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.
World Record CLK 63 AMG Black Series Built by Weistec
We can our Mercedes Benz AMG CLK 63 Black Series to Atco Raceway in New Jersey and set the world record for the fastest Mercedes. We finished
with 9.75 secs at 151.95 MPH. 60-130 MPH in 4.32 secs!
Before and After 1/4 Mile /// -2 Seconds, +15 MPH
David Dimitrion built C63 with Weistec Supercharger. 1/4 mile testing of Mercedes Benz C63 Coupe before and after the installation of a
Weistec 3.0 L Supercharger by David Dimitrion. As you will see in the video, the results are impressive. The Weistec Supercharger knock 2
seconds off the C63's 1/4 mile time (12.5 to 10.5 sec) and picked up 15 mph (112 to 127 mph).
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 our
trunk 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 an Authorized Dealer,
by mail, or remotely using the Cypher Handheld Programmer (Not included). For more information
check out our How 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.
