remember all turbos have lag, the time it takes the engine to to pump the air into the cylinder when u press the gas down.
Since the supercharger is mechanical there's no lag.
Turbos also save much more fuel than superchargers, becuse the engine mostly only uses the turbo when u accelerate hard. And the supercharger is always engaged, unlike the turbo.
At least that's what I think I learned when I worked my Turbo GLH, Lebaron turbo and my little knowlege of superchargers.
if you have a srt6 then you should know your stock supercharger doesnt engage until it hits 2900rpm or above. It also engages below 2900rpm if there 44% of engine load or more. So anything below 2900rpm or 44% engine load the supercharger isn't engaged at all.
Also one of the reasons why you can get good hwy mileage. I've gotten as high as 27mpg in my c32 when it was stock...when the epa rating is 22mpg.
