Assisted Shifting in Prototype 2
#29852 from John Gyann · Not recommended · Minutes (2021-01 Fastrack)
Thank you for your letter. The Club Racing Board does not recommend this change. CN cars use assisted shifting in their original
series, the V de V Challenge Endurance Proto. The intent of the CN spec line is to allow the cars to run in P2 as they ran in the V
de V championship, and to control their performance in P2 with an appropriately-sized flat plate intake restrictor, as determined
by acceleration rate data. The Club Racing Board has made such an adjustment to the CN car's intake restrictor effective 01-01-
2021 and will continue to monitor class performance during the 2021 season. Please see the responses to letter #29822 in the
December 2020 Fastrack Technical Bulletin and letter #28072 in the March 2020 Fastrack Minutes.
