Jack is right. The MPH tells the HP story, but the ZX12 was more effecient, putting the power down "better". This doesn't add up on paper, with the Busas longer wheelbase. Wait for more tests, the HP appears to be very similar between the two, but the Busa SHOULD produce lower ET's. My guess is that they were not launching very well, I'd like to see the short times for the runs...Tom G.
