An old concept that seems well suited to Direct Injection.

If you scroll down you'll see a prototype Norton Wulf utilizing this principle:

Weird. Seems a bit low on performance for a 580cc motor at 50hp, but at 40lbs it more than makes up for it.  Whats cool is that motor at 6 liters would produce 500hp N/A with an ungodly amount of torque at 413lbs with 41 cylinders.  ;D
