Wheel spin in 2nd

The 7AT has even more effective torque due to its gearing (I have a spreadsheet I haven't posted on it yet...) Since the torque curve is so flat, the car

The 7AT has even more effective torque due to its gearing (I have a spreadsheet I haven't posted on it yet...)

Since the torque curve is so flat, the car makes around 200 rwt from around 2500 RPM to 6500 RPM, so the 7AT has 3300 in 1st, 2141 in 2nd and 1370 in 3rd versus the manual's 2800 in 1st, 1713 in 2nd and 1196 in 3rd. With the heavy flywheel/rotational mass of the 370Z's engine, that makes wheelspin at shifts even more likely. Even assuming a cf of 1.5, seems like we have enough force to spin.
