Please identify which Country you live in... this will help put things in perspective... Thanks!Mid December...right after the release to the public of the first orders.I would imagine anyway.It won't be long now
In the video they say that the H2 have a lower pressure ( I have read 20psi for the H2 and 35psi for the H2R) then the H2R and that is acomplish by the different instruction in the ECU so it look like if someone can hack the ecu we will be able to boost the pressure. Ricky Gadson's video seem to confirm that to. From what we know now it look like there is no difference in both H2 and H2R supercharger (same gear ratio).Link works but the video won't play.
The intake system has a bypass valve but its only function is to open when the throttle is shut, so that the compressor does not run nearly deadheaded in "surge". You could hear this in one of the early promotional videos that revealed the strange sounds.
This type of compressor is incapable of overspeeding - the boost pressure is defined by the intake air density and the speed of the compressor, which is mechanically linked to the engine. There's no need for boost pressure regulation, and it would be inefficient to do it that way. Kawasaki brags about the efficiency of this supercharger ... they're not going to engineer it to compress more air than the engine needs and then throw it away.
Obviously the H2 engine is restricted but I betcha they do it the completely conventional way ... Not opening the throttles all the way! It's ride-by-wire, so it's dead simple to do that.

This is a really good news: the boost is controle by the ECU and they talk about the clutch difference.
He did say..."according to Kawasaki".....heck...most of the reviews on these two bikes has been guessing anyway.Carefully worded guessing that is.To make it sound accurate and reliable.The REAL one to listen to is the man himself...Ricky Gadson...he's the one running the bike...and posting his findings.
That is a good point; it is entirely possible that the numbers being bounced around are absolute pressure (and somehow this was lost in translation - from Japanese to English, that happens easily enough). In engineering circles, "manifold absolute pressure" (MAP) is the standard way of referring to this.You know i dont get those psi numbers at all, they must be absolute not gauge pressure
as any 1000cc bike pushing 20 psi gauge with a well sized turbo or supercharger is going to be a **** of a lot more than 200hp
so if the h2 is 20 absolute or around 5.3psi i can see 200hp out of that no need to intercool and lots of room to upgrade
again if thats so and the h2r is running 20 odd real psi i would have expected closer to 400hp on an intercooled system, non intercooled must have a lot of timing pulled out to make it reliable ,
Or are we are still to find out the real numbers
