Allen Millyard's giant boardtracker, the Flying Millyard, built to house the engine he had created using two cylinders from a Pratt and Whitney 1340 radial. The result is a 5000cc V-Twin and it's a beauty to behold.

To begin, the bike, at idle, has the pleasant sound of an old radial biplane idling on the taxiway, if you've ever heard an old Waco or Stearman, you know what I mean, and on the road it seems to cruise without effort, as a 5 liter V-Twin certainly should. The Flying Millyard, though, does show one shortcoming of building engines this big, and that is, trying to get the proportions of the bike right when it's going to be ridden by a normal human being. The engine can't be squeezed into a normal frame of any sort, so you end up getting an outsized lump in the center with very long handlebars for the rider out back.

There's some nice build pictures of that V-twin engine on the Warbird Information Exchange forum. His engineering skill is quite something, building all the crankcase and crank itself.

found a link for a merlin engine on a bike also!
Little bit of an update.
I have decided to go with 12 throttle bodies.
These
They will need some adaption to get them to fit
When the soda granules I have ordered arrive I will clean them up so they look sparkly...
Two 39" x 4" x 2" billets of aluminium are next on the purchase list and then the fun begins making the inlet manifolds.

Why the change?
What's wrong with what is already on the engine?
A change to fuel injection because the engine is on SU carbs, IIRC.What's wrong with what is already on the engine?
Steve said:
Surely they won't give anything like the fuel flow required of such a vast engine?
If my memory is working correctly, and the engine is on SU carbs, the then M3 bodies will flow massively more air than the carbs.Storer said:
Oh dear. I hoped nobody would ask....

You should have said that they were from the modern arm of a company called Rapp, who produced aero engines 100 years ago. 
I like the idea of using ITBs, but I wonder if controlling them may give you more headaches than using them solves.
Good luck.
Hopefully a few answers to the above questions/comments.
The original twin Zenith carbs like to 'slosh' great dollops of fuel into the engine. They are mated to a water cooled manifold and the whole arrangement makes accessing the 'between V' spark plugs (it has 24 spark plugs) a bugger. This carb/manifold arrangement also weighs about 75lbs!!!
It makes the engine running and starting more 'hit and miss' too.
I could have gone for three 102mm throttle bodies mounted to a common inlet manifold but that would still cause access issues.
The BMW M3 E46 bodies are 50mm individual units on a common shaft. With a new shaft of stainless steel they can be spaced as needed. I will have to fabricate a fuel rail to suit, but will probably not need the balance pipe as there will be air movement in the head between cylinders as this will not be completely sealed.
The control of the throttles is mechanical and the banks can be linked to a single throttle cable. They already have a position sensor that can feed the ECU. It is likely that the existing injectors will be large enough but time will tell. They are plentiful and well known in the tuning market.
With electronic control of the spark and injection the engine will be much more tractable and fuel consumption improved. I want to use this car a lot when it is complete so would like to get the best MPG I can but still have the 'fun' of a vast engine.
A purist would say 'leave it as it is' but then the same could be said about the whole car. Besides, if it doesn't work I have another complete engine I could fit instead!

Flames from the exhaust may have to be fake though!!!
