Weistec POWER PACKAGES

Weistec power packages are an efficient and effective solution for those looking for improved power output and performance. With various combinations of ECU Upgrades, High Flow Air Filters, ROW Airboxes, Racing Sparkplugs, True Downpipes, VTA Adapter Systems and more, the resultant tailor engineered packages can give your Mercedes well balanced, increased horsepower and torque, improved throttle response, an eliminated top speed limiter, improved airflow, and a free flowing exhaust with an aggressive note. Weistec offers packages ranging from basic power extraction to advanced motor transformation, with packages W.1, W.2, and W.3.

Weistec SUPERCHARGER AND TURBO SYSTEMS

Weistec engineered supercharger systems for your Mercedes CLK 63, SLS 750, and SLS 825 will bring your car to the pinnacle of speed and performance with 637 (560 ft-lb torque), 750 (654 ft-lb torque), and 825 (661 ft-lb torque) horses respectively. Numerous Weistec engineered turbo upgrades, advanced belt and pulley systems, heat shields, anti surge valves, and stages of upgrades for your preexisting turbo or supercharger have been created to meet your power extraction needs.

Weistec UPGRADED SUSPENSION

Weistec adjustable billet aluminum coilovers for your AMG GT / GTS or SLS and Adjustable Suspension System for the W205 C63 and C63-S allow for a wide range of adjustment in ride height, while still being able to maintain proper alignment without the need for special parts or tools. Perfected spring rates were determined after extensive street and track testing as well as vehicle weight measurement and balancing. The result is noticeably sharper and more responsive handling characteristics without compromising every day driveability.

Weistec M157 W.4 PACKAGE

The M157 W.4 Power package for the CLS63, E63, G63, ML63, S/CL63, S63, and SL63 is the world's leading Mercedes performance upgrade package. At the core of the M157 W.4 Package is the M157 W.4 Turbo Upgrade. Taking a giant leap ahead of all other available upgrades, the M157 W.4 Turbochargers completely replace the factory units. They are ball bearing, featuring CNC machined billet aluminum compressor wheels capable of flowing 65lb/min. New airboxes and intake tubes are needed to fuel the massive turbo. The Weistec Turbo-Folds provide significantly increased flow of exhaust gasses. The Weistec M157 True Downpipes perfectly mate up to the M157 W.4 Turbochargers to ensure minimal restriction once the exhaust gasses have gone through the turbine. The resulting 1000+ crank horsepower is made possible at 20 psi of boost, without an iced down inter cooler system, and while using basic 91 octane gas.
