I'm not sure that a shorter stroke will get you that much more rpm. With a given burn rate, you're limited by time. Sure, you can get a bit of a benefit, but, I don't think you'll find any diesels with a torque peak much above 3500 rpm. There is just insufficient time for the fuel to burn.
Anybody know the torque peak for the new CDI's? Presumably, they've pushed this envelope as far as current technology will allow.
