yeah I have heard so many ppl say it is bad to lighten the pulley or to take some metal off the pulley.
even keith84_uk read some stuff but they still what to do it.
for me I think I will leave it as it is
if mod the pulley you have to mod alot of stuff on the engine to keep it strong and not fall apart

Seasons greetings from beijing enjoying some snowboarding, any pressies like carbon fibre bits from the wife?
KC man, I tested a 323i before, it has some go, I would recommend some new alloys like yokohamas they look good in graphite, would spice up your car
Cheers

I reviewed and seem they all not only change the weight of that pulley , but also the ratio and size. Seem issue came from incorrect ratio and size. Please correct me if I am wrong.

Lets discuss with AK47 and see what he says. I was totally lost while reading the article.

BTW, I will be at AK47 on Monday afternoon to install the sway bars & the cables for the HID fog. Anyone want to come down for a chat, feel free.

Hi guys, after staring at my recently "whitened" angel eyes last night for sometime, I have decided to change it back to the original ones, the reflection tubes of my angel eyes seem to have oxidized or something, it is a little yellowish still even after I changed to the led version

Anyone interested in those led lights?

damping is the key, the stock pulley absorbs vibration from the engine, especially that at its natural frequency. you need to find out whether the mod part has any damping. if it doesnt, then you need to find out what effect it would have to the engine running without damping.
