Hays Performance Drivetrain is proud to announce the addition of Twister 3/4 Race Performance Torque Converters. Torque converters are a perfect addition to our line of performance Flex-plates, Clutches, and Flywheels. The 3/4 Race converter is the first series we are bringing to market. This series of converters is intended for street/strip combinations, with various stall offerings to accommodate any mixture of modifications including higher compression ratios, aftermarket camshafts, aftermarket cylinder heads, lower gear ratios, and vehicle weight loss. The name "3/4 Race Converters" perfectly describes a converter suited for an application just shy of Full Race, which is a series we will offer in the near future.Hays 3/4 Race Converters!Good names never go away, and neither should good terms!

3/4 Race series converters are built, tested, and proven to support up to 650 HP.
State of the art Spray Welding process is used in select areas. Spray Welding provides clean, strong and consistent fusion while also increasing strength through hardening from higher process temperature
Each converter is hand-built and inspected in every step of assembly to ensure top of the line quality
All HAYS converters are internally welded compared to brazing. Testing has shown welding provides longer converter life while also enhancing consistency
Heavy duty Torrington bearings are used for greater strength and durability
Stators are chosen with high flow vents and channels to promote cooling in heat producing higher horsepower applications
Increased horsepower and acceleration due to a weight saving, one application design. Almost all HAYS converters are built for one application to reduce weight compared to a multi-bolt pattern converter.
3/4 Race series converters are offered in several different stall speeds for GM, Ford, and Chrysler transmissions
Industry leading Tech Support Team is available to provide assistance with stall speed selection

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.
