B & M – Holeshot 2400 (Part No.70419)

Holeshot 2400

from

$670.99
HoleShot 2400 for GM 1993 to 1996 TH700R4 (30 spline) and 1984 to 1993 4L60E (30 spline) Application: HoleShot 2400 for GM 1993 to 1996 TH700R4 (30 spline) and 1984 to 1993 4L60E (30 spline) A higher than stock stall speed as delivered by the Holeshot converter will provide several advantages and benefits in vehicles with modified engines. Many modifications, particularly big cams, tend to reduce low end power and torque. The high stall converter allows the engine to launch the car at higher rpm where more torque is available. The Holeshot is generally a very good choice for the typical street machine that is looking for better launch capability and more strength. Street rods with modified engines will also benefit from a Holeshot converter. If your vehicle is equipped with a plate type nitrous system, you will need a Nitrous Holeshot!! Stall speed listings are based on engines producing 230lb. ft. of torque at 2,500 rpm. More torque at 2,500 rpm will give you more stall speed, less torque at 2,500 rpm will give you less stall speed than the stall speed ratings indicated. 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.

  • Steel Alloy Pump Drive Tube
  • Heavy Duty Needle Bearing
