I thought turbo made fule economy worse even when there off but they are considered "free power" cuz it doesnt use the engines power unlike superchargers cuz it works on air(partially). I saw a setup on a ustang with a twin supercharger though it looked impossible to recreate and it only made 600hp on pump gas( dont know if it was rwhp or just crank hp). I wish I had a pic but I saw it at a dragstrip.
