The three significant areas of refinement to the methodology are:
- The amount of change (ie. increase/decrease) in the turbo boost pressure adjustment will be reduced from the current level
- Boost adjustments will be applied to either individual drivers or teams – yet to be determined – but not per car type/chassis as in 2012
- The frequency in which the adjustments are calculated is also to be finalised – currently it is a ‘rolling two-event’ average
BTCC Series Director Alan Gow commented: “As with almost any regulation, particularly new ones, they are ‘tweaked’ based on experience gained – and that’s exactly what we are doing here. As well, with S2000 cars now not having strict performance parity, the baseline boost levels on NGTC cars can increase and thus the profile of the calculation can alter.
“All the teams endorsed that the fundamental aspect of using the lap time analysis was the right way to go, but that we should refine those three areas in particular. In the coming weeks a working group, comprising a representative cross-section of the teams, will finalise those exact details.”
The baseline boost levels for each car/engine will again be calculated and set prior to 2013’s opening round, aided also by the huge amount of related data which was collated during the 2012 season.
