Anyone using the JR supercharger from Focus Central? I was wondering if I could get additional power out of it with intake and exhaust mods. Jackson is claiming at the crank, 189hp and 158 ftlbs with it on a stock engine. I understand it will be instant throttle response versus a turbo that will have some lag, but with turbos that can put 200whp, the turbo would be faster- UNLESS some additional mods can up the power that the supercharger can produce. Just wanted some opinions here.
