SKUSA Claims Engine at Phoenix SpringNationals
Written by John Motley - National Tech Director   
Friday, 18 May 2018 21:44
At our recent SpringNationals, SKUSA exercised its option to claim a competitor’s engine. We have done so periodically to insure that there are no special or outstanding engines, or any unauthorized modifications that require additional inspection not available at the race. IAME engines used in SKUSA competition are remarkably identical, reflecting the high quality and manufacturing ability of IAME. However, the perception exists of special or significantly better performing engines. To refute this, we intend to exercise our option to claim engines from time to time. Note that the engine claimed met all applicable SKUSA rules and was replaced at the event with a complete new engine package as well as a check for $500, as SKUSA rules provide.
