Default Real HP numbers
I just had my 90 XJS v12 on the dyno this morning so I could gather information on the condition of the engine. Is ran 232 wheel HP and with a rough calculation of driveline losses I think it puts it in the ball park with the factory figure of 285. Anyone else have real dyno figures?
