    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.

    RPM Ranges for B&M Nitrous Holeshot Torque Converters:
  • Nitrous Holeshot 2400: 2300-2500 RPM
  • Nitrous Holeshot 3000: 2800-3200 RPM
  • Nitrous Holeshot 3600: 3400-3800 RPM

    Features:
  • Furnace brazed impeller
  • New precision steel alloy pump drive tube
  • New heavy duty needle bearing between stator & impeller (not a thrust washer)
  • Needle bearing between stator & turbine
  • Furnace brazed turbine
  • Dual pattern drive lugs on some GM Holeshots
  • New turbine hub
  • New springs & rollers in stator
  • Anti-balloon plate

  • Does this fit your vehicle?
