Contour Enthusiasts Group Archives Forums Modifications Duratec Performance DMD or UR pulley?

thinking of a cheap mod to do. what do you all think about
DMD's versus Unorthodox crank pulley. i have read that dmd
while reduce vibrations and decrease stress to the crank, and the light weight of the unorthodox pulley i think would
due the opposite with no vibration dampning at all and more
stress on the crankshaft, but with improved power and revving ability.
I am leaning toward the DMD from spmotorsports. i would rather have increased engine life and reliablity and smoother revs up high then have a fast revving but jerky engine.
let me know what you think!

DMD without a doubt.

Then later you get the lightened PS and Alt pullies. Best of both worlds.
