The trick is never dumping the clutch. You have to learn to bleed off the excess power with some slippage. Too much slippage will kill your clutch. Too little and your launch will occur outside the fatter part of the engine's torque curve. Balance is the key. Practice on wet roads to educate your left foot.
Wheelspin only helps you ramp up the torque. In many cases, it only makes the track longer by the total circumference spun without obtaining forward motion. If you can determine what 12-16% overall spin feels like underfoot, then you'll have the hang of it. The rest should be eaten by the clutch.
