Powerglide, Turbo 350, Turbo 400, “Super 8″, 9” 4000-6500RPM Stall Torque Converter
As the innovators of the spragless converter, Transmission Specialties is renowned worldwide for the highest quality racing torque converters. As the innovators for the industry, we know what works and what doesn’t. There are no smoke and mirrors here, just the highest quality racing converters built from the best materials money can buy. TSI is the world’s largest supplier of racing torque converters components. Nearly every other converter company in the world uses our components in their builds. We are happy to present one of our most popular converters we sell.
The TSI Super 8 9” Billet Torque Converter is the perfect converter for the racer with 800-1200HP. This converter uses all NEW internal components, NO reclaimed parts are used in the building of these converters. Only the highest quality billet front covers, furnace brazed pumps and turbines are used. Our stator designs are revolutionary and will give you lightning-fast launches while still coupling hard on the top end.
A few notes about the sprag options you can choose from. Customers that want the most consistent ET will want to select the Spragless Option. By selecting the Spragless option you eliminate the one-way clutch in the stator. The one-way clutch is not only a failure point but it leads to inconsistency due to slippage. The only negative of the Spragless design is the inability for the stator to freewheel. This lack of freewheel will slightly lower the ET and MPH versus a mechanical diode or sprag setup. The mechanical diode option is available for those racers who want to shave the last little bit of ET off and increase MPH. By selecting this option, you will now have a stator that is allowed to free wheel after reaching its stall speed. This free wheel action allows the oil to flow smoothly from the turbine to the impeller. This smooth oil flow allows better coupling which results in improved ET and MPH. The mechanical diodes we use at TSI are the strongest in the industry and have been tested for over a decade in the most demanding applications!
