This is the best one I know of; play around the site some too, they have some neat tools there. You will need to know the specs of your vehicle to enter. Such as transmission ratio and tire diameter for example. Remember that it is only theoretical. It assumes your motor will never overheat and that you have unlimited battery current available. In the real world there are strict limitations on both. You have to be reasonable with the expectations; I would start gearing it around 30mph at first. If I felt it needed more speed, and it was not running too hot, then I would go up in pinion size to gain more speed.
