Dailey Engineering Oil Pumps


Dailey Engineering is the leader in dry sump oiling system technology.


Dailey Engineering oil pumps have a number of unique features that ensure optimal performance in the most demanding conditions. Every Dailey Engineering pump is designed and manufactured in house using the latest CAD/CAM software, and each part is CNC machined from aerospace billet aluminum and anodized for a durable finish.


Every pump uses a spur gear oil pressure section with a built-in adjustable pressure regulator for optimal oil pressure stability across the entire RPM range of the engine. Each pump uses a roots style two lobe aluminum rotor for maximum pumping displacement resulting in greater crankcase vacuum while still being lightweight.


Dailey Engineering has three lines of oil pumps “Standard Series”, “Classic Series”, and “SP Series”


The “Standard Series” line of dry sump oil pumps are based on the industry standard pump body size, ⅝” drive shaft, and have a typical pump speed of around 50% engine speed.


The “Classic Series” line of dry sump oil pumps are based on the “Standard Series” oil pumps and are the typical industry standard configurations for drag racing. Using new and efficient manufacturing methods as well as producing in large volumes has led to this economical line of oil pumps.  Now you don’t have to settle for a spur gear or gerotor style scavenge oil pump for your racing engine. For an economical price, you can now have a Dailey Engineering Roots Style Dry Sump Oil Pump built with the same quality and standards as their full line of modularly designed custom pumps.


The “SP Series” line of dry sump oil pumps is Dailey Engineering revolutionary design that was introduced in 2001 and allows a “Small Pump” with a body size of 2.4″ X 2.7″ to match the flow of their full-size oil pump. Combined with a weight reduction of 33% from the full-size oil pump, they have created a 6 stage oil pump that weighs less than 7 lbs and still outperforms other standard full size pumps on the market today.  This pump is typically running at 80% to 100% engine speed and can safely operate at pump speeds up to 10000 rpm.


Dailey engineering offers countless pump configuration options so if you don't see something that meets your needs on this site please don't hesitate to contact them directly.    


Dailey Engineering Oil Pans


Dailey Engineering designs and manufactures custom Dry Sump Oil Pans from billet 6061 T6 aluminum utilizing the latest CAD/CAM software and CNC technology.  With their “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.
