This of course depends on how tough your clutch is. If you have a fairly weak clutch and just dump it, it might slip just enough and get you moving or it could keep slipping and glaze. If you have a strong clutch and not enough power to spin your tires and dump it, that could be bad.
My best luck with a strong clutch is to slip the clutch just enough to get the car to barely start rolling and then dump it with your foot still on it (no sidestep) That way the clutch takes the initial shock and the driveline has a chance to take up any slack and tighten up before you lay the pain down. Of course if you lack the power to spin the tires or the clutch bad things could happen.
As far as rpms go, it depends on your powerband. You want to launch high enough to where if you drop a thousand rpm, you won't be completely out of your powerband. For me that happens to be 6500rpm. For a 2.5 liter subaru with a small turbo 4k-4500 would probably be enough.

Thanks for the feedback. I use to drive an '06 but I just recently traded in for an 09. It has 1200 miles.
Anyone think that burning the clutch hard enough for a puff of smoke to come from the clutch would've glazed it? Or cause sever damage?
Should launching a new car with less than 1500 miles be ok?
Sorry to sound repetative. I ended up doing it again. Another puff of smoke. The gas pedal feel is just too sensitive in the 09 compared to the 06. Anyone have this problem in the 09?

You will probably be okay for a few launches (10-20?), but if puffs of smoke are coming out your clutch won't last that long. With myy stock clutch, I dropped it the first time at the track and just sat there spinning the clutch, given it's a different car, but probably comparable strength on clutches. The worst that will probably happen is you just won't be able to get on it in a higher gear without the clutch slipping (more torque to the driveline) and that would be your signal to upgrade the clutch. I am sure they designed the clutch to slip in the event somebody decided to do what you are to spare the driveline.
