I'm just happy my boat does four of the six in the poll fairly well. 31ft AO cat. Twin 509 cu. in. with B&M 250 blowers. The wife wouldn't allow scoops on HER sunpad, or I'd have used bigger blowers.
At the time there were no gears available for Bravos taller than 1:36 or props larger than 34 pitch, and after a few runs in the Shootout of 122mph at a little over 6000 rpm, one of the hydraulic cams gave up the ghost and broke in half.
I then went with flow ported Dart alum heads and full solid roller cams that pulled strong well above 6000 rpm. Changed to Manley H-beam rods also at that time in anticipation of the higher revs. These cams idled great at 900-1000 rpm and go to 700-750 rpm in gear.
Then I bought the smallest upper blower pulley they had. These little pulleys gave it a real nice blower surge, though not as good as the bigger blowers at high boost.
So my best Shootout run to date was 133mph. I had 6800 rpm chips in the MSD box and I remember as I was approaching the radar gun that I thought it was going to hit the limiters, but it didn't. Them little blowers were screamin'. I also run the exhaust dry for Shootouts.
I got a lot of compliments later about how good that thing sounded coming up the course. I guess after an afternoon of listening to many of the participants buzzing them through at 5200-5600 rpm, hearing a blown BB screamin by at close to 6800 rpm was a little refreshing. Or as I heard, "that's more like it".
For me though, my vote goes to that big azz cam idling, especially with the dry exhaust
