I am seriously debating picking one of these up. I love the idea of making her even faster and I love the supercharger whine down. My only concern is for 2700 it doesn't seem to add a whole lot of power. I saw a guy with a black one at the ford 100 and he had the supercharger and was proud of a 183 at wheel horsepower. I know these things are underated at 170 to add 13 horses for 2700 that seems a bit outragues. I have never dynoed mine so maybe that is a huge jump. I know the 170 is flywheel but is this kit really worth the money???? I am debating adding a mild 50 shot of nos for those quatermile runs. That shouldn't tear up the engine to much. Or maybe I will go propane.
