OK,
This one has bugged me for years, but finally got around to posting it. The reason is because I'm more than doubling torque ratings on my car, and as it gets older, transmissions won't be cheap.
Let's say that you have two transmissions, for this exercise, rated at 166 pounds feet torque.
-One transmission has a 3.94 final drive
-One transmission has a 3.55 Final drive
-Both are straining against 370 pounds feet of troque.
-There is the same traction and a Quaiffe LSD installed for each
Which one fails first? My thoughs go back and forth. The higher numeric geared tranmission means less load on the input shaft., but more on the output The other would have more load on the input shaft I'm thinking, because of less output power?
Am I thinking about this all wrong?
