PS: They won't let me insert any links here, but here are the specs of the motor I am looking at. 18000Wt/750Wt(1hp)=24hp.


Product Description

12090 Brushless Motor

Brushless motor 12090 KV80
Spec:
MOTOR: 12090
KV: 80
MAX POWER: 15000W-18000W
WIRE WINDS:
MAX AMP: 200A
ESC: 250/300A
MAX VOLT: 70
NO LOAD CURRENT: 16,5
RESISTANCE (Ohm): .64
SIZE: 120 x 90 ( without shaft )
Stator: 40mm

Using those specs, I get (70v x 200A)/746 = 18.8 HP
