Rules are meaningless, if they are not consistently enforced. RACESAVER® participants must insist on proper rules enforcement.  We are fortunate to have have dedicated regional directors and tech men. Our full technical support is available to every region. Passionate racers, supporting their tech officials, are the bedrock of rules enforcement. Our rules were specifically created to protect competitors who race by the rules. RACESAVER® rules will prevail.

RACESAVER®  Sprint Series sanctions regional groups who utilize these rules. We maintain master technical files on every  RACESAVER® head. This supports each regions technical staff, enabling common rules compliance throughout the Nation. 2010 will mark the 12 th  annual RACESAVER® Nationals.

Preventing racers from spending their last dollar is nearly impossible, but,  RACESAVER®  rules, nationally proven through 13 years of hard racing, make it harder for money to buy a win. You can build a competitive engine for less than $5000. We have documented proof of RACESAVER®  engines producing over 435 hp. using unmodified stock rods, crank, and cast pistons. These engines have raced 3 or more seasons without an overhaul or failure. The RACESAVER®  Spec head,  is the foundation of our rules. We keep heads in stock. All engines must be sealed before they are allowed to compete. The bolts 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.
