my twincharged project

[UrS4boy]

i have changed the AAN cams for 7A cams
the inlet cam was not a straight fit,the dizzy gear was different.i have a older AAN engine with a diizzy (tunacan) for camshaft sensor
with some heating i switched the gear on the cam
left intake cam 7A-right AAN intake cam

Good job. So left = 7A, right = AAN (just to confirm):

yes dave,the gear from my AAN is a 2 piece gear with a spring in it between the 2 gears .the rear part can move a little
the 7a intake cam have a little gear with less teeth

Coming into this late so bear with me. I'm coming from the diesel truck world with a few twin charged trucks that I've watched built.

Why is the turbo feeding the SC? The SC will be a restriction at high RPM/boost. There's also an issue with rotor flex when feeding a super with boost.

What I've seen done is a super feeding a rather larger turbo. The idea is super for low RPM and turbo for high without the restriction of compound turbo charging. So the SC, when the turbo can neutralize the the incoming air so it's atmospheric pressure, starts freewheeling. Then if the turbo demands yet even more, the bypass valve on the intake of the super opens to start feeding the turbo directly.

So it goes

Filter
Piping
Diverter valve
Super
Turbo intake

a made this setup because i had no room to make it otherwise like you have said
the sc is not a restriction on higher rpm because after 4800 rpm the sc cut out and the bypass valve goes open so boost flows from ic straight to the intake like a normal setup

today was my dynoday
everything went well and no broken pieces
this was the first pull,programmed by me on the road
on 6300 rpm there was a powerdrop caused by a to rich fuel ratio,lambda 0.65

[quattro-nick]

en this is the final pull after about 2 hours
very happy with the results,562 hp and 600 nm torque
