Regarding Audis V10/V12 TDis in Marine application I know I know...

You live in vermont.....what the heck do you know about STYLE!!! :D :D

they came 3rd as wild card entry in the 2006 powerboat p1 british GP

Whatever you say Honey!

Here is a picture of my Vermont Yesterday!!! :drink:

I'll second that good luck with next years challenge

thanks,theres a lot of work going in to it so just hope its a good year,im apprehensively looking forward to it

Back in the late 80's we built 55 footer with a pair of those Diesels on Arnesons and it went to France, Nice Motors very compact ..the story I got is they were originally tank engines.

Buzzi spent a month with us in 84 or 85 ( Codomos place)he had the grey Iveco Cat going to Key West and was dialing it in ,Davy Wilson Knew him very well and invited him to our shop ,talk about an unforgettable person this guy was going at 6000 rpm ! Way cool experience I should have took his offer and went to Italy.

He was working on the Sea Tek then when asked "What If" they banned the new diesel the reply was laughing I got an Idea for a 500 cubic inch 2 stroke!!!!!!

Nice story there,

Ands that shows how the man thinks...never to get stuck on something.

Are you too old to move nowadays if the chance comes ?

Ps we ain´t prolly having a white christmas as the ther´s powerboats still running here this very day.

I got a few more projects left in Me LOL thanks for asking.

just had the new graphics done on xmas eve,waiting for the engine braces to be made then should be able to put the engines in .

Very nice! Looks much better than these (would take any of them though..):

As good as it looks in all thease pictures, it would still look better without the bow rail. The bottom looks very cool.

But the Buzzi "beak" is not up my alley , just as little as "Reggies"....

Olli's pictures changed my mind about his boat, it does look pretty good (not the pint jobs but the boat itself), BUT the rail has got to go!!!!

Joe Gere

An oldschool center rail instead.

yeah im not sure about the rails they may have to go once ive run out of major jobs,gona fit new battery boxes and new k keifer trim pumps tomorrow as the standard ones suck then rewire the whole boat next week as it was fitted with fpt motors when it belonged to the sunseeker race team.before the yanmars go in i guess i should take the trimax shafts out and check the bearings.hoping to launch by the end of jan:party-smiley-020:

What sort of FPT engines were used in your boat ? and did you buy the boat with or without these engines ?

The FPT,s are Cummins engines,I ve read somewhere that Sunseeker switched from 440 yanmars to 480 Cummins ,and lost a little speed....not sure why ,and like to know more about it.

Information given by Fiat Group regarding the FPT engine

http://www.fiat.co.nz/default.aspx?MenuId=207

This I assume the FPT engine spec sheet

http://www.ivecomotors.com/en-uk/Pro...P3D04N008E.pdf

Buzzi Used These N67 engines, although he tweaked them a little bit to squeeze more power for the Round Britain 2008 in the 46' ex Cessa boat Joe has often referred too, now re rigged from the original Seatek engines

http://boatdiesel.com/News/News.cfm?...FPT.cfm&Y=2008

Spec sheet

http://www.ivecomotors.com/en-uk/Pro...P3D04N009E.pdf

If they lost a little speed here would be my guess - the Cummins turned sower than the Yanmar and they used the same gear box and didn't gear it up to get the same prop speed back, they went with larger props not faster spining and lost a little speed - like I said only my guess????

i bought it without the fpt motors,my reasons are the boat seems to run better with yans,the yans are far more simple and easy to work on and the magic bit cheaper.i think with the newest p1 sunseeker that they sold to italy they changed so many things that the end result was a mixture that made it worse

Cummins/FPT 3000 rpm and Yanmar 3300 at top hp.
The governor kick in on the FPT at 3150 as stock at least.

They didn,t mentioned how much speed was lost ,but I guess it was very little ,but when they added more torque/horsepower ,the least expect was a little more speed.
but I do also think the gearbox they used with the Yanmar 440,s is the same box I use in my boat with the 1,30 in 1 th gear and 1:1 in second gear,and not sure if ZF offers taller ratio,s than 1:1 ,but I see what you mean with losing prop speed ,and maybe Scotty knows if they were using the 2 speed boxes with the FPT,s or not ? maybe they opt for a single gearbox with a ratio under 1:1 ??? if so the circle is closed

xs
 

i think they ran single speed boxes in the race boat ,i know it used to struggle to stay on the plane on the rolling start,they also added a chine/sprayrail to the rear that buzzi says is a no no.

