Thank you for your answer...

The fact that i didn't choose the srt6 in the first place was for the spoiler. I wanted the back of the car to be rounded, without the spoiler... that's one of the things that made me buy the crossfire in the first place.

Sorry for bringing back the discussion on the supercharger, but I did a search on the forum. I haven't found anything interesting about it (most of the post when i type 'supercharger' is from the SRT6 forum). I may be missed the thread you're talking about... I'll keep looking.
