Brooke, you Texas boyz role hard 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.

+1 ... would be awesome with my 168 crank pulley --- will this change the clutch engagement pack too??? or just a new contact wheel?

Price !?!

You get the pulley, high speed bearings and plate assembly.



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 .

Very interesting, less rotational mass on the blower certainly could ease the engines job. Pulley sizes are getting a little carried away for crank size also, so something like this could help a lot to get the boost you want and be able to run a smaller crank pulley to also lower that rotational mass.

I would like to see the Bypass shut off and then block the hole(welded?) so boost cant push past the blade and then run a nice BOV on the surge tank.

I have the 180mm pulley already installed, would it be advisable to run this in addition or will the heat kill me?

Please put me on the list, I would love to get in on this, please pm pricing

I would guess this would be a good combo. Others will do this with larger pulleys. Depends what other mods you have, and how much boost you want. Based on Brookes estimate this would equate to 6mm - 8mm of Crank pully, so the combo you describe would = 186 - 188 (ish) But spin up would be faster due to rotational mass. I would say it is an A plus mod. With a 180, you should already be addressing heat (Pump / Aftermarket HE etc)

Well they did do ONE 55 sc pulley many years ago. Who who who ah ah ah ahhhhh!! I am so bad. Unfortunately like most my mods back then it was in a drunken stupor( modding being the booze) and I got no dynos blah blah blah. Sounds amazing what you are doing B!! I need to just switch my sig to "holy cow" with bowing for the weekly stuff going on here lately!!

i run the c3 s/c pulley (65mm) on my 3.2 and others with my platform have stacked pulleys also. rememebr the max rpm the s/c can spin at and avoid overspinning the s/c. for us a 67 mm s/c pulley and a 178 mm crank pulley puts the s/c at it max rpms. big power but dangerous if mistuned or overrevved

Guys great idea,the guys over in the middle east have done this also but when I asked they wanted 2k for the smaller pulley.

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.

skratch777,

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.

Thanks for the development.

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.

I know a couple of people have modified the stock 55 pulley but very small gains can be made there. This part is a complete new assembly, made in USA and every part of the assembly is new. Clutch plate, pulley, bearings, rivots, springs and clutch/pulley spacers. A new assembly from MB is around 1K!!!!

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 !
