They have since fixed it but for them to get it wrong in the first place is silly!

yeah, but blowers use engine power to work, tubbies don't.
Though it would be better to have a smoother more consistent power delivery of the blower

Turbo's will add to the back pressure of the exhaust which will still have a throttling effect on the engine which will sap it of power.

Ahh.. I've done a little testing here too.. Actually the losses to drive an S/C is about the same as a turbo restricts the flow of the gasses, so horses for courses really.

I have to say I prefer S/C's as they are much easier to map, but they do not give the shove in the rear the Turbo does. Having said that, S/C's dont tend to run out of ooomph at high RPM's and tend to run lower charge temperatures in comparison.

Just my 2 pennies on what I found while testing both systems on the same engine
