Will the pulley retain the OEM Nachi bearing, or hopefully something of equivalent quality.
I know it was an important factor to use that bearing when replacing it on the stock pulley.
Thanks, about to preorder as well.

no intention of anything, but alot of guys were installing smaller S/C pulley here in UAE since 2009. i think it was stock pulley that was shimmed to a smaller one.
the S/C pulley they used to sell was about 5mm smaller than stock and for $1800, i don't know where they were made or manufactored.
it is easier to install and better than adding extra load on the cranck.
but i would recomend to install also S/C belt rap kit with it.
great things i am seeing that are being made for 55k since i sold mine.

This is a complete new pulley assembly and bearings. Better than the factory assembly. IMO. Lighter, smaller and great bearings!
I developed a belt wrap kit and test fit it on my car before the Texas mile. Easy to install, top quality materials and bearings. Was going to dyno test on another car but have not had the chance yet. Kits are in the early production stage right now and many of the parts are completed. New belt sizes are also in and ready. Great kit and perfect amount of wrap!!!

amazing my friend, it is side by side with my 505rwhp E55k i had, called the new owner of E55 and tested it from rolling @ 60km - 220km. a true beast with the performance package. and will mod it soon i tried with an SLS and was a tad faster until my limiter hit @ 250km and he passed by. also tried wth SL65 Black series and he was ahead of me by 2 cars length untill my limiter again hit @ 250km.

I have custom 82 mm SC pulley (-8 mm from stock diameter/ equivalent to 168mm crank pulley) for nearly a year now on E55 and for 5 years on my SLK. Been there done that. Look at my signature and look at the thread "ideal pulley design" from some time ago...https://mbworld.org/forums/w211-amg/...-design-2.html
Calculation is also pretty simple;
Stock ratio: 154mm crank and 90mm SC pulley at 6500 rpm give us 154/90x6500=11.122 SC rpm (on SC INLET shaft where clutch is sitting on).
Stock crank pulley fi 154mm and custom 82mm SC pulley give us 12.207 SC rpm.
168mm crank pulley and stock 90mm SC pulley give us 12.133 SC rpm.
So my 82mm custom SC pulley is the same like 168mm crank pulley, but with MUCH LESS parasitic loses and MUCH LESS stress on the crank.
Keep in mind that internals of our SC spins even faster because of SC internal gearing.

pencil me in too as my s/c pulley is starting to throw out some muck so i think the bearing assembly is going south...
if i ran just this s/c pulley looks like it would be like a 168mm crank pulley equivilant so would you guys be teaming up with E/C on this for tunes? i assume i could just get a 168MM tune with running just the s/c pulley and call it a day ?

It's something else. The "typical" pulley is the lower one that is on the crank. That's why a larger one is better. This one is up top on the supercharger itself, which is why a smaller one will make the s/c spin faster. The lower weight is also a good thing. Combine the two for winning.

Here is a hot off the press sample picture. One really cool feature is the over 30% in weight reduction !! Stock SC puley is 3.5 lbs and this is only 2.5 lbs!! This is huge for getting up to power quicker and lowering streess on your SC components! This super SC pulley will put you equall to a 170mm pulley. (stock is 155).

Yes, I used some really good engineering software to pre-test some design ideas and make it worth the effort. Again, this is a complete new CNC made and performance improved SC pulley. I cant wait to feel the REVS on my new engine build!
