They break with the horsepower they have let alone adding more, would it be a mother or a bi***

I know. The V24 hull is the same as the B23 innit, with beefier wings & the canopy. A B23 runs 82mph on a single 200hp motor. IMVHO, a B23 with a single 280 would be quite enough of a beast (The goal being to go fast, not die)

I can't help thinking the B23 hull with 560 hp would be running well outside of it's design parameters - bearing in mind the B28 is on the limit with the 280's (hence why they trimmed it's wings and ran with a wing on the nose).

I also think OB's on a V24 would be detrimental to it's best feature - unstoppability in the rough. One of the key reasons why they're so good is the very deep drive keeps on powering through in the rough stuff. The motor is kept fairly dry as well so it can keep running even after a fairly significant stuff.

Does your current motor have ali or cast iron heads?

If it's cast iron, and you want to run "unlimited", I'd seriously look at either a big block with ali heads, which weighs within a cheeseburger of a small block with cast iron heads, or go with an aftermarket small block - it's quite achieveable to get 600hp without going to forced induction. You would then keep all the plus points of the current setup (Pretty sure the V24 has been described as the best rough water boat ever by Mr Little), but get a monstrously fast beast.

It has a different design than the V24. It is also heavier.

I think the V24 with canopy, twin 280's in the 6 litre class! That will be a mother of a ship!

I know they can go over 100mph.

If the layup was done properly (Something like Pascoe's V11 ) it does not break with a little abuse... It is something I would love to try. I would upgrade the canopy like on V11 and have the same build quality with extra suports etc.

I dont really have a clue on how to set up the engines though. I do know people who do, so that is a plus point.

If we added two 280's and removed the 5.7 and outdrive, I recon the weight would be in the same ballpark. The difference would be 320hp vs 560hp....

Potentially a very very nice package...

Mine personally, or all the other V24's?

I spoke to an engine supplier in the USA. They can squeeze stupid amounts out of a small block - There was a thread on this earlier... They were at one time topping 1200hp from a small block, but you had to run 118 octane.

You can easily get 640hp ( double the current HP ) using tricks and bolton gadgets....

The theory that double the HP = 1/2 increase in speed. So the current 80mph + 40 mph would give a scary 120mph estimated..

Would be a quick boat indeed with the upgrades but would it compre with the current crop of 6 ltr cats the bat struggled to find the speed to really stay in touch out there last season

They ran the B28, not the V24 hull. There is significant difference in the boat, and weight!

I do agree Matt I did think that an outboard may be less effective in the rough, I thought it may prove slightly easier to set up for the calm thou, perhaps balancing things out over a season, I thought perhaps the inclusion of outboards may widen the scope of it's appeal and you then have the choice of selling boat and engine separately. As regards the Ocke challenge cup I had thought in an ideal world yes he who has the most HP would win but I felt in reality as one famous Parrot man said...in order to come first.......first you have to finish and that may be the slowest boat

PS I did think if the Ocke teams threw in some cash and the idea was sold right to the designer, if he thought he would gain from it he may also throw in some cash, then it's only a matter of sorting out the best exposure for the give away

Don't forget the drive, and how much abuse that can, or can't take.

All is not lost! As it happens, one of the more imagainative RIBnet members worked out a solution to that very problem a few years ago:

Maybe, other than the weight saving all I know is that as they get hotter the valves and ports increase in size disproportionally to the normal heat related expansion and then return to their normal size by the time the motor has cooled and can be stripped for inspection. Amazing stuff.
