NeverSayDie Posted August 20, 2003 Report Share Posted August 20, 2003 I remember someone recently posting about underdrive pulleys. I think someone was asking about gains in accel-ect. Well, I recently put a AEM true power pulley on my focus' alternator. I wasn't expecting much pickup, but when I went back to the track I picked up almost 2 tenths! Conditions at the track were the same as before, the only new mod was the pulley. I will be underdriving what I can on the Cutty very shortly!
