How does a setup like this even work?

Right? 3 would make sense, or even 6, but 4?

They are compounded so the exhaust that would be the down pipe feeds the big turbo which spools later

So it’s like an RX-7 setup but doubled?

No rx7 uses a twin turbo setup where the turbo manifold splits and feeds both small turbos at the same time. They spool at a lower rpm because they are small but make the boost of a slightly larger turbo.

This is a twin sequential setup so the two small turbos spool lower, their exhaust goes through the big turbos and they are bypassed via the waste gates at a certain rpm or boost level

to allow unrestricted flow to the big turbos. This pic is a sequential setup from a power stroke v8. It happens to pressurize the big turbo and blow through as well, using a variable vein inside the turbo.

Oh, cool.
