gear ratio's not making sense.

ratios

according to the t-5 information:
85-86 turbo bird 4.03 1st gear.
85-86 svo 3.50 1st gear.

the info for the 83-84 turbo birds and the 84 svo is not available.

My car will run 70 at 3000 but the fuel system will go to open loop at about 73. Acording to my cheep AFR gauge-but it does come off the 0/2 sensor so who knows? The magazine atricles of the time said the speedo was reading 60 and the car was going 61 an unusual event according to them!

My 4.11 geared car runs right at 3150 rpm's at 70mph in 5th gear. Right on with my handheld GPS.

[tateg]

for the ratios in the 2.3L tranny (These #s are from All-data)

1st= 4.03:1 2nd=2.37:1 3rd=1.49:1 4th= 1:1 5th=0.86:1

don't know if it could help.. but "all-data" gave me those numbers for either 2.3n/a & 2.3T mustangs.. sooo I can't tell if its right.

This isn't correct for the all the SVO T5s.

'84
1352-067 Ford 1984 SVO W/Hurst 2.3 EFI TC P 4.03 2.37 1.49 1.00 0.86

'85/'86
1352-116 Ford 1985-86 SVO Mustang 2.3 EFI TC L4 WC S 3.50 2.14 1.39 1.00 0.78

Notice that the later SVO's gearing is unique to that car.

Only unique for Ford. That 3.50 first gear gear set was common in many GM vehicles.

... as well as Nissan 300ZX Turbo.
