Weight and the converter
Does the weight of a car change the stall of the converter? For example if a converter stallls at 4800 in a 3400 lbs car and you remove 200lbs does it change or stay the same?

Re: Weight and the converter
The stall of the converter has to do with the horsepower supplied by the engine to the converter and nothing to do with the weight of the car until the car is launched when the converter starts to do its work.

Billy, Well said!
It will also change the way it works if you change gear ratios. A deeper low gear will make it act like it is tighter. |

A good running Powerglide car does so, in spite of having such a high 1st gear ratio, because the converter is forced to "work harder". As another example pertaining to weight; A street and strip car with a high stall converter,cruising along on the freeway, comes to a hill or rise in the road. The effect of the hill is that the car thinks it's "heavier" and the RPMs will rise, while maintaining the same MPH. You've got to remember,unless it's got a lock up clutch it it, it is a fluid coupling |

At least in our cars, the engine goes past the torque peak then settles down at a lower torque value for flash/stall. And keeping everything equal with gearing and weight, in good air it will flash at a higher rpm with increased torque. |
