Last night at the track I found that with my HF (ha ha ha 53wHP - 85 lbs/ft TQ) I launch just under that rev limiter. You see I do this by staging and then finding the rev limiter very quicky. Than I pull about 500 rmp off of that total drop the clutch and ride the spin till I bog down - the whole time keeping the beast floored. Of course the rev limiter doesnt always work on my car for some reason so I usually just launch around 5000rpm. This nets about a 2.6 - 2.7 60 time. Not bad for a 19.5 second car! 
The launch is where its at to get marvelous times like that!

I had a older turbo Probe Gt years ago (fwd). I would hold the r.p.m.s at about 2500 - 3000 and would let the clutch out about 3/4 on the way when the light dropped. Then I would let out the rest of the clutch depending on the launch / tire spin. This is basically what everyone else has mentioned here. Tire psi. is critical as Mr. Self Destruct noted. Dont go to low though because that will work against you by having the sidewall of the tires being to soft. It will also cause your car to walk around on the track at the top end not to mention to low of a tire p.s.i. = more rolling resistance which equals a little less e.t. and trap speed.

and when i launch i stay steady at 2200 rpms then nail the fucking gas. by the time i get done doing what minor spinning i do i am already into v-tec and rocking someones world
