LOL. I thought people were talking about me...my ears were ringing. :P
Just to clarify, anything that was aluminum (SC housing and snout) or stainless was polished. Items like the TB bracket, the PCV cover, and plug wire holders are regular steel and were chrome plated.
As for performance, there is none to be gained or lost with polishing. It'* all about eye candy.
It'* a project I've been patiently wanting to do for my GTP for 2 years now.
In case anyone is interested, Jason Farnsworth from ClubGP.com offers this for $150 to polish a full SC unit. An additional $50 to have Jason to completely disassemble the unit (snout shaft from the snout housing, pulley/pulley hub removed, removing the rotors from the rotor strip,etc. He reassembling it after the polish is complete. You must provide a new snout seal.) The reason for having it disassembled is that you do not want the buff and polish compounds getting to the bearing areas. It'* like fine sand particles.
harofreak00 - I am kicking myself now for not getting in on that valvecover buy back in May. :(
Any additional questions, please post or PM.
