I am not familiar with the specific AT/MT parasitic driveline losses on the Z, but I'm sure if you do some research on dyno numbers of stock AT vs. stock MT, you might have your answer, but each dyno is different so it's hard to say.
General rule of thumb dictates that the loss on a MT is 15% and the loss on an auto is 20%. That being said, on the 370Z they both SEEM to be around the same, if anything 15% for the MT and 17% for the 7AT
