The turbo brings boost on as quick as possible...
Whilst it may not be making boost right off idle, it will bring full boost (and hence full power) on quicker...
The turbo can have boost adjusted by the flick of a switch...
Super charger is a matter of changing pulleys, harder, more expensive...
If you set the super charger up to be running full boost off the mark, you will need a bleed valve, therefore, the RPM of the SC is in accordance with the engine RPM, therefore, to make that HIGH boost at idle, you will be driving the supercharger VERY hard, a VERY easy way to over drive the supercharger and blow it to bits...
Turbo is way cheaper once setup...

what bullshit
SC;s are positive displacement devices. ie full boost is there INSTANTLY, since the SC is mechanically driven.
if you have a 2L SC running at 3:1 on a 2L motor, you will ALWAYS have a 3:1 pressure ratio, regardless of the rpm (relative inefficiencies aside)
bleed valve.... LOL, aren't bleed valves what ppl use to reduce the effective pressure opening a wastegate on a turbo system?
no point spreading mis-information here.
and if all you are after is kw. go turbo. if you want drivability and near maximum torque from idle, go SC.

Non bull shit...
Full Boost is NOT instant...
The Super charger has to spin up linear to the RPM of the engine...
At LOW rpm, Full throttle, the engine is wanting more air then what the SC is suppling compared to at Full throttle on high RPM...
Boost still has to build up, but builds up more linearly then what a Turbo does...
As for the bleed valve, there are systems available (No bull shit) that you can over drive your Super charger more then normal, to make boost earlier, yet as it hits a specific boost, the valve opens, and starts to leak air out (just after the SC, so problems of dumping fuel are a non issue)
The problem there becomes, if you BLOCK the valve, Boost will build up heaps... IF the supercharger can hold togethor with the centrifugal forces acting on it...
SuperChargers are only able to go to a maximum RPM...
