I know I am the reject on the forum with the only Edelbrock lol but still. Figured I would contribute. Mods are in my signature but on a Mustang Dyno with a 3.25 inch pulley (82.55mm) and 6.5 pounds of boost on 91 octane I am putting down 575. Going to pulley down to a 3 inch soon with e85 and hoping to put down about 680 with 10 pounds of boost.
