New E55 Supercharger power pulley/clutch!
Many shops and MFG companies said it could not be done on the 55 supercharger pulley but problem solved!! This is a complete new pulley, upgraded bearing and clutch assembly! My first run should be ready in 3-4 weeks, I hope! I will have pictures for you soon.
I worked on this problem for about a year and finally sent the stock E55 pulley assembly off about 6 weeks ago to Performance machine , along with my ideas on what we need to make this part be succusseful! More boost , less weight and a great price.. Also included material ideas and some coatings to cut down on belt slip. Win, win!! I verbally agreed to have 50 run (min they need to make a run), so my cost would be low on my car and all my friends get a great system too! I also am looking at two boost levels for this power pulley and would run 50 of each parts then. I have the cash, so don`t mind fronting it for a great product that no one else gas or been able to make!
This is a game changer and an easy install. It also replaces the stock with more boost, less weight and at much better price.
Like to also thank Shardul for his help with shims and MB specs.

I'm definitely interested in this as well. Please keep us all posted and if you know an approx price please PM me that as well. I'm in the market to upgrade the Crank pulley but this may be a better alternative since I was probably only looking to go up to 172mm size.
Thanks,
Chad

Since the clutch is computer controlled, any plan to maybe have a centrifical clutch / cheater on ECU? I hate the fact that the ECU controlls when / how boost is applied. On other SC cars, if the SC is spinnin'.. It is boostin'

168-170mm on power pulley 1 boost and 175mm- ish range on power 2 pulley size.
Bramage, no plans for a ECU clutch cheater but if you figure it out, I am subscribed!
I will have pictures up soon. The special coating will help cut down on belt slip and help with heat. (I have friends at NASA).

Add me to your list Brooke
In terms of cheating the clutch / Boost bypass. I believe we share the same ECU with the C32 - It has no bypass throttle body.
That tells me either: The seconday TB could be deleted and the ECU would still be happy- Or - There is a way to turn off the bypass in the ECU accomplishing the same thing: Happy ECU
Once the bypass is gone, I think locking up the cluch would be worthwhile. The ECU could not bleed off the boost. Hmmm....
In fact, maybe an easier (read ghetto) way of doing this is simply block the top of the secondary TB, allowing the butterfly to move, but no bypass. Airflow would be constant- Idle and low RPM might be nasty.. OK, now Im just thinking to myself. If we did this, the car would run like crap, because it uses the bypass for low load operation.. The C32 doesn't.. There is a way to solve this, and from there, the clutch can be addressed. Sorry for thinking in your thread!!

I'm sure lots of testing is going to have to be done to try and find the correct balance between crank and s/c pulley? With complementing mods of course.
