LOL, you guys crack me up. An ideal launch would be to get moving without spinning your tires much and none at all would give you a really good launch.
Basically I like to launch the car around 2500-2800 and then let the clutch slip a little to keep the power to the ground. This will cause extra wear, but it's better than just dumping the clutch and you'll get wheel spin.
Its up to you!
