Great work, commiserations on having stuff stolen.
noticed a lot more whining from an Eaton once when there was a big hole in the boost pipe (you get a lot of noise downstream of them & if it's plumbed in direct you don't hear it) your bypass piping might let the soundwaves come back out the intake filter? Can't think why the belt's slipping so bad though - unless you're pumping a lot of air that then has nowhere to go.
IIRC Lancia Delta S4 setup ran the blower conventionally (no off-load/idle bypass) the blower bypass just opened gradually when turbo boost overtook blower boost. Diagram doesn't show any throttle plates but i think it was a single plate in front of the blower. That seemed to work alright for those crazy Group B rally boys That's exactly the way I have mine

Dies make sense Supercharger is m24 from golf tsi Turbo is tdo4 from a Saab I've just took it all off again, gunna re plumb it supercharger first Worth a go Pretty sure I suggested this layout back in January , I would have a good look at the rotors for damage as the vw system only allows the s/c clutch to engage below a certain rpm level

One of the outputs could be set to only engage the sc below say 3000rpm with Tps over 70% as a start point .

The idea was to use s/c up to about 3.5k (once turbo is spooled) then disengage s/c and let turbo do the work
So was gunna set the s/c to turn off at either 3.5 k or a set pressure, or both

Use the supercharger to help spool up the turbo, by running supercharger through turbo with a valve opening a air supply bypass once the charger becomes a restriction. Otherwise your other plan looks like it will do the business.
Waiting to see the out come, keep at it.

The eaton m24 has an output of 0.4lt per revolution at 20psi. The td04 delivers 265cfm at 15psi.

The eaton m24 has a cfm of 211cfm at 15000 rev/min. The td04 has a cfm of 265cfm so there is a restriction.

Due to the position of the charger, pumping that into the turbo is impossible, not without running boost pipes thru the wings (Would look cool!)
So the seperate inlets is only pption

I'm abit lost sorry, you were running turbo to charger to intake and now plan to run charger to turbo to intake but space stops this so you running them in parrell with the charger disengaging effectly when the turbo creatws more boost?
So, and feel free to spot me down, can you not run a Y into the inlet one side from the charger one from the turbo with a flap valve arrangement do as the boost levels balance / increase over the other the mechanical valve opens or closes each feed line? Then micro switch the supercharger flap valve so when closed it will open the bypass and bent the pressure?
I'll draw it out and show my working if that makes no sense.

I'm gunna go charger into turbo now.
Made some space and got creative with the grinder and welder lol
I'm also swapping the front mounted intercooler for a starlet too mount , for 2 reasons
1- much shorter boost pipes , there's loads at the moment, looks cool, pointless though
2-it draws to much attention from the wrong kind of people, and police (not all mods declared yet!!) I've allready had it broke into once, smashed up, and had another load of travellers who are keen on stealing it go over it the other day two, good job my Neighbour saw them!!

........progress Supercharger into turbo .....inlet pipes where air filters will go.TB will open when supercharger is off, giving a direct air feed to turbo

Just been looking and thinking about your set up and how I would go about it on the ginetta. If your feeding the turbo which I would too do you need the clutch pulley? I'm thinking ill be ok if I leave it spining as itll be diverted still by the mini bypass and the turdbo will be getting fresh air from atmos. The mini valve, could that be also operated by the actuator on the turbo? Block diagram shows what I was thinking........ oh actually that wouldn't work would it, negative air before the turbo fresh air would work where the sc becomes a restriction it would create a vacuum but would that continuously fluctuate or stay open the amount it needs to increasing as the turbo pulls more air?! All very good stuff, id need to make a new manifold set up. Mine feels restricted at top end over 100 mph now.
