    B&M Holeshot Torque Converter are designed with a higher-than-stock stall speed that is beneficial to vehicles with modified engines. Big cam modifications, for example, tend to reduce low end power and torque so using a high-stall converter allows an engine to launch a car at a higher RPM where more torque is available. B&M Holeshot Converters feature a furnace-brazed impeller and turbine, new turbine hub, new alloy steel pump drive tube, new heavy-duty needle bearing between stator and turbine (not a thrust washer), new springs and rollers in stator, and dual pattern drive lugs on some GM torque converters. Holeshots, which are also available in a Nitrous Series, are generally good for street machines that crave better launch capability and more tractability and street rods with modified engines. They are not for transbrake applications.

    RPM ranges for B&M Holeshot Torque Converters:
  • Holeshot 2000: 1900-2100 RPM
  • Holeshot 2400: 2300-2500 RPM
  • Holeshot 3000: 2800-3200 RPM
  • Holeshot 3600: 3400-3800 RPM

    Stall Speed Very mild street cars use a 2000 RPM stall speed unit. Most street-driven performance cars with 350 foot pounds of torque or more need a 2400 RPM unit. Cars with more radical small blocks (500 foot pounds of torque at 4500 RPM or higher) require a 3000 RPM converter. The more torque a motor puts out, the higher the resulting stall speed. Therefore most street performance big blocks would still use a 2400 RPM converter because they generally achieve 2600-2800 RPM. An engine smaller than 350ci might not achieve such stall speeds, which are based on an engine producing 230 foot pounds of torque at 2500 RPM.

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

  • Does this fit your vehicle?
