I have a C GT and already have the AEM alternator pulley. I just bought the Unorthodox SS Kit. The Unorthodox alternator pulley is smaller than the AEM. My question is for HP wise (Don't care about mix brands just HP) would I get more if I change the underdrive and keep the AEM alt pulley. Or should I change the alt and have both be Unorthodox. Please let me know since I am puzzled.
