I have M90 superchargers polished for $250.00 labor. I also add in FREE chrome plating of the supercharger hardware bolts, PCV cover, and snout fill/drain plug for that extra touch of bling if customers pay in full upfront. Throttle bodies, stock, LS1, N* etc. all run $80.00 to polish. Want more info, or details, just shoot me a PM or email me at GR8racingfool@yahoo.com
how much do you charge to polish a blower and how much to polish TB??
