My general question is would I be better off going into the turns in 2nd, thereby gaining a little bit of a power advantage coming out of the turn, but requiring an extra shift in the following straights to maximize my speed?

The wrinkle in this is that torque starts to fall off at around 6500 RPM so I'm not sure whether I would be in 2nd long enough to offset the shift.


well, since you have the logger.. simply try it and see how the numbers look..




I generally would want to power out at maximum grip, so if you downshift to 2nd and don't spin/get squirrley, then do that

if 3rd gear keeps you better composed.. do that
