That tripping point is the secret. Below it you can use a range of timing and match it with correct gearing. Base that off the time sheets and motor temp. That is the secret to getting it right. One thing I do know from using a dyno. Peak power goes up as you increase timing. Bottom end torque will go down though. Got to get the right spot for the track and you.
