[More Info]
Hays Twister 3/4 Race performance torque converters are a perfect addition to our line of performance flexplates, clutches, and flywheels. Our 3/4 Race series of torque converters is intended for street/strip combinations, with various stall speed offerings to accommodate any mixture of modifications including higher compression ratios, aftermarket camshafts, aftermarket cylinder heads, lower gear ratios, and vehicle weight loss. The Twister 3/4 Race torque converter perfectly describes a converter suited for an application just shy of Full Race converter. Hays Twister 3/4 Race Torque Converters--Good names never go away, and neither should good terms!
Features:
  • 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
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)
