Very good info and a simple to do . But i dont meen to sound fick but when my motor did the crank i was told i only needed a standerd presser pump as im running about 360/380bhp and this was from a top tunner and a second top tunner said like you just put a standerd pinto pump in the motor and swop the lids over . So why do people need/use pumps with increased oil pressure . And wot was going rong with having to much oil pressure in your motor . Im not haveing a go im just very interested about this
