The track will supply the competitor with a new, factory sealed engine in direct exchange for the competitors ‘as raced’ engine. If the competitor fails to comply with the claim request, the competitor will be excluded from participating for one year and will forfeit all points acquired to date. The same will apply if a claimed engine is found to be blatantly illegal.
