Stage 2+ Shift Points
I have seen this asked before so here it is. I did this last year with my Stage 2- but here it is revised (sort of) for Stage 2+ on 100 octane. I doubt the octane level would change it much if any as you are not looking at absolute numbers, just relative.
1 - 2 Redline (7k revs or close to it)
2 - 3 6250 RPM
3 - 4 5875 RPM
This is based on the following dyno chart for the <b>relative</b> numbers and the following data:

The effective torque after the shift...
Since the gearing advantage is reduced after the shift you need to calculate what the theoretical torque would be. I use the gearing reduction ratio to calculate the effective torque at the RPM point the revs would drop to after the shift.

I hope 12's are possible, they should be with the right conditions.
Commerce is certainly closer and a nicer track. But it does seem most run a little quicker at Silver Dollar. It is just that 2.5 hour drive that gets me. I can be at Atlanta Dragway in a little over an hour.
One nice thing about Silver Dollar is the lack of crowds.
