Not sure what you mean by being afraid to "roll it out at all," sorry.

What I meant by that was rolling off the clutch real slow at a mid to high rpm (like a softer launch) as opposed to letting it out quicker (like in a hard launch). Does that even make a difference as far as how much strain your putting on it?

That's called slipping the clutch. If you do that at lower rpms, it burns through the clutch and wears it out faster. Doing it hard and fast but with a slight slip will not be as bad but will have more potential for either spinning tires or hurting the drivetrain. I launch from 6k with a hard slip. If you try to launch from 4-5k, you will either bog (very slow but no harm done), or you will burn straight through the clutch and go immediately to 7k rpm while barely moving.

that has to vary based on what power you're making. I consistently launch mine right around 5k for autox, and rarely have any slip. usually a little wheel spin, then off we go.

It does vary by power, but I'm talking about an Evo with the stock turbo. You are probably getting away with it in autox, because your tires are inflated to 40psi, and it's not a VHT-covered drag strip.
