I have not street raced in over 11 years. Is there a simple "type" equation for figuring car lengths as relates to 1/4 e/t's. In other words if one car runs 12.0's and another 11.5's how many cars would the 12 car need to beat or break even. Or say a 13.0 car against a 11.0 car etc.... Just curious because I dont plan to street race, but if a something comes up just wont to be prepared and not get burnt.
