If it's a direct drive, it would interface like a supercharger with a drive belt. Not sure what the limits are for those drive belts. But adding 50 horsepower 746watts/1 HP
50HP=37300 watts.
Split that up into 4 batteries would be about 10000 watts per 12v battery or supercapacitor. 833 cranking amps per battery. All we would need is about 5 second max burst. If you used deep cycle lead acid batteries...this would add about 160lbs to the trunk which would probably balance the car 50/50. LOL
Just some rough numbers and thought.
Or in hub motors for the back wheels, and shorter runs of the wiring.
