Wolf or Norma with 1.6T allowed in P1?
#33097 from Steve Marton · No action required · Minutes (2022-10 Fastrack)
Thank you for your letter. The P1 rules state that "Engines not specified in the table below are not permitted in P1." No spec line
in the referenced engine table permits a turbocharged engine by engine series or requires a Turbo Inlet Restrictor (TIR). Please
see GCR section 9.1.8.B.J.4 and the P1 Engine Table. Forced induction engines are outside the class philosophy. Please see the
responses to letter #28809 in the June 2020 and September 2020 Fastrack Minutes and the response to letter #33123 in this
Fastrack's Technical Bulletin.
