Racing Oil Pump

Anybody know who markets a racing oil pump? I am involved in preparation of a race engine and the pump is wanted as part of the solution to address oil cavitation concerns. Thanks!

My company has provided custom oil pumps for race motors. They are usually not off-the-shelf items and they are mostly modified standard pumps for that particular motor. In any case, I am not aware that cavitation was ever a consideration, however, power consumption was. I remember that the BMW Boxer race motors achieved performance improvements by using modified oil pumps with lower power consumption.
What causes cavitation in your particular application? Cavitation can be caused by too high of a speed of the pump or a restriction in the inlet. Sucking air is technically not cavitation!
