Hi all,
Don't know if you remember my combo, but I've got a shallow V (Like a GN I guess) with a 565BBC and a 1071 blower running racing gas. Intercooled. 2x1150 dominators. BDS comp. manifold. Roller cam (284/293. .799/.765 @114). Pro-topline heads(360cc. ~410cfm@0.70). Blower is currently 10% under, Running 5lbs boost. The boat has run 95 at 5900 but was limited by the rev limiter. It should run 105 at around 6500. I guess its making around 1040hp at present. I'm currently running 33 gears and an 11.5 x 16 prop.
I want to up the blower to 20% over, which I think will give me around 16-17lbs. I want to maintain the 6500rpm limit and are going to change gears to suit.
My question is: If I'm getting around 1040hp now, what HP would I expect to see with 16lbs of boost, and, what gears should I go up to, to keep the RPMs at around the 6000-6500 mark.
Thanks.
Paul
