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 9 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 6000 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.

This is recreational racing. Cost containment is our primary objective. Respect, for competitors, fans, and promoters, is fundamental to our success.

The willingness to give racing room is a defining aspect of RACESAVER® Sprint Series races.
