a. In an empty parking lot, or somewhere desolate, put one foot down HARD on the brake pedal and then slowly apply the gas pedal until the rpms come up and stop rising. that is the stall speed that I will refer to later.
b. write this number down, mark it on your guage face with a non permanent marker, or memorize the needles position. you will need this later.

2. Practice.
a. Using the 2 foot technique (one on gas and one on brake) determine the amount of brake pedal pressure needed to hold the car in place with the engine at the stall RPM.
b. Now with your foot on the brake with the needed amount of pressure slowly raise the engine RPM to the stall, then drop back from the stall by 200 RPM.
c. Finally, this is the tricky part where you need cordination. Release the brake pedal WHILE mashing the gas. the 2 actions have to happen at the same time, if you bounce off the stall your launch is ruined.

3. Experiment
a. Find at what engine rpm you feel like you get the best launch from. different cars with different mods have different power bands. some may launch the best right at stall while others may do better several hundred rpm below stall.
can you do a video DYI? thanks
