Re: Is there a KKK site? Some questions about turbos...

Shelby used a turbo with variable vanes. There were vanes on the outer
radius of the cold side that would rotate towards the center effectively
narrowing the nozzle's volume. Sped up airflow through the booster
principle. At higher speeds, the vanes will rotate towards the outer
radius. The axis point toward the center, so my explanation is kind of
tough to get. But at high speeds, just think of the vanes looking more
like a circle. All lined up end to end. Increases the volumetric capacity
to move more air at higher speeds. This is how you get a turbo to work
well at bottom without sacrificing top end. Close to nil turbo lag.
