My one friend ask me the other day about how a DD clutch would act if you put 1 orgainic disk and the other disk ceramic. I didn't know what to tell him but i said i would post it to see if others had any experince. He has pretty good amount of power, atleast 400 to the wheels when he dynoed a couple months ago. This is in a powerstroke. Any thoughts or experince. He is just expermenting with it.
