DP02 engine specs
#30032 from Michael Major · Not recommended · Minutes (2021-04 Fastrack)
Thank you for your letter. The Club Racing Board does not recommend this change. Please see the response to letter #30038 in
the January 2021 Fastrack Technical Bulletin. Switching to a 2.5L engine is not the only option. Line G's notes include a lower
minimum weight for cars using a modified 2.0L engine that allows for the difference in torque compared to larger displacement
engines. The 30mm single inlet restrictor (SIR) required on Line G engines balances power with greater precision than could be
achieved by prescribing allowable parts and modifications for each engine application. A sealed SIR airbox for the DP02 is
commercially available to competitors who do not wish to build their own.
