An absolutely phenomenal feat. Congrats to Bill and his team from everyone in the LSR community.
IIRC, he's running a heavily modified 'Busa engine/drivetrain, turbocharged with progressive boost
controller around a handbuilt streamlined fairing... He went 273 last year, but that was due to breaking
something at around the mile mark, drifting down to 273. Bike guys, correct me if I'm wrong...
