M113K Upper Fixed / Clutchless S/C Pulley
With all the Biturbo, single Turbo, built blocks, after market blower threads etc etc project going on. We figured we would work on something too and offer it to the MB community.
-Ultra lightweight and removes over 3 lbs of rotating mass from the SC , that turns at almost twice as fast as the crank pulley.
-Super quick spool up time to max boost levels.
-Fixed SC pulley sizes range from 168mm to 200mm crank pulley equivalent, and all from an easy SC pulley change.
-Low inertia fixed pulley, frees up lost power, while not adding heat from extra boost needed to turn heavier parts
-Quicker response time going into wide open throttle
-Install is easy and does not require removal of super charger or permenant modification of sc shaft
-The pulley is held on by interference fit, factory bolt and factory roll pin design. You just align the part like the fatory unit and just torque onto the shaft. Very easy and no shims needed.
-pulley will work without the magnet on the SC shaft
-This unit will be 100% compatible with the belt wrap kit.
-Pulley will be avaliable for sale within the next 20 days.
-Pricing will be relased soon.

Interesting. Does mean the SC is always engaged since there is no clutch? How is the driveability?

Will be curious when it's released.. Decisions decisions..

Highly interesting for sure. But for a daily driver im not sure. Fuel consumption will significantly rise.
I remember AMGs claim that our compressor eats around +-100HP at max-RPM alone to spin.
Dunno how that is at lower RPM though, but i guess a clutch is there for a reason.
Hopefully the guys from Eurocharged can chime in here and talk a bit what their findings are.

wow this is very exciting, im interested in how exaclty this will affect the fuel mileage tho? i dont doubt that it would change but what will "make" it lose fuel economy????
losing that magnet should make a huge difference!!!

The power needed to actually move the Kompressor.
Like stated before, AMG once said its 100HP of crank power wasted for propulsion of the Kompressor at max-RPM (~6200RPM).
Thats why there was/is a clutch for normal driving.

Right... currently the supercharger engages via throttle response / RPM based on your driving habits. That's why the highway MPG of this car can be good if you're cruising around 70-80 as the supercharger can remain off.

Subscribed for this. I think it is a great idea as long as the mapping makes it driveable. As far as MPG goes, as long as I can make it from gas station to gas station it's all good.

Not knocking it but there's no "spool-up". Its crank driven not pressure driven like a turbo. Either way its good to see people still trying to come up with new things for these cars. Hope the correct R&D is done. Whats the weight difference between this and your smaller s/c pulley?

Just cruising at part throttle will take a fraction of that number to turn the supercharger, as in less than 10hp with the bypass valve open. The only losses are the power needed to spin the aluminum rotors themselves since the system is under no pressure.
It takes a lot of power to turn at RPM because it's a positive displacement blower compressing air into a plenum already under pressure.

As far as MPG's the weistec is clutchless and didn't lose MPG's. I'm sure your right foot will have a bigger affect than the clutchless SC. I rarely take mine on long trips so eff mpgs.

If there is no big change (within 10% range after a good tune) for casual driving, i wait and rather buy this instead of the smaller SC pulley with clutch.

Fixed SC, is about 2 lbs lighter than the smaller Sc pulley we have out.
With a much lighter clutchless pulley, no clutch to slip, reduced engine inertia on the crank and rotaing assembly; engine will rev quicker and allow the SC to spin up or reach desired RPM quicker. The Sc spins about 2 times to each turn of the crank (depending on crank size), so this is a good place to take off weight as well.

Brooke,
What's it take to take the magnet off the SC? Probably what 2-4lbs savings there as well?

It takes a puller to remove it. Of course MB has a tool for it but $$$$.

thats right, when its pulling vacuum its much easier to spin. once it starts getting under pressure is when the hp comes in but that would be the same with clutch or not. a for instance the tvs1900 which is the latest generation eaton with 4 lobe hybrid roots only takes 2 hp to drive with bypass open going down the road.
