This is the second segment in our series on stall speeds. We are sharing advanced stall speed advice because we believe that the more our customers know about torque converters, the easier it will be to shop for them.
In part one of our series, RevMax Performance Torque Convertersintroduced the basics of stall speed and why it is important. This post will give more advanced information on torque converter stall speeds, how it will affect your driving and how to measure your stall speed.
Torque Converter Stall Speed and Driving
Generally speaking, your normal driving is not adversely affected by converters with stall speeds up to 3000 RPM. Your vehicle will begin to roll normally and acceleration will be favorably influenced when high stall speed converters are used. A very high stall converter (greater than 3000 RPM) would not be satisfactory for street use. Unless you are into doing burn outs at every stop light, higher stall speeds are inefficient.
How to Determine Your Stall Speed
To get an accurate reading of your vehicle’s stall speed, you will need a transbrake to lock the drive train. Testing your stall speed by holding the wheel brakes and running the engine against the locked brakes (power braking) will cause your wheels to rotate before your true stall speed is reached.
Another method that you can also use to measure your stall speed is to launch a wide-open throttle and observe the engine RPM reached at launch. This is commonly referred to as flash stall. However, doing this will cause your engine’s power to push your vehicle before it reaches its true stall. For the best result, we highly recommend using a transbrake.
Things to Consider When Buying a Torque Converter
Sure, stall speed is very important, but it is not the only factor to consider when buying a torque converter. You should also consider torque multiplication at launch and high-end efficiency. Selection of these components will not only affect your stall speed, it will also affect your converter’s efficiency.
- Torque multiplication is the maximum amount of torque produced from your engine through the torque converter to the transmission and your wheels.
- High-end efficiency is the measurement of how the torque is actually used. In other words, how efficient is the torque you’re producing.
