First, we have to do some testing. The reference high and low compression motors have been built, but they need to get into cars, be broken in, and dyno tested. There are lots of potential options for this, and as of now, they are all possible:
1. Weight adjustment
2. Spec Chip/DME for the LC cars
3. Offset cam key for the LC cars
4. Restrictor plate for the HC cars
My preference is to give the LC cars a small allowance, rather than to slow the HC cars down, BUT this has to be able to be done in a cost effective manner. Until we do some testing to see what works, and at what cost, it's all speculation, and could go either way.
