Hi Chuck,
Sounds like a comprimise at first, but if the scenario is like you say
(given max possible boost at each RPM level) it could be made to
work I think.. If they work long enough with a specific pulley
and engine/cam/head combo, they could prolly end up with a "safe"
system, as long as the user doesn't change the variables,
ie; pulley size, cam etc.. It would tend to "go rich" if the user
decided to go to part-throttle (less than assumed boost vs RPM) while
under boost conditions, but it sure beats running lean.
Thanks,
Mike V
