V and inline configuration engines ahve a lot of differences. The main reason behind a V configuration is that it makes an engine compact and less space is need longitudanilly. During the 80s it had a performance advantgae over the inline engines but that was over come down the line with better performaing inline engines.
Another reason was the revival of the inlines was due to them being stronger blocks and mostly made of iron rather then aluminium alloy. And iron blocks can withstand higher boosts then alloys.
Turbo and supercharger are both forced induction systems which pressurize the engine compartment for extra power. But both work differently.
Turbo is driven by the waste hot exhaust after the combustion and is found to be more efficient then a supercharger since the super charger runs on power rubbed from the engine crank. Turbo has lag and superchargers dont but turbo is capable of reaching higher boost and charger is not.
So there are a lot of advantages and disadavntages. I say look up some old posts and you will find a encylopedia of information.