So they wanted more sternlift ...,I wonder why ? the boats angle was ok,wet surface also,I mean ,its Buzzi,s design ,if the boat needed more stern lift ,he would have been added lifting strakes ,or could it be for the 125 lbs extra for each engine ? Nah

Now I begin to understand why the Cummins combo was a little slower.

Scotty,have you got the 2 speed boxes for in your boat ?

I would have said if they had trouble staying on plane, not getting but staying they are running steep OD gears. It's just like us little dia props lots of rpm can't carry the boat going slow and it falls off plane. With 1:1 gear and all that horsepower she would have large dia props and stay on plane at very slow speeds. Liken the small props to a large heavy outboard boat, they can run like hell but have no slower speeds, they either plow or up on plane running.

Why did they loose top speed? I just contradicted everything I thought was going on which was too slow prop speed!

I wish we had some data because it still seems to me the Cummins is 3,000 and the Yanmar is 3,300 and both should have about 150 in droop, right??? So, with equal gears the Cummins boat could be slower because the pitch they may have added doesn't equal the 300 rpm drop???

It's all speculation at this point but I can't see the two boats more than a couple mph's apart????

I can't see the race boat running 1:1 because that is just not Buzzi, all the boats ran OD's. Figure the math of how fast they go and what the engines turn and there are not props with enough pitch to go as fast as they go - this is basic math, no insults just can't be done with pitch.

Joe Gere

I bought 2 ZF 2 speed transmissions from Buzzi,they came out a xs type boat with diesels ,1,30 and 1:1 gears ,but it was a pleasure boat running 78 mph with 2 x 440 Yanmars,the owner changed to FPT power ,and I didn,t ask what gearboxes he were going to use ,If I calculate back from that 38 xs boat by knowing speed and ratio,but no slip and assuming the trimax to have about 10% slip,they must been turning a set 28 pitch props,so Joe ,assume he turned up the fuel on those Yanmars to have around 500 hp each and the rpm comes into the governer ,what will happen if you put on 1 or maybe 2 extra more pitch ? will the boat gain some speed now because nothing changed regarding weight,or less rpm ?

Are there manufacturers that offer overdrive style gearboxes ?
I,ve seen a PRM gearbox with 1:1,1 overdrive ,but thats not much ,and don,t no if PRM is still in business ?

I found on ZF,s page some gearboxes with ratio,s around .80 -.85 ,I guess I answered my own question :)

Better get yer finger out, or the "bombay bum basher" is on you!

td,when the braces are done its engines in,for those who are confused theres a bet if its not in the water by 7th feb when theres a small local race then i have to pay for a meal at an idian restaurant:cool:

We're rooting for you Scotty you can do it, it will be great to see the boat in action and better still it might spur on other P1 entrants to turn up

Going by your Avatar would I be right in assuming your XS was the boat used by Peter Dredge etc to set some endurance records around 2000-2001 time
I know there was an XS in the RB and CTC endurance events last year and I have always been surprised more XS boats have not become race boats as they do seem a good way to get out racing

No doubt the Yans wick will need turning up as the boat must weigh in around 4300KG+ and in order to achieve the optimum 4.5KB per HP around 480hp apiece will be needed in the SuperSport P1class

hi aquafun thanks for the support,the xs that dredge and co were in is dean gibbs one going lean,mine is sunseeker race teams pr boat .im gona change the pic know

The Curry Challenge
 

Oi, TD I hope you've got your BIG cheque book ready, its going to get some stick when we get to that curry house:evilb:

More XS pics
 

If any of you guys are interested, you can see a few pics from the day the boat was collected up to xmas eve when the graphics were finished.

So the exhaust is out both the strut and out the bottom by the bearing carrier??? Is the exhaust switchable because I notice the flap in the strut opening?

Very cool, I wish I could come over there with you guys!!!

