FB Engines and Transmissions in FA
#30099 from Michael Holland · No action required · Minutes (2021-02 Fastrack)
Thank you for your letter. The FA rules provide that engines shall be derived from automobiles unless otherwise specified in the
tables that follow. Please see GCR section 9.1.1.A.2.a. Table 2 specifically states that motorcycle-based 4-cycle engines up to
1000cc may be used in F1000 cars competing in the FA class. The FA rules also state that no more than five forward speeds and
an operational reverse gear shall be used unless otherwise noted in Table 2 that follows. Please see GCR section 9.1.1.A.3.a.
Table 2 states that F1000 cars competing in the FA class must comply with the December 2019 GCR Formula 1000 (FB)
preparation rules, which specifically permit the use of a motorcycle engine's associated sequential transmission and state that a
reverse gear is not required. The F1000 car is properly classified in the FA class.
