Motor analyser is excellent for non certified or non team motors.
For gearing I don't care at all about temps, the car should be light enough with light enough drivetrain as well as a strong fan to never get warm.
I usually start at 31x72 on the b6 and work from there. I gear by feel and visual speed. If the car stops pulling right off the corner then I know I'm under geared, and if it still pulls on the end of the straight away, then I know I need to go down .
I don't stop there though. I am constantly making changes to gearing until I've absolutely found the sweet spot. If I feel like I'm in between pinions, I'll go with the smaller pinion and bump timing by 5 degrees and see what that does. Gearing is something you should never settle with.
