Great answers above, and in addition - depending on your car, there is likely a web based forum dedicated to it, much as this one is for the empeg. And on such forums, there's almost always a section where people discuss racing, techniques, etc. If you want the fastest acceleration, read up on the experiences that other owners have at the track, and go from there. They have likely figured it out already with many actual runs, and it will probably be similar to but not the same as what you calculate or expect.
