How to... replicate a twincharger system on a k11.

Using a supercharger from a mini r53 and a T25 from a 200sx, is it possible to replicate the SuperTurbo charging on a CG10/13? there is something similar to an electromagnetic pulley to switch on/off the supercharger?
someone has the charging scheme from a k10ST?
 
I think the Eaton M45 charger from the BMW mini would be too large for the CG engine (specifically in a twincharge where it's likely to be engaged at low revs only before anyone points out @pork 's great work). Have a look at the current VW / Audi 1.4 TSI twincharged setup and the little M24 charger made specially for it.

I've been thinking this through, as a dream for the future...

M24 charger from tsi
And tdo4 turbo

Electro clutch was a pain to get right, ended up with a much simpler system running both at same time, but with various bypass routes

Was huge fun, 7psi instantly, then 10psi when turbo took over

My preference is to avoid the electromagnetic clutches/bypasses and keep it simple. Then again, it wouldn't be for a maximum efficiency build you'd expect for a road car, it would be all out performance for sprints or hillclimbs where that doesn't matter.

The biggest challenge is initial sizing and having enough wastegate flow.

Yeah, found that out the long way lol.

Ended up going charger into turbo with a 57mm throttle body bypass activated on a 7psi wastegate actuator.

Worked fine

Mega squirt copy, it's a k-data, can still buy them from Germany I think for 250 euro. Bargain really
Sorry to drag up this thread again, but can this K-data ECU be used with CG distributor engine's? Or does it have to be used with the coilpack setup of the later K11's?

Just trying to get some idea's as i may have some plans for my K10 in the future :cool:

I welded a trigger wheel to the crank pulley, and used a generic crank sensor, and the coil pack plugs, then just blanked the hole where the dizzy went
