ideal launch...
In short, there is no ideal rpm. It depends greatly upon road conditions, and car mods.
Ideally, you'd launch hard enough to get just a little squawk out of your tires. Then accelerate hard enough to be on the verge of spinning the whole time. That ideal launch rpm will change as temperature, weather, road surface, tires, engine power output, and drivetrain component strength change.
A cold, wet day on asphalt on crappy stock tires, and the ideal launch rpm will be pretty low. Warm, dry day at the track with drag radials or slicks and a few power mods, and you can launch pretty high, as long as your clutch and tranny can take it.

i beleive that if you want to perfect your launch the best way to train is in the rain
if you could find a safe spot to pactice, over time you will find that you could almost launch at any rpm wether the ground is wet or dry or if you have good tread or bald a$$ tires. yes better tires on dry ground will give best results but thats if you know how to launch, by practicing in the rain or just on a wet surface you will master your launch in no time . reason why is because its really all about the way you work the clutch.
practicing in the rain gives you the opportunity to get a better feel of your clutch and your tires working together .
in the ra , releasing the clutch to fast could have you cherping the wheels at only 1000 rpms (even on dry ground)but is that the best way? no.
releasing the clutch to fast at low rpms could cause you to hop, baug, jerk or just stall and also not supply enough power and tourqe to carry you through the gear strong.
or you could launch at lets say 3500 rpms and release the clutch very slowly without burnig any rubber at all (on wet or dry ground) but is that the right way ? no
releasing the clutch to slow at high rpms over time will put serious wear and tear on you clutch. not to mention that since your already reving at such high rpms by the time you fully lay into the gear its only a matter of seconds befor you have to shift witch could cause you to lose power into the next gear.
that being said , i found that practicing on a wet surface gave me a better feeling of control over my clutch, because it helped me find the median between the amount of throttle to the amount of pressure needed to the clutch . at this point i am able to launch my car at about 2000 to 2500 rpms on a wet or dry surface with out peeling wheels, and stay within a great power band throughout all the gears.
now , at the track ofcourse your not racing in the rain but the same rules apply only this time your able to give more throttle once you have fully engaged in to 1st.
so i stand by my theory of launching at around 2000 to 2500 rpms no matter what the conditions . the object is learnig how to lay into your clutch and to get the car in motion befor laying hard on the throttle and found that 2000 to 2500 rpms is the best starting point.
