Dailey Engineering specializes in custom Dry Sump Oil Pumps, with Roots Style scavenge rotors and spur gear pressure sections, for all levels of racing engines. Our Founder, Bill Dailey, has been active for over 30 years in the design of racing engines. With the design of several world class racing engines under his belt, he now focuses his attention specifically to Dry Sump oil systems.

Our Dry Sump Oil Pumps are available in Standard size and our "SP Series" small pump design. Introduced in 2001, our small pump design has a housing body size of just 2.4" X 2.7" with a weight reduction of 33% over our current standard size oil pump. Roots Style Rotors are used in the scavenge sections for both style pumps and bronze spur gears are used for the pressure section. Drive and idler shafts are made from heat treated alloy steel and precision ground to run in ball bearings front and rear with Teflon bushings supporting the inner loads to minimize the rotating friction. Precision ground stainless steel studs are used as dowel pin alignment for a compact body size. The scavenge sections are all internally cross ported together so only a few scavenge outlet fittings are necessary. However, to achieve the maximum capacity of our oil pumps optional scavenge manifolds with -20 fittings are available. This pump operates at speeds up to 10000 rpm in drag racing applications and 7500 rpm in endurance racing applications. Our latest revision to the Subaru EJ 4 cylinder engine. This design allows the hose ends to raise up 1.5" from our original design gaining ground clearance. Pressure inlet was moved to the rear of the pump along with a Brown and Miller custom scavenge outlet hose end makes this installation complete.

Dailey Engineering also designs and manufactures custom Dry Sump Oil Pans from billet 6061 T6 aluminium. With our "Signature Series" integral Dry Sump Oil Systems, the oil pump bolts directly to the oil pan thus eliminating the A/N lines between the oil pump and oil pan. All scavenge lines are internally machined into the oil pan eliminating the costly weight and expense of external scavenge A/N lines. Our new "Signature Series" modular design oil pans utilize a secondary manifold to mount the oil pump which also incorporates the integral oil transfer passages. This modular design allows the oil pump configuration to change as well as the position of the pump. This flexibility in design configurations allows us to install pumps that might be limited to the number of scavenge sections based on a sanctioning body's rule, clearance needed to add an air oil separator or to move the pump from one side to the other for packaging reasons. Just another tool to help in the custom design process and give customers get what they need.
