Hi All

I am just about ready for the SVA and I would like to check the speedo. So could you tell me how fast the speedo says you are going in second gear at 2000rpm. Any indication would help as I can fine tune at SVA. I am running a 2lt pinto type9 box and serria diff.

Thanks Carl (SVA Very soon)

i did mine in top,40 is about 2000 and 60 about 3000,that should get you near enough with standard size tyres

I think you'll find there are a few variables.

wheel/tyre diameter
diff ratio
Amount of teeth on output shaft teeth gear/speedo drive.


Cheers

This may help

the speedo reads of the gearbox usually, so changing diff and wheels wont affect the reading related to revs, only what the real speed is at any given revs. If in doubt, put in a 3.9 diff for the test - you are allowed to read too high i believe.

Thanks that spreedsheet is just what I need.

Thanks Carl
