Cheers Matt. Great link!! 
PS MAtt I don't suppose you can shed some light to the fact that my Yamaha engineer and many others insist that the 2-strokes VMaxes the 200 and the 150TRP (not HPDI) produce the 200VMax, 230bhp and the 150VMax, 170bhp. Something to do with this VMax technology which kicks in after 4000rpm.
Is this correct? |
Most motors are underrated ... I think bombardier even admits the ETEC 150 actually has 168 HP. Thats a little over 10% more. Not that we complain here :).
The reason for this is simply that in tests the "150" will shitkick other not underrated 150 HP motors... Also people will say brand such and such motors are stronger. Its just marekting....
If the VMax 200 is 11 % underreated then we are already at 222 HP so I beleive the claim, although 230 HP seems a little high.
I doubt this has anything to do with the VMax technology... I am not sure what it is they call VMax but I assume it is a tweak to the induction system...
2 strokes will work best at certain rpm where the air resonates properly through intake and exhaust ... At what RPM this happens is purely how the engineers laid it out. VMax seems to have this happen at 4000 RPM and more which makes sense for a "go fast" motor...
To make things short ... nothing extraordinaire here ... Peak HP is still peak HP (VMax or not) and the motors are still underrated like most other motors ....
