Keeping your racing engine suitably lubricated is a key component to longevity and proper performance. The majority of racers still use a wet sump-style pump for their car, so picking a beefy enough oil pump is important to keep lubrication where it needs to be. This quick video from Moroso shows their different wet sump oil pump offerings, and gives details on how to choose the best pump for your combination.

The standard cast pumps from Moroso will take a tube-style pickup that’s common on most applications today. These pumps aren’t your typical factory style piece, as they’ve been upgraded by the team at Moroso to work better in racing conditions. One of the issues that can occur with a spur-gear style pump is something called cavitation, which is the formation of bubbles in low pressure areas around an impeller. To combat this, Moroso has improved the pump with an anti-cavitation groove by enlarging the casting around the gear, allowing more oil to fill the pump.

The rigors of the performance environment can really test the durability of any product and cause failures. Moroso has made their pumps stronger by increasing the size of the necks on their cast-style pumps to prevent breakage.

Taking things a step further, Moroso also offers wet sump oil pumps that use a billet aluminum housing for additional strength. These upgraded billet pumps feature a built-in pickup, tighter internal tolerances, and the seam has an O-ring to improve efficiency. Moroso offers these pumps in both standard and high-volume units to give racers even more options based on their needs.
