Hunton/ilmor Build

[larby]

Quick (and possibly stupid question for you).
In the last photo you put up of the stbd engine being trial fitted, it seems to overhang the central engine bearer? How does the port motor therefore fit in alongside it??

I'm sure this is a stupid question and I'm sorry if it is, it's been a long day!

Amazing build by the way, lovely to see such care being put into building a boat with nothing but the best parts.

All the best,

James

They're being staggered I believe...

Peter you appear to have a marina in your garden, stop making me jealous!!!

Muppet. I'm a complete bloomin muppet. I'm going to bed now before i embarrass myself further!

I'm also very jealous of the marina garden, and the boats, and the quad, and the holden.....

Hi James,
PAUL E is correct the engines are staggered at 20'' centres the starboard one has a plug in transmission & the port engine a drive line transmission & is connected to the transom shield with a carbon fibre drive shaft. Will post pictures soon of a mock up to give you a better idea.
Have been watching the Revenger build with interest & i think you have made the right decision to stick with it what about sticking a blown alloy small block in it? as it would give the hull a much easier life as it is so much lighter but still has plenty of power.

All the best
Peter

P.S.: Port Hamble is a wonderful place to live, wouldn't swap it for anywhere

out of interest peter, who did the seats?

Hi Tom,
John from Hunton has trimmed the seats, i modified the mouldings myself with parts supplied by Hunton.

When do you feel it will be ready for water testing?

Hi Boatless-Again,
The original launch date was to have been 3rd March as the old Cheetah was launched on this day 3years ago but the Ilmors were about 8 weeks late in arriving so although i can claw back some of the time i want the build process to be an enjoyable experience & i don't want to cut any corners, so i think a realistic date would be late April.

Finished off the engine bay modifications today.Dropped the centre engine bearer by 115mm for better access to engines also cut 18 4'' diameter holes carefully spaced between engine mountings to allow easy access to some of the mounting bolts & also allow free air circulation so that in the event of a fuel spill or leak the bilge fans will be able to evacuate the fumes more easily.

Hi All,
Had a trial fit of the partially trimmed bolsters on Thursday so that we can sort out the padding required on the headrest & bases.Will drop in the engines during next week for a trial fit to enable fabrication of exhausts and engine mountings, we will also measure up for wiring harnesses.

I'm not one of those into health and safety but i think a crash helmet might of helped especially if kids watch

[Mike_G]

but he had a crash helmet, the woolen one:-)
Good in off-road biking and atv

I've checked that, really works

Hi All,
Been quite busy over the last week or so designing engine mounting supports.Awaiting quotation from carbon fibre manufacturer, also been designing steering control system which has taken quite a lot of time & effort finding appropriate components. As you probably guessed the hydraulics side of it is no problem to us at all but the electronics to control the hydraulics has proved to be the headache,but i think we are now sorted so here is a brief outline of how it will work.
Each engine is fitted with a power steering pump which will feed oil into a fully proportional directional control valve the outputs of which are connected to the steering cylinders.The electronics side will have a rotary twin track transducer mounted in the steering column & two of the hydraulic cylinders will have linear transducers both feeding information to a programmable ECU, as this is a fly by wire system we will use dual components interacting with each other to make it as safe as possible.As all parameters are programmable we will be able to change the steering ratio giving plenty of feel in the central position gradually ramping up to give better low speed maneuverability & docking manners.Also we will build in self centering so it will be much more car like to drive.I am also looking at the possibility of tabs, trims & throttles all being steering wheel mounted, so we will be constructing a bench test rig in the near future.

I take it that your not concerned about this boat conforming to CE regulations then?

[Numb Nuts]

I take it that if there was an electrical faliure as in the batteries failing this would not affect the steering response. Just the thought of hammering along at high speeds then the steering going all burty would certainly get your attention.

going all.........??
and why would i get there attention????

Bah, stuff all that H&S Bollox, it's crushing us all. I think it looks like great fun. Well riden/driven. do you have two wheels as well, or just the 4?

Put a number on it and he'll be fine!

Actually this is one of the main reasons I hate the CE system, many Ribs are assembled from a kit of parts at a dealers "workshop" which may or may not have the required skill levels and equipment to do a proper job of assembling said kit.

Assuming all of this was CE'd at the factory where the boat was originally assembled how officially would the boat stand?

And then the customer may fit or remove all sorts of bits and pieces which would change everything, especially if the motor was "upgraded" to beyond the original intended horsepower?

Electro hydraulic does scare the bejeeburs out of me in a high performance boat, but if anyone can pull this off I suspect Peter can!

[Jim Brooker]

I installed a complete electric steering control system back in 1973 to HTS 2, it was designed by Mike Bellamy, after we swapped ends a few times I stripped it all out and fitted cables.
I know it was a long time ago.!!!!!
