Stage 3 Supercharger gears on Kawsasaki ZH2 Extreme EP2

Join us in episode 2 of our ZH2 Extreme development series as we fit a Blow off valve for some boost noises, Powercommander PCV, ignition module & overdrive supercharger gears for some more boost.
We also test & compare Ninja H2 injector flow rates to the ZH2.
The turbosmart BOV can be purchased from our store

following this project so when I finally find a ZH2, I know where to get my parts! Great job.

[@Speedyey]

might wanna take a look at brocks performance ;)

[@scott02127]

Showing the bike being taken apart was f' n awesome! Thank you for uploading this video. Best practical maintenance video I have seen on the zh2. You Rock! I own one and was so cool!

[@joffinbob]

Wow, that bike is gonna haul ass when someone finally cracks the ECU. I’ve been waiting for the second video but this was worth it. Can’t wait for episode three

[@thehoot55]

Really enjoyed the video Ben. I installed the turbosmart blow off valve and love it. I agree it is a fun bit of kit. My hand was small enough to get in and remove the tubing from the stock blow off valve and put the bung in without removing the ram air tubing.

[@jpbsv]

Good to see youre advancing the cause.... i'm on standby credit card in hand.

[@coreymott2256]

I cant what for someone to crack the ecu so I can get my brocks exhaust, tune and a bov things already stupid fast I can only imagine! Keep up the great work!!

[@GGGMotovlog]

Underrated channel, this is nice one.

[@66garagecilacap]

Awesome!!! Can't wait to get my hands on the Zh2. Great knowing there are people already working on making it faster 👍

[@InteractiveIdea]

I m doing the best upgrade to this bike this winter. Suspensions! Followed by an air filter and a flash. Exhaust slip on is already on. And that's all you need to really enjoy it

[@Benjay1975]

im not going to lie, the standard super charger sound, sounds way better than that after market blow off, it sounds like someone is chasing you with a bike pump lol

[@bigb27me]

Nice work! Very impressive considering u dont even have access to the ecu for flashing yet. Not to mention that you're dyno is 20-25hp lower than Dynojet's like on Brocks performance's dyno, you'd prob be closer to 225hp already. Can't wait to see the intercooler / stage 4 results & hopefully the ZH2's true potential one of these days, once that ecu finally gets cracked!! Awesome✌

[@Gypsyjoe67]

Serious, professional dudes, they really know their stuff and bought their bike from the same dealer and Salesperson I got mine from a couple of months after them! Stage 4 with inter cooler, jets, BOV and cracked ECU, etc, etc will be basically unrideable at full throttle without an extended rear end, but still, I cant’t wait to see the Dyno runs and to hear the pricing per stage, my guess for state 4 is around $12-15 K ???? Put your guesses in, see who comes closest, to be fair just name one price, mine will be $13k (let’s just do stage 4 for now). PS. Mine is already enough for me with Akra pipe and DNA air filter!!! Happy bidding!!!! 😀

[@dogdtwo]

Can't wait for the intercooler

Stellar instructional Professor'

[@propheticpig868]

Wow, massive gains. Very impressive ! That bike soooo restricted by the manufacturer

[@DeltaElite121]

Never seen your videos, but this was an awesome video. Great seeing more of the internals on this bike and a dyno to reflect on the changes I was hoping someone would jump at. Thanks for a methodical approach to making power with this bike; I might have to give it another look. I'm still wondering if they're going to address the heat-soaking issue by offering an intercooler in the next few years, but I'm doubtful.

[@HoonTV]

Cool!

[@zedzh2371]

Awesome vid!!

[@kevinmill7965]

What about posting Torq graphs at each run to...

[@postmortemspasm]

Screw waiting for the ecu to get hacked... make a cable kit for the throttle. Im sure it could be done

[@MJ-rr4hd]

so the super charger is under the seat. do you think it would be better if the intake pipe was in the front?...cause thats where the cool air is.

[@tupacshakurrr9905]

how is it possible that zh2 delivers 200 hp as standard according to papers. measuring 160 hp it is a big difference??

[@meljanmaturan2774]

Dito pala yooon, nice naj abdul

[@Moxyator]

Excellent video passing on some very interesting information. The first run showed 162 ? I thought they were 197 as standard or is that humidity and temp etc affecting results ? Finished with out an air filter at 206 wow what a result.

