Chrysler TF-904
Installation Notes:
- Warning: The "3/4 RACE" Twister series converters are NOT designed to be used with Nitrous Oxide or Trans-Brakes
- 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 below for more info)
** ADVERTISED stall speeds are based off of a 3600 lb. car with 200 HP/275 ft.-lbs., 3.42 gear, and a 26 inch tire.**
With this in mind, to achieve a DESIRED or ACTUAL stall speed for your application, it may require a converter with a substantially different ADVERTISED stall speed.
Example: A Street Rod that weighs 2,000 lbs. with a DESIRED stall speed of 1800 RPM. The lighter weight of the vehicle reduces the stall of the torque converter. To achieve a DESIRED stall of 1800 RPM, you would need a converter with an ADVERTISED stall speed of 4200-5000 RPM.
- Weight: Like the example shows, a vehicle lighter than 3600lbs. will reduce the stall of a converter. A vehicle heavier than 3600 lbs. will increase the stall of a converter.
- HP/Torque: A vehicle with an engine producing more than 200HP/275 ft.-lbs. will increase the stall of a converter. A vehicle with an engine producing less than 200HP/275 ft.-lbs. will decrease the stall of a converter.
- Gear: A vehicle with a numerically higher (lower) rear gear will reduce the stall of a converter. A vehicle with a numerically lower (higher) rear gear will increase the stall of a converter.
- Tire Size: A vehicle with a tire shorter than 26” will raise (numerically) final drive gear ratio, and reduce the stall of a converter. A vehicle with a tire taller than 26” will lower (numerically) the final drive ratio, and increase the stall of a converter.
- Exhaust: Open headers will decrease the stall RPM of a converter when compared to a full exhaust system on the same vehicle.

Motor Vehicles
WARNING: Motor vehicles contain fuel, oils and fluids, battery posts, terminals and related accessories which contain lead and lead compounds and other chemicals known to the State of California to cause cancer, birth defects and other reproductive harm. These chemicals are found in vehicles, vehicle parts and accessories, both new and as replacements. When being serviced, these vehicles generate used oil, waste fluids, grease, fumes and particulates, all known to the State of California to cause cancer, birth defects, and reproductive harm.
Tools:
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically treated lumber. Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
