Im sure there no real way of knowing this but someone might know. Im just wondering if a 6.5hp engine @ 5500rpm would do it.

    90 amps @ 13v = 1170 watts, 1.34 horse power is 1000 watts so 6.5 HP should have no problem with that. But why in the world would you what to do that. What do you need that much DC for. Just buy a standard portable generator and a DC power supply.
