164 top speed ( the mathematical truth )

["Karl Chen" <karlcchen@domain.elided>]

Since some of you are talking about 164 top speed.
Here are the information I collected and calculated 4 years ago.

- ---------------------------------------------------------------------

Calculated from gearbox ratio of 91-93 US. 164S from service manual

Axle ratio( Final ): 3.412

Gear Gear    Over all  Mph/1000 rpm  Speed( MPH )
     ratio   ratio

1th  3.5     11.942     6.03         39.2 mph at 6500 rpm
2nd  2.176    7.425     9.69         62.9 mph at 6500 rpm
3rd  1.523    5.916    13.85         90.0 mph at 6500 rpm
4th  1.156    3.944    18.25        118.6 mph at 6500 rpm
5th  0.916    3.125    23.03        149.7 mph at 6500 rpm( down wind )
R    3.545   12.096     5.95         38.7 mph at 6500 rpm

- ---------------------------------------------------------------------

Calculated from gearbox ratio of 91-93 164-164L from service manual

Axle ratio( Final ): 3.111

3    1.518    4.722    15.46        100.5 mph at 6500 rpm
4    1.132    3.521    20.74        134.8 mph at 6500 rpm
5    0.916    2.849    25.62        140.0 mph at 5464 rpm( realistic speed )
                                 or 153.7 mph at 6000 rpm( and pig may fly )
R    3.545   11.028     6.62         43.0 mph at 6500 rpm

Gear ratios of 1th and 2nd the same as 164S

- ---------------------------------------------------------------------

Calculated from Gear Ratio of 94-95 US. 164LS from Car and Driver 9/93

Axle ratio( Final ): 3.353

     ratio  ratio

1    3.75   12.56     5.7             40 mph at 7000 rpm
2    2.176   7.30     9.8             69 mph at 7000 rpm
3    1.523   5.09     14.1            99 mph at 7000 rpm
4    1.156   3.89     18.5           129 mph at 7000 rpm
5    0.916   3.08     23.3           140 mph at 6000 rpm

R    3.545 11.888     6.0           42.2 mph at 7000 rpm
FINAL  3.353

Gear ratio is the same as 164S except the 1th gear and final drive ratio
