there is another way to launch on automatics. i think its called power braking but w-e. you press down on the brake just enough, then step on the throttle. your toruqe distrubiter should start to slip.but your not saposed to do it to long or you will over heat it.
eh, that's pretty close. 1. it's a torque converter....the name "torque distributor" would fit, but anyways. actually pressing the gas until the wheels spin and then letting off the brakes will only net you more wheel spin. because while you're sitting there with your foot on the brake spinning the tires...you've got the brakes applied. as soon as you let off the brakes the tires are going to spin that much faster. and as we all know wheelspin is fun for a smoke show, but bad for a time-shaving launch.
ideally you want to hold your foot on the brake and foot on the gas right at the point of your rear tires breaking loose, but not actually starting to spin. which is why some people use a higher stall converter. it slips up until a certain point...allowing the rpm of the engine to become higher before your tires start spinning. higher you are in the rpm band the more power you put down to the ground sooner. allows you take off like a bat out of hell compared to a converter with a lower stall point
and yes, while you're sitting there "power braking" and the wheels aren't spinning, the fluid in the converter is getting hotter and hotter. which is killer on the fluid, which brings even more heat to the transmission, and heat is the major killer in automatic transmissions.
