Supercharging a diesel engine will give out lot less power than a turbo-intercooler combo. Hence it is employed only in trucks.
In case of petrol engines, even normally aspirated 1.5 lt engines can make 110-120bhp, so adding a bold on supercharger gives the performance without any turbo lag.
Since a diesel engine is all about efficiency, its mostly turbo in diesel land, and turbo lag is combatted using VGT etc.
