HIGH PERFORMANCE, HEAVY DUTY and RACE TORQUE CONVERTER

ENGINEERED QUALITY & PRECISION for MAXIMUM PERFORMANCE on the street or on the track-

WHETHER YOU NEED A CONVERTER WITH GREATER TORQUE MULTIPLICATION, HEAVY DUTY RELIABILITY or RESTORATION UPDATE, SMR CONVERTERS ARE DESIGNED TO SUIT YOUR SPECIFIC APPLICATION.

The objective of installing a modified torque converter is to match the flash stall (the r.p.m. that the converter flashes to under full throttle acceleration from a dead stop and holds at until the driveline reaches that speed) with the designed operating range of the engine. Accomplishing this goal provides maximum engine output and efficiency.

The operating powerband of the engine is determined by the camshaft design, fuel system size and design (eg: carburation, fuel injection, supercharging, etc.),manifold design, cylinder head design, engine stroke and displacement. The converter must be designed to operate within this range. SELECTING THE CORRECT FLASH STALL FOR THE APPLICATION IS CRITICAL IN OBTAINING MAXIMUM PERFORMANCE FROM YOUR VEHICLE.

RACE ONLY APPLICATIONS- Check out our section on Race only converters to determine the correct converter for your application.

Improper converter selection or poorly designed converters will result in poor performance and driveability. Extremely high stall speed and inferior designs can lead to heat generating, power robbing excess slippage, r.p.m. flair up, lost m.p.h., decreased mileage and all around poor driveablity.

SMR TORQUE CONVERTERS are designed to provide the flash stall most suited to the torqueband of the engine WITHOUT EXCESS SLIPPAGE throughout the power range. By reducing slippage after the launch, more of the torque can be utilized to power the vehicle. This design results in more miles per hour without r.p.m. increase, reducing heat and engine wear. This design makes the SMR 10 3/4" ProSportsman (3000) and in most applications, even the SMR 9 1/2" ProSportsman (4000) flash stall converters, very streetable without the light throttle flair up encountered with other brands .

Under normal driving conditions, around town and on the highway, The SMR converter operates like a stock torque converter.

When the accelerator is floored, from a dead stop, without applying the brakes, the converter flashes to its' designed r.p.m. pauses at this r.p.m. point while multiplying torque until the drivetrain reaches this speed and then the r.p.m. increases as it would with a stock converter.

A HIGHER FLASH STALL PROVIDES TORQUE MULTIPLICATION FOR A GREATER PERIOD OF RANGE WITH IN THE POWERBAND.

IN ORDER TO WITHSTAND THE PUNISHMENT OF HEAVY DUTY, HIGH PERFORMANCE or COMPETITION USE, SMR CONVERTERS ALSO RECEIVE EXTENSIVE MODIFICATIONS TO INTERNAL COMPONENTS AND CRITICAL DETAIL TO PRECISE SPECIFICATIONS.

FEATURES INCORPORATED INTO EVERY SMR TORQUE CONVERTER

full FURNACE BRAZING of the Turbine and Pump fins - providing superb strength without interfering with fluid flow or creating aeration.
enclosed TORRINGTON BEARINGS between the cover and turbine, turbine and stator and stator and pump cover - reducing friction between components operating at different speeds - resulting in improved performance and reducing wear and heat build-up.
FORGED STEEL TURBINE HUB (the spline which directs all of the torque and horsepower of your engine to the input shaft of the transmission),
FORGED STEEL inner & outer SPRAG races on a HEAVY DUTY ROLLER CLUTCH (sprag) - to withstand the extreme load demand during torque multiplication (launches) of flash stall.
new ALLOY STEEL PUMP DRIVE (converter neck) to withstand high r.p.m. and high fluid pressures created by heavy duty to competition transmissions. This drive is precision machined to assure maximum converter pressure and precise alignment with crankshaft pilot preventing high speed vibration and component wear.
precision machined PILOT and MOUNTING PADS to assure precise alignment and secure crankshaft attachment.
the turbine is INTERNALLY BALANCED and the pump cover and front cover are also balanced - to provide a vibration free operation at any r.p.m.
the precision welded converter is PRESSURE TESTED to detect any possible leaks and then painted a temperature sensative, high gloss ORANGE to detect an overheating condition.
ANTI BALLOONING PLATES are incorporated into our 8" converters.
KEVLAR and HIGH ENERGY CLUTCH LININGS are used in lock-up models.

OPTIONS AVAILABLE for Special Applications include: SUPER DUTY SPRAGS, MECHANICAL DIODE, STEEL or ALLOY STATORS, CUSTOM DIMENSIONS (for engine plates, special adapters, rare spline combinations, etc.), ENGINE BALANCING WEIGHTS and ALTERED BOLT PATTERNS.
