Product Details

Nitrous Holeshot Torque Converter (20484) by B&M®. B&M Nitrous HoleShot 3500 stall for GM 1965-91 TH400, TH425, TH375 and 1968-81 TH350, TH375B (not TH350C.) The Nitrous Holeshot 3500 stall converter are an excellent choice for vehicles with many engine modifications, particularly big cams that tend to reduce low end power and torque. The higher stall speed of this converter will launch the car in a higher rpm range where more torque is readily available, resulting in quicker acceleration. Nitrous Holeshot converters feature furnace brazed impeller and turbine, new precision steel alloy pump drive tube, new heavy duty needle bearings between the stator and impeller (not a thrust washer) and needle bearings between the stator and turbine. Other features include dual pattern 10.75 and 11.50-inch bolt circle, a new turbine hub, new springs and rollers in the stator and anti-balloon plates. The anti-balloon plates will allow these converters to stand up to the instant horsepower that a nitrous plate system delivers. 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. These are serious converters for serious performance street cars. To prevent contamination left from worn parts being circulated in your new components causing premature wear, we strongly recommend protecting your investment by adding a B&M transmission cooler with all new transmission installations. Listed converters are NOT to be used in trans-brake applications. Not for use in trans-brake applications. With the addition of anti-balloon plates, the Nitrous HoleShot is the strongest of the B&M street converter line. These converters will take the “instant hit” abuse of plate-type nitrous systems, and are also tough enough to handle the high power and torque of big cubic inch crate engines. All Nitrous HoleShot converters are completely balanced with full furnace brazed impeller and turbine, heavy duty needle type thrust bearings, new turbine hubs and anti-balloon plates, these are serious converters for serious performance street cars. This converter is NOT to be used in trans-brake applications.
