Ninja H2?

Yes of course.
The car industry has clearly proven that commercially viable turbo engines can have the best of both worlds, but I think that given the design constraints in a mass produced motorcycle, that Kawasaki has made some smart choices with the gear driven charger.

It boils down to $ per HP. How much do want to spend? :teeth

too much hype for something with such a limited run (rumors of only 500 units)

they should use that hype to sell a crap load of good ole' production bikes, instead of 500 halo bikes that would have sold on the tech alone without any hype.

i really hope it's not just 500 bikes

i can just see now... tune, pulley, exhaust and that thing is on the heels of 300whp without any engine work.

Again, I have often been wrong ...

But, developing the technology for a production run of only 500 bikes does not seem like that would be a sensible decision for a large company like Kawasaki.
They might have a first run of 500 limited edition bikes, like their 30th anniversary bikes, but the fundamental technology has to be relatively inexpensive to mass produce, and incorporating it in future generations of bikes seems to be best way for them to get a return on their investment.

In other words, I do not think they picked a solution machined in unobtanioum, but instead adapted known technology that can be manufactured without lots of individual tuning or manual production steps.

It should be pretty obvious by now that I have a lot of respect for Kawasaki, and that I really like forced air systems in general. With that in mind I still think that the solution points towards something that will give a significant boost and/or weight reduction compared to the competition.

I hope that we will see a whole portfolio of blown bikes from Kawasaki.

Electric superchargers are an unnecessary complication.

Well - I might be, and I have fallen flat on my face before.

But controlling electrical motors and solenoids is something I do a lot, and in my world being able to react quickly to O2 sensor, pressure sensor, and encoder input is the name of the game.

I believe that there are advantages to the fine grained control that can be obtained by running the blower on its own electrical motor, in terms of ramp up of air pressure, and control of a desired air pressure for a given engine load.

I am putting my own time and money behind the work I am doing on this, and it might end up being a big joke on me, time will tell.

Well, working with turbocharged engines is something I do a fair amount and if electric superchargers made sense, it'd be on production vehicles already. Fuel metering is much more sophisticated as boost is already easily controlled.

Problem with electric superchargers is that you need a substantial electric motor to power the thing and a somewhat sophisticated controller and feedback loop to vary boost rather than using currently available turbo tech. Plus, you put a huge current load on your charging system trying to spool up an electric blower very quickly. Remember, turbochargers turn 100k to 250k+ rpm, depending on the size. That's a lot of torque on an electric motor to turn a supercharger that would produce similar flow and pressure. I wager you'd have more lag with an electric blower than you would with a properly designed turbo system, unless you had a multi-stage, multi-supercharger setup, which essentially renders the point moot. I dunno, just doesn't make sense to me. Turbo or mechanical supercharger is the way to go.


Side note: A Top Fuel blower requires hundreds of horsepower to operate the blower at max rpm. Even a street engine at modest boost could require over 20hp to turn a blower, if not more. The returns make up for that loss, but go size a 20hp DC motor. Plus all the electrical upgrades you're going to have to do in order to drive it. A typical car or bike is not set up to handle that kind of electrical load. At that point, you may as well just make it a hybrid and go from there. Oh, and turbocharge the thing on top of that, ala Porsche 918, et al. :D
 
Wahoo, cool setup! Looks to be a substantial turbo for that size engine. How much boost you making? Got any other pichurz? :D
 
you know what would be even more annoying

is if they take pre-orders on 9/30/14

but dont deliver the bike until 2016

like that fooqn desmosedici nightmare
 
yea 2x versions confirmed by the guy whose been riding in all the videos,

1 street, 1 race, with full options = $50k

hopefully the $50k example is limited to 500

i think base is gonna be $26k

That's a lot of cabbage for a first time out blown modern sprotbike.
I think I'd rather have the HP in all motor NA for that kinda dough.
