The only thing that'll go 200mph is a full on pylon racer...go watch one of them sometime and see if you could handle it...you won't!

As with anything, you have to start out slow (in this case, literally!!) and work your way up to new levels of proficiency or you'll be a danger to yourself and to others. This is just advice, I'm not knocking your aim for speed...just go into it gradually. But when you get proficient enough be prepared to spend lots of money on an engine because it needs mega HP to go that fast...you won't do it with an OS!!
