bmw v12 project
After building a few seven (BEC) with a lightweight concept I'm starting a new project. Goal is a fun car with a good shape and a V12 engine on a
tight budget. So I started with buying a complete BMW 750 donor car. I will use an Audi 6 speed gearbox from a S8.
First thing is to get the rough dimensions so I can start with the bodywork.
I would prefer to buy a complete set of bodywork but there is not much next to Lambo and GT40's (any tips?)
I am very enthousiast about the (round) shape of the Zonda so this is my starting point. Next thing is to collect things like windows and lights.
I could use any hints about the front (and other) window what to use.......
I will start on the chassis after finishing the body which is for me the most complicated part of the car. I do have some experience in building
chassis so this should not be to hard.

Hi Erwe
I Have seen some of your previous work and will follows this project with interest. Seems you are not scared of work! Think there was a thread on here
somewhere a while ago re a suitable screen. Have you considered a GT40 screen?
Cheers

The Lambolounge has a write up on a guy who mated a BMW v12 and an audi gearbox ( IIRC ) which may be of use. Your project sounds great. Not long ago
there was a Chevron B16 (I think) shell on eBay which would have made a lovely special especially if you are after the retro style. Good luck.

Andygtt, ihad a look at your site some time ago, what body will you use?
I saw you had a post on Audi boxes, are these from the S8 series?

Maybe a good idea to take measurements on the engine (L x W x H + mounting points, etc) for future reference?

Why not a bodyshell of a old “East German” Trabant. They are from fibreglass and easy to modify. Trabant V12 sounds like fun to me!!!

I did a basic dimension drawing for Geoff on this site and I've been asked for it by someone else.... so I'll pop it in my profile and
post it up.

I'm making my own body from scratch and I have in fact made a start..... I was working on the driver scissor door at the weekend and they are
almost complete and are actually already on a makeshift hinge.
I have very specific needs for my car body shape wise, which is why depite there being plenty of mid engined bodies around I eventually decided to
make my own.
Personnely I have no experience of the Audi box, all I know is from friends that are using it, one is mated to an M70.
Personnely I'm not as keen on them entirelly down to the fact that to get reasonable drive shaft angles the engine is actually 8inches higher
than mine is with my Porsche unit.
Thats a compramise I wouldn't take... but then even a budget porsche costs 2-3 times as much to use compared to an average Audi install.

8 inches?! That's an amazing difference...

In my Audi 016 trans setup, with a ride height of 80 mm from the ground to the bottom of the sump/adaptor plate lower edge to the ground, the drive
shafts run upward at 10 degrees, which is apparently okay for the CV's

Fred, that picture is a good example especially if you compare it to mine on the previous page. In mine the table represents ride height of 140mm at
the adapter plate.
My drive shaft angle points down at ride height.... but under 2/3 compression they go horizontal.
However its only really an issue if you are running large BHP and need them to be optimum for reliability and losses.
Edited to add that the std sump in the BMW adds over 4 inches to my dry sump setup.

Minataur is nice, but what about side windows?
i dont suppose its possible with such a curvature. Same thing spoils the ultima, for me, a supercar should be fully functional and if your
going to have a roof, then the windows should wind up and down.
This is quite nice, although i'm not entirely convinced by the back end styling.
It also uses leccy windows from the corvette doner, which earns my vote.

I would like to know if that GTM windscreen is available from other suppliers. I've been contacting them a while ago and they told me I could
not order it from them.
The Minotaur has definitely some pagani lines in it. If you have a look at the other pictures on their website you will see it.
Their description:
DOT front windshield
Is there anyone who can help me on this?

I think the Minotaur is a little overdone.
The GTM is a very nice car, but to much USA style.
I will have a look at rear windscreens on production cars to see if there is one wich I can use for front windscreen.
Andy, that difference in ride height is because the Porsche trans is upside down?
Do you have pictures of your bodywork?

I suspect our ride height difference is purelly down to different appication/use.
I have set mine up to run 110mm front 150mm rear at the axle C/L's..... however for track use this will be able to be dropped a lot without
effecting roll centres.
My body is hardly started so not really representative of what it will look like when complete. Its going to be a convertible with storable hard top,
scissor doors, electric windows (hated this about my Ultima) and electric seats.... and yes I am going soft.

Cool project!
What are you going to do with the ECU?
How about the body of the Aeon 420?
An nice Z8 replica based on a Cobra replica chassis isn't an option?

8" is quite a lot especially for a gearbox!!
The Audi box has the input shaft around 4" higher than the output shafts and the Porsche has the input shaft around 4" lower than the
input shaft. A case of two 4's not sounding as much as one 8
Advantage of the Porsche is obviously that the CofG is lower with all the cornering and braking advantages but at a cost and availability issue.
There is a cheaper method. Turn a transverse box round by 180 degrees. Bingo the input shaft is below the output shafts the only bugger is you now
have 5 reverse gears and one forward gear.
Hmm - easy! Reverse the CWP. Worked on my Renault UN1 box dunno about the Audi though.
Beware though there is another disadvantage the GOG is now so low the sump scrapes along the deck so drysumping is now required - at least thats what
I have to do with my Rover.
Ah well a Lowcosters life is never easy - fun though!!

I got some information about the EMS 8860 Sequentieel motorsport and the Stinger
http://www.emsnorthamerica.com/
The prices are from Euro 800 til 1300
Very interesting option is that it is upgradable with turbo!
I am looking for a windscreen, the Mazda RX7 1994 seems good to me, I have to measure it to be sure.
