IT's SUPERCHARGED! NOT TURBO!!!
It has been reported, depending on the source as turbo or supercharged. MCN said its supercharged and I believe them.
look at the exhaust headers. Unless the turbo charger is way back next to the rear shock and the intake in routed back to the engine from there, this bike can't be turbocharged!
And supercharging isn't a bad thing. Potential for wild numbers like 500hp may be limited, but on motorcycles where smooth progressive throttle is VITAL, the lag free and most importantly linear throttle behaviour of a supercharged engine hold great advantage over a turbocharged one. A supercharged engine behaves as if its larger than it is all the time. A turbocharged one has a transition zone between its "large engine" and "not large engine" behaviour. Contrary to what all the owners of turbo bikes might tell you, that transition zone is hell on precise control of the bike in corners. You can learn to ride around it, yes, you can do anything. but if we are talking about ideal solutions, a 250hp supercharged engine is a far more usable machine than a 320hp turbo charged one.
Also, it must be pointed out masterful tuning of boost and fuel flow (on each engine individually) involving a very powerful ECU can yield brilliant steady state (lots of power) and transitional behaviour (no lag and predictable, linear throttle response) out of a turbo engine. But throw emissions into the mix and you're screwed. At least the manufacturers are. Motorcycles make throttle response and lag control even more difficult by the lack of rotational inertia in the engine. On a car engine, even if the boost comes on with a bang, a heavy crank and heavy flywheel soften its blow. On a motorcycle engine, too much boost suddenly means too much acceleration suddenly. You really want that?
I also want to address another point. I have a ZX-12R, and while mine hasn't been dynoed, most stock 12s dyno around 160hp at the wheel plus or minus 3hp. While most people are looking to get even more, and too much is never enough, I also know that I can rarely ride the thing full throttle unless I start at low rpm in high gear. My point is that whats needed is not more power and more speed. What would be nice is a supercharged 600 like the R6, and then not for peak power but to fill out its low end and bottom end.
I love big bikes because they start building serious power at 4000rpm and go beserk at 8000. If a 600 could get to about 120peak hp at the wheel but with a fat full torque curve (from forced induction), so that its already making 60hp by 4500rpm, and 100 by 9000, that would be perfect.
