I agree with the crossram

The crossram looks awesome, but I imagine that it would be much, much easier to set up an air intake/filter system on the vertical pipes.

it would be equally easy. K&N makes bolt on filters for IDA style TBs or carbs, bolts right to the face where the velocity stacks bolt down
crossram is looking awesome! WOW!!!

I was thinking more of the classic Ferrari style, with a big oval air cleaner. Those K&Ns would certainly do the job.

Thanks guys-
Sam- I personally don't think 'EASY' is in my vocabulary...
The guys across the pond are light years ahead of us in ITB's - a LOT more universal ideas- the ones made in the states are mostly one off w/ not much thought to being able to adapt to several different applications....
I decided on the Crossram look- I machined down the aluminum pipes I cut off from the stock OEM manifold- then tack welded the flanges to them for a test fit. Just a little bit of clearance needed - but it's gonna work. Stock fuel injectors and fuel rail fit - but a little on the tall side.
W/ a level and a tape measure it SHOULD fit...if not I'm going to look into shorter fuel injectors- stock ones are 75mm and I've seem several other there that are 25mm.
Hopefully one night this week I'll pull the old mock up V12 intakes test fit my new ITBs.

Nice! Which bore do they have? 48?

Here's Three Webers in a K&N. Surely thy'll have something for you?

Thanks guys-
They are 'only' 40mm TB's - but that's times 12!!! 48's would be way to big....40's the same size Jags run w/ their V12 and Jags about the same size as far as displacement.
Steve- you're right- there are tons of options for filters /velocity stack AKA air horns- that's why I went w/ these throttle bodies- very universal- and even the linkage interconnects- so the throttle cable will be as simple as hooking up 2 4bbls.
I was able to do a test fit tonight- and it looks like I won't have any clearance issues-here's the mock up engine in the car -
Look how easy the plugs are to get too....
In the mean time I went out and bought another V12- I got a great deal on this 750IL...I know...I know..I admit I have a problem...

admitting is the first step - but as far as problems go, you having another a V12 BMW really makes me feel sorry for you :suspicious:.... NOT :lol:

Here's some updates.....My goal is Hot Rod Power Tour this June!!!
"THE" engine is sitting between the frame rails- after pulling out the mock up
Everything fits -albeit a little close...
Hood fits- even w/ the fuel rails...
Have the electronics figured out- running the just released Megasquirt MS3 pro- will run sequential fuel injection for all 12 cylinders...and using LS2 coil on plug
Here's the wiring harness- parted out a BMW harness and reused the connectors and wire tray-
This was kicking my ass...but I worked out w/ a couple visits to the junkyard and hardware store...Mercedes and Audi parts...
Here it is actually working...

Damn, that is just so beautiful. What;'s that bell crank from? I could use something like that!
Richard454
Well-known member
THANKS!!!!
The bracket is from a late 80's Audi 5000 Turbo- cut down and welded up to some 3/8 aluminum...and bottom bellcrankpiece is off the Audio -the top part is off a 80's M-B 420SEL...
I used M5 X .8 threaded rod covered w/ 1/4" x .028 stainless tube and either the M-B or Audi ends. I like the Audi's better because it has a neat wire lock system- but only one Audi was at the junkyard...
For the main shafts- I used 5/16 stainless steel rod and four Aluminum Throttle Linkage Arm 5/16" from Speedway Motors.
And the brackets on the ITB's? Thet are actually exterior (Home Depot)door hinges- stainless steel cut up.

wow thats a cool project....as was said before not enough O's to go in cooooooooool....

So it looks like you have 12 individual throttle blades there, how in hell can any mechanical mechanism control them precisely enough to have equal air volume?? just a smudge off on an adjustment due to slight wear or crap build up, and it's over.....seems like a maintenance nitemare.....especially at idle.....
my LT1 setup, I had to clean the throttle bores just the other day, engine idle in/out gear being a automatic...acted real erratic... I can't help but imagine that cleaning 12 blades/passages would be any easier....
curious to hear what everyone says about this....

Gene-
As far as the mechanical set up- the bodies are set up as twins- pretty precision pieces- a couple of set screws on each side of the center TB to adjust and then the electronics take over ...An air idle control valve is controlled by the ECU to set idle - I have made a vacuum distribution block or rather tube connected to each throttle body-and took some threaded rod- drilled out the center to attach to the throttle bodies idle air bypass circuit.
Here's the vacuum dist tube I made- fits between the linkage.
Here it is between the throttle bodies- I am making some new lines out of hard plastic for better clearance.

I just didn't like the fit NOR the look of the lines for the vacuum set up.....
So here's what I went with-
I cut down some injectors I had sitting around...tapped them for the hollowed out threaded rod I made to fit the throttle bodies...Now I have a nice looking way to route the vacuum. Plus the fuel/vacuum rails polished up nicely.
I'm going w/ brakeline tubing to connect the 4 fuel/vacuum rails -to the MAP sensor...
Now I just have to drill 12 more holes in the fuel rail...

It's ALIVE!!!!
An Update-
It's actually running now!!!
Working on the wiring now- but hope to have it on the road in a month-
Suspension-
Vansteel coil overs all around and Wilwood 14" rotors up front-
Stock size out back

Looks like your almost on the road, congrats!
I like the hide-away license. Will make a good getaway car.
