The only way I see this having any REAL advantage would be if you're running directly off of the battery, which will help at the track but not on the street.
Now there is a chance that if you go to a full aftermarket pump it may be a more efficient pump all in all and would gain you some HP.
Just my thoughts....
Nevermind......it just dawned on me that it would help because you will be running the pump at a constant RPM instead of OVER driving it at high engine RPM. Probably cool better at high engine RPM too do to less cavitation.
