New E55 Supercharger power pulley/clutch!
you are correct, this could be a game changer. I have a few questions for you, if you are increasing boost, is this due to a reduction in blower pulley size? If that is the case belt slip would be more prone due to a smaller contact surface would it not. Going lighter in the pulley setup is definitely beneficial, could that be where the extra boost pickup is planned? There is definitely a sweet spot in reducing upper pulley size and increasing lower pulley size to maximize both HP/TQ. Coming from a rich background of the Eaton and twin screw blower, being able to manipulate the blower pulley sizing would bring major HP gains.
Either way, this is a major break through, and props to the TEXAS Playas.

We all will need clutches, so this takes care of one problem. Only takes a small decrease in pulley size to make up for a lot of S/C rpm. Belt slip will not be a problem. This also gives another option to alter boost, VS crank pulley change. 2) A lot of people may want to go up in boost by 6-8mm , change clutch and not have to remove crank pulley.
I was motivated a year ago to work on this, as my clutch is going bad, wanted a tad more boost , less rotational mass and most all of " it was postd many times that is was impossible to do" on the 55. We all know CODE 3 made the first aftermarket S/C for the 32 but they also could not pull off the e55 pulley. I think a few compabies have made since made replicas of the C32 by code 3..
I am pumped!! I am OCD about the challenges of designing/sourcing better GO FAST products for us. We all been having a lot of fun down here and more than happy to share my MFG contacts and resources to help. Lot of members have helped me out and that is what it is all about.

Price !?!
BTW, I use Finite Element Analysis to maximize weight reduction and maintain strenght. This is the crucial engineering tool to make this pulley work on the E55 after all these years. Can you image how fast your blower/engine will rev up with a couple pounds less weight to spin at 15000 rpm deal with. One pound off would be like spinning 15000 less lbs a minute at WOT .

One thing you should try to make is the ability to swap out the outer pulley without taking the whole clutch apart so when we want to add or minus boost it will be cake.
You won't believe it, the guy who do that business here ( I don't know him actually ), he buys new pulley, takes it to one workshop to work on it for (100 USD) and then sell it as new pulley for 1400 USD (around that number), the new pulley cost here 1145 USD.
One of my friends found out where is that shop and told me, when you want to do your pulley, just let me know and don't go for that Thief.
It is a shame on some persons and vendors that easy modification can be done and they force you to buy a new part by cheating.

code3 (brandon) had a break through with the s/c pulley. I was one of the very first beta testers, including his intake.
Since I had both cars.. I can tell you the C32 with a smaller S/C pulley and intake was instant power delivery. Nothing like it.
My E55 has this gradual boost in comparison.
I would assume the throttle response of S/C pulley with the E55 will be much improved.
There is a limit on the E55 in terms of bearing size. So a mild boost S/C pulley and tune will not yield Crank pulley/Tune HP and TQ numbers. However it would be very simple to install and easy to remove.
Taking the pulley off will require an air impact gun. (Well my case with E55)
For the C32, it was much easier to remove.
Try to make the color match OEM. This will help just in case you take it to the dealer.
Can't wait for pricing. Sign me up for one.
Just like when I had the idler pulley`s made to replace the factory 400 dollar set; they are lighter, better bearings and save us all a ton of money!
The reason so many parts get made, is that no one will run 2-3 sets of anything!! The CNC has to be programed, drawings made and they laugh at you for a couple sets. Thats why when I want something for my car, I pay to have the the min. quanity run met. Lot business need the work, so it is a win, win for everyone.
I sent a lot of parts off all over the country in the last week , since I came back from SEMA but dont want to get kicked off the site, if I mention them all and hurt a vendors feelings..
I wish that all of us auto enthusiast could make what we want and talk about it but we saw what happened to Shardul. BTW, plan to have ultra high quality German bearings in this S/C pulley, so it can take all the extra high rpm !
