Adjustments from on track data
Both the ad hoc committee and the crb know adustments may be needed. This was never set in stone.......but we need good data to make informed decisions.
We will have the opportunity next year to compare the Kaw and GXSR in the SAME CHASSIS. There will be at least one Phoenix with a Kaw, and probably a JDR. Both can be at min weight with the kaw.
If we look at acceleration data from a slow roll to top speeds seen at faster race tracks...say 50 to 140 or so....in the same chassis.....with the same wing settings and near same weight......that will be useful in making an adjustment if needed.
We just can't compare data from two different chassis.....with totally different drag and weight. Also, we can't just look at top speed.....or acceleration up to something less than to speed. we have to look at acceleration over the entire speed range.
It will probably take a full season to gather enough data.....but it is imperative we do so.
Until we have that data, the restrictor sizes recommended by the ad hoc committee are a very good starting point......and are based on very good analysis of lost of dyno data, gear ratios in the different engines, rpm operating range, etc.
