Currently, a standard 25% is used when no actual data is present. Other percentages are used when there is supporting documentation and ITAC members are willing to put there names next to the data.
So Andy, why is the 300zx in ITS at a 30% multiplier? It is not a 4 valve car, nor is there any indication that the 30% is correct based on measured amounts. Or if there are cars that were measured I'd be curiuos to talk to the guys that own these cars.

This is aimed at the point that the process is not transparent, never has been, it has always been subjective. The difference is that now not only is it not only not transparent but it appears that the CRB isn't bothering to listen to what the members are asking for.

But on the other hand in the northeast there are few choices on who to go racing with. So in March we'll pay our entry fees and continue to show up and go race. What else are we to do. In two years we'll bring our HANS devices.
