Just got back, long drive back to Michigan! There was a ton of Busa's at the track, most of them were making 9.40 passes up to about 9.90 passes in general. One time I watched three go down one after another 9.8,9.7,9.9 so they were all right there in the high 9 zone. Some of them had air shifters, pipes, and arms but weren't running any faster than the stock ones! As for ZX-12's for some reason I never seen a single one at the track the three days I was there? I'm not sure were Michael Lee saw them, I guess I was to busy in the pits or just not paying attention.
