Is lower stall speed better?
Converter stall speed must be high enough to put the engine into the torque range where it can most efficiently launch the car. If converter stall speed is too low, the car will be lazy leaving the line; if too high, there’ll be excessive high-gear slippage—either case adds time to your e.t.
What does a stalling speed mean?
Stall speed is defined as the minimum steady flight speed at which the airplane is controllable.
Does stall speed change?
Stall speed increases as weight increases, since wings need to fly at a higher angle of attack to generate enough lift for a given airspeed.
What are the factors that go into stall speed?
The main factors that go into calculating the stall speed for any car include the weight of the car, the circumference of the rear tires, the gear ratio, and of course, the engine’s performance level.
What causes a car to flash at a higher stall speed?
As mentioned earlier, besides the engine’s ability to produce power, the weight, gear ratio, and tire height all play a role in what the converter’s stall speed needs to be. The heavier a car is, the more load it will put on the torque converter when power is applied, causing it to flash at a higher speed.
Do you check stall speed on the footbrake?
Checking for a stall speed on the footbrake isn’t the most accurate way because you’re only at part throttle and not making a large amount of torque, so the converter will not see much stall speed. Stall speed is a relative term. It only reacts to a situation; it does not dictate anything.
How does the height of the rear tire affect stall speed?
Tire height falls into the same function zone as the gearing of the car: as you increase the height of the rear tire, you will increase the load on the torque converter and change where the torque converter will flash. There can be some confusion that the stall speed of a torque converter is an absolute thing.
