Street Fords DVD - Barra Strip Down

From 2007, host Racin' Jason strips down a Ford Barra (XR6) engine, then catches up with Brad from Atomic Performance Products about their aftermarket parts.

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 valve springs • Once the tool is fitted, all 4 valve springs per cylinder can be changed concurrently • 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 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 combination. 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.

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.
