My car’s been over 200km/h, auto S13 coupe. I pinned the HUD to 199 and just keep on the gas… I figure 205-210. I wont do that again until i get a better/more stable suspension.
edit: oh since i’m on 205’s it’s + 2.6% or something like that.
The stock gauges are wrong. 190km/h = 180km/h at speed.
100km/h is about accurate, and then it starts reading too fast above that.
So if my speedo shows 185ish, im prob doing 175ISH?
It should be a percentage and with your numbers it’s -0.05%
my s14 went a ways past 200, no speed cut, i dont know why…
no thats not what im saying.
100km/h = ~100km/h
the speedo was physically printed wrong, the percent it was off would vary depending on how fast you were going. At 40km/h you are really going like 41km/h - then its accurate up till about 90, around 100 you’re really going 98 or so… and it just starts getting really inaccurate from then on. This is just from my memory of my RSM and my speedo though so its obviously not precise those are just general figures as close as I can remember.

you mean -5% or 0.05 times smaller right?
