COMPARE SUPERCHARGER STAGES

**Price may vary by vehicle model.

The Weistec Stage 3 Supercharger System was designed and introduced to meet the needs of customers that kept asking us for more power even after installing our Stage 2 system. Incorporating many years of Mercedes supercharger knowledge, the larger 3.0L twin-screw is the pinnacle of Weistec’s supercharger systems. Many people now go straight to Stage 3 from stock, but those that already have a Stage 1 or a Stage 2 supercharger can get our Stage 3 upgrade system to convert to Stage 3

Using our 3.0L Twin Screw, we have set the record for the World’s Fastest Mercedes with our Stage 3 M156 System and supporting Weistec products, generating engine power levels exceeding 1000 Horsepower.

8-RIB PULLEY SYSTEM

Our Stage 3 Supercharger runs an 8-Rib pulley system. The larger supercharger unit takes more effort to spin up to speed. The standard 6-rib belt drives on a stock M156 engine and on the Stage 1 and Stage 2 superchargers are simply not up to the task of spinning the 3.0 supercharger unit up for high power levels. With our included 8-rib conversion, the entire belt drive is upgraded to switch to an 8-rib belt which offers a substantial increase in belt gripping surface.

HEAT MANAGEMENT INCLUDED

The Stage 3 Supercharger System features a liquid-to-air intercooler core rated to 1000hp, a Johnson CM30 30 liter per min intercooler water pump, Cross flow heat exchanger, and an intercooler water recovery tank. For those looking for more cooling, we offer ourtrunk ice tank (not included) which substantially increases liquid volume and allows for icing of the intercooler system when drag racing

TUNE INCLUDED

Every supercharger comes with a tune. Our calibration team prepares a tune for your vehicle and all the mods that your build is running. You can receive your tune in person, at anAuthorized Dealer, by mail, or remotely using theCypher Handheld Programmer(Not included). For more information check out ourHow to Tune Page.

IMPROVED FUELING

While the Stage 1 and Stage 2 systems make power levels that are within the capability of the factory fuel injectors, Stage 3 goes well beyond those limits. This is why we include a set of matched and custom spec 650cc injectors along with the 8an billet fuel rail setup that is included with all of our supercharger systems.
