390 HP would be insane. Simply the fastest car ever. The brings is down to 3.8 LBS per HP. Insane. With only 1500 lbs on the ground, you could not get enough weight on the tires to get enough traction. Even an AWD system would be hard to get traction with that much power.
That is why my Escort will be very fast. Plus getting your but kicked by an Escort is like getting a swift kick in the nuts.
