Before you change a pulley you MUST fit colder spark plugs. Just use a supercharger pully, using both may well over do it. Remember that more charger RPM means more pressure which means more heat. Your car can easily end up running lean at high revs and melt the pistons. The R53 ECU cannot compensate enough for this, it was never designed to. You would need a remap.
Pulleys, Which one first?
My son and I have the front end all torn apart for our cooling discord system overhaul and oil pan gasket replacement. We got some extra cash for a pulley swap. But we can't afford both the Supercharger and crank pulley. omegle
A 17% supercharger pulley would be fun but I'm not sure if that's the way to go. From what I'm reading a 2% crank and a 15% SC is the best option. And I can get there eventually.
Do you guys have an opinion? Also has anyone had issues with aftermarket xender crank pulleys not having a harmonic balancer?
Thanks in advance for the help.

I had a 2% crank pulley and 17% charger pulley when I had an R53. Most people only changed the charger pulley. I never experienced any issues with either of them but as mentioned above, all of this does result in more heat. I had a bigger intercooler from Airtec and cold spark plugs.
