X8

Actual converter may vary, image for illustration purposes only.

In ProTorque’s product line, the X8 is the “little brother” to its record-setting U9 converters which have shown tremendous proficiency in classes such as Ultra Street lately. The X8 is geared towards a larger sportsman-style market, including NHRA classes such as Factory Stock Showdown, Stock, Super Stock, Comp Eliminator, Top Dragster, Top Sportsman, and more. Able to support over 2,000+ horsepower, the X8 is also perfectly suited for cars in the 600-horsepower range and everything in between.

DAVID BARTON CLINCHES 2022 CHAMPIONSHIP WITH X8 SERIES CONVERTER

In the fiercely competitive world of NHRA Factory Stock Showdown racing, renowned engine builder David Barton clinched his second consecutive championship with Saw Mill Auto Chevrolet COPO Camaro. An impressive feat to do once, let alone twice in a row, Barton trusts ProTorque torque converters in his racecars and works closely with ProTorque’s engineering team to put together championship-caliber converters. Throughout the 2022 season, Barton made five final-round appearances and captured three national event wins at the NHRA Thunder Valley Nationals, the prestigious U.S. Nationals in Indianapolis, and the NHRA Nationals in Pennsylvania.

High performance integral strengthening struts provide extra support in critical areas to prevent flexing or ballooning and are fully radiused to prevent stress risers.

1000-2000 HP
Built For: GM Powerglide, GM TH350, GM TH400

Torrington style bearings on all surfaces provides durability and longevity for the life of your converter.

Many options are available for tunability in specific combinations and conditions. Custom stator designs allow for infinite adjustability to fine tune power application.

Featuring furnace brazed and reinforced tig welding to handle maximum power.
