my motor will see <7k rpm, and is hyd.. nothing super fancy, so I normally would use a standard volume pump. BUT, i am also gotta supply oil the turbo.. so basically, i am asking if with looser than stock(say .0025 main, .0022 rods) bearing clearance, and supplying oil to a turbo.. will i have enough volume with a standard volume? not sure how much oil a turbo really uses..etc etc

 

Jordan: how big is the oil inlet in a turbo and where is the oil supply from? If the cross-sectional area of the oil passages is significantly increased a high-volume pump may be needed to maintain oil pressure. If the oil inlet is small (like a centrfiugal) I would get a standard pump and gain a few "free" hp.

yea, the oil lin is 4an, but there is a restrictor inside the turbo. I would guess its about like a blower in oil usage.
