can i hi-jack this post too?? i have been wondering about the same thing but a UD crank pulley instead of a DMD and no alt pulley?? i know that the DMD is better for vibration and engine safety but i dont really have the time or money right now to do both and i am getting the p/s soon. my stereo is a wee bit to much for an alt pulley so will i be ok? im sure i will notice small gains but ive blown my engine once already and id like to know opinions for peace of mind
