Variable Vein

[ISPKI]

In case anyone was interested what a next gen variable vein assembly looked like.

Side note: how does one upload a video?

Adjust exhaust flow over the turbine wheel for varying response.

Keeps the turbo spooled and in the sweet spot longer than a fixed vane. You can attain boost earlier on the low end, and prevent overspending on the top end, without super heating the air. Pretty neat! Check out the Turbonator by DPS. First true aftermarket VGT turbski

Somebody scan that qr code

The top ring with the fingers and the square block rotates as you build power and increase throttle demand which in turn effectively increases volume in the turbo. I think it would behave as though the CFM and A/R would increase as it spools higher.

I think the PSD turbos have been using similar technology starting with the 6.0 turbo. They call that a "variable geometry" turbo.

Think of it as changing the exhaust housing size.

That is probably the best way to look at it. If I could figure out how post videos then I could show it being welded and how the veins operate
