Supercharge Or Turbo?

the debate about wish is the best source for boost will probably never end.
there is advantages and dissadvantages to alll designs, i think that the twinscrews could be the ultimate form of boost, sure they are expensive but not as bad as they used to be on money,modern tools for making the screws have improved alot,one of the biggest problems seems to be the lack of companys manufacturing them and the accessories. however i know that a company is reserching and actively testing some very efficient bigger screws ;)
