Jeff, i removed the supercharger just before selling to him, but it will back on when i'm done another thing is it had a rattle at the front snout(only at idle)which had the buyer worry so i called Holley they said it was normal due to wear but rebuilt kit will get rid of it so i bought a complete rebuilt kit for the snout($150.00) as i'm very anal about noises like that, well the guy ended up being a $1,000 short so i kept it
