Recognizing the fact that the Ford GTs are walking away from their GT Le Mans competition, IMSA has broken from its standard rules requiring a two-week notification for making Balance of Performance (BoP) changes by issuing an emergency order for BoP changes to take place before this weekend’s running at the Canadian Tire Motorsport Park.
Racer.com explained the changes following Tuesday’s technical bulletin as well as the IMSA rules in making these BoP changes during the week of a race:
“Due to the atypical shortage of days between the Watkins Glen and Canadian Tire Motorsport Park Events, IMSA is exercising Article 2.2.2. (language below) to enable a change to the IWSC CTMP Balance of Performance Tables outside the standard notification timeline listed in Attachment 2, Paragraph 2.4. of the IWSC Sporting Regulations and SSR.
“2.2.2. Principal Rule. On occasion, circumstances are presented, either unforeseen or otherwise extraordinary, in which strict application of the rules may not achieve the Purpose. In such rare circumstances, Officials, as a practical matter, may make a determination that is not contemplated by or is inconsistent with the rules. Such determinations are reviewable by the Supervisory Officials. All such determinations are Conclusive, except as provided for in the rules.”
As IMSA has recognized the currently existing imbalance of performance between the turbo-powered Ford GTs and the rest of the field, the following changes to BoP have been made:
Corvette Racing will receive a reduction of 10 kilos (22 lbs) and the air restrictor receive a 0.4 mm wider opening. The C7.R also receives a 2 liter fuel increase to compensate for the additional fuel consumption.
The Porsche 911 RSR receives a reduction of 10 kilos (22 lbs). Ferrari 488 receives a 1 liter fuel increase. No changes to the BMW M6.
The Ford GT gets an extra 15 kilos (33 lbs) weight and will have power and torque reductions through turbo boost changes from 2000-7200 rpms.
We’ll see if the emergency changes by IMSA result in a more level playing field later this week. The first practice sessions for the WeatherTech SportsCar Championship at CTMP is Friday.
