The Holeshot converter is an excellent choice for vehicles with some performance 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. Holeshot converters feature furnace brazed impeller fins and turbine, new precision alloy impeller hub and new heavy duty needle bearings. Other features include fully balanced and pressure tested by expert technicians. If your vehicle is equipped with a plate type nitrous system or supercharger, please refer to the Nitrous Holeshot line of converters. Notes: 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. Higher stall converters can generate more heat, so we highly recommend adding a transmission cooler. This converter is Not recommended for supercharged, plate-type nitrous oxide or trans-brake applications.

  • Since the very early 1950s, B&M has been at the vanguard of the growing automotive aftermarket. Racers themselves, B&M's founders identified the needs of local racers and street performance enthusiasts, and developed products to fill those needs. As the industry grew so did B&M. And as racers went faster, B&M developed products to help them break the records they just set.

    In the 50s it was B&M who came up with the idea of using a performance reinforced Hydramatic for racing. In the 60s it was B and M who developed shifters to go along with it, and later in the decade came race converters. In the 70s shift and transmission improving kits, and always the constant refinements and expansion of existing product lines.

    If you've ever raced a vehicle, or driven a hot rod with an automatic transmission, high stall torque converter, an aftermarket automatic shifter, or performance enhancing shifting kit - thank B&M. From Trick Shift performance ATF to reverse pattern valve bodies, 1.80 gear sets to cool canisters, the list of firsts goes on and on.
