Just installed supercharger pulley
The eurocharged instructions are good but I will post any extra tips I have. First off I took a photo of the belts so I could get it all back together the same.

Next you need to loosen the tension to get the belt off. I put a 15mm spanner on the nut of the tensioner pulley and used this instead of the E10 torx the instructions say to use. Pull the spanner towards the left of the photo ie anti-clockwise/counter-clockwise. You should release the tension before the nut un-does itself. I found it easiest to slip the belt off the large black pulley just to the left of the crank pulley in the photo above. It required much less force than trying to take the belt off the recommended pulley above it and to the left of the coolant line.

I could not get the stock pulley off. After 10 years and millions of heat cycles it does not want to come off. I tried all sorts of stuff. The ridges in the pulley are too small for a pulley puller. In the end I put a screwdriver angled against the outer pulley thread and hit it with a hammer. I don't recommend hitting a $16,000 supercharger with a hammer but I couldn't find any other way. It eventually slid off. I had to take the clip off and lower the rubber coolant line stopping the pulley from coming off the very end. You can lower the hose off the metal pipe about 3/4" without risking coolant going everywhere.
Eurocharged and stock



This is what you get off.

These are the shims everyone talks about. They are the last thing removed. The adjust the gap between the pulley and the electromagnetic clutch. I did not need any so I did not put them back.

New supercharger bolt. High grade titanium. The stock one has a hole through the middle, supposedly for oil discharge. Mine was blocked with crap so I guess it can't have been too critical.

All tightened down. My only issue was that the new pulley does not appear to sit 100% straight on the supercharger. The following 2 shots are with it 90 degrees rotated. You can see the gap is enormous. I am not sure if this matters or what to do about it.

Not so good.

So anyway the car runs. I definitely have full boost. It is raining but I went for a quick spin and the orange triangle was lighting up all over the place...
So the clutch definitely engages ie lots of loss of traction. What I am wondering is if it is disengaging correctly. Under what circumstances will the pulley turn but the supercharger not be turning?
Or does the supercharger always turn a bit even with the clutch disengaged?
Have you remote tuned?
The s/c 16k? here in AU yep easy the sealership would try n slug that. First and last visit to the dealership I was quoted 4.5k for assembly 59: which is the pulley,shims and bolt. Insane.

Glad its nuts, I am looking forward to it. I don't think it will take long to convince myself I need a quaife for christmas.

The OEM bolt has a hole that runs right down the middle, I'm curious if that hole is required. I'm going to have a hard time taking the clutch back off and once I do the bolt will be useless so I am trying to figure out of this Titanium M8 bolt is a viable replacement or should I keep hunting for an OEM unit? I called the local dealer and they said if I want the bolt I have to buy a whole new clutch for $1,700!!!!!!!

Have a look at the link in post 4 if you haven't already. Bryan has had the same bolt for years, he gave me mine.

Do not contact the dealership, they will want you to buy a new supercharger just to get your hands on that elusive bolt.
