Description

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 Holeshot converter allows the engine to launch the car at higher rpm where more torque is available.

The Holeshot is 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.

FEATURES:

Furnace Brazed Impeller
Steel Alloy Pump Drive Tube
New Springs/Rollers In Stator
Heavy Duty Needle Bearings
Furnace Brazed Turbine
Dual Pattern Drive Lugs
New Turbine Hub

B&M Holeshot Torque Converters Hot Deals

B&M HoleShot torque converters are designed to improve acceleration and increase drivetrain strength in most street machines. A nice benefit of a Holeshot high stall torque converter is when a higher duration camshaft is used, you can expect improved engine idle while stopped in gear. These high quality balanced torque converters come standard with full furnace brazed impeller and turbine, heavy-duty needle type thrust bearings, and new turbine hubs.

Note:
◦Not for transbrake applications.
◦Stall speeds may not apply to engines smaller than 350 cubic inches

Features:
•Rated up to 600 HP/500Ft-Lbs
•Furnace brazed impeller and turbine
•New precision steel pump drive tube
•Dual pattern drive lugs on some GM HoleShots
•New turbine hub
•New springs and rollers in stator
•New heavy duty needle bearings used instead of thrust washers

Stall Speed: Very mild street cars use a 2000 RPM stall speed unit. Most street-driven performance cars with 350 foot pounds of torque or more need a 2400 RPM unit. Cars with more radical small blocks (500 foot pounds of torque at 4500 RPM or higher) require a 3000 RPM converter. The more torque a motor puts out, the higher the resulting stall speed. Therefore most street performance big blocks would still use a 2400 RPM converter because they generally achieve 2600-2800 RPM. An engine smaller than 350ci might not achieve such stall speeds, which are based on an engine producing 230 foot pounds of torque at 2500 RPM.
