    Weistec updates M156 supercharger offering to Stage 1, Stage 2, Stage 3, and 50 State Legal setups with price drops

    The Weistec M156 Stage I, Stage II, Stage III, and 50 State legal CARB certified supercharger offering for the naturally aspirated 63 AMG motors has been updated along with price drops. Weistec officially announces the Stage 3 system as well which includes the updated 3.0 liter twin screw blower. The Stage III setup is capable of 1000 horsepower but of course without a built motor including forged pistons and rods the motor will not reach this output.

    Stage I

    Let's start with the Stage I whose price is now $12,999.99 and rated at 534 wheel horsepower and 560 pound-feet of wheel torque:

    Key Features:


    • 2.3L Twin-Screw Compressor Module Why Twin-Screw?
    • 1000hp Liquid to Air Intercooler Core
    • High Flow Cast Aluminum T6 Hardened Lower Manifold
    • High Flow Cast Aluminum T6 Hardened Throttle Body Inlet Y
    • 45mm Boost Bypass Assembly
    • Billet Aluminum Direct Drive Cradle System
    • Supercharger Serpentine Drive Belt
    • Hard Anodized Billet Aluminum Serpentine Idlers
    • Johnson CM30 30 Liter/Min Intercooler Water Pump
    • Intercooler Water Recovery Tank
    • Cross Flow Heat Exchanger
    • High Flow Fuel Rail System
    • Molded Silicone Couplers
    • Power-Steering Reservoir Relocation Assembly
    • Weistec Engineering Stage 1 Supercharger System ECU Reflash

    Stage II

    If the Stage I is not enough power (and when is it ever enough power?) the Stage II is available for the same price of $12,999.99 which should make it fairly easy for one to choose this Stage for a bit more power and torque over the Stage I:

    Key Features:


    • 2.3L Twin-Screw Compressor Module Why Twin-Screw?
    • 1000hp Liquid to Air Intercooler Core
    • High Flow Cast Aluminum T6 Hardened Lower Manifold
    • High Flow Cast Aluminum T6 Hardened Throttle Body Inlet Y
    • 45mm Boost Bypass Assembly
    • Billet Aluminum Direct Drive Cradle System
    • Supercharger Serpentine Drive Belt
    • Hard Anodized Billet Aluminum Serpentine Idlers
    • Johnson CM30 30 Liter/Min Intercooler Water Pump
    • Intercooler Water Recovery Tank
    • Cross Flow Heat Exchanger
    • High Flow Fuel Rail System
    • Molded Silicone Couplers
    • Power-Steering Reservoir Relocation Assembly
    • Weistec Engineering Stage 2 Supercharger System ECU Reflash

    Stage III

    Here is the big boy Stage III featuring the 3.0 liter twin screw upgrade from the 2.3 liter. Power output on stock internals for this stage is 630 wheel horsepower. This is good for just under a 100 wheel horsepower gain on top of the Stage II. And at a price of $15,780.99 it is difficult to not encourage someone in the market to pay the difference and step up to the largest power offering possible on the stock internals with room to grow with built internals should one desire it. And with there never being enough horsepower this is definitely a smart way to go with future growth in mind.

    Key Features:


    • 3.0L Twin-Screw Compressor Module Why Twin-Screw?
    • 1000hp Liquid to Air Intercooler Core
    • High Flow Cast Aluminum T6 Hardened Lower Manifold
    • High Flow Cast Aluminum T6 Hardened Throttle Body Inlet Y
    • 45mm Boost Bypass Assembly
    • 8-Rib Direct Drive Belt System
    • SFI Approved Light Weight 8-Rib Crank Damper
    • Crank Pin Drill Tool
    • Billet Aluminum Direct Drive Cradle System
    • Hard Anodized Billet Aluminum Serpentine Idlers
    • Johnson CM30 30 Liter/Min Intercooler Water Pump
    • Intercooler Water Recovery Tank
    • Cross Flow Heat Exchanger
    • High Flow Fuel Rail System
    • High Capacity Fuel Injectors
    • Molded Silicone Couplers
    • Power-Steering Reservoir Relocation Assembly
    • Weistec Engineering Stage 3 Supercharger System ECU Reflash

    50 State CARB Legal:

    If one is concerned about emissions and the environment (the responsible AMG owner) there is also the 50 State Legal system which is CARB certified. It does offer the least amount of power but is safe for the environment and compliant with emissions laws which certainly is important. This setup will provide "only" 501 wheel horsepower which certainly is more than enough for the vast majority of 63 AMG owners who wish to simply supercharge and not have to worry about emissions legality or testing. Pricing is $13,499.99.

