I know a guy at my local track with a 99 Busa, 6" arm, geared to use 3 gears (strange), anyway, he has Bob's 210hp 'Head & Cam' combos with a Brock-Hindle pipe. The kid is about 165-170lbs, pulls 1.45 sixities and 3.85 330s and runs 8.80s at 155mph. I thought that was pretty stout. It cranks off 1 battery also.
I'm going turbo with my Busa, but Bob has his act together with all motor applications.
Good luck.
