I can't remember. Do the civics use a mass air meter?
).
That's what i was thinking. So much better.no they use MAP sensors
that all depends on the manufacturer, i have a conventional MAF setup (non blow through) and i vent to the atmosphere all day long with NO stalling or bogging issuesI can't remember. Do the civics use a mass air meter?
If so, with the meter in a draw-thru setup you can vent to atmosphere. If it's draw thru you'll have to vent back into the intake side.
All centrifugal superchargers should have a bypass (or blow off valve).
