:speculation only:

i would imagine that with the powder coating, you are shooting for a glossy apperience, correct?

this will likely reduce the friction against whatever belt you have running through the pulley.

anodizing looks cooler anyways:p

if you could powder coat everything but the frictional surface, i would say go for it

Powder coating isnt going to increase your weight barely at all (I am talking like maybe 15 grams here) and its going to be a hell of a lot cheaper then anodizing. With powder coating, a thin layer of ionized powder is sprayed onto your pulleys and then is baked on at about 400 degrees. With anodizing, your pulleys will be dipped in a solution of liquid methanol bicarbonate and then an electric charge will be run through the liquid. The varation of the charge will give you different colors (visible spectrum 400-700nm). With powder coating your pullys will not have as smooth of a feel as they originally did and with anodizing they will feel exactly the same. This may cause a difference performance wise, but I dont think that it would be such a differece that it would justify the extra cost of anodizing.

i want to powdercoat my z32 brakes. im going for that glossy appearance, but i dont want it red. i just want it a glossy black.

The GReddy pulleys are already anodized blue (obviously), you can't re-anodize something can you?

g'damn this man has some knowledge...he's me new best friend

I dont beleive either will effect your performance so drastically you would notice a huge difference. However, powdercoating will reduce friction slightly, which may result in slippage during high torque. BUT, i say BUT, I find it very diffictult to beleive that, because; if your belts are tight enough, there is no way in damn hell you are going to loose contact surface...no damn way. Matter of fact, I put a peice of plastic on a pulley to demonstrate this on my friends civic, it spun and spun and spun and noticed no slippage.

You can re-anodize them but it will be uber-expensive, evolves reverse charging the metal and I know of only a couple places in the southeast that can do it and even then the finish isnt as good as it could be.

Yeah, if you guys got any chemical/organic material questions, I am your man. I gots me a major in Biology and a double minor in chemistry and organic chemistry. Plus I worked in a machine shop for 3 years so I can answer some questions there too. Might even be able to get some milling work done if anyone needs some.

I wanna be this guy....wow. Never knew biology was so cool. Probably shouldnt have slept through high school...damnit.

**** damn...

obviously dude.. (that stuff is chemistry)
lol

[FRpilot]

isn't biology the stufy of living organism and ish.. what you want to study is chemistry and mechanical engineering. haha. but no matter how much i try to relate it to cars, it is still so dam boring to me. :hammer:

[Burmonster]

Ha, I dont mind the whole biology and chemistry stuff but I cant stand the whole engineering thing. Your right, it is way too boring. At least with chemistry you get to make cool stuff( i.e. I know the chemical compostition for LSD and crystal meth...not that I would ever make the stuff and then sell it for profit to fund my car habit.........)

And to answer your question Swoop411, I think the Simply Green stuff involves an enzyme catalyist. While the material it is in (mostly water, some methal nitrate, and other goodies) is chemical, I am pretty sure its the enzymes in the goo that does the work. I am not 100% sure on this, and now you have sparked my intrest and I am going to do a background check on this stuff, I will get back to you on it.