    Key Features:


    • 2.3L Twin-Screw Compressor Module Why Twin-Screw?
    • 1000hp Liquid to Air Intercooler Core
    • High Flow Cast Aluminum T6 Hardened Lower Manifold
    • High Flow Cast Aluminum T6 Hardened Throttle Body Inlet Y
    • 45mm Boost Bypass Assembly
    • Constant Mu, Delta Pressure (CMDP) Cog Drive System
    • Billet Aluminum Cog Drive Cradle Assembly
    • Poly Chain GT Carbon Fiber Cog Belt
    • Supercharger Serpentine Drive Belt
    • Hard Anodized Billet Aluminum Serpentine Idlers
    • Johnson CM30 30 Liter/Min Intercooler Water Pump
    • Intercooler Water Recovery Tank
    • Cross Flow Heat Exchanger
    • High Flow Fuel Rail System
    • Molded Silicone Couplers

    Quick overview of all the Weistec M156 supercharger systems:

    Click here to enlarge

    By dropping prices and expanding the product offering Weistec proves it is well aware of the economic climate remaining very competitive and assertive offering multiple packages depending on customer desire and needs. Weistec is able to cater to any M156 owner and the dollar per horsepower ratio here is hard to argue against and naturally aspirated M156 motors simply will not be able to match the power, torque, and potential of these supercharger setups. Congratulations to Weistec for adjusting to the market and continuing to raise the bar.

    Yes those are stock engine numbers. Obviously higher output with a built motor.

    How much boost with the 3.0 liter? We need @Weistec to answer that.

    I might be jumping the gun on this but from the pulleys I am getting must be 11psi.

    Gentlemen, we are very excited to release our new packages and allow current and future customers to enjoy even more power if the wish with our new Stage 3 Supercharger System.

    George that is correct. It is 11psi of boost with the 3.0L. It puts the new 3.0L right in its sweet spot in terms of efficiency and power output. We do recommend our Bullet Proof Transmission upgrade for increased longevity, but the is up to the customer.

    The new 3.0L system when turned up can make past 800hp at the wheels (837whp to be exact) and this is at 18 psi of boost. Of course this can only be done with our forged internals and fuel system. Let us know how we can assist!

    Congratulations guys, well done and the price drop is of course nice to see.

    So 837 wheel with the fuel system and built motor, a gain of about 200 whp at the same compression with another 7 psi, correct?

    To be fair, the 837 hp at the wheels was done with 18psi, MS109 race gas and a tune specifically designed around this, but yes that is correct. The M156 is a great engine that has flow characteristics that are truly unmatched.

    Thank you.

    The blower is not maxed in any package even with the built internals, correct?

    Joe - we will let you know when the next round of stuff is done. To answer your next question, we are not disclosing anything at this stage (gotta keep some things private right?).

    Actually in fairness at this point it is not about power, it is making the power work. You can have 2,000+ at the wheels but if you can't get it to the ground, it is meaningless.

    The roadblock is time. Even if I wanted to wash the car I couldn't do it.

    Back and forth between Florida, Toronto, and Rome at the moment which will continue until the end of Oct.

    I see but the car itself is working just a matter of having the time to use the vehicle it seems.

    I will hopefully be able to give you guys first hand experience by the second week of October. Traction will be a hurdle as the wide body is only getting done in December.

    Well saying it won't max the 2.3 liter may not be accurate.

    The M156 is a very efficient motor and the heads move a good amount of air. A motor with high volumetric efficiency to begin with will max smaller blowers pretty quickly. As you can see by going from the 2.3 liter to the 3.0 even on the stock internals provides a large horsepower and torque gain.

    Also, the larger blower will likely be able to move more air on pump gas before detonation. When you compress air you heat it so the smaller blower would have to work harder and essentially be spun faster to keep up possibly being moved out of its best range of efficiency. Also probably needing higher octane fuel as well. The 3.0 also gives you much more head room.

    @Weistec can answer this question better

    I think what he is trying to say is you need built internals to max the 2.3 liter which does not appear to be accurate. You pushed it fairly far with race gas. The 2.3 obviously won't support the hp you are now making with the 3.0.

    Bilal, what specifically are you asking? As far as the SC goes, depending upon the HP levels you desire, the 2.3 is maxed out and you need to move to a larger setup.

    We are happy to answer any questions you may have. Our Stage 2 system which utilizes the 2.3L compressor is right in its efficiency range at that power level (about 670-675HP at the crank) when installed on an M156 engine. In testing we have made much more than this with the 2.3L (closer to 800HP at the crank on even a stock engine) but we were completely out of the compressors efficiency and reliability would go downhill if we were to sell that. In essence, we maxed The 2.3L compressor out. Instead we designed the new 3.0L Stage 3 system which easily makes the same power, but with much cooler air charge temperatures, less boost, and much less struggle. Please let us know how we can assist.

    Do you have plans for centrifugal blowers? Not much extra torque so transmission will be in a better shape, and up top you get much more horse power to kick some butt Click here to enlarge

    OT and a noob question. Is there any stroker kit available for M156?
