i have a 2005 mustang v6 with an xcharger, the rubber inside my harmonic blancer is cracked all the way around and is causing it to wobble...not good, i was looking around at replacement options. should i just replace it with a stock one from ford at $179 or with one from steeda? my only hesitation is all the aftermarket lower drive pulley are a diff diameter thus requiring a diff belt and i don't know how the decrease in belt speed will affect the xcharger. any suggestions?

Good question, I do think some guys are running a UDP with the X, but I do not know what benefit/negative it has on it.

on stock six supposed to be good for about 8hp one of the mustang mags did a test on it, the article is online.