Joe Gere

There were plans to start an own series. Unfortunately that never got off the ground:

good photo,s i havent seen those before.the exausts come out above the front of the shaft the flap above the p bracket is some kinda fresh air vent from above the deck at the rear.a friend took his seateks out of a buzzi today made my yanmars look like small generators:eek:

scotty,

Yes, the Seateks are BIG!!! On our 38 and even the Ganica early on had all the exhaust came through the strut. I'd seen many Euro diesel boats with and my own pleasure ones here in the States with just vent tubes for the props. Regardless of what Buzzi may say publicly the exhuast throught the strut did a couple things both performance and PR wise:

1) pressurized air to the prop which allowed them to spool up quicker to get on plane - instant slip not dependant on prop creating suction

2) it blended the exhaust with the water more throughly and made less of a smoke trail when you were running - the prop just grabbed the exhaust and mixed it into the wash

3) when you started the boat all the exhaust was under water, again less smoke

I'd seen some of the CUV's like Annabella that had a diverter valve on the exhaust similar to a Merc Silent Choice where they could divert the exhaust to the prop to get on plane and then change over to full through transom.

At the dock those boats smoked like hell but more important when they ran you could see the black smoke everytime they get on and off the throttle. With the Buzzi strut exhaust you hardly every saw smoke until we got the larger engines and went away from strut only exhaust.

I've been in there with Buzzi and I believe the lack of visable exhaust smoke leads people to assume that Buzzi didn't throttle the diesel boats. I say that despite what people think they saw I've seen it and done it and that is throttle the diesel boats much harder than a gas boat. With a gas boat you lift off the throttle to not over speed the engine and you apply throttle when you get load again - I know it's not that simple but it's the theory.

With the diesels when the prop left the water you needed to pump the throttle as fast as possible, as many times as possible from 3/4 to FULL throttle - why?

Because everytime the props loose bite (load) and or you pull back the sticks the fuel pump returns to idle and without fuel there is no boost. By pumping the hell out of the old mechanical pump engines everytime you go to full throttle for a breif second the rack lets full fuel to the engine - this keeps up heat which keeps some boost and turbo speed and when you finally apply power with the prop loaded again you still have some boost and can accelerate.

Nobody on here (OSO) seems to believe that but, why is Buzzi able to run his own diesel boats faster than anyone he sells them too - think about that - it's how you drive them!!!

interesting info ,as i,ve always raced a pair of merc outboards or a 496ho its gona be bit of a new exsperiance but it wont be for lack of trying .im looking forward to launch day even though daytime temp today was only 3degrees:cool:

Met a guy in the late 90's that showed me correspondence between him and either Sunseeker or Sunseeker sales regarding a one make XS2000 race series, however I just knew that it would not get off the starting blocks as racing I personally believe has never been something Sunseeker wanted to actually do

I reckon the idea of a Buzzi hulled tie up gave Sunseeker an exposure to the glamour associated with Buzzi's achievements without ever going near a start line plus there could be many spinoff's for movie's and advertising of which there has been

Sunseeker probably considered getting into bed with Buzzi a good idea as his boats were high profile achievers and an 80' Buzzi boat that had just done some record breaking sat right outside the Sunseeker HQ in Poole a bit of a poke in the eye to Sunseeker who wanted to consider the larger 80'+ motor cruiser market their domain and this could prove a large threat

So without ever going near a start line the XS was conceived with Buzzi a win win for Sunseeker a chance to snif the glamour of racing hang on to Buzzi shirt tails do some great adverts get into the movie's and who knows even a bit of record breaking for themselves never a bad idea for a company's products and profile and that has all been done :drink:

Thats exactly how you load up also Turbocharged gasoline engines if you wan´t to keep the power up (turbo spool).
Just watch any dragracer or WRC-rally car taking off.

And Yes Seateks are basically medium sized truck motors so ofcourse Yanmars look small or Cummins 5.9´s.
Put it next to a Cummins N14/855... :)

Years ago a friend of mine Raced a Cummins N11 with a Sisu racetruck and they had 1000hp easy out of them and wrecked the competition alltogether for a few years in Europe.
