Hays Performance Drivetrain is proud to announce Twister 3/4 Race Performance Torque Converters. These NEW torque converters are a perfect addition to Hays product line of performance flexplates, clutches, and flywheels. The 3/4 Race torque converter is the first series being brought to market and is intended for street/strip combinations, with various RPM 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.
- All Full Race series converters are built, tested, and proven to support up to 1,000 horsepower
- Full Race series torque converters are offered in several different stall speeds for popular automatic transmissions
- Stators are chosen with high flow vents and channels to promote cooling in heat producing higher horsepower applications
- Heavy duty Torrington bearings are used for greater strength and durability
- 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.
- Each converter is hand-built and inspected in every step of assembly to ensure top of the line quality
- Industry leading Tech Support Team is available to provide assistance with stall speed selection
- Designed to handle the extreme shock and abuse of trans-brakes, nitrous oxide, superchargers, and turbochargers
- All Hays torque converters are internally welded compared to brazing. Testing has shown welding provides longer converter life while also enhancing consistency
- Features a custom anti-balloon plate designed to stop potential torque converter ballooning
- 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
