Installed the underdrive pulley yesterday, not expecting a huge difference but every little bit helps. One interesting note is with the smaller pulley I should have no problems bypassing the AC. The thought is to bypass the AC for 9 months and only send power to it during the really hot months. AC deletion is not really an option, my wife sometimes drives the car and I sometimes get what they call "pitch burn" at work and moving air really agrivates it. (Imagine one of the worst sunburns you have had
