Dailey Engineering Dry Sump System for VQ35DE

Description

When we last ran our Fontana Nissan Racing 350z, we were not comfortable with the quality of the oil pressure.  We decided to once and for all develp the ultimate oil system and put to rest any concerns about oil pressure.

We worked with Bill Dailey of Dailey Engineering.  Bill builds state of the art dry sump pumps and also builds the very best billet oil pans with the oil pumps mounted directly to the pan.

Bill’s design for the VQ35DE based engine integrates the aluminum main cap girdle directly into the pan.

By designing from the ground up, Bill was able to incorporate an oil inlet to route the oil into the block in the stock location, as well as provide ports for our engine oil temp and pressure transducers.

The oil pan uses the lates technology in controlling windage and separating the oil and air from around the crankshaft.

The pump is designed with roots type scavenge sections.  We expect that this efficient pump design will “over scavenge” the engine and should in fact draw in excess of 15″ of vacuum.

The overall package weighs about 5 pounds less than our old package.  The integration of the oil filter right on the pump is another example of this design from the ground up approach.

To fit the new pump with filter, we had to remove the old mounting boss from the block.  We also removed an unused boss from the block to allow easier access around the oil filter.  Both halves of the front cover were cut to provide clearance for the pump assembly.  To make front cover removal easier for cam or cam timing changes a separate bolt on front piece was used.

This package came out better than we could have hoped for.  The complete system is fully integrated.  It all looks so good that we now think the engine looks ugly!
