now call me thick if you want...
but if you are putting the engine and box behind the driver and it was originally intended in front(audi,ford,vx fwd cars) what does the gear linkage
look like and how does it work, any pics or sites would be apprieciated..the rest I can grasp but this...well...
cheers

Alfa
I am using an alfa romeo gearbox!!!
Same deal as with audi but the engine is a boxer layout. Used originally on alfsud but go for alfa 33 o I think some early 75s.

Audi still builds longitudinal on all models exept A2 and A3, these are volkswagen-based and therefore transverse.

I spent a bit of time looking into this and before i elected to build a v8...Lotus 7 i thought about a v8 midi. The same problem came up time and time
again. The only affordable box that could handle the power of a tuned rover v8 was the Renault UN1 box as used in the renault 21 etc. A very rare unit
unfortunatly and prone to distructing itself. Afrter that its the porch box and a porch price tag. Iwould be very intereting to know how much power
these audi boxes can take, but seeing as though its difficult putting more than 200bhp on to the road with a front wheel drive car you may encounter
similar self distruct probs with these boxes.

What a beautiful drivetrain. I've often thought if I ever did a large engine midi, this would be the choice. Rumor is the BMW V12 (from the
800-series car) engine can be obtained very cheaply (<$1000) because no one wants them... With an aftermarket ECU it should make getting the
engine running relatively easy.
What does the above setup weigh? What does the Audi gearbox cost?
Is there a transverse transaxle capable of handling a V12?
Must make wonderful sounds... and that's important!

Its got that merlin look
or should i say ME109 look!
Beautiful
PS
I can see you have elected for rigid suspension, which is entirley wise with such a monster strapped to it, but where is the seat going?

not my engine BTW, just snagged the pic from another site, but can't say I haven't thought of it.
I'm told that the audi box handles this power and more, there are labmo kits with V8's sourced from vettes using these boxes reliably,
I'm planning on using the audi box with a vw 2.0l 16v engine, I may just make sure there is enough romm in the engine bay to fit a v12 later

Well, you could use the Porsce gearbox as it can handle around 800HP as illustrated by Ultima fans using it with VERY fast small block
chevy's.
Those v12's are very cheap. I have heard rumors of them going for 500$ here. I am going to test the rumor and see if I can get one for a
streetrod. I will probably convert it to carbs for simplicity sake.
as for weight.... 26 inches long and weighs about 500 lbs. with accessories.

Transverse? I'd imagine that some of the big American FWD's now have transverse supercharged V6's and V8's etc I would have
thought that the big problem with a transverse V12 would be the length but if, as Matt says, the BMW is only 26" then that's probably
manageable.
Are you planning a Miura replica Kurt  ? That's the only transverse V12 I can think of. There's also the Cizeta V16 but that
'cheats' by taking the drive from the centre of the crank. The MacLaren F1 gearbox is transverse but with longitudinal engine. Not
common at the wrecking yards though

Here I go "jacking the thread." I own the McLaren F1 book, a fabulous book... and I *never* use the word fabulous. Anyway, I
couldn't find where McLaren explains why they placed the engine north-south. Does anyone know? They kept talking about how important it was to
cram everything between the wheelbase, okay fair enough, but it seems like they could have saved lots of front-to-rear space by placing that same V12
transverse.
About me building a V12? Just dreaming for now.. and yes, I also heard of $500 BMW V12s. Seems a fantastic price for a nice piece of engineering,
perhaps it's even price competitive with the proverbial Chevy v8, but only if the owner does all the work to it... As you said, having one of
these in just about anything would certainly be different from the usual.
Heck I'm all over the place... A V12 would sound wonderful... but so would a BEC with it's "free" sequential gearbox (which
for a car costs a fortune,) or an electric 3-wheel commuter vehicle... No, I need to finish the Mini and rest a few years... then we'll see.

Looks like the same kind of setup a guy is using in a Ultima. Audi gearboxes are pretty strong but a bit clunky. I had an Audi S4 with a twin turbo V6
that put out 415hp and about 495 ft/lbs of torque. I used it mainly on the track and didn't have any problems. If you're into drag racing,
the second gear syncros have a habit of failing.

