Just to add my two pennyworth to the canon of knowledge on Speed Championship power outputs, Northampton Motorport yesterday recorded 148.4 BHP at 7,300 RPM 115.5 lb ft at 5,900 RPM
Spec is dry sump 1600cc, Dave Andrews ported head, standard Caterham Supersport non hydraulic cams, 52mm throttle body, standard Caterham primaries leading to 4:2:1 Powerspeed collector and catalyst silencer, standard air filter
Out of interest in its heyday as a Roadsport A racer the original unmodded engine with no catalyst made 135BHP +- 2BHP at its many Minister rebuilds
