Top gear - Cadillac W16
Saw top gear on sunday and they were reviewing the new cadillac mental machine.
It sported a 16 cylinder engine in a w formation (a bit lie 2 v8's side by side)
and put out 1000BHp ...
So anyway it's got me thinking...
Has anyone else come up with any bizzare engine combinations or alterations?
How about a couple of flat fours on top of each other ....
Maybe i need a little lie down..

i suppose an X configuration would be someting different, if it's ever been done! either 1x v8 & 1x upside down v8 or 2x flat fours mated
across the middle!
would have to be injection mind you, wouldn't want fuel dripping everywhere out of carbs!

Hmmm.... radial aircraft engines spring to mind.

Or the engine fitted to the Deltic locomotives...
Several banks of 3 cylinders, mounted in a triangle. Each of the 3 cylinders has a pair of pistons in opposition (i.e. on the compression stroke the
pistons move towards each other).
Although it was a diesel, it sounded like a turbine - weird!
Now one of those in petrol would be interesting...

thinking some more on the subject...
some tank engines have horizontally opposed pistons in a single cylinder... maybe 2 xflow engines, 1 upside down on top of the other....
I really need a lie down now....
Or better still, how about a few 2 stroke engines from performance bikes strung together - imagine the acceleration... 
Help - the men in white coats have come for me.....

IIRC in the 60's BRM produced a H16 engine. But it wasn't very succesfull!

Some of these ideas sound similar to the VW W8, 12 and 16 engines they are now producing - the W12 is effectively two V6's joined together.
There is an interesting article in one of the kit car mags his month about a V8 2ltr engine made from 2 4 cyl bike engines - producing 300bhp. Sounds
good but htey are £14 +VAT. Not quite locost.

Too succesfull really, it produced to much power and broke things,then the regs were changed so it couldn't be used.

Pretty sure it's Which Kit? I saw it in.
I've actually seen the real thing running at Stoneleigh.
Here's a couple of pictures:
http://www.locostbuilders.co.uk/~ned/shows/stoneleigh/index.htm
Strangely enough it sounds just like to YZF 1000s standing next to one another!
I'd be interested to know if there's much benefit in spending £15K on one of these and getting 300BHP as opposed to £8K on a 450BHP
Hyabusa engine?
Cheers,
James

Forgot the K - the price is £14000 + VAT!!
I am sure it is Which Kit - the one who are currently building an MK Indy.
The articel says it sounds like two bike engines rather than a V8 (shame that) but that it is very driveable, where a 450bhp (or even 300bhp) tuned
bike engine may not be.

BTW, that cadi is a V16, not a W16. You're thinking of the VW Phaeton and the Bentley GT, which both have W16 engines. IIRC there is a Passat
with a W12 engine.
Kingr
BTW, I didn't realise just how enormous the cadi was until I read that it's 2 feet longer than a 7 series BMW!!!

See
http://www.brooklands.org.uk/reunion/nr10.htm
for Napier Railton W12 - 24 litre
David,
I saw a scale model of a Deltic engine at the Model Engineering Exhibition about 10 years ago - they're a great idea, but I think a little too
much space is required.
And they probably weigh about 3 tons each
Nice schematic for those that don't know of them:

Good links Simon!
I read the article about making the scale Deltic engine - 3 banks of 3 cylinders, 18 pistons, 52 rings!
Mind you, there was another scale engine made by TD Walkinshaw Engineering (Tubal Cain, if you read Model Engineer). It was a one-sixth scale RR
Merlin engine - which actually ran...
cheers,
DJ

I stand corrected. it was the VW with the 'W'
But the caddy still had 1000bhp!
hmmm 1000bhp in a locost - that would be about 1500bhp per ton... hmmm
I need another lie down

David,
Used to read ME about 7 years ago(?). Not since:-( Though may be buying a lathe later this year:-) so may start again.
There's a chap (who's names escaped me) from a local Engineering Society who's built (from scratch!!!!) a flat 4, replica 1/2(IIRC)
scale AJS7R motor - complete with remote twistgrip (scaled!!), a 3 cylinder radial (barrels remain stationary) and a 9 cylinder rotary (whole engine
rotates - not wankel) - this, as you may imagine, is quite a site to see. If I can find some pics I'll put them up!!
Talking of large engines - if anyone's interested (I am, but no use for it yet!!) there's a 455cu in (7.5l) Buick engine and auto box on
ebay for £250 at the moment.

I've only scared one neighbour when i started the 350 in the garage on its frame with manifolds only one sunday
the other one came to see what it was and was stood there egging me on to give it some more stick but was suprized when on the over run the flames
that come out of the manifolds.

Reminds me of a video my mate showed me - a RR Gryphon engine on a stand, with a 56-gall water tank for cooling.
His video camera was on a tripod - nice steady shot until the engine started, then the whole thing started vibrating, about 30 yards from the
engine!
The owner stopped the engine when the water tank started to feel warm, measured by putting his hand on it.
The same bloke owns a tank or two, plus assorted engines including a hand-started gas turbine used to start jet fighters.

As the site says, it's a myth.
Have a look at this - much longer winded, but just as amusing.
