Default ? for those with a turbo or supercharged NPI engine

Just wondering what kind of times and power the guys with turbo or supercharged npi engines were putting down, compared to the pi engines.

I jus't cant see a supercharged npi being slower than just a bolt on PI, thats like saying you'll gain more power from doing a PI swap then doing a blower..............

Well a 2.2 kenne bell and a vortec are def not the same lol, but as far as a vortech npi and bult on pi , the bolt on pi is making what like 250ish hp 260 at best, the npi is like 190 stock, i definatly would think a vortec would gain more than 50-60 hp with a good tune.................
