In my eyes it is all about clutch and throttle control (something that not everyone can do well - although we all think we can).... assuming you are doing it all manually. The better you can do both in harmony, the better your launch can be unaided.
A car will naturally "bog", i.e. the revs drop, if you don't get on the gas well as you start to dis-engage the clutch. Slipping the clutch will help as I'm sure you are aware, and will not require monster revs. Obviously the harder the clutch or the "on" and "off" nature of the clutch, then the harder this can be to achieve.
I could quite comfortably launch my old 500+bhp Spec C with just over 4k revs, cleanly and every time, even with a twin plate clutch. When I was playing at the drag stuff with the standard engine at 370bhp, I could attain a 1.6s to 60ft time using the same method more often than not in the latter part of those dragging days. All of this without the need for LC.
The OP has a standardish car, going by his car profile, so I would suggest that with a bit more clutch and throttle control practice he should have fewer problems without the need for mega revs.

What's the minimum revs you can use to simply get a fast start, say in a traffic light grand prix against a 2wd car with similar power (mine's a 300bhp ish bug WRX with a hybrid TD04, so not bif power but it comes in early). 3000revs?
