Does torque converter stall speed mean

These variables include:. As always, we recommend you consult the torque converter manufacturer or talk with your friendly Summit Racing sales rep before ordering your torque converter. David, nice article. Street rodders have a unique problem. They love the sound of a good cam and are not to interested in launch starts. We order stall converters to free up our idle rpm so the car does not go dead or set at a light jerking and trying to go.

Do you have any info that could help in making a decision of stall speed for this problem. I know lift, duration and separation or center line of the cam are factors to use but this is a challenge.

Kind of a guesstimation. Thanks for any thing you could share. Roy Newberry rnewberr bellsouth. In talking with TCI, there are some basic recommendations based on cam duration, gear ratio, and desired engine characteristics. You can find them on this PDF on page Hope this gets you going in the right direction!

I have a 3tc Toyota piston engine at adopt 10 to 1 ratio. Flash test reads rpm. Can you lead me in the right direction. Thank you so much. Why am I trying to measure stall speed of a torque converter with a manual transmission? I believe they are referring to a manual valve body automatic transmission as it will not kick down to a lower gear when floor the accelerator. You could disconnect the kick down linkage or cable on older vehicles but computer controlled transmission it may need to be changed by a tuner….

The impeller input side of the torque converter is spinning quickly, while the turbine output side is spinning slowly or not at all. The motion energy of the impeller is being converted into heat energy, most of which is passed on to the transmission fluid.

Now if your talking a 60 mph roll then not as much will be noticed but from a 15 mph roll then like others hacve said HANG ON. We know that for any level flight not climbing the amount of lift must be equal to the weight of the aircraft, thus if all up weight is lower then the amount of lift required is less too. A bad torque converter can damage a transmission.

Bad torque convertors can lead to damage, overheating, friction, and transmission fluid degradation. If these problems continue, it can cause even more damage to transmission. When the torque converter starts malfunctioning, you may feel shuddering and even slipping in overdrive.

The shuddering makes the car lag and is very noticeable. Skip to content What does stall on a torque converter mean? How do I know what stall converter I need? Is a stall Streetable?

When the first fan blows, it will turn the second fan. However, if you hold the second fan still, the first fan is still able to run. The fluid inside a fluid coupling allows the turbine to stop, start, or run at slow speeds while the input shaft may still be turning at high RPMs. However, once the fluid has passed through the turbine, it must return to the pump to cycle through again. The stator alters the flow of the fluid so that it matches the pump rotation.

The stator modifies the fluid as it returns from the turbine to the pump.
