Heads up racing: Is the best way to run, but without limiting the horsepower or the size of the tire. Thnig is to put four categories, one for 8 seconds, one for 9 seconds, a 10 s and 11.
That way if you don't have the Money to run 8 seconds you can run 10 seconds. In every heads up start your car would have to keep low 10 seconds and you need to have a good reaction to win the category of 10 seconds because if you drop to 9 seconds, cars competing in nine seconds will be in nine seconds low and your 10 second car won”t have a chance. This way, you have four categories, four winners, each preparing his car and invest whatever they can, and include more cars the day of competition. That's how we race over here in Peru
