[QUOTE=Omerta;9014076]Depends on the method that its installed.

Option A:
Valve set to open when ignition is energized (As a racing sump would be) I would not add another quart as the entire purpose of the sump is to give a 1qt buffer to maintain constant pressure regardless of and reductions in pressure from the pump (high and sustained g-force turns).


no, no, no, no.
unless you happen to starve for oil at the pickup for an extended time and the accusump dumps it's full load, your motor will always be a quart down.
that is bad.
even when the a'sump discharges, soon as oil psi returns it rapidly refills.
i don't see our undertired porksters being able to pull enough G load to ever uncover the oil pump pickup except maybe, perhaps, a fully suspension done car w/ R compounds.
anyway, fill your engine with the proper 9.5 qts plus one (or w/e your A'sump holds) for the A'sump.
as always, it's both better not to wild guess on tech issues or trust strangers on the interwebs, so if you're troubled or doubtful, contact Canton.
their customer service is excellent.
