I'm not unfamiliar with a standalone system so that may be my first route. There's some place here in Utah, Turbolab, iirc, down in Provo that tunes boosted cars no matter the type, and there's another that does Vw's specifically. When I get to that point I may end up seeing what they think. I'll try and go down there sometime next week. I've been looking at the intake setup, I might end up having to find an Eaton m112 from a mustang or something, the M90 may end up a bit too small.

I had looked at this before and now I can't remember, but I think the Eaton M112 from a Jaguar is the one to use. Again, memory is my issue right now, but if I'm correct those M112's had a similar set-up as the 2.8 V6 Passat kit. Basically, you want to have the inlet at the back of the s/c and then the bottom of the s/c is where it dumps into the intake manifold. That would keep most everything in it's original position.
You can pick these things up for like $500. Strip them down, rebuild them and have the rotors re-coated for around $1500 all in. Nice cheap horsepower.

So, I'm making my best attempt at dropping the engine, trans, and subframe. The wiring is my concern. Would it be best to remove it from the ECU and drop it out as a unit? The alternator and starter wiring is also a concern, as it doesn't fit well away from the body.
Also was working on the supercharger, got some plans, and an idea of what my next steps are. There is no way to make this a kit after the research, unless Eaton wants to custom cast some parts.... Doubtful.

Got the title body area cut down, sending it to a machinist to mill it flat.

And began porting the outlet. This has been a crazy project so far. I also have been making some rough drafts of an intercooler to mount below, which means I really need to cut the hood now. So, a custom hood is now in order.

Well, I have yet to pull a W8 engine but if it's anything like the V6 or 1.8, Disconnect the harness at the ECU and some other minor connections, grounding wires in various spots, obviously any hoses.
Disconnect the axle shafts at the transaxle, remove the rear prop shaft, remove the trans mounts, unbolt engine mounts, unbolt the struts on top of the strut towers and yank the whole thing out as one. I may have left a few minor pieces out but you get the gist.
That's how I've done every V6 pull. I've pulled about 20 V6's since 2011. It got to the point where members here in the forum were making fun of me. I got real good at it the last 3 or 4 times.
Every one of these pulls I've done by myself with no extra help. Very doable.

I might be willing to offer my CAD services for an adapter plate from the s/c to manifold. I don't think it would be that difficult.
Mind you, I've contemplated this exact type of project for a number of years. I've since given up on it because I have an even more crazy idea that I'm pretty sure has never been done.
My only issue at the moment, I'm going to be traveling a lot until after the 1st of the year.

Well that might be a good thing to get help building. I decided to just drop the entire subframe. It was easier to just pull the entire wiring harness. Last thing I gotta drop is the rear drive line and the socket broke. So I'm gonna wait till tomorrow now.

What happened to the back of the s/c housing? Did a chop saw fall on it or what?

W8 intake - top side
101583






Adapter plate - mounts to top of W8 intake.
Then obviously some kind of transition to mate up with the bottom side of the s/c.

A student used a bandsaw to hack it off. Another at the machinist school is going to mill it flat. The plate I'm thinking of will have the intercooler inside, and go from the lower intake up to the bottom of the charger.

Well, had some good things go through this week. Got the blower housing machined flat, and found a suitable spacer to be used for the throttle body. I dropped off the nose cone and shaft to get shortened, should be done by end of next week. Andreas would it be better to mock up a piece here for the intake, and send it to you, or should I just try something here and we can work it out later?

If dimensions could be obtained from the mating parts that would be best. But if that's not possible, taking a picture of the mating parts could work too.
Would need a straight down shot of the part (meaning, having the camera directly above the part, centered and parallel).
You need a picture that is true to it's form without having any skew to it.

More news, I have the snout finished, just need to pick up up today. Also began making an intake manifold blank, that way I know what it will take to make a new metal piece. Currently it's wooden at the moment. Also got the throttle body mock up progress a bit further. Figured out what size adapter, and it's positioning.

This is before I get it welded up. Throttle body is on with it.
101722

This is my beginning of the manifold. Going to make one out of wood to build a blank then be able to cast a new piece. That way it can either get a billet one or a cast unit. This is just so I can get it organized.

And I just picked up the snout from the shop and damn I'm thrilled. It looks great, and sounds perfectly balanced.
101731

Shortened just enough we hope. Now I can make my measurements to get this baby aligned and setup.

That'd be way easier to make out of 6061 aluminum bar stock and cheaper.

Have some questions if anyone knows.
What size injectors are in the W8?
Like how many cc's or lbs rate are they. I need to find some more higher flowing ones to have installed for boost. I was debating the turbo V8 Audi ones if possible.
Why does nobody do a tune for the manual trans? Can VCDS tune the ECU or what program should I try to use? I've tuned others before using a stand-alone, but not sure how these variable cam ideas will work as such.
I'm sure there's more, I'll figure out later.

I don't know much but I know VCDS can't tune the ECU. There might be some aftermarket tools that can read/write the EPROM (eg Xtool 401) but they will have zero documentation on what the various bytes do so I wouldn't suggest going that route.

I had this info somewhere, be damned if I can find it now.

There might be some info here.
I read a little bit of this, but the back and forth bitching got to be a little much.

Bigger injectors on stock tune?
