oh naw the superchargers come close to the turbos ..... superchargers for the 5.7 l are getting around 430-440 rwhp and around 440+tq ... the turbos for the 5.7 l get 500 rwhp and 550 lb of tq at 6000 rpms..... your getting little bit more hp from the turbo but the decisive factor is the tq... your puting out a beastly 550 lb of tq from a turbo. But thats from what i have seen from people who have superchargers and turbos on their lx cars.
