    There plenty of flow area so flowing enough air flow is no issue. The volume is about tuned frequency and that will have to be what is unless I want to alter the deck lid.

    Mark - All the detail work has looked great all along this thread and now the final product is starting to crystallize and look fabulous. Pretty cool how much your little guy has grown and can help you out - there are all sorts of great lessons you are already passing on to him by setting a fine example.

    A thought on the cylinder heads now that you are at the point of fabricating the airbox. Will the fit be tight enough that the thickness of a compressed head gasket (X2) would upset the spacing? It would only be .010" or so each gasket, but you did mention things were really tight. Just a thought.

    Yes the gaskets will matter, they are .055 compressed and that will change things a bit.

    What about when the heads need skimming, etc. maybe in the future?

    How ever you design this airbox you need to take that all into account.

    Since you will be modifing the rear hatch anyway, you could have the plentum attached to the rear hatch so that when you open it up, it would lift off the TB's to expose the engine for viewing? My guess is you will doing a lot of "viewing" and taking the plentum off and on will be a pain. All that would be needed is a custom compression type gasket to seal when the plentum is lowered to the TB's. Not sure if you thought of that much work but at this point....:)

    Cool idea - I wouldn't have thought to make the cut diagonally. :)

    All the best,

    I really do understand good filtration, and the work youve done/doing is beyond ambitious and certainly worthy of good preservation. However, that motor is not only one of a kind, its montrously pretty. If it were me, and I know its not, I would risk a somewhat shorter engine life/faster cylinder wear and put some decent foam filters on those throttle bodies rather than hide its beauty and your amazing workmanship under that huge plenum. Its not like its going to be a daily driver taking excursions down occasional dirt roads. Or is that what your planning? And the sound that monster would make with those throats allowed to breath should be equally monstrous.

    Perhaps Mark would allow a poll vote to decide? Marks V-12 conversion: Plenum, or bella machina?

    It really looks incredible. Any gear head worth his dirty fingernails should be drooling. Makes a guy wanna go bankrupt buying machine equipment and welders.

    I love the look of open TBs too……but covering them is really the best answer. Think of it as lingerie for the engine ;)

    if it was me I would build a clean laboratory environment to run it in and filter the incoming air twice to avoid having to re-do anything :D

    whatever Mark decides to do, once the car is parked at a show he could remove the airbox to show off those throttle-bodies.

    Yes. The plan is to build the cover of the air box to just pop off/on.

    What I'm doing will look at least as good and will work much better. You guys have to remember you're looking at pictures I took at an angle that shows the air box idea well but from the side you get a completely unobstruct view of the TBs .

    Mark,

    Make a mold of the air box top when finished and have one cast in lexan.

    Good filters are the best idea.

    Tom...

    Looks great Mark and still shows off some T&A (throttles and airbox...).

    I think the stock ribs, Ferrari and QV badges and perhaps a pony will give the exact "could it be stock?" look you're going for.

    You are an artist... Cheers

    Saturday endup hot rod day in my shop when a couple friends stopped by with projects but I did get to spend a couple hours welding and grinding the air box. I'm thinking I'll put the air inlets on the ends,,,but if I want the top to pop off easily I guess they should be on the bottom part no the top part......which will make the seal a little harder to do. I'll need to think about it a bit I guess.

    I'm thinking I am going to have to agree with everyone else who's STRONGLY suggesting the lexan top on the plenum. I know you want this thing to look stock and like Enzo himself built this as a mad scientist edition and everything, but that would just be amazing. Maybe as an optional plenum? You've surely got enough aluminum laying around there to make 2 of them. LOL

    Laters,

    Brian
