I'd follow the manual if it lists a break in procedure. The first 1500km or so is usually ok, the most important thing is to get the oil changed at that point. Some companies still use mineral oil in the motors during break in and it doesn't do nearly as good a job lubricating/resisting heat as normal oil does. There can be a fair amount of metal in the oil at first as well, the sooner you get all that out of the engine after break in the better.
Drag racing is for fast cars. Solo 2 is for fast drivers.
