Twin charging

[Alexdaredevils]

I'd like to try twin charging (super and turbo charged)

Its for a Volvo Amazon project I got

I plan on using a Mercedes M111 2.3 Kompressor with Megasquirt 3 ecu

So i was thinking of using the Supercharger that comes already on the 2.3k engines with the clutch system, having it switched off at idle to save on fuel and wear etc, engaged at say for example 1500rpm using a megasquirt output feeding into the turbo intake helping it spool up quicker, once the turbo is sucking more air than the supercharger can provide switch off the supercharger with the clutch system to stop it making heat and sapping power higher up the rpm range, between the supercharger and turbo have a Y pipe, one side with an air filter, one to the turbo intake and one for the supercharger side have and electronic throttle body also connected up to the megasquirt switching the whole supercharger side off diverting air for the turbo straight from the air filter.

Is there a better self adjusting using some sort of vacuum system for the switch over?

Will I need a intercooler/charge cooler between the supercharger and turbo or will just after the tubo be enough?

Im not great at explaining things but in my head I think it makes sense?

I know its over complicated and just one turbo will be fine, but where's the fun and challenge in that?

Any tips greatly appreciated

Ok I'm all ears and appreciate comments

The S/c will most likely be a Eaton M45 or a M65 and from I can work out the M65 has a bypass built into the attachment, would it be worthwhile to make use of this? The turbo will most likely be around GT2871/GT3071 size, based on that info would you still have the turbo blow through the s/c?

Thanks
