    Serious Converters for Serious Performance

    B&M Nitrous Holeshot Torque Converters are specially designed for use on Street Rods, Pro Street, and Street Machines with plate-type nitrous systems that produce serious horsepower, and need a torque converter that can handle it. B&M Nitrous Holeshot Torque Converters contain anti-balloon plates along with the same features as the other B&M Holeshots. The anti-balloon plates enable these torque converters to withstand the instant horsepower that nitrous delivers. Torque converters with higher than stock stall speed provide better acceleration from a dead stop and allow a vehicle with a big cam to idle better. The Holeshot can be used in a typical street machine, however when nitrous is used the Nitrous Holeshot is your best choice. The Nitrous Holeshot 2400 is the preferred choice for big cubic inch crate motor applications.
