Here is a little taste of what I am up to now...
supercharger?
I'm not tellin'...yet
Must be a pulley driving the a new fuel lift pump to feed your engine's thirst for POWER!
Here are a few more pics...
Is it an under drive lightened pulley?

I just put one of those on my g/friends Miata Jackson racing mp45
More progress pics - trying to lose weight on this assembly, right now I am 2 lbs. heavier than stock, I am working on it though, every ounce counts!
Couple of more pics on progress...
I went to a machine shop and had a chat with the guys there (they also race alcohol funny cars) and they felt the pulley was as light as it could be and no further machining needed.
I had a local welder TIG weld it for me, $75.00, it was worth it. My hands are not as steady as I would like for TIG.
very cool!
Does anyone in Southern California have an extra long block I could borrow for mock up, does not have to be in running condition. I could trade some fabrication work for your troubles.
Here are some more pics of progress.

It is not a Garret, I don't want to spend the money on one. It is supposed to be a GT35 with a T3 inlet. The reason I bought it was because the waste gate and exhaust matched my old one. The place I bought it from had it custom made.

I understand GT is a Garret trademark - you use a cotton swab, ubiquitously known as a Q-tip no matter who made it; A facial tissue, Kleenex, etc.
As long as the dimensions remain the same then it should function the same. If it doesn't work as the numbers say it should then my bad. I didn't buy it under the guise it was a Garret or even a perfect clone of one. It simply fit the need I have without completely reengineering the current design.
If I had the money, I would buy a Garret, but budget doesn't allow. As far as waiting until I have the funds, not what I want to do. I don't see anything wrong with using a clone, if you don't want to use one, that is your option.
As far as I can see the clones are made just as well as the real thing, fit and finish is spot on. They are made with state of the art equipment, not in some hut.
This thread is for progress on the current project, no offense, but I never intended for input as to how to build it. There are is more than one way to skin a cat.

As far as fuel, Tomnik is going to handle that. I will be getting some 7.5 elements from him and have his bud install them for me. The M90 will handle boost until 10 psi, then the bypass for turbo will open and it will boost up to 20 psi.
Boost on S/C will be bypass valve - Boost on turbo via waste gate.
I just got back from Bakersfield - 250 mile round trip and picked up an engine from Delivery valve - very nice guy.
I would just route the turbo in to the supercharger and let it rip!!!! lol compound 50psi all the way
This is exciting as hell! However, I would have welded it for $50. haha

Very nice!
That water pump is a little bit overdriven isn't it? Even the updated smaller pulley is only 0.9:1.

I like it. Beautiful job so far!
Looks like the vacuum pump indeed is getting in the way. Are you going to remove it?

OK - that makes more sense than terra cotta.
What is the trade name for that stuff (so that I may Google up some info on it...)?

looking good take some video of it runing

I have been making some progress, but a few revisions as I go along.
After measuring, it turns out the power steering pump is too big. I decided to use one with a remote reservoir from a Ford Taurus. It has a 6-rib pulley, but I found a brand new 8-rib and slightly larger for $18.00 - brand new (Ford trucks, vans and Navigators use an 8-rib).
I have been working on the power steering pump bracket and belt configuration this past week. My goal is to have at least a 33% belt wrap on the pulleys. I have looked at a few in the wrecking yards and some only seem to have 20-25% on the power steering - I think I will be fine. I am still fine tuning the placement of the tensioner and idler pulleys.
I use a cardboard for a rough template and once I have the hole locations I use a CAD system to draw the brackets and tweak for form and function. I can cut them out myself with the plasma cutter, but I am getting a price for a local steel supply to cut them for me. All I have to do is give them a .dxf file.
The next step is to work on the supports for the tail end of the SC, once I have this complete I will work on the SC plumbing...

I count 4 (maybe 5) tensioners... wow
that belt must be 30 ft long.
looks really cool though!
keep it up !

^^^ Nice, I'd love a BMW S52 w/ an EuroSport Twin Screw. That setup just has one additional idler and the TS pulley of course.
(12-30-2009, 10:37 PM)Rudolf_Diesel I am still trying to find out the trade name, but if you search for machinable resin or plug assist material on google you can get in the ball park.

superchargers all the way I love the sound of a twin screw I'v got an Eaton mp45 with by pass valve on my 94 miata
So something like this minus the DrosselKlappe (I assume throttle body)
stolen from vw vortex
Or maybe not a compound setup even though it has a bypass I don't know what the benefits would be. I assume the compound at the low end would kick in the turbo ealier as well as providing some good low end boost while not delievering overheated air at higher pressures.
It can work either way; super-turbo, turbo-super.
Though with the supercharger first, it can actually be a restriction as the turbo spools up. They only pump a fixed volume of air per rotation and as the turbo increases air consumption the turbo can pull a vacuum if the bypass opening timing isn't right. Open too soon and the turbo takes longer to light up, too late and the engine chokes.
With the supercharger after the turbo, bypass timing isn't as critical. It will just work as a really inefficient compound system (depending on the supercharger's set pressure ratio). Open too soon and the same as above, too late and you get a lot of hot boost.
Either way, its a hell of a lot better than either one alone.

No. The supercharger will be driven backwards by the air pressure.
I saw the VW system, but I don't know if it is feasable to run a clutch on this S/C. It is a work in progress and may change as it progresses. It may never be a drag car, although I would like a set of gears to pull off the line though, but it will be cool as hell. I can't wait to lift the hood when I go to another Benz get together. The purists just shook their heads that last time when I had the A/W IC.
I am basically going to copy the green wagen. It will have a 80mm (guessing) throttle body that will open and essentially bypass the supercharger and have the turbo feed the engine directly.
I wanted to use the OEM bypass on the S/C to open at a set pressure, but due to a clearance issue I will incorporate (Forced, look away) a bypass valve / BOV that will open and dump the output from S/C to input of S/C.
I have pretty much dialed in the bracketry and waiting on a quote from the metal supplier to plasma cut the brackets. I can do it myself, but it is just easier to farm this portion out. By the time I buy the material and cut and grind it will be done for a few bucks more and ready to weld.
I guess I should finish my DIY torchmate kit that I reverse engineered

Just try to avoid its convoluted tube layout.
There are so many points the wagon's system could have been simplified/improved....
