2007 Dodge Charger SRT-8?

[chris]

have a 07' Dodge Charger SRT-8 and i have a magnacharger installed with Edelbrock Exaust and Holley Carb it had a 426 6.1L Hemi Engine in it before i pulled it out iu put the 8.9L 540 Hemi in it instead i get exactly 1,165HP with it, it's a nice car believe me but for some reason when i stop the car the supercharger takes about 20 seconds to wind down all the way is tht normal??? if you want to get details feel free to im me but iwas just making sure this was normal

That sounds very weird considering the supercharger is belt driven.

Have you had anyone else look at it?
