Dailey Engineering is the manufacture of Roots Style Dry Sump Pumps used in high end racing applications. The company was founded 26 years ago by Bill Dailey, the father of famed offroad racer Pat Dailey.

They design pumps for the biggest names in racing including Joe Gibbs, TRD, Penske, Kroyer, Danzio, Andy McMillin, Cameron Steele, Josh Daniel, Johnny Greaves just to name a few!

A key feature of the Dailey pumps is their aluminum scavenge roots. These are up to 25% lighter then standard steel and also provide up to 50% more volumetric capacity and maximum crankcase vacuum compared to other dry sump pumps.

When you enter the parts room at Dailey Engineering you can see there is no shortage of parts kept in stock. They currently offer over 650 different configurations of their pumps and pans and while it would be impossible to stock every single part for every use they do have many of them in stock!

Dailey pulleys that drive the pump feature a taper grip locking mechanism that eliminate the need for set screws hence saving the oil pump drive shafts when adjusted or removed.

One of the most unique parts of the whole dry sump system is the custom oil pan. These stand out and lead the industry in design and quality. They are made from billet 6061 T6 aluminum. The key feature is having the oil pump bolt directly to the pan so there are no excess AN lines between the two.
