Elan DP02 Restrictor
#30138 from Aaron Hill · Not recommended · Minutes (2021-04 Fastrack)
Thank you for your letter. The Club Racing Board does not recommend this change. The sealed DP02-spec 2.0L engine is outside
the P1 performance envelope. Please see the responses to letters #26753 in the July 2019 Fastrack Technical Bulletin, #27867 in
the January 2020 Fastrack Minutes, #29756 in the December 2020 Fastrack Minutes, #30038 in the January 2021 Fastrack
Technical Bulletin, and #30032 in this Fastrack. A restrictor is not being added to modified DP02 engines for 2021. Modified
engines have been required to use a single inlet restrictor since the class was inaugurated in 2014.
