Indeed, S4 Turbo
There is no special synchronisation feature, everything is machined accurately enough that all rotors recieve pretty much the same amount of air at idle.
No, I am not worried about that. The engine will suck at partial throttle response, but it won't be because of the slide throttle being close to the intake port 
How will you synchronize the rotors with that slide throttle? For example, if the clearance between the plate and the housing increases from rotor 1 to rotor 4 due to tolerances; rotor 1 may barely want to idle and rotor 4 may be wanting to take off. I suppose good tolerances would solve that problem though.

First time on this forum in a few years. Wanted to subscribe to this thread.
Beautiful work!
I'm up in the Stockholm area working for Scania and was thinking of making a trek to Netherlands at some point. Care to do a show and tell for a stray American sometime in the future?
Cheers,
Zach

Sorry, haven't done a whole lot on the 4-rotor in the last few weeks. I did do some work on the slide throttlebody, it's got a sliding TPS sensor and connector now, but nothing huge.
It might be a bit off-topic but I've been doing some work on my broken down bmw that threw a few rods a while ago because driving the FD around every day sucks! Unfortunately working on the BMW is taking a little bit longer than I thought
, some FC parts found their way into the e30 engine bay and it took some effort to make the FC parts work with the e30 engine
The car does run at the moment, but it runs like crap. I've got it running on liquid propane, and it's a very old system with a vaporiser and a mixer. Combined with the turbo it doesn't work very well. I've had it dialed so that it would run under full load, and it feels pretty fast at 0,7 bars of boost
but I've just about had it with the propane so I'm ditching that and fitting some fuel injectors, a pump, regulator and a very simple ems. Got some dual tower coilpacks and a spare FD coil igniter so I might ditch the distributor aswell.

Wasted spark plug
I'd say, finish the 4-rotor...
What can be more interesting than a home made, low cost but cleverly designed rotor beast?
Huh?

Ok sorry, we're just waiting...that's hard!
Hope you're on-topic soon John! ��

Your right though, the 4-rotor will be awesome! But after 1,5 years of spending every spare hour on this thing it was kindoff nice to take a step back and just mess with something else for a while. The e30 is perfect for this, because nothing needs to be nice or pretty, and everything can be ghetto but it doesn't matter because the car doesn't care one bit.
But anyway, I did pick up work on the FC
. First I messed some more with the slide throttle body because it still wasn't working perfect, the aluminium sliding plate with the bearings worked fine, but when everything was assembled there still was some binding here and there. It's all working fine now, also added an idle adjustment screw.The exhaust also needed some work, because there weren't any o2 sensor bungs in there. I added 5 of them, one just after the collector which is going to be used all the time, and one for each rotor, which allows me to mount a second o2 sensor and check for AFR differences between rotors.
Also mounted the waterpump and injectors
Injectors and rail mounted
4x ID1000 injectors supply fuel. Also note the viton o-rings on the intake tubes, they seal up the intake
The engine at the end of the evening
