Hays Twister Full Race Torque Converters

By: Ray Frescas | 01/22/2019 < Back to Motor Life Home

Hays Twister Full Race Torque Convertors are designed for quick, hard launches and give you time killing ET’s! The main feature of our Full Race series is the installation of a custom anti-balloon plate, designed to stop torque convertor ballooning. These converters will support up to 1000 horsepower. If you’re using a Trans-brake, nitrous, supercharger or turbos, these torque convertors have your name on them.

Built in the USA, each torque converter is hand-built and inspected at every step of the assembly process. All Hays torque converters are internally welded, not brazed, to ensure long convertor life launch after launch. They are built, tested and proven utilizing a state of the art “spray welding” process to provide strong, consistent welds to the hub assembly so it can handle the extreme environments of racing. Torrington bearings are used for strength and durability while stators incorporate high flow vents and channels to further promote cooling. Turbine fins are internally welded to provide longer converter life while also enhancing consistency versus standard brazed fins. Hays Full Race torque converters are offered in several different stall speeds for popular GM, Ford and Chrysler transmissions. Hays Full race torque converters are designed to handle the extreme shock and abuse of trans-brakes, nitrous oxide, superchargers, and turbochargers.

Selecting the correct stall depends on your race engine and vehicle combination. Make sure to select the correct stall for maximum performance. We have videos and also offer an online Torque Converter Selector sheet for you to complete or any of our Tech Support team can help you with stall speed selection to accommodate any mixture of modifications you have added such as camshaft, lower rear gear ratio, cylinder heads, or power adder .

Get quick and consistent launches with a Hays Twister Full Race Torque convertor!
