Product Description

ATOMIC Vernier Adjustable Cam sprockets suit BA-FGX - PAIR 

 

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/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 their 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 ECU’s can control the variable cam function effectively, 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.
