Product Details

Nitrous Holeshot™ Torque Converter (20485) by B&M®. Material: Steel. 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.

The reason for considering B&M torque converters boils down to performance. Higher stall speed is the key. A higher stall converter allows the vehicle to accelerate better from a dead stop and may provide tire-smoking performance. B&M offers a wide range of performance torque converters to fit almost everybody's needs. From the Tork Master, to the Nitrous Holeshot for street applications to the Quick 60 Race converters for racing, B&M has the right converter for your vehicle. All B&M converters are precision engineered, spin balanced and pressure tested.
