                                              2007 Rules
                       Here is the proven RaceSaver® plan:

Stable and Enforceable Rules, Consistent Rules Application, Fair Purse Distribution

Did you know that the average sprint car purse pays the winner 10 to 20 times the amount earned by the 24th place car? Races run under RaceSaver® plan pay the 24th starter at least 1/2 of the winner's purse. A typical RaceSaver® purse would pay the winner between $250 to $500 and the 24th starter $125 to $250. No, that isn't a lot of money but that is exactly the plan. Big money brings big problems. You can be competitive for under $150 per night. Now you can race, pay the mortgage, and send the kids to school.

The RACESAVER® Sprint Series sanctions regional groups who utilize the RACESAVER® Spec rules. We maintain a master technical file on every RACESAVER® 305 Spec head. This supports each regions technical staff, enabling common rules compliance throughout the series. 2007 will mark the 9th 305 Nationals (sm) running under the RACESAVER® Sprint Series sanction.

The RACESAVER® Sprint Series encourages affordable Sprint Car Racing. A competent race car, utilizing a 1 year old rolling chassis and a new engine can be on the track for around $10,000. The engine operates in the 6500 rpm range and produces 400 to 425 hp. It can utilize lower cost components and still have excellent durability. Most of these engines race 3 or more seasons without an overhaul.

Since it is impossible to prevent racers from spending money, RACESAVER® Spec rules prevent money from buying a significant advantage. These proven rules are the result of considerable research and 10 successful years of racing. TheRACESAVER® 305 Spec head, made to our specifications is the foundation of our rules. We keep gauged, inspected and serial numbered heads in stock. Ten full seasons of hard racing, and over a 7000 dyno pulls, have proved the RACESAVER® Spec engine rules beyond any doubt. All engines must be sealed before they are allowed to compete. The engine must be drilled for sealing wire on: 2 adjacent cylinder head bolts on each head, 2 intake bolts, and 2 timing cover bolts. All logo and trademark stamps must be intact at time of inspection.
