And the parasitic loses of a s/c are always way higher then the losses due to backpressure increase by a turbo. Don't forget that otherwise wasted engery (in form of heat) is used to drive the turbo. The overall efficiency of a turbo is higher than that of a s/c which doesnt mean that I would roule out a s/c - I even prefer it since you can reach a certain amount of gain with less cost and less labour and with less parts (less parts = less possible source of trouble).,

Having said that, a birdy told me there will be a press release later today...
