With the addition of anti-balloon plates, the nitrous Holeshot is the strongest of the B&M street Converter line. These convertes will take the "instant hit" abuse of plate-type nitrous systems, and are also tough enough to hndle the high power and torque of big cubic inch crate engines. All nitrous HoleShot converters are completely balanced with full furnace brazed impellaer and turbine, hevy duty needle type thrust bearings. new turbine hubs and anti-ballon paltes, these are serious converters for serious performance street cars. Listed converters are NOT to be used in trans-brake applications. To prevent contamination left from worn parts are being circulated in your new componetns and causing premature wear, we strongly reccomend protecting your investment by adding a B&M transmission cooler with all new transmission installations.
