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

Dailey Dry Sump Oil Pumps are available in “Standard Size” (STD) 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 minimise 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. Between our two sizes of oil pumps we currently have over 1100 unique configurations in use today.

 

Aluminium rotors reduce the weight up to 25% over conventional steel gear and Gerotor oil pumps.  The aluminium housings and rotor combination all made from 7075 T6511 billet aluminium maintain a constant internal clearance over the entire operating temperature range.  Our two-lobe Roots Style design provides up to 50% more volumetric capacity, greater hydrodynamic sealing, and maximum crankcase vacuum than other dry sump oil pumps on the market.  Our aluminium rotors are available in either our straight or high helix twisted rotor design in some selected models.

     

 

Dailey Engineering 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, expense, and bulkiness of external scavenge A/N lines. Another benefit of the billet pan is the ability to design the internal shape to efficiently scavenge oil and control windage.  Our “Signature Series” modular design oil pans utilise 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.
