We should probably call a spade a spade here. This is a 2-stroke motor. In today's powersports world it's normal for a factory 650cc motor to be putting out over 135HP. It's not impressive in terms of the performance to engine size and, as I mentioned in another comment, this engine will be extremely weak on the torque side of the equation which will make those ponies virtually useless.
- jacquesm 3y agoThat's fair, for a two stroke it isn't substantially better than what's out there. As for weak on the torque, for a generator that may not matter all that much. What I'm more curious about is the powerband, in other words how wide the RPM range is over which it produces max power. If that range is wide it might be a very useful engine (because you can simply couple it with an appropriate gearbox for torque), if it is very narrow then it really only will work well as a generator producing high frequency AC. That's one reason why specialty generator engines tend to run with very sharp cams on the camshafts: they only need to work in a very narrow RPM range and opening them earlier or later is just going to waste fuel so for maximum efficiency you want the valves to be open just long enough to take in enough air or to exhaust the expended fuel/air mixture. edit: apparently this engine also has a super charger, which isn't quite 'atmospheric'.
