Alright our 118d has a single turbo engine and has quite a lot of lag. Basically below 2000rpm there's almost no engine.
Lack of charisma can be fatal.
Visca Catalunya!

Thanks a million. I always appreciate your expertise and vast wealth of experience. How are you doing today?

wow....
comparing similar years, 03-06 G35 Coupe and Sedans and 350Z's pre dual intake z's, they have the same exact intake. The only difference is that the g's come witha sound baffle on top and it drops down into the engine bay. The 350z has a straight pipe. That difference is just for sound. most cars have a sound baffle to restrict intake sounds. you do not feel any power gain from doing this. Both G35 and 350z have the same air filter, same intake. the only difference is the "z-tube" from the MAF to the throttle body.
Gone:
09 Ducati Monster 696
09 Audi Q5 3.2
03 Infiniti G35 Sedan
07 Honda Civic Coupe LX 5spd
Current:
10 BMW 335d
12 Audi Q5 2.0t
10 VW Jetta TDI
11 Ducati Monster 796
z-tube seems to make a difference in how the air flows as far as throttle response. Maybe I am just feeling butt dyno. Just maybe.....
A turbocharger has both a compressor and turbine impeller and the two are connected with a shaft. It is the same principles that apply to power plant design just on a smaller scale. The turbine extracts energy from exhaust gases and uses that energy to drive a compressor.
Reading stadium as "stage", then I wouldn't say it is impossible. It may not be pratical, but I am sure it is possible. Given the need anything is possible.
For example, look at this old work done by NASA to run a Rotax 912 1.2 liter 4-cylinder general aviation engine at 90,000ft.

You basically have a three stage turbine. Since they are only trying to maintain 1 bar of pressure in the intake manifold at altitude it doesn’t sound so impressive. That is until you see what it looks like in the lab.At 90,000 ft, ambient air enters the low-pressure turbocharger at -65F and 0.5 inches of Hg absolute pressure. Assuming average compression ratio of 4 per stage, outlet pressure to the coolers from the low, intermediate, and high pressure turbochargers amounts to about 2, 8, and 32 inches of Hg. Allowing two inches Hg for cooler losses, this supplies air to the intake manifold at 30 inches of Hg.

You just went a bit outside the point there, but, that's ok, the DEI invention was thought up by some idiot probably while watching fast and furious, the second it was posted on a forum it became an instant internet classic.
The 'it' could work doens't exist, it doens't work, it will never work, if you change anything with it, it no longer is was it is.
