Where would you shift this combo?
Where would you shift this combo? Car is a stock t56 with 3.50 rear gears. Where would you suggest to shift this and have the rpms drop back into the "sweet spot"?

Looks like typical cammed LS1 profile, but with a lot more power. Is it the car in your signature? Based on the graph shifting around maybe 6700-6800 might work best
You can do the math for max PUC and that will give you great starting point. If you log it that will show how your trans/ clutch/ gears/tires operate and what rpm zone you are in. That's more accurate because it takes into account things like clutch slip and tire spin. Your dyno graph is cut short so you will have to estimate max PUC. From my experience I can tell you that most likely you will want to shift at 7000 or above for most power. Keep in mind if you are spinning excessively then most power may not equate to best et.
Your should experiment with different rpms on the same day and if you are very consistent with each pass use mph as a good indicator. A g meter would be the ideal tool for determining shift points because it takes into account everything mentioned at the track on the day you are racing. But I understand that most people do this for fun and don't have access to all of the equipment available today.
All that being said, I bet you'll want to shift as high as your engine builder will allow safely and consistently.
I'd change the shift rpm 200rpm @ a time and see how the car reacts. Always start lower than what you feel is ideal for a good safe baseline pass.
