So the downpipe of the small turbo is the exhaust gas feed of the big turbo?
If so, that must give the small turbo a lot of back pressure in the downpipe?
The big turbo then blows into the air intake of the small turbo?
So, all the charged air flow still goes through the small turbo?

Do turbos still work like that with back pressure in the downpipe and boost on the air intake?
What I mean is: do you think the small turbo will spool as fast when its downpipe is connected to a big turbo with a large turbine wheel (restriction)?

Very curieus if and how effective this works.

You posted just before me! Awesome pics btw! 1000 thanks!
