Rules are meaningless, if they are not consistently enforced.

As a racer, you must insist on proper rules enforcement.  RACESAVER®  is fortunate to have the high character and unselfish efforts of our regional directors and tech men. Our full technical support is available to every region. How passionately racers support their tech officials, determines how fair racing will be in their region. RACESAVER®  rules were specifically created to protect the little guy  from the few slickey boys who will spend unlimited money to cheat a win. Fight back!  Insist on consistent   RACESAVER®   rules application.

RACESAVER®  Sprint Series sanctions regional groups who utilize these 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. 2008 will mark the 10th 305 Nationals (sm) running under  RACESAVER® Sprint Series sanction.

Preventing racers from spending their last dollar is nearly impossible, but,  RACESAVER®  rules, nationally proven through twelve 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®  305 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.

Objectives:
This is recreational racing. Safety and cost containment are our objectives. Respect, for competitors, fans, and promoters, is fundamental to our success.
