To say he will crash the car if he makes 500+ is retarded. You can drive the car as if it has 275hp. It defeats the purpose of the build to a certain point, but it doesn't mean you can't use the full potential of the car whether it be on he street/track. Not to mention, if you don't drive it with 500hp all the time than it will obviously "preserve" the car also.
1000hp supra>stock miata.......
