Im hoping that if it makes 286kw @ 1.4 bar

Then it should make (286/1.4) x 1.6 = around 326kw
Im hoping its a close to linear relationship given the turbo is in its peak efficency range from 1.5 - 1.9 bar.

Someone that knows more about this can educate me.

Decided for 1.6 instead of 1.7 as i only wanted 300kw