[@1fast5.0]

Hello! There are 2 hoses on the bottom of the gas tank, when you eliminate the purge valve and canister, what do you hook to the other nipple on the bottom of the tank that used to go to the purge canister?

[@truckingandstunting8538]

That BOV would be so annoying after a while. Just sounds like you have a leaking tire.

[@DoRC]

Wouldn't those technically be sprockets?

[@Steve-pv4ym]

What's the benefit of using your blow-off valve vs just removing the stock blow off hose and caping the intake?

[@bobbyblueace]

This is super interesting. No mention in the video but have you also been adjusting the fuelling via the PC-V to support the increased boost and injector change?

[@extcreat]

Yes every boost change requires adjustments to the fuel map

[@richardwoodhouse8397]

Hi" I'm about to fit manual c.c.t & s.c.c.t on my H2 2015 what with the recals & failures, considering your tuning them is there any particular reason why your not doing the same?

[@stevennelson3711]

What size of carbs does the 2020 zh2 have? Kawasaki says 36 and 38 on their web specs. Brock's says 40mm that kawasaki made an error on site. Brock said 40mm just like th he h2sx. Can someone tell me I do believe Brock's.

Adding just a slip on would i need a power commander or just leave it?

[@jeffrakunas663]

Do you have a link for that SP slip on or a part number? I want to make sure I get the same one.

[@SBK_SUPERBIKESKIT]

May I ask for the number for Ramp rate you set for Dyno dynamic?

How similar is this to the H2 sx se ? I’m building mine ( 2018 H2 sx se)

[@MRtheattitude]

Question: I am interested in the stage 1. Is it possible to change the upper gear through the upper cover, so without to open the clutch cover and remove the clutch assembly ?

[@extcreat]

no you can't get enough slack in the chain to remove it, clutch has to come out.

[@KonstantinGabriel1978]

Așa Don Guhl about unlocking the ECU. He managed succesfully to optimise it. Look it up either on FB or google. He is top notch

[@extcreat]

Guhl is one of the companies working on cracking the ECU

[@KonstantinGabriel1978]

My 14R ,zx10Rr were completely different beast after reflash. Well worth it.

[@lav1daloca]

If they can get 300hp out of an H2 I'm sure you can get 280hp out of the Z2.

[@robertdaone]

There are actually some H2s pushing close to 400hp now. If 300hp or close to it can be squeezed out of this bike I will definitely buy one because it would be a bargain.

[@yanroeung6289]

What kind of exhaust is that ?

[@user-ko4pj7ir6e]

Looks good I just don't understand how come you put stage 3 on it while the compression is 11.8 super high compared to h2sx 11.5 and h2 8.5 when the ecu will be able to flash and etv could open 100 and rev limit raisd maybe the engine won't handle it and big chance of detonation.. what you say about that? And you just add 2 degree ignition 8000 to limiter at 100%? Thank you

[@extcreat]

ZH2 & the H2SX both have 11.2:1 compression, we are more interested in adding torque earlier than reving the engine harder as thats where most people will see the biggest advantage, of course we will make adjustments once the ECU can be flashed. This video was to show the difference to boost levels the gears make & to see what gain we can get with an ecu that still has the restrictions in place.

[@user-ko4pj7ir6e]

@@extcreat ok sound good How much ignition degree you add and where? And you sure 11.2:1 compression?

[@user-ko4pj7ir6e]

@@extcreat and btw the upper gear is 0.5mm wider than h2sx upper gear.. did you measurement both and check because i heard that they are different, And you adjust fuel to 11.5AFR? Thank you!

[@extcreat]

@@user-ko4pj7ir6e Gears are the same thickness

[@hnic72]

@@user-ko4pj7ir6e the only way you can believe it's 11.8/1 is because some dimwit on the zh2 forum made an absurd claim that the z h2's c.r. is 11.8/1. Now stop and ask yourself this question for a second.. Do you think Extreme Creations, that has worked on this supercharged Kawi platform for years, is unsure of the compression ratio?? It's you that's unsure, my friend. Take the info and move on. There's no need to ask the same question numerous times.. It's been answered already
