As previously announced, IndyCar is allowing in mid-June and again at the end of the season for manufacturers whose engines are statistically more than 2.5 percent deficient in power to request approval of improvements to components. to be homologated. The series also announced a procedural change for Race Control to avoid a repeat of the situation that resulted in an errant penalty for Scott Dixon at Milwaukee last week.
Engine alterations are allowed to make up 2 percent of shortcomings, and they will be introduced on only new engines being sent to the track. Manufacturers must present data to support their case, which is reviewed with relevant data collected by the sanctioning body's engine support engineers. Manufacturers provide which components they seek to modify, along with projected gains and their scheduled introduction. IndyCar will permit all, some or none of the proposals and the manufacturer may revise its plans accordingly.
Once approved, IndyCar will inform the other manufacturers which components are being changed. The new parts will be homologated (sealed) before being incorporated, and the old parts remain homologated until the 2013 homologation date. For end-of-season upgrades, work must be completed and homologated before the first race of 2013.
The engine rules will be stable through the 2016 IZOD IndyCar Series season, with any corrections or modifications decided by IndyCar after consultation with the IndyCar Engine Committee.
With regard to restarts, IZOD IndyCar Series Race Director Beaux Barfield said a video camera will be fixed on the starter from now on to capture the green flag on starts and restarts, which will be recorded on a DVR and automatically synchronized to the other video in the system, eliminating the need to manually sync to Timing & Scoring.
"It unquestionably improves our ability to precisely officiate starts and restarts," Barfield said.
