Craig, Here are the V4 gearbox ratios straight out of my old Saab V4 service manual; 1st= 17.0:1 2nd= 10.2:1 3rd= 6.3:1 4th= 4.1:1 R= 15.5:1
The differential ratio is 4.88:1 with the ring gear having 39 teeth and the pinion having 8 teeth.
The book says that at 1000 RPM you should get these MPHs;
1st= 4.2 mph 2nd= 6.9 mph 3rd= 11.2 mph 4th= 17.1 mph Rev.= 4.5 mph
That is with 155 x 15" tires.
Enjoy.
