System One Oil Pumps

System One Oil Pumps: Race-Proven Lubrication Engineering

When engine survival is measured in fractions of a second, the oil pump becomes one of the most critical components in any high-performance build. System One has earned a commanding reputation among professional drag racers and serious engine builders by engineering oil pumps that go far beyond what stock or entry-level units can deliver. Whether you're building a weekend bracket car or a full-tilt nitro burner, System One brings the same uncompromising manufacturing philosophy to every pump it produces.

Cast Iron and Billet Aluminum — Built for the Application

System One takes a two-pronged approach to oil pump construction. The brand offers both high-performance cast iron oil pumps for Chevrolet applications and CNC-machined billet aluminum pumps for both wet and dry sump applications — including high-volume models for "Big Show" Top Fuel and Funny Car use. This range means racers running anything from a classic small-block Chevy street/strip build to a fire-breathing Hemi nitro engine can find the right pump for their combination.

Hemi Wet Sump and Dry Sump Specialists

System One racing Hemi wet sump oil pumps are engineered for high-volume racing applications and recognized as among the finest on the market today, employed by leading teams across many venues. These custom-made, CNC-machined billet aluminum pumps are offered with several options to provide the lubrication required for A/Fuel, Top Fuel, or Funny Car applications.

Hemi wet sump oil pumps are available with 1.8, 2.1, 2.4, 2.7, and 3-inch tall gears to deliver the desired volume (up to 50 gpm) and adjustable pressure — ranging from 80–125 psi up to 125–250 psi — for virtually every application from fuel-injected to nitro-burning supercharged cars. That level of tunability is rarely found in a production oil pump and reflects System One's deep roots in professional motorsport.

On the dry sump side, pumps are machined from 7075 aluminum with heat-treated steel spur gears, and all passages and chambers are computer-designed to help create maximum flow. Oil pump pressure is adjustable, and all pumps are flow-tested before shipping — a quality-control step that underscores how seriously System One takes reliability at the finish line.

Material Quality and Finishing

The attention to materials is evident throughout the lineup. Pumps are machined from billet aluminum and hard anodized for wear resistance , giving them the durability needed to survive repeated high-RPM passes. Fitment options span major engine families, including JP-1, BAE, KB, TFX, Indy, and Mopar big blocks , making System One a go-to source for builders working with exotic Hemi combinations.

Made in the USA

System One's complete line of oil pumps and related products is manufactured in-house at its Tulare, CA facility , ensuring consistent quality control from raw material to finished component. For racers who can't afford a lubrication failure, that domestic, in-house production is a meaningful guarantee of craftsmanship.
