Introducing the Weistec Engineering Torque Converter

Weistec Engineering is excited to introduce the first and only upgraded torque converter designed specifically for the AMG 722.9 transmission, which powers a variety of AMG models. This innovative lock-up style converter has been completely reimagined by our talented engineers, featuring a 2500 RPM stall speed. What does this mean for you? Enhanced take-off and low-speed acceleration, leading to improved performance whether you're cruising around town or tearing up the track, all while keeping that factory drivability you love.

Precision Engineering for Maximum Performance

The 722.9 Torque Converter is crafted with precision in mind. Each unit is computer-designed and manufactured using machined billet internals, ensuring top-notch quality and consistency. The result? An upgrade that boosts the performance of every vehicle, from your everyday driver to those high-powered race cars exceeding 1000HP.

Proven Results

In our extensive testing, we found that average 60-foot acceleration times improved by as much as two-tenths of a second. It's a well-known fact in the automotive world that any enhancement in 60-foot times can lead to even bigger gains in quarter-mile performance. For the best results, pair the Weistec Torque Converter with our ECU tuning software. And rest assured, it’s fully compatible with factory electronics.

What Is Weistec Engineering?

Based out of Orange County, California, Weistec Engineering is an industry leader in research, development, and design. While the company was only established in late 2010, founder Michael Weiss and his partner Steve Atneyel both have an impressive track record of working with some of the fastest and most powerful vehicles in the world. The duo were both engineers for major American OEM and aftermarket performance companies; Michael was involved with advanced engineering, while Steve specialized in computer calibration.

Michael Weiss and Steve Atneyel decided to branch out on their own and combine their expertise and experience. The pair were, and still remain, avid Mercedes enthusiast and realized that there was a huge gap in the market for a company dedicated to engineering state-of-the-art performance systems for cars powered by motors like the M156 and M159 AMG.
