Rover K-Series Q425HK – An hydraulic profile camshaft

Suitable for: Rover K-Series

Using a Q425HK inlet cam with a matching exhaust cam, this second stage cam combination is for more dedicated motorsport use. Although this is a hydraulic profile, the 0.425” lift requires the uprated VHPD type valve springs. To fit at optimum timing these cams also require pistons with deeper valve pockets. Using a standard cylinder head, 160* bhp is achieved and in a fully race prepared engine peak power should be approximately 170-180* bhp.

* The power figures quoted above are from dyno tests conducted by QED using the 1.8L K series
