: : Thanks for your general comments, Luis. Now, specifically speaking:
: : Do the closer ratios of the 5 speed provide a significant difference in quickness?
: Not really
: : How similar are the ratios of 4th gear in the 262 and the 265? Troy listed a difference in rpm @ 80mph of ~700 between 4th and 5th for a 5 speed, if I read his post correctly. Could I expect the same difference between top gears in the two transmissions?
: Very similar... sorry, I'm at work and don't have the reference of gear ratios from Haynes. The variance, from what I recall, is in the middle gears (2nt to 3rd, I think). Nonetheless, I will think if you find a CR (Close Ratio) 265 then you may experience significant improvement.
: In my experience with 2nd class German engineering (just kidding) the beefing is in the first two gears. That's how they make VW to drag race, which is not seen/obtained on the 265.
: I don't recall anyone posting ratios for the CR 265... Anybody has such info???
: If you really want to fly (well that's exagerated, but feel a real difference, then you need both a CR-265 and an LSD from a 80/81 Six series. But.... then you may as well buy the whole car.
These are the ratios:
Getrag 262: 1. 3.855, 2. 2.203, 3. 1.402, 4. 1.000
Getrag 265: 1. 3.822, 2. 2.200, 3. 1.398, 4. 1.000, 5. 0.813
CR Getr265: 1. 3.717, 2. 2.403, 3. 1.766, 4. 1.263, 5. 1.000
Therefore there is no real acceleration advantage from Getrag 262 to 265, only the advantage of lower rpms and higher mpg on the highway. The Close Ratio 5 speed will give some acceleration advantage but no overdrive advantage. That would be more useful on a track.
