New E55 Supercharger power pulley/clutch!
Man, I hope someone gets this s/c pulley made!

LOL havnt tried doing a burnout yet with the TCU. I'll give it a try sometime. Before it was kinda hard to do at the track. I would floor it with the brakes applied and it would go nowhere.

My 05 will light them right up instantly but only for a second then it cuts power. I always just powerbrake the car for a second then let off the brake and stay in the throttle to spin while pulling forward to the staging light at the track.

I should have a an exact weight reduction by using the new Super S/C pulley. Should be at least 30% or more of rotational mass removed!! That means less load on the engine and about 2 times less on the Supercharger! Rev up should be quick/crisp, boost will come kick in lower and quicker.

I am a little confused so set me straight gents. Is this esp intervention (boost bleed) only seen with cars running more boost than stock (05 & 06)? What is the stock max boost anyways?

I believe a 6-8mm decrease. Brooke stated that running a 180mm lower and the smaller upper would be equivalent in running a 186-188mm lower but would rev up WAY faster. Adding this plus a stall and TCU upgrade, would make things even more violent.

Yes, you would hope that would fix that launch managemnt but must have not.

Any future plans to experiment with adding 4matic to one of these 55's to put down all that extra power without having to DD with drag radials?... i would love to see a AWD w211 e55

What fun is that? The AT is not enough, now you want AWD too?

My assumptions:
90mm S/C "stock" pulley (need to confirm)
180mm Crank pulley
My calcs:
Pulley ratio = 2.00:1
Max S/C RPM @ 6500RPM engine speed = 13,000RPM
A 186mm lower pulley would have a ratio of 2.07:1 and a S/C max of 13,433RPM
A 188mm lower pulley would have a ratio of 2.09:1 and a S/C max of 13,578RPM
If the smaller S/C pulley has a similar effect as the 186-188mm lower pulley, then the overall pulley ratio should be in that 2.07-2:09 range even when using the 180mm crank pulley...... by my calculations, an 86.5mm S/C pulley & 180mm crank pulley nets out to 2.08:1 ratio. Right in the middle of those other pulley combinations.
It seems that a 3mm reduction in the upper pulley nets the same improvements as a 6mm increase in the crank pulley, which if you think about it makes sense. There's a 2:1 ratio difference in those pulley sizes, so changes in the smaller pulley should be more dramatic.
One of the experts can chime in here.... I may be completely off-base with my thinking and numbers.

some traction ala gt-r/gallardo would be nice

That's how I read it too, but mathematically the upper pulley doesn't need to get much smaller to have a dramatic effect.

90mm S/C "stock" pulley (need to confirm)
180mm Crank pulley

Pulley ratio = 2.00:1

already have an S4 thats faster than 2003 RS6s 
plus the older c5 rs6 had very expensive DRC issues that made airmatic failure look cheap
if the newer 2008-2010 RS6 v10 TT came to north america i would have been looking at it since they are running around 6sec 60-130mph on moderately tuned versions pushing 800+ awhp... but as usual europe gets the cooler cars and it didnt make it here
AWD has its advantages when HP gets high... drifting is fun for a parking lot but not when trying to out accelerate another car

My SC clutch is toast and I've been planning on paying for the overpriced $1K MB assembly so count me in for one of these. This pulley and the TCU flash will be the next mods for my 55. Any idea on price yet?
