was asked to repost: Texas BusFest Valve Cover Racing Association (TBFVCRA) “Official” rules. • Cars will be built using an actual rocker cover from a VW engine; steel and or aluminum are allowed. • No engines or propulsion of any kind save gravity. • No moving weights/counter weights. • Wheels can be attached to the car in any manner, but must not extend beyond the front or rear of the valve cover. • Nothing can extend beyond the front or rear of the valve cover. • Cars will have at least four wheels, each no more than six inches in diameter. • Wheel must have a non-metallic surface contacting the track. • 10 inch maximum overall width. ^^ • 10 inch maximum overall height. ^^ • 8 pounds maximum weight. ** • Valve covers will be clean (no sludge or oil). If the racer drips oil or grease, it is disqualified! Rules of the track and race are as follows: • The judge's decision is final. • The track will consist of two lanes with each lane being 18 inches wide. • If a racer (person) interferes with another car, it (they) automatically lose that round. • If a racer is hampered by a track issue, it will get another run. • If there is a tech issue, the judge's decision is final. • “official” rules are subject to change. ** official scales have been tested using state of the art weights and measures designed and operated by qualified NASA space engineers. ^^ Official height and width will be measured using an old yard stick.
