Drag racing

Every car has its own launching method, and the techniques which are best for your car.
All you need to do is experiment with your car, and be aware of any changes to your setup, weather conditions that could change what you thought was the best method (traction)
Starting on wet surface.

Take a look at managing a manual transmission.
With a stick shift, the main aim is to avoid excessive wheelspin by pressing the throttle too much, but also avoid bogging down the motor by pressing the throttle too little.
The driver has to get the throttle input just right.
Each car engine has a different rpm range in which it will produce the most power.
The trick is to keep the engine in this sweet spot from the moment you cross the starting line all the way to the finish line, without any of this peak power being wasted.
Launching a car hard from a dead stop is accomplished by slipping the clutch and spinning the tires, both within reason.

Power is lost here, but most engines have narrow power and torque bands, so the fastest launch will include wheelspin and slipping the clutch.
The only way to find out how much slipping would be just right is to experiment at the track, holding the throttle at various rpm levels
at launch to see how much juice is needed for the quickest start. While playing with the clutch and throttle, use the parking brake to keep your car from rolling. This is the only way to keep your car stationary while you work the clutch with the left foot and the throttle with the right. You then release the parking brake as you launch. Some people may say a manual benefits from powershifting during a race, which is to keep the throttle floored between shifts. It is not a good idea for a beginner, since a ill-timed shift can cause your engine to over-rev and inflict permanent damage.

Drift racing
car while it is going sideway whether it through a corner or in a straight line the cars set up for drifting have a completly different suspension setup
compared to normal or grip racing as it is called.
In grip racing you are trying to get the car to stick to the road at the highest speed .

Drift racing as all about style and control the better you are the faster you go and the longer you can drift.
There are more drifting tehniques.
Some of my favorite:

Jump Drift- in this technique the rear tire on the inside of a turn or apex is bounced over a rumble strip to help lose traction resulting in over steer.

Kansei Drift- this is performed at race speeds, when entering a high speed corner a driver lifts his foot off the throttle while slightly turning into a corner to induce a mild over steer and then balances the drift through steering, braking and throttle motions. If car catches grip, this tehnique will not work.

Power over- entering a corner using a full throttle and producing oversteer and tail slide through a corner.

Shift Lock- Changing a shift "KICK DOWN" when entering a corner to produce over steer, releasing clutch starts starts this drift.
