Oil Pumps and
Components
High performance Ford 6 cylinder DOHC engines
need a high performance oil pump - and Atomic
has engineered the answer. We produce high
performance billet steel oil pump gears as well
as complete race-prepped oil pumps for the Ford
DOHC engines.
Ford DOHC, 2J Toyota and various Nissan oil
pumps are Gerotor design pumps which are driven
directly off the snout of the crankshaft and
subsequently are subjected to twisting moments
that increase substantially with RPM. These
torsional forces cause the oil pump drive gear
to be thrust clockwise and anti clockwise, which
eventually leads to the failure of the gear. The
torsional moments are of a higher frequency and
greater amplitude in manual gearbox equipped
cars due to them being “on and off” the throttle
more often during gear changes, downshifting
etc.
Ford DOHC 6 cylinder oil pumps fail for 2
reasons: The original equipment (OE) gears are
made from powdered metal and lack the structural
integrity to withstand the stresses created in
high revving engines. Secondly, Gerotor pumps
produce pressure and volume almost proportional
to engine speed, so high revs equals higher
volumes of oil. These larger volumes cannot be
adequately managed in a standard oil pump and
hydraulic oil pressure can split the pump body
open (click on image>>).
Atomic Engineers addressed both of these issues
when designing an oil pump for performance Ford
DOHC applications and subsequently our pumps are
designed and tested to 7500 RPM and beyond.
Our #306751 and #306751-RB oil pumps features
precision cut billet steel gears, high flow
pressure bypass circuitry, fully blueprinted and
clearanced and also include a hard anodized
billet end plate to provide thrust wear
resistance.
