How come some rx-8's have higher redlines than others. My girlfriends car goes to like i think 8000 and i've seen some that go to 9000 and show up to 10000? Why is that?

 

automatics have lower redlines than the MT.
if your GF's car is a MT, then it goes to 9K

 

well, if its a MT then it GOES to 9.5k :P however the redline is 9k. fuel does not cut till 9500 so it goes till then and stops

but hes right, about the autos having lower redlines, i thought it was 7500 tho? i could be wrong

 

well yeah, I don't make it a point to run it till the fuel cuts out, lol...so i say 9k to be safe

 

well i dont hit the cut, i prolly shift at like 9300 or 9400. of course thats only when im feeling really spirited! its just such a crazy noise that high up on a car
