P1 Sealed 2.0L Engines
#28400 from Michael Major · No action required · Minutes (2020-03 Fastrack)
Thank you for your letter. Competitors have always had the ability to choose between running a DP02-
spec sealed 2.0L engine without an inlet restrictor under Line F or an unsealed 2.0L engine with a 30mm
SIR under Line G. Delaying the previously announced sunset date for the DP02-spec sealed engine
option until 1/1/2021 does not affect a competitor's ability to run an unsealed 2.0L engine during the
2020 season.
