Read a thread on the forums about R6 cam swapping, and I have to say it's an interesting read to hear about the increased pull in the higher end of the rev range. I've noticed that most supersports pull harder and faster than the FZ6 by a fair margin - and I've been wondering what the technicalities behind this are. Honestly, I'd sooner buy an R6 engine and try to swap it out - but it's interesting nonetheless.
As far as I can tell, the gearing is likely different in which supersports have gear ratios that would allow for faster acceleration. I would have thought that different gearing like our 1st and 2nd being 2.8 and 1.9 respectively could have been something more like 3 and 2.2, and so on and so forth - but apparently the 03 R6 has identical ratios from what I'm reading. Why is it that they're revving higher to maintain the same speed as our bike? Camshaft profile? I know I can cruise at 100kmh and 5K RPM, whereas if I'm correct an R6 would be at closer to 6K to match the speed. How does a camshaft profile influence this, exactly?
I know their engines are setup with more higher end than ours, and once you hit the powerband the RPMs fly up drastically - which with differed fueling and ignition timing would likely go up even faster. That is of course changed by the higher up redline which if I had to guess would also equate to the powerband moving slightly upwards in the range and being that much better.
Any sort of insider knowledge on this type of stuff would be appreciated. I'd love to learn more about this kind of stuff, and you guys seem to know a hell of a lot about it.
