370Z top speed record?

Well obviously the car hits ~155/160, there's no point posting those. That's where the stock ECU speed limiter kicks in. The question is mapping out drag limit vs available torque (a function of both engine and gearing) beyond that. I think the 175-ish numbers seem reasonable for a bolt-on N/A, I can't imagine much higher than that without boost.

Then again who cares really, it's just a meaningless game of immaterial numbers? Pretty much a non-issue on road-courses that I know of; I can't imagine hitting the drag limit on one. I could hit maybe 150 on a perfect day at the most ideal track setting around here I can think of, for a split second before slamming on the brakes again.

Getting up into drag-limit territory on the road is... risky at best without at least some cleared traffic and a radio spotter? Conscious visual reaction times are on the order of ~250ms+ (some researchers say significantly more since it's a Choice-level reaction on driver inputs), and in that time at ~170mph, you've moved almost 10 car lengths. That's assuming you even see the problem before you hit it (like a small rock in the road, or a rabbit jumping out). At least at the track you have relatively-predictable conditions and corner workers with flags.
