Every year one of my father's friend has a hot wheel race. We run a stock, outlaw and rocket class. The outlaw class is anything goes except rocket engines. So I was wondering if you guys had any ideas of ways to make a car faster than just weight. Last year I mounted a magnet on the back of a milk delivery van and the held up a opposite charged magnet to give it a jump off the line. Any and all ideas welcome even if they are a bit crazy. Thanks guys.
