I am trying out 7.1:1 with the motor at 35*, trying to get a little more top end, and keep the low strong.
my track is a little tight, and the 12.8 may help a bit on the low.
the overall power should stay the same, just shift the curve where the power band will be.
What is the temp after 5 min and 10 min? You want to make sure you have two different ratios setup, one for qual and one for mains.
Before you switch, get a baseline temp after 5 min and after 10 min. Do it 3 times each if possible so you can rule out any flukey readings. Once you know that you are at 110 after 5 min and 140 after 10 min (I'm just making up numbers), then you can use that gearing as a road map to your 12.8 gearing.
