Working with Oil Windage
This chart shows how oil levels can affect power. Using the stock pandesigned to hold 4 quarts (so the system total is 5 quarts when thefilter is included), we varied the oil levels to see how power wasaffected. As you can see, more oil created more windage problems.Unfortunately, 5 quarts is often too little oil to properly protect theengine under racing conditions. The oil is too easily overheated, andthe potential for the oil pump to completely drain the pan is too high.Racing pans are normally designed to hold more oil so that this doesn'thappen. Both the Champ pans we used are designed to hold at least 7quarts of oil. (For the sake of consistency, we used 5 quarts of oil asour baseline in all our tests no matter what pan we used.)
