I think the owner's manual lists the top speed for each gear. Can somebody check it up and post here. My owner's manual is in my glove box, and my car is parked 10 minutes away, so I don't feel like getting out there to check it up. I need to do a power curve calculation for a Mechanical Engineering class and knowing this info would help me make more accurate calculations. Thanks!

 

First of all.
Which car are you talking about.
Second get your lazy *** to your car.

 

Any Civic is fine. I'm actually doing calculations for a b16a2, but I would imagine that the top speed for each gear is about the same for all Civics. Don't feel like walking for 20 minutes if ya know what I mean.

 

No all civic gear ratios are not the same.

Civic HX has long as **** gearing.

My b16 goes like this

1st - 42 mph
2nd- around 60 mph
3rd- 98 mph
4th- 123 mph
5th - havent topped out yet

 

what kind of tranny do u have

 

just curious, how did you get your car to go that fast in 3rd gear? the most i have ever gone was a little above 80. thanks

 

Im not exactly sure what tranny it is...i think its a YS1? Its the hydro LSD tranny that came with my swap, im not to familiar with tranny codes. Everyone seems to doubt, so i think im gonan try and get some video of it.

 

4.4 fd is just about that.

 

92-95 tranny info thanks to mistabone

Thanks for the posts guys. I just made some calculations and they are as follows. The hp of a b16a2 peaks at 7600 rpm, so the speeds listed are at 7600 rpm, which is probably near top speed. The gear ratios are from a Civic Si.

Axle ratio: 4.4
Tire diameter: 23.5 in

Speed=2.97*[(Tire diameter*(RPM/1000))/(Axle ratio*Gear ratio)]

Gear (ratio): speed @ 7600 rpm
1st (3.230): 37.3 mph
2nd (2.205): 57.3 mph
3rd (1.458): 82.7 mph
4th (1.107): 108.9 mph
5th (0.848): 142.2 mph

The calculations can be done here for any car. Just input all the required info and get the speed for any rpm, or the rpm for any speed:
