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.

Stall speed listings are based on an engine producing 230 lb. ft. of torque @ 2500 rpm.  More torque @ 2500rpm will give you more stall speed, less torque @ 2500 rpm will give you less stall speed than the stall speed ratings indicated.  Engines smaller than 350 cid may not produce the torque at 2500 rpm to achieve stall speed indicated.

Note:  Holeshot converters are NOT to be used with a transbrake
