Nitrous Holeshot 

- Recommended for Street Rod, Pro Street & Street Machines with Plate-Type Nitrous Systems

Nitrous engines produce some serious horsepower and require a serious torque converter to handle it. The newest line of street performance converters from B&M is the Nitrous Holeshot series. Built with the same features as the other B&M Holeshots with the addition of anti-balloon plates. The anti-balloon plates will allow these converters to stand up to the instant horsepower nitrous delivers. Converters with higher than stock stall speed will allow the vehicle to accelerate better from a dead stop and it will allow the vehicle to idle better when a big cam is used. The Holeshot is a good choice for the typical street machine, however when nitrous is used the Nitrous Holeshot is your only real choice. The Nitrous Holeshot 2400 is also an excellent choice for big cubic inch crate motor applications. Fully furnace brazed, heavy duty needle bearing thrust packages and new turbine hubs are the key features along with anti-balloon plates are found in the Nitrous Holeshot converters. These are serious converters for the serious street performance car.

Stall speed listings are based on engine producing 230 lb. ft. of torque @ 2,500 rpm. More torque @ 2,500 rpm will give you more stall speed, less torque @ 2,500 rpm will give you less stall speed than the stall speed ratings indicated.

Holeshot

- Recommended for Pro Street, Serious Street Machines & Street Rods

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 a 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 engine has a plate-type nitrous system, you need a Nitrous Holeshot.

Traveler

- Ideal For Motor Homes and Towing Applications

The Traveler converter is intended for use in motorhomes, tow vehicles or other heavy duty applications where a slightly higher stall speed is helpful in getting the vehicle moving. The Traveler is also stronger than a stock converter and has been internally modified to provide about 300 rpm more stall speed for help in initial acceleration without sacrificing normal highway operation. It is manufactured to B&M’s exacting tolerances for long life.
