Hays Twister 3/4 Race Torque Converters--Good names never go away, and neither should good terms!
Hays Twister 3/4 Race Torque Converters--Good names never go away, and neither should good terms!
- 3/4 Race series torque converters are built, tested, and proven to support up to 650 horsepower.
- 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 torque 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 torque 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
Information:
Warning: The 3/4 RACE series converters are NOT designed to be used with Nitrous Oxide or Trans-Brakes Note: HAYS recommends an external transmission cooler for all Twister 3/4 Race Converters (A minimum size of 18,000 GVW or 15,000 BTU Rating.) Note: Stall ranges will vary depending on engine set-up, weight of vehicle, and gear ratio (Please see converter selector in tech resources for more info)Application Summary:
