Katech developed their blueprinted pumps early in the life of their race program after noticing inadequate machining on the factory pumps.
The "blue pump" features a thicker scavenge section rotor to increase scavenge pumping volume by 30%. Data has shown that at high RPMs the dry sump tank oil level in the stock Z06 dry sump setup can drop considerably, resulting in oil starvation. This pump helps keep the oil tank level higher to prevent oil starvation.
