    Last I heard from a local that has a actual GNX he said all he has done to it is a K&N filter bolted to the turbo and made 293 RWHP and 367 ft. lbs...stock everything minus that filter on it...on pump 92. So you got me...that is like what...350 something to the crank horsepower wise and nearly 450+ tq...yeah...they were 12 second cars from the factory with a good driver.

    Theres a reason the GNX cost a lot more than what it should have for taking a car from ~230 HP to 276.
