i'm not here to talk bad about Superchargers....i promise
. and to be honest, i almost went to the JRSC route. i did all the research to it and i came down to a decission of going GReddy instead. i know a few friends who switch from SC to TC. as far as power band, it all depends on the turbo. i have a quick spool TD04-H 15G from the GReddy kit. i do not suffer on any kind of lag at all. it kicks in around 3500-4000 revs.