If I had to guess, I'd say they probably mounted the engine longitudinally for aero and balance issues. Afterall, venturi undertrays can take up
a significant amount of room, and it probably balances better laterally, especially with only the driver aboard.

To minimize vibrational problems, the engine's should be mounted inline with a centre line through the car, north to south. That's why
Audi persist with it. My mate ran simulations on British Aerospace's mainframe for many a costly hour on Rovers behalf, proving just that.
Transverse engines tend to get pushed over into a corner where they vibrate away merrily. V's are not as smooth as straights (they introduce
unwanted lateral forces) but the current trend for V6's is so they fit in transverse engine FWD installations. Just as well there are
multi-zillion quid mainframes around that can be used to design clever engine mounts to mask much of the engineering problems.
Weight distribution in the east-west plane is easier to manage too. The engine-plonked-in-corner-of-car scenario causes many a headache with weight
distribution issues.
For the McLaren to mount the engine transversley with a decent east-west weight distribution, it should be mounted centrally so the gearbox then goes
underneath. Oops! There goes your centre of gravity.
North to south, with an inline engine is the simplest way to avoid these problems. It's only the insistance of manufacturers that the human
animal is incapable of driving a dynamic vehicle (i.e. RWD), the easily placated-with-tinsel prolatariate (marketing speak: 'Surprise and
delight' ) and the insistance of the bean counters that everything be cheaper that pushed the transverse world onward. Oh yeah, it liberates
some interior space (y'know, the bit under the heater that everyone finds soooo useful.)
Cheers,
Neil.

transaxle info
Try...
GT40.com
Lambolounge
I scrolled through these sites a while ago and there is a lot of gearbox middy stuff on these sites. Try the Getrag website for details of where their
boxes are used and how much torque they can take.

Oops. Ah well. I would think that a Caddy gearbox off of a Northstar platform would be able to handle anything you could throw at it. (within
reason...)

This web site tells the story of the development of the F1 transxl.
http://www.weismann.net/supercar.html
There is a picture of Gordon Murray testing the layout. The setup looks positively low cost
Also look at this site:
http://www.just-the-one.net/index.html
under the FAQ section. It states that this car can be driven with one engine in 2nd gear while the other engine is in 6th!
Cheers

un1
Just to flog a dead horse...
If you run a un1, and you dont fancy reworking the entire car to suit a different unit (and your breaking them lots) :-
Derek bell does a performance rework of them.
http://www.bell-performance.co.uk/gearbox%20upgrade.htm
I plan to go something like this route (but perhaps not the full monty done in their works but leaves me poor version) if I break lots of boxes (ive
got 3 spare)..
Im just discovering the un1 bellhousing is bigger diameter than the espace bellhousing on my ex renault espace transaxle (5 speed, strengthened ,
larger diameter input shaft and cheap). And in fact wont fit over my rover v8 clutch / fit my adaptor kit.

just a thort but ther is a citron transaxle that was fited in earler esprits I am not sure what citren it was fited in.
also sarb 900 up till 1994 I think had a transaxle however the clutch is at the frount and the drive runs back under the engin maby giving problems
as for the BMW v12 engin ther is an ultima build sight out ther where the guy has put a lot of efort in to recreating an car with mac f1 figures
(aparently the ultima was the mac f1 dev car) he has done some work on the engin to gett more from it s aparently the f1's engin was develped
from the 800 block and bits

My understanding was
that the Esprit's all used the Renault UN1 transaxle. If there was a Citroen one used it would be from the V6 engined SM coupe (which is
probably the same as the Renault one inside the casing).

It may be a little brave to describe the Ultima as a development car for the F1 It's more
accurate to say that McLaren used two Ultima's as the basis for their test mules, Albert & George. It's also accurate to say that
there wasn't much Ultima left in them by the time they got them working. As well, McLaren were fairly unimpressed by the engineering of the
Ultima. In Doug Nye's book on the development of the F1 he quotes Gordon Murray as saying (this is paraphrased from memory) "Early in the
project Mansour Ojeh suggested we get a Ferrari TestaRossa and just cut it about as a mule. I couldn't bear the thought of cutting up such a
lovely car. In the end, however, it may have been easier." Enough said, perhaps
