correct, still needs gone thru every 50 hours ACC to merc !!! WOW

i love wet sump..its not that much less gain over drysump..!

less breaking parts and more reliabilaty !

NOW, back on topic ...or they say its my fault again...LOL

hope that helps !?

Peter, LOOKING VERY NICE !!!!!

Sorry, but that is just another of the B.S. stories from Weismann. They did not invent nor found dry sumping, rather the Victory team would run qualifying laps with no oil in the MK6 and they had the idea and put it out there. Prior to this even team Gentry in Los Angles, dry sumped the Mk4 and MK5 well before Weismann could spell but they are not going to tell you this of course.

Some how I really don't think you are going to get a reply Boatless-Again. !!!!!

No, didn't really expect one, rather tired of hearing the unthruth. MY VW/Porsche has a drysump motor, did weismann invent that too?

DAREDEVIL · 12-08-2011, 10:56 PM

Hey, sorry....just seen this . OK HERE I GO !!!!!!!!

R E P L Y !!!!!!!!!!!!!

now back on track with this nice boat here !

Hi All,
I am now back in the harness after a very hectic two and a half weeks down at Hamble Point working on a triple engined rib. While i was away the water flow gages that we ordered from Livorsi at the Miami show in February finally arrived as the castings that carry the paddle wheels were rather thick and heavy i decided to machine them all over to reduce their weight and make the internal bore the same as all the other Ilmor fittings, as they need calibrating anyway it shoudln't affect their performance.

Triple engined RIB? Any more details so share?

GaugeThis · 18-08-2011, 08:23 PM

Thanks Peter for the nice post. This Livorsi Raw water flow system can warn you of potential dangers for you headers, impellers , sea strainers or intercoolers. Water pressure is not the same as Water Flow.

Best Regards

Hi Petter,
Can't say very much about the rib other than it weighs 13 tonnes and we fitted three D6 370'S on DPR drives and it did a very creditable 50 knots two way average with a little bit more to come by tuning propellers.

Hi Peter

Was just looking at you flow gauge and on Livorsi web site. Just wondered if there is a signal from the engine to mach RPM to expected flow rate and if so how does it get its signal from the engine or is it just very clever and works from the flow sensor alone.

Hi David,
The flow gauge takes a signal from the taco trigger wire so once calibrated you can spot a problem at any rpm.

peter when do you think,the boat will be finished/ready for sea trial ?

peterunwin · 19-08-2011, 05:04 PM

Hi All,
The NAS bolts and K nuts arrived for the driveline so these have now been installed. Also purchased an old floor standing polishing machine should have done this at the start of the project as i have knackered two pistol drills doing the polishing up to date and i only paid £130.00 including a good selection of polishing mops and several sticks of compound and being three phase and 4HP you can really lean on it so polishing is much quicker.

Hi Carl,
Early next spring provided i don't take on too many other projects!!!

Peter

cheers,must be killing you waiting till then

I'm assuming it won't work on a diesel then!

Hi John,
You could use the W connection on the alternators or failing that i am sure Livorsi would be able to supply a CAN Bus interface.

Is there not a pulse type pickup on the flywheel housing reading of the ring gear? There was one on the VW Marine TDI 225-6's we had. If there isn’t one fitting one should be relatively strait forward and cheap.

Hi All,
I have been unable to find suitable hinges for the clamshell engine covers so i decided to make a steel pattern which has now been delivered to Carbon Weezel so they can make a mould and manufacture the hinge parts in carbon fibre, i will then mill in the slots and bond one half to the boat and the other half to the engine hatch using the left over titanium rod from the steering transducer installation to form the hinge pin.

Peter

peterunwin · 05-09-2011, 01:26 PM

Hi All,
Collected the prototype carbon fiibre hinge which we will experiment with to find the best machining method, also made a couple of aluminium bessels for the water flow gauges these are to cover some damage that was done in transportation.Have also cut holes behind the dash assembly to reduce weight and make access easier, while i was in lightning mode i also performed the same process on the seat bases.
