Excessive heat kills transmission and torque converter components. Racing heavily stresses the transmission and causes it to heat very rapidly. It has been proven that for every 20°F your transmission increases, it cuts the lifespan of your transmission and transmission fluid in half. While this is well established and widely understood, we are often asked about the best ways to manage this problem.
Last month, our friend and 2014 NHRA Super Gas world champion Luke Bogacki did a great writeup on his experience with transmission temperatures in throttle stop racing scenario. You can see that on his public Facebook post here. In his testing, he found that elapsed times would vary greatly as transmission temperatures rose above normal operating temperatures. We have found this to be the case as well in our testing and feedback from other customers.
Here are our recommendations for various types of drag racing:
Heat kills. In the middle of the steamy summer, it is even worse. But if you are having trouble in your drag racing car with failed parts or inconsistent performance, a few adjustments to your setup can make the difference between a broken car and a winning car.
