Twin screw supercharger pro charger or single/twin turbo?
It depends on what you want it to do.
Twin screw charger will give you a lot of boost almost from idle and up. Good for quarter miles in other words lol
A single small/medium turbo will give you a balanced street car that is drivable and economical but with a bit more grunt up top.
Twin turbo's if large enough, will give you significant lag down low, but a large amount of boost up higher revs, due to fuel economy issues it is more suited to track use in my opinion.
