much. They couldn’t have known people would change gears when it was released but maybe being their first forced induction premium bike they didn’t want to take chances.
The H2SX is a tourer so they had to increase it otherwise it would lose to other bikes.
I want stage 2 or 3 in mine once I got all the money saved but will be seeking a professional in this area to do the tuning.
@@09mantlek H2 is a very sensitive motorcycle to the temperature of the air box, if it gets too hot you lose 15-20 hp easily, in my opinion this h2 project should come with an intercooler, or kawasaki increases the efficiency of the supercharger, today the H2 makes 1.2 - 1.3 bar with original gears, that's a lot, it generates a lot of heat, the ideal was to come from the factory with 0.7 - 0.8 bar, it would generate less heat and keep the same current power.
@@09mantlek if i had a H2/H2 sx and i need a few more hp, i would upgrade the supercharger wheel, original is 68mm size, i would upgrade to 72mm, with original SC gears, you can add +- 30 whp or more, that means making more power and having a lot more efficiency, and I would add an intercooler along with a new fuel pump.
Why not just get an H2?
Wowwwwww!! That bike likes to kill you! 😅
OK
Kawasaki explicitly states they use a completely different supercharger impeller, different blade pattern
Well we have had them side by side & can see/measure no difference, marketing departments are known for telling lies when they think they can get away with it.
Like a H2R makes 300 hp 😂 thats one of my personal favourite Porkys
Using E85 !!?? Ahm... i understand it right... Benzin Mix with 85% Alc like E10, E20...
Nice exhaust. Way too high price. Cat delete mid system is fine. Id rather spend the money on E85 conversion. High compression and boost is E85s forte
Adding the H2 swingarm is a bad move for sure if you want to put the power down. Adding extensions to the factory arm is a much better idea. NO WAY are you using that much power with a stock wheelbase bike
Damn.... just when my savings account was recovering.
🤪😂😂😂 My first thought also, but it soon faded to "When can I buy the kit!!" 🤪
Why you so happy over a few hp more then stock? All that money for an H2R and all you managed to do is a few hp more and make it naked.
I guess you get a thumbs up. I like naked bikes
1st
1000cc SS bikes made this bike's torque as horsepower 15 years ago
Annoying BGM
