My boss owns Michael Schumacher's 1997 Ferrari F1 car.  It is *way* cool and
among numerous other goodies, has nitrogen-pressurized valve "springs."  I don't
know specifics other than they must be pressurized at all times or the valves
will fall into the cylinder and the head must be removed to untangle the ensuing
mess!

The rev limiter has been set back to 15k from 16.5.  I think this lengthens the
tune-up interval <G>.  It has to go back to the "old country" for any and all
work.
