BlueGTS, Yes I did read the Origional!
I interpret, "a lot of 30 to 150mph racing", as open track road racing where exit speed is King and will out, accelerate, run any $1,000 worth of HP gain, any day of the week.
Perhaps he did mean 30 to 150mph sprints. But I missed the sprints part of the post. And anyone driving a Viper will benefit from a high performance driving school, but doing 150mph is to be done with respect and High Performance driving experience.
The attempt for an analogy speaks for its self.
