lol, "Speed in 5th gear at 6000k rpms = 154" not quite sure about that......

no way to know if that things accurate with my car, my speedo it tells me im doing 75, when in fact im doing 67, and my tach isnt accurate either so i have no way of verifying. Doesnt matter, im buying a Turbo Supra soon!

Looks good if I put in the stock tire size. Never really noticed how fast my z was going at 7000RPM in 3rd gear before this morning checking this chart out. :)

You know it's off 10MPH at what speed? You do know that if it's off 10MPH at 50MPH, it might be off 20 or more further up the gauge?
