How much power would it take to make a 28 cig run 80mph?

I had a 1978 28SS with 280HP/350s, Merc 1 trans., TRS drives. She ran 60mph on her best day spinning 21p cleavers. During the 4 years we owned her I did a few mods to the engines, cams intakes, ignition. Maybe the engines made 325HP each. We ran 21p Turbo Vectors and 21p Mirages with max engine rpm @5200. The best we saw was 60 on the GPS. Tried those old cleavers and got 63mph at 5300+rpm.
Boy that boat drank gas but she was/is a wave crusher.
Anyway, I have spoken to many, many people about the 28' Cig including racers from back in the day.
IMO, twin BBC in a 28ss is a no no unless you want a boat that will have like 6" of freeboard.
I did know of a 28SS that had 500+HP BBC and TRS drives that vary fast for its time, early 80s, but man every time they lowered her in with the fork truck she looked like she was going to sink.
A fellow that used to race them told me that the best setup they ever had was with some screaming 6000rpm 400cube small blocks, 1.5gear TRS drives, 25p Mirage props. That boat went some were around 80...
To answer the question, my guess is that with the TRS drives it's going to take 500HP+ per side to hit 80. If she was rerigged with Bravos, maybe 450HP each.

Biggus has a friend with a 28SS who dropped in a pair of GM ZZ383 crate motors rated at 425 hp each. First report he was very pleased with the engines and said it really woke the boat up. No notes on speed increase though. Haven't heard any more about it since.

28ss BBC
I have a 1978 28 ss with a pair of closed cooled 454 mpi engines. merctrans trs drives. 27mirage props. As stated above it has almost no free board in fact when I leave it slipped up at the marina. People call to say it is sinking. I Have not had enough run time in the boat to get a gps on it myself. But the guy I bought it from said it does 74mph on gps saltwater. I have run against another boat that is know to do 68 69 and I can pull away from him if that helps. Also Judging by the way it pulls your cheeks back it feels like it is over 70. I will be sure to get a gps on it this summer. Brian

When is the Poker Run. I would like to get up there. I have three spares now but I may be interested in another. Brian
