180Q Torques--BIG difference

Due to remarkable gearing diffs in Q compared to FWD, offer the following:

SHIFT TORQUE UNITY RPMS
---------- -----------------------------------
1>2.............unavailable...6660 = 55 lbs. loss
2>3.............unavailable...6600 = 4.3 lbs. loss
3>4.............~6225
4>5.............moot since 4 & 5 gearing so close

from what I'm seeing, Q seems to have
PEAK TORQUE
1.......3000 RPM
2.......5500-5550 RPM
3.......4700 RPM
4.......4150 RPM
5.......3000 RPM

Guess that's why I like 2nd so much....

180Q has different final drive for 5th gear, so it translates from 0.97 to 0.76

Yes, I know someone posted those ratios without compensating.

Shift points for the 180Q are higher than for the FWD (unless at redline in lower gears) since the gaps between ratios are larger.

Peak torque in each gear is at same rpm's, namely all the way from 1950 to 4700 (according to factory specs). In reality there will be imperfections in that flat curve, but peak torque in each gear must come at same rpm regardless of which gear it is.
