720hp really isn't that crazy in the GT... even with the stock tires 1st gear traction is manageable 2nd gear the car just wiggles around a bit and by 3rd it's hooked up as long as your pointed straight. The power is SO smooth and the chassis predictable. I think with slicks you could comfortably run 900+ hp. Remember it is around 1,000lb heaver than a GT-40!
