USAC ANNOUCES EXPANSION OF ENGINE RULES

USAC ANNOUCES EXPANSION OF ENGINE RULES SLATED FOR WESTERN AND ROCKY MOUNTAIN SPRINTS FOR 2009

CHANGE TARGETS INCREASING COMPETITOR BASE AND REDUCING COST OF COMPETITION

The United States Auto Club announced today enhancements to engine rules for 2009 for both the USAC Western States Sprint Car Series and the Rocky Mountain Sprint Car Series based in Utah.

Starting the 2009 season, 410 cubic inch engines with certain intake restrictions to be announced will be allowed in the Western State Sprint Series. The 410 cubic engine specification currently is being utilized throughout USAC’s National Sprint cars and the USAC/CRA Sprint Series based in California. The modifications to the rules will allow National and CRA race teams can utilize the engines they use in their series to participate in the Western Pavement Sprint Series. The restriction will be announced after testing is completed to ensure equalized output of the current 360 based series. With this change, USAC CRA and Western States Competition Licenses will be one combined License.

Additionally, a new engine platform is being approved for both the Western Sprint and Rocky Mountain Series. The optional new all-aluminum Chevrolet LS3 based engine is a sealed application offering a 12-1 compression and 7400 RPM Rev Limiter. USAC testing has proven the application to be competitive and reliable, with a cost of $14,000. A single source for this approved sealed application is Schwanke Engines (see contact information below).

All other engine rules will still apply for 360 cubic inch engines as well as 410 cubic inch engines legal for National use.
