Atomic Performance Products - XR6T on-car Valve Spring Tool
On-car Valve Spring Removal Tool to suit Ford 6 Cylinder DOHC
Our Patented (Patent # 2006100221) tool is a simple device to facilitate
quick and easy removal of valvetrain components in Ford 4.0L VCT twin cam
Barra engines. The unique features of the tool are as follows:
• The cylinder head does not need to be removed to gain access to the
• Once the tool is fitted, all 4 valve springs per cylinder can be
• No special skills are required to use the tool
• The possibility of collets falling into the engine is greatly reduced
The tool saves many hours of labour when changing one or many valve
springs, valve stem seals or retainers - a mechanic can change all 24
springs in about 3 hours. Changing valve springs is very common due to the
varying tensions of standard springs and their rapid deterioration in
service, which in turn caused erratic idling and drivability issues. They
are also regularly changed in Ford turbo
vehicles as higher Boost can bring
about premature valve float.
To use the tool, simply remove the camshafts, fit the tool to number #1
cylinder and the 4 springs can be changed in about 10 minutes. Refit the
tool to the next cylinder in sequence and continue until all are changed,
refit the cams and the job is done!

Atomic Performance Products - XR6T High Performance Conrods
Atomic billet steel conrods were designed from scratch with one principle
in mind; use aerospace quality materials and sophisticated manufacturing
processes to produce an extremely strong, light and durable connecting rod
for the popular inline 6 cylinder Ford SOHC/DOHC engines, at an affordable
The Design and Evaluation Process
The Atomic engineering team set out to address these parameters by
designing what many performance engine builders are now calling the finest
conrod on the market for the Ford DOHC 6 cylinder engine.
Extensive CAD/CAM computer modelling was employed and produced a H-Beam
design, which has an extremely high stiffness-to-mass ratio. The next step
was to pick the correct materials, heat treatment and surface treatment
processes to ensure durability under rigorous performance applications.
Next came FEA modelling (Finite element analysis) to simulate stresses on
the conrods. This also entailed weighing every piston, gudgeon pin and ring
set on the market and loading this information, plus stroke, rotating and
reciprocating conrod values into our computer modelling software to
calculate the stresses.
The greatest load exerted on a conrod in an engine producing 600 comes not
from the force of normal combustion but from the tensile force exerted by
the piston at top dead centre (TDC). At 5250 RPM the piston exerts a
tensile load on the conrod of 1908 gs (-1693 kgs) at split overlap TDC
reversal. If you increase maximum engine speed by only 1000 RPM to 6250
RPM, the TDC tensile load rises by 50.4% to 2870 gs. At 7500 RPM the
tensile loading increases to 4132 gs, clearly demonstrating the Atomics
design strength of 8000 gs means it has plenty in reserve.
Excessive loads at TDC are brought about by a high reciprocating mass
and/or by increasing engine RPM, so it is essential to design reciprocating
engine components with the lowest mass possible to minimize premature lower
bearing shell bearing failure. This is particularly relevant to our
customers who are turning their engines to 7500RPM+.

Atomic Performance Products - XR6T High Performance Oil Pump
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.
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.

Atomic Performance Products - XR6T Vernier Cam Sprockets
The Ford DOHC 6 cylinder engine has hydraulically adjustable camshaft
timing which is controlled by the factory ECU. The factory tuning retards
cam timing (of both cams simultaneously) at light throttle above 100 KPH to
aid emissions and fuel consumption and subsequently provides no advantage
to the performance enthusiast. The VCT units do not allow the cam phasing
to accurately follow the crankshaft/piston motion as closely as is
required, which brings about tuning and fault code logging issues.
Proficient tuners know that accurate cam phasing is critical to extracting
maximum power from a given powerplant, so we designed and manufactured
adjustable cam sprockets to allow tuners to maximise the VE of every engine
Another advantage of our Vernier sprockets is that it eliminates the
requirement to retain the original Ford ECU and harness when transplanting
the DOHC engine. Very few aftermarket ECUs can control the variable cam
function, so with this requirement eliminated a whole world of
possibilities of retrofitting the DOHC engine to earlier vehicles becomes
available to the enthusiast.
Atomic vernier sprockets are CNC machined from 4140 chrome moly steel with
the outer section of the DOHC sprockets gas nitrided for maximum
durability. Secured together by four hi-tensile allen head bolts, timing
adjustment is quite simple due to the degreed markings on the hub. A full
36 degrees of movement is provided, allowing the professional engine
builder a huge scope of adjustment.
Atomic timing chains for the DOHC Ford 6 cyl are more than 80% stronger
than the stock chain for use with heavier than standard valve springs. They
feature roller trunnions and 1.7mm thick link plates to provide the utmost
in reliability. Will fit with standard or aftermarket sprockets.
