Weistec Engineering M113K Modular Supercharger Pulley
We are pleased to announce another Weistec exclusive with our new Fluid Dampened Modular Supercharger Pulley for your M113K Powered AMG!
Key features include:
The optional crank pulley pinning tool is highly recommended for those who plan on making high power and spinning the supercharger systems at high RPM's. It is very common to damage the factory keyway, causing crank snout issues. This is a simple precaution for long term longevity of engine parts.
The Weistec Fluid Dampened Modular Crank Pulley is Priced at $1,249.99
Detailed product and purchase information can be found at our website.

Key features include:
- 3% Under-driven 6-rib fluid dampened crank pulley
- Internal high mass rotating inertia ring for proper dampening and harmonics
- 4lb drop in total weight as compared to the stock crank pulley assembly (10.5lbs vs. 6.5 lbs.)
- Simple 10 minute supercharger drive pulley swap via three bolt dowel pin design
- Multiple supercharger pulley combinations to choose from - 150mm (stock), 170mm and 180mm
- Hard anodized 6061 heat treated aluminum for the strongest durability and appearance
- Tool steel crank pulley hub with woodruff key and Weistec exclusive key provisions for use with our optional pinning tool
- OEM crank pulley bolt included
- 17% overdriven water pump pulley for clearance of larger supercharger pulley rings
- Includes proper sized 8-rib Gates HD belt based on your needs

Same nightmare that is running on our M156 supercharger for the past 4 years with no problems and has set multiple world records. We will let those who run our Stage 3 M156 Systems chime in.
And just to correct you even more, this is internal Version 24.0, and the public's only version. We actually test what we sell.

A majority of its torsional force is on the 3/8" pins, its kept perfectly centered via hub-centric machining, and clamping force is on the three bolts bolts.
Hope this explains it a bit more in detail. Thanks!

Looks badass. I might have to add this to the list even though I don't plan on going higher than stock size. What I quoted is the critical part. Other companies make the consumer the guinea pig. I'm glad at least someone is testing their product before selling to the public. I've seen way too many failures from shady companies. Then they change their company name and sell another product. An dusually the company isn't even in their name! You know who you are

The universal problem in the past has been, no warranty coverage on damaged crankshaft caused by pulley failure. So a tested pulley should have a warranty that covers all damage caused by a pulley failure, right?
Back in the day a new crank installed was north of $18k today maybe half that.
How many pullies have been made for the E55 now? A, E, R, V, S, and now W.

Other designs put all the load of both belts on the crank hub. Technically speaking, all the energy is absorbed by our hub as well but the crank pulley is mounted completely separate from the hub which alleviates this issue. This part of it has been ran on our M156 pulley for the past few years with absolutely no issues. Hope this helps.
Our pulley is the best solution for those seeking more power because the provision of adding extra key ways is made very simple and implemented in this part. High RPM, hard fast shifts, etc. will tear apart the single woodruff key. We would hate to see any of you deal with this because it typically requires a complete overhaul of the engine and possibly a new crankshaft. Let us learn the hard way and offer the solution!

The issue mentioned previously (and a valid concern) is the supercharger ring breaking off. Since the ring is separate from the crank pulley, this is a completely different issue.

That is a very nice looking piece.
I would like to know more about the fluid dampening part and how that works.
Is the outer belt drive ring on the normal belt drive connected directly to the hub, if not how is it driven?
The supercharger drive ring, is that connected directly to the hub or the other belt drive ring?
How does the fluid work and what is absorbing the torsional vibration?
Want to make it clear that I am not trying to be a jerk here, I am generally interested in how this works. Looks like you put some real thought into this.

That looks really really good, like it was designed to be the best so that no one can top it.
I like that mind set.
Any idea on life expectancy?

Weistec,
Very nice...thanks for supporting the E55.
Would love to see you produce a kit that includes an upper pulley that ditches the clutch...fully sorted and complete with tune.

Both the crank pulley (fluid dampened 6-rib pulley) and the supercharger ring are mounted through to the steel hub. They are however mounted separately which means you are not putting all the load of both belts and all harmonics through the same bolts that hold both assemblies together. Mounting hardware is separate for the crank pulley and supercharger ring. Let us know if this helps. Thanks!

The actual fluid dampening portion of it that takes far more engineering that keeping a pulley in tact has been ran on our M156 supercharger system for many years now with no failures at all.

I can see I will have to order two of them. One to take apart so I can understand what is going on inside of there and one to put on the car.
I remember that digital watch I got long time ago. Did not last an hour....
