URGENT! 2.92-3.45 Speedo Difference

Hi,

Im headin on a holiday to kalgoorlie WA tonight and my car is currently at the diff shop getting a LSD with 3.45 gears put in and the 2.92 S/S out. The speed limit along the great eastern hwy is 110, i dont have time to calibrate the speedo.

Anyone know what i should sit on for 110?

Cheers

Brett

110 x (3.45/2.92) =129.96km/h

Good luck dude. There are tons of hidden multanova cameras along the GE hwy. I'm in their hall of fame!

Brett,
this is probably a bit late, but something you can do when you get home.

Ford use colour coded speedo drive, and driven gears.
What you need to do, is remove the speedo sender, shine a light in the box and note the colour of the drive gear.

Then go into a ford parts dealer, with the drive gear colour, diff ratio, rim size and tyre profile. They normally can supply over the counter.
Also get a spare clip, sometimes they break when changing the driven gear.
all for less than $5.00....cheaper than a speedo-calibration

cheers
