footbrake racers
Depends on a whole lot of factors.... It's more of a "play with it until you find the sweet spot". My Challenger would like to be foot braked up to 1500, then mash the gas on the 3rd yellow... But my father's Pro Street Valiant likes to leave the line off idle...
Just find a good air pressure in your tires, then play with different RPM's at the track. It doesn't take long to find the area where it likes to "spin" or "hook"
