Re: Boost Gauge for A Rotrex Supercharger
no help I'm afraid, but do you think it would really be that useful unless you are involved in customizing the charger setup or something ?
AFAIK The boost will only depend on the rpm (the square of RPM for a centrifugal charger I think).
As a result you would pretty much already know (from previous seat of the pants experiences) just by looking at the tacho, how much the supercharger was working.
Its not like a turbo where you can have significant turbo lag depending on whether you dropped below a critical rpm.
