This is a curiosity question for those of you driving TR-2/3As with
the 1.991 Liter engine and the 3.7 rear end. I wonder what shift point you
and the car 'like' when upshifting; i.e., at what RPM do you upshift?
Shifting at a point just past the shoulder of the torque curve gets
you the best acceleration, since when you upshift, you then
drop to just below the shoulder and are in the right position to
accellerate in the higher gear.
The torque curve in the shop manual says max torque is118 ft-lbs
between 2500 and 3700 RPMs. Also, the right point is often discernable by
feel. I have my own preference, but am interested in the experience of others.
Thanks.
