370Z maximum speed specification

ImportConvert

Okay, I calculated it all out. I got 168mph using the GT-R's 22.5 sq ft frontal area (couldn't find one for the 370Z, this dyno here:

to plot the points, and 3300# + a 175# driver.

using 500ms shift points, I calculated that this car should run 30-120mh in 16.4 seconds. Car and driver tested a 370Z to run this in 16.35 seconds. Therefor, I am of the opinion that this calculation has a VERY small margin of error that is likely smaller than the variance from car to car. Here is my data, and here is a C&D test-sheet for you to check it against:

*You will note that the whp/wtq displayed is not IDENTICAL to the graph I took it from. This is because I did not agonize over dragging the dots exactly as they were on the dyno. They are off by 1-3# of torque I am sure, as this program allows me only to drag dots, not manually input rpm/power data. However, the horsepower in my data was calculated from the torque, and only being off by a few whp, it is good enough to make me happy considering it is calculated at 5250 and the dyno I took this data from did not have an rpm/tq readout as you can see. In other words: The variance of the data is less than car to car, but I am explaining why it is there.
