Attention Car Owners:

As discussed at the Spring 2011 General Meeting, in attempt to prolong engine life and preserve the level of competition in ARDC, the Board of Governors has agreed that the following RPM limits will be enforced in 2012:

All pushrod engines (166ci):        8500 RPM
All Overhead Cam engines (155ci):            9500 RPM

Please note that 2012 is the final year in which Esslinger’s “TST Head” will be legal. Starting in 2013, the 155 Esslinger will only be legal with the “ST Head,” making the XT, TXT, and TST heads illegal.  It also important to recognize that OHC engines (whether iron block or aluminum block) may not exceed 155ci.

UPCOMING EVENT: ARDC Season Opener, Big Diamond Speedway on Saturday, April 07, 2012...
