about 125rwbhp is the best I have heard of from a competition A series engine also. And I know the owner had spoken to John Taylor who confirmed it was similar output to his car. But that is nowhere near 200 flywheel. Its somewhere around 160hp at the flywheel, give or take a handful depending on the weight and type of driveline. And that gives realistic figures for competiton 2v engines of about 100bhp per litre. Which is exceptional for an ohv arrangement.
