All About Stall

So far, our All About Stall series has focused on engine setup and its effect on torque converter stall speed selection. We’ve covered the importance of things like camshaft selection, engine operating rpm, and even exhaust backpressure. Another key part of the equation, according to ACC Performance president and CEO Nelson Gill, is vehicle setup. Vehicle weight, gear

Our initial All About Stall post established the significance of engine setup in choosing torque converter stall. Nelson Gill, President and CEO of ACC Performance, then demonstrated how variables in engine setup — things like cylinder heads and exhaust choice — can change your ideal stall speed in Part 2 of the series. So where do you start when trying to pinpoint

In Part 1 of our All About Stall series, we shared three factors to consider when choosing torque converter stall speed range: engine setup, vehicle weight, and rear gear. When considering engine setup, the tech experts at Summit Racing suggest using the camshaft powerband as a starting point for choosing stall range. However, there are

Stall speed is essentially the engine rpm at which a torque converter transfers the torque of the engine to the transmission (see our earlier post on how a torque converter works). When choosing a torque converter, it’s important to properly match its stall speed with your vehicle setup. According to Nelson Gill, President and CEO of ACC Performance,
