yea, no. dyno "1/4 mile" runs dont count for crap. there are far less variables. one guy tried to tell me he could run his bike in the high 9's at the track. and when i asked if he had he said "nah, but i did it on the dyno, same thing"
same thing? No, that mofo was strapped down. no flipping to worry about, no loss of control, perfect track conditions <well, conditions on demand>, no issues with traction etc.
thats why dyno runs mean dick compared to real life runs. I'd own an S2k, but i'm fat, and i could think of alot better ways to spend 30+ thousand dollars. but thats me.
