I got my information from Roger Wetherington - you know, the engineer who designed the systems?
He told me Hatt made two like mine, and concluded it was a fool's errand. However, they ran 25kts in the river behind the plant.
Look, the little 214 cubic inch six in my SUV makes 450hp, land speed bikes commonly make 2000 reliable hp out of a 1,000 cc four cylinder.
A 12v71 @ 1000 is agricultural in comparison.
