i'm the other guy that was there for the dyno run this arvo.. i was the tool holidng the video camera.
like tomj said, Tristan knows the 511 figure is incorrect, and also like tomj said, the thing effing moves, whatever they're doing down at SST is awesome stuff and no one should be bagging them just because you don't know how in the hell they hang it all toghether.
the video will be up asap to give you propper proof of the figures, and yes i think i'm allowed to say that more than one run was done, and all gave more or less the same result.
