I agree about the aluminum pulley. I have two SRTs, one has a stock pulley and one has a tune and the 65mm pulley from the guy in Poland..I had to swap pulleys between the cars recently while waiting for a new bearing for the stock pulley. Neither car seemed to care.
Thank you both for the advice! I agree, I need to look for another pulley asap. Is that company in Poland still around that makes steel pulleys? If someone could help me get a hold of them or let me know where to find them I'd much appreciate it.
