I was reading on a older thread that a first gen was running a pump off a combine, and the truck rocked. Maybe we're looking in the wrong direction as far as the pumps goes, as in cranking the VE up, might have to look into different applications, industrial or agriculture. At work we have a excavator running a older B series 5. 7, I'll be looking at what kind of pump it's running, off hand I have no idea what kind of hp it has, can't see it being to much as it is a Samsung 210.
