Backpressure from trying to drive a small turbine (in a small turbine housing) past it's choke point is what I was refering to .

Bump.

And Brettus; Can remember that you were considering another exhaust turbine wheel for your 60-1, have you tested/looked more into this. Seems to remember that you weren't too happy with transient response.

I'm Looking at a new setup entirely . I'm sure the 11 blade turbine wheel would improve response a lot though.
