I have been tossing around the idea of having my stock s/c pulley milled down since trying to acquire a C3P is almost impossible and the ones offered by eurocharged are still on pre order.

I originally started out wanting a co worker of my dad's to see if they could make a pulley like ours from stock metal.. ( this was almost a year ago).I couldnt get enough feed back from the few sights I posted on so I never really pursued it any further.

Well I had to go to Austria last week for work and figured that was a good time to have my stock s/c pulley CNC machined down to 68mm. Turned out GORGEOUS! guy did a great job! I took some comparison pics of my spare stock pulley and the modded pulley.

I changed the pulley out last night and ran the car at idle for about 1/2 hour to check the belt and see if any residue was showing up from belt wear. All checked out so I drove it back home, 250 mile one way trip, car ran great! No belt residue or slippage. I can feel a definite difference in the mid range to high end torque, car pulls harder and accelerates faster. Very impressed! Now I just need to follow it up with a tune!

One thing I did notice: My power steering pump used to whine, really bad when car was cold, but whine consistent even when warm. though when warm was not as noticeable. After changing the s/c pulley the whine is no longer there Any ideas?

Nice, I have been pondering this thought for such a long time. There have been others that had success doing this also. Do you mind me asking how much it was to get it done?

mine was no charge cause my dad works with guy and has helped him with his cars before. But I could find out what he would have charged had that not been the case.

AMG3.2

Yeah that would be great!

I will email my dad and he should be able to get back to me in a couple days with an answer.

I will post pics when I get home from work in a few hours.. the quality is just great imo..

nice, I look forward to seeing the pics

you need to change the power steering fluid.

I did this aswell! Way back though. I still have it on with no issues!

loung14, that is good news! Thanks for the advice about watching the structural integrity when milling it down.

cDirtyTwo, thats what I was wondering, it has stopped now. Level is good. But I will change it.. Thanks.

So how much power do you think you gained with this pulley?

68mm is actually a mid size c3. its what was used when running stacked with the 178 crank pulley.

As far as what I have gained I am not sure, seat of the pants dyno says its a decent gain. I have noticed around town that I can easily get the tires to break loose from a 10-15mph roll. So it has definitely added some power.

Very nice pulley. I had Code3 before then changed to 185mm for more power . From what I can tell from the pic, the code3 is just a bit thinner. I think if you are not afraid, you can sand it down a bit more. I belive the code3 sands it down all the way to remove the sloppy edge portion. But of course, the strenght will be weaker.

aaahhhh I wanna get mine done so bad, but I use my car everyday and can't wait for a few days to get the pulley back from the machine shop... Anyone have a spare they wanna sell?
