You may want to look at the 5670 -- Watts continuous: 6,500W
9S under load is about 36Volts X about a 185A = 6,600 Watts
This would keep you in a very safe range on the motor.

Gotta disagree about the 5670 vs 4070. The 56 motor is a big motor and fit could be tight depending on the hull. The 4070 motor is similar in size to a NEU 1527 which has for years been a good standard in 1/8's. The 4070 IMO is sufficient for a 1/8 scale, size, power and weight wise. Your assumed wattage figures equates to nearly 9hp gas equivalent! You can run at 100 amps and still be close to 5hp which is plenty for to make a 1/8 hull perform well.
