what MPH at what RPM

[ZackieDarko]

my spedo stoped working and i need help!


my spedo broke but the tach still works

my question is, and i did use the search button, does anyone know of a chart that shows what speed you are traveling at a given speed in a given gear?

i have seen some calculators on the net that will tell you what speed you are going at a given rpm in a given gear but they require more information that i have to give you these numbers

thanks guys

these are the shift points in the manual:

Normal Acceleration
2nd - 15 MPH
3rd - 28
4th - 41
5th - 52

Cruise from Acceleration
2nd - 7 MPH
3rd - 22
4rd - 33
5th - 48

i'd say the top speeds are around 3K - 3.5 and the bottom ones around 2.5ish.. (like if you're going at 3.5K rpm you're roughly at 48mph if youre in 4th

not really complete information but perhaps useful lol

it's hard to say for sure though..

no my spedo DOESNTWORK so i DONT KNOW how fast i am going unless i am at 3000rpm in 5th

i would like to know what speed i am at at say 2500rpm in 5th or 2500 in 4th or 3000 in 3rd those kinds of things

3000 rpm in 4th is about 55-60 mph
3000 rpm in 5th is about 70-75 mph.
2250-2500 rpm in 5th is about 55 mph cuz thats whenmy car surges like mad.

Load and up and down hills wll make them a little dfferant.

3000 rpm in 1st is 10-15mph
3000 rpm in 2nd is 30mph
3000 rpm in 3rd is 45mph
3000 rpm in 4th is about 55mph
3000 rpm in 5th is about 70mph

it depends if your car is carbed or EFI, the final drive ratios are different.

Let us know your car's year and trim

I don't see how this is possible for a manual transmission--gear ratios aren't a function of transmission load. Are you referring to an automatic?

put 4 people in it an try it.

I dont have an engineering reason other than some loss in the drivetreain.

I might be able to find something at home to help you out here. I'll look into it this evening.

As far as load effecting it, that's because of the additional weight, there's no difference in the transmission.

i know whats wrong with it too but i dont have access to the cable that i need to fix the stupid sipedo what i miss most is my cruise control man i love cruise control
