I can agree with much of this but one of the surprises I've encountered in
life was near the end of my days with Ford. Several of us had the
opportunity to spend two twelve hour weekend days playing and learning with
certain engine builders about NASCAR engines and how they tune this
"antiquated" technology. NASCAR specifies carburated engines. One would
think after all these years that this would be a science that's long been a
slam dunk. Wrong. They keep learning all the time. Granted much of this is
finding ways to cheat on the rules established by NASCAR but beyond that
this old technology is constantly finding better ways to skin cats. I won't
ever say that something is etched in stone and forget trying to find some
way to improve on it. A few things brought to my attention at this NASCAR
weekend went against much of what I belived. I guess there is a point where
one should say " this is as far as we can go" but after talking and
listening to the NASCAR engine builders I'd say go back to the drawing board
and squeeze something else out of it.
