- Hays Twister 3/4 Race Torque Converters
Hays Twister 3/4 Race Torque Converters are intended for street or strip use and work great in combination with Hays flexplates, clutches and flywheels. Each Twister is rated up to 650 horsepower and most applications are offered in multiple stall speeds to accommodate any combination of aftermarket upgrades. Almost all Hays converters are built to be application specific to reduce weight, increase horsepower and acceleration over multi-bolt pattern style converters. Each converter is hand-built and inspected to ensure the upmost quality.

A state of the art spray welding process is used in select areas and provides clean, strong and consistent fusion while also increasing strength through hardening from higher process temperatures. All Hays converters are internally welded compared to brazing, which provides a longer service life. Stators with high flow vents and channels are used to promote cooling and Heavy-duty Torrington bearings are used for greater strength and durability.
Hays recommends that all Twister Torque Converters are paired with an external transmission cooler (sold separately) that has at least 18,000 GVW or 15,000 BTU rating. The Twister 3/4 Race series is for street and/or strip use, but are not designed to be used with nitrous oxide or a trans-brake.
