@CenturyOldRacer It’s actually 17.2 to 1 if you want to get technical. It needs 116 octane race gasoline or higher. I have been running Renegade 120+ and it works well. We found that every point of compression increase raised the horsepower about 4 percent without making any other change. So naturally I wanted the most mechanical compression possible, and 17.2 was the absolute limit and still have everything clear like the intake valves for example
