If it was the blue 411 series 6 then I know the engine was bored out to 6.7l, has a special crankshaft, forged pistons, alloy heads which were skimmed, bespoke exhaust headers, an 'SS' sports camshaft Bristol designed specifically for it and a bespoke fuel injection system and an individual ECu. I don't know about anything downwind of the engine, although I did see that one of the Fighters at the 2010 Concours had a torqueflight fitted so they can definitely be made to handle somewhere in the region of 600hp, who knows how it is done?. I have been told by someone independent who has driven the 411 that it did 0-60 in a shade over 4 seconds on a slight incline. I am sure someone can reverse calculate the power rating for the engine? I think you just need the drag coefficient and gear/final drive ratios if you know the volume of the engine. I don't know the drag co-efficient for a 411 but for a 412 it is .4 with the winter roof on and targa in place, .42 with the summer roof down and targa fitted and .44 if completely open. I should imagine a 411 would shave a little off those coefficients.
