hi! my car is 107hp. what is better? now i have 17 64. all tell me is very long for 400 meters. and vs for other cars. if i put 13 53 is true go very faster for 400 meters? thank you!
 
Probably a little faster in 400 meters, if you have good traction. What size tires?
There is also a 12/53 from the 128 estate (wagon).
 
Are you looking for the fastest 400m run? You have a motor built for revs, so your transmission would be want to allow the use of those revs.
 
The 13 53 (4.08:1) is lower geared than the 17 64 (3.76:1) so that would give the better acceleration. The 12 53 would be even better, if that is what you are after.
 
hi thanks for respond. have big diference at the road? my is 110hp. with 13 53 400 meters i go very faster or small diference only? have do it any here to tell me before and after? thanks.
 
I would not do the 12 53 unless you have a limited slip or something. Too much torque steer. The other problem is you will be shifting more often and 7500 rpm in 4th will come out to 75mph/120Km h. Stick with the 13 53. As noted, the 17 64 is probably not a good idea either, the rpm gaps between the gears, especially 3rd to 4th is pretty large.

Does that help at all?
