Craig has asked for the spec on the NME challenge rally cams that we now keep in stock. These are all new and not reprofiled second hand cams. They retain the standard base circle so O/E shims can be used if necessary. We do have some more blanks so cams could be machined to your spec.
The spec is as follows:
Inlet opens at 17 btdc, and closes at 57 abdc, dur 254, valve lift is 0.332 thou, valve clearance 0.010 thou, Valve full lift measured in crank degrees atdc 110 and valve lift at tdc 0.027 thou
Exh opens at 57 bbdc and closes at 17 atdc, dur 254, valve lift is 0.332 thou valve clearance 0.010 thou, valve full lift measured in crank degrees btdc 110 and valve lift at tdc 0.027 thou.
Rocker ratio 1.00 : 1
Overlap 34 Deg
Running standard base circle so standard shim can be used if needed.
These are not the wildess cams for a Micra but they do work very well on a standard ecu and things like exhaust manifolds and systems and induction kits.
