As kev already said supercharger v Turbo is like night and day. I've been down the same road as Kev with the charger and turbo, your best bey is to try and going out in a Turbo VR and a Charged VR and see for your self. As for economical, forget the charger .The drag on the engine is a joke, then the noise , belt slip, belt shredding ,crap torque , im sorry there no good points about a charger can't beat a well setup VRT A good setup not cheap but well worth it
