Had my S just under a week now. I know it has an aftermarket exhaust and GRS intercooler but it certainly feels a huge amount quicker then the standard S i drove at a dealership. I had a
JCW mini a few years ago and it only feels a bit slower then that. I'm wondering if a previous owner put a pulley on, how can i tell?
Also does the engine have to come out to fit a new pulley?
Thanks in advance
