hey guys, ok the other night i was coming home from the local track and rode up with some friends one had a 91 mazda b series truck he had cold air and exhaust but since he had a bigger engine he wanted to race just for kicks. we started at about 70mph i put in 4th and he did to, bigger engine pulled away but i noticed my rpms were actually quite low i thought i could only get up to about 80 in third gear but i was wrong then i told him i wanted to go again, to 3rd this time a got up to about 95 in 3rd and i left extremely quick. but i was wondering how high can everyone get in third gear? when i first got my car i could only do about 80 but ive recently started putting plus gas in my car and figure that to be the reason. am i right?

What are you talking about? You should be able to hit your 6800 RPM limiter in third gear easy. 4th is a hard gear to hit the RPM limiter because you hit the speed limiter first. So is 95 mph when it hits the RPM limiter in your car in third gear? Do you have a manual or auto?

hehe, yeah... the od off button is handy when you need to cut @ like 70 mph. or when a gay civic wants to race and you beat him even tho your car is speed limited. (fwy)

I always wondered about 3rd and 4th gear in an auto. I have a 96 Sentra GXE. When I have tried to top out my car I have always turned off O/D and used 3rd gear but when I start getting really high rpms you can tell that the engine is definately getting to the end. How high can I go in 3rd gear? Can I just use 3rd to get all the way to the top or will I have to switch to O/D? I would like to know how high I can get my car but I dont want to blow up my engine just because I ran 3rd gear all the way to the bitter end!

This still doesn't make sense. Your car should still be able to hit the rev limiter with 87 octane or 100 octane. The gearing has always stayed the same. Did you ever really try to hit the rev limiter in third gear back then???????

Calm down KILLAZ! Don't jump a man for asking a simple question. Even if he didn't state is right

"when i first got my car i could only do about 80 but ive recently started putting plus gas in my car and figure that to be the reason. am i right?"

does anyone actually know the real top speeds for these gears? I know my owner's manual says the top rated speeds for each gear but is that accurate? I'm sure there is a little play in there for safety's sake and to take some liability off of Nissan. BTW my car is an auto so I don't know about the 5 speed.

Oh ok. I guess I will just have to do my own testing on my car to find out about the autos. Too bad I'm scared!
