hey, i am planning on changing my water pump soon. recently on my stock part checks... i found a high flow one and got me curious.
has anyone installed one or know more information?
i think the main difference is the open vs closed impeller discussion... but nothing super specific to our cars.
another hidden comment is most of the high flow pumps are some version of the wrx pump? but i don't know which one they are referring to?
anyways, pictures show open and closed impeller designs? i am wondering if there was just some marketing BS and people trying to sell the closed one has a super duper one? according to what i understand, gates make open... subaru makes closed... and there is no real high flow model?
thanks for any input.
