Weistec Engineering, commonly known as Weistec, is an American high-performance aftermarket automotive engineering company founded in 2010 in Orange County, California, and is currently based in Anaheim, California. The company initially began developing performance parts for the Mercedes-AMG platform of vehicles and has since expanded into European and supercar performance tuning more broadly for brands like McLaren, Ferrari, Porsche, Audi, BMW, Alfa Romeo, Aston Martin, Maserati, Pagani, and Bentley. Weistec also develops off-road performance products through its Direct Current Engineering (DCE) subsidiary, and aftermarket accessories for Can-Am and Polaris, and for electric vehicles such as Rivian.

History

Weistec was founded by Michael Weiss, who began modifying cars as a teenager and later studied engineering at California State Polytechnic University, Pomona. Weiss worked as a development engineer at Saleen Automotive before starting Weistec. The company was originally based in Santa Ana, California, relocating to its current Anaheim facility in 2015.

In December 2010, Weistec released what it described as the first supercharger system built for the Mercedes-AMG M156 V8 engine, fitted to a Mercedes-Benz C63 AMG. The company subsequently introduced Stage 2 and Stage 3 supercharger packages for the same platform.

In October 2011, the California Air Resources Board issued Executive Order D-691, exempting Weistec's M156 supercharger system from the state's anti-tampering prohibitions for specified vehicle applications. The order was superseded in June 2017 by Executive Order D-691-2, which extended the exemption to specified M156 and M159 applications and cited independent laboratory emissions and onboard-diagnostics testing showing the system did not cause the test vehicle to exceed applicable emissions standards or interfere with OBD II monitoring.

In 2012, Weistec introduced the SLS 750 supercharger system for the Mercedes-Benz SLS AMG, combining a 2.3-liter twin-screw supercharger, an intercooler, a fuel-delivery system, and supporting components. Carbuzz reported the system produced 750 horsepower and 664 lb-ft of torque, describing it as the most powerful SLS AMG available at the time.

Since then, the company has broadened beyond its original Mercedes-AMG focus to work more on European and supercar performance platforms. Weistec has also moved into the off-road market, developing performance products for vehicles such as the Can-Am Maverick and Polaris RZR.

In 2013, autoevolution covered a Weistec-tuned Mercedes-Benz E55 AMG producing 578 rear-wheel horsepower, describing Weistec as "one of the most prodigious US tuning companies specialized in Mercedes-Benz." In a September 2019 interview on The HP Lyf Podcast, Weiss described the company's origins as starting with a product he built in his own kitchen. Weiss also appeared on former NBA center Jim McIlvaine's lifestyle and automotive podcast Marq'd Men (Episode 52, March 10, 2020) to discuss automotive performance engineering.

Weiss also appeared, alongside professional racing driver Tanner Foust, in the "Southern California: Passion" episode of the Drive with Swizz Beatz docuseries, which aired November 16, 2023, showcasing a Weistec-modified McLaren 720S among the supercar platforms the company works on.

In September 2017, Weiss, at the age of 31, was named to SEMA News' "35 Under 35" list of young automotive-aftermarket industry leaders as President and CEO of Weistec Engineering. Street Muscle Mag profiled Weiss as part of the same honoree class.

Weiss brought a Weistec-modified, 825-horsepower Mercedes-Benz SLS AMG Black Series, built for IndyCar driver Graham Rahal, to an episode of the automotive web series Jay Leno's Garage, where Leno test-drove the car and described it as "tastefully modified," saying it "pulls very nicely." The appearance was covered by Motor Authority, Hagerty Media, and Carscoops, all of which named Weiss and Weistec as the builder.

A Weistec-modified 2008 Mercedes-Benz CLK63 AMG ran a quarter mile in 9.16 seconds at 150.03 mph at Byron Dragway in Illinois, which the company describes as a world record for the marque. In 2018, Weiss won the "European" category of JE Pistons' inaugural Masters of Motors competition at the SEMA show in Las Vegas, for a twin-turbocharged Mercedes-AMG V8, described by Weistec as built around a CLK63 AMG Black Series.

Weistec has also displayed a modified 1998 Mercedes-Benz Unimog U1550L, covered by MBWorld at the 2021 SEMA show and, according to Optima Batteries, at the 2021 Easter Jeep Safari in Moab, Utah, alongside a Can-Am X3 Maverick.

In 2022, Weistec launched Direct Current Engineering (DCE), an aftermarket brand producing components for the Rivian R1S and R1T. At the 2022 SEMA show, DCE and Optima Batteries debuted overland-equipped Rivian R1T and R1S builds featuring solar-powered charging trailers, covered by ArenaEV, alongside other partners including Turtleback Trailers, BFGoodrich, and Monroe Intelligent Suspensions.

Operations

Weistec is headquartered in Anaheim, California, where it manufactures and distributes its performance parts and accessories, and provides ECU calibration and tuning. Through DCE, the company also produces aftermarket components for electric vehicles.

Weistec's in-house manufacturing capabilities include a dedicated CNC machine facility with 5-axis and multi-axis machines, including the Haas ST-30 turning center, for high-volume production. The company also performs precision welding and fabrication in-house.

In 2022, the company brought sheet-metal fabrication in-house for the first time, investing in fiber-laser cutting and press-brake equipment. For reverse-engineering parts, Weistec uses FARO metrology equipment alongside a scan-to-CAD workflow built around a MicroScribe coordinate measuring machine and Point2CAD software, which Weiss described as cutting a supercharger inlet tube reverse-engineering project down to about 30 minutes.

Products

Product lines include the Stage 1, 2, and 3 supercharger systems for the M113K and M156 AMG engines; the W.4 turbocharger package for the M157 engine; ECU calibration services; performance products for off-road side-by-sides including the Polaris RZR; and, under the DCE brand, rock sliders and accessory port adapters for the Rivian R1S and R1T and portable power stations for EVs and RVs.

Records and awards

On August 7, 2020, at the Sandhills Open Road Challenge in Arnold, Nebraska, a Weistec-tuned Mercedes-Benz R63 AMG minivan was reported by Motor Trend as the world's fastest street-legal minivan, a run driven by professional racing driver Tanner Foust in partnership with Optima Batteries. The same event was covered by Motor1.com, The Shop Magazine, and The Drive.

Weiss has raced a Polaris RZR Pro R 4 fitted with Weistec-engineered components in the NORRA Mexican 1000 off-road rally. He competed in the Evolution Open UTV class in 2023 and finished sixth in the Evolution Pro 2000 UTV/Class 10 category (28th overall) in 2024.
