Well I dont know that I would listen to me over Brice (American Speed) as he ran 12.8 with just a CAI/Tune. I never ran better than 12.91. Of course I like to think it was my 280 lb weight at the time but..... The point is some cars can be launched from a lower rpm like Scott's (13.2 in a 100% stock 2005) who left from 3000 rpm and cut a best of 1.83 60'. He tried that in my car and never did better than 2.01 (bog city). My car is quickest with a touch of tire slip. His was quickest when you never squeeked a tire and controlled it all with the clutch.

1. Intial spin: reduce rpm or increase slip
2. Initial hook followed by spin... Decrease rate of throttle increase or increase time of clutch slip.
3. Bog only... raise rpm
4. Spin then bog.... Increase clutch slip and rpm.

That's what works for me in my car but even two good drivers in the same car may use different techniques and two identical cars may require significantly different techniques. These are just a place to start from. From their its simply practice and experience and your developed style may be a bit different from another equal driver.
