Hey all not sure if anyone has noticed but the Focus St is advertised as having a six speed box. Thanks to the Adelaide car show I grabed some of the info on the car (as well as every Falcon thing I could get my grubby hands on!)
and discovered that the car infact runs a four speed box with a second gear on the diff. so the box runs like this
1st 4.410 diff of 2.87
2nd 2.670 diff of 2.87
3rd 1.330 dif of 4.24
4th 1.080 diff of 4.27
5th 1.330 diff of 2.87
6th 1.080 diff of 2.87
Now could something like this be put in place to allow a real normal/power button on a falcon?
Ie final drive of 2.77 for normal driving (making for around 1500rpm for 100kms and say 3.45 for sport mode? (my guesses are for what would suit a 6 btw)
Sounds like a great idea for me and would mean the ability to get dead sexy quarter miles but still have good normal drive economy.
2 speed diffs have been around for a milenia on trucks shouldn't be to hard to do.
