Thanks Stephen

*I have spoken to the engineers, reached cam specs and this is what i have come up with:

Road Car:


duration 269 / 260
duration 235 / 226
maximum lift 11.50 / 11.00mm
lift at TDC 0.30 / 1.40mm

2000-6500RPM
application sport

Rally Cross:

duration 293 / 285
duration 259 / 251
maximum lift 13.00 / 12.50mm
lift at TDC 4.30 / 3.80mm

4500-8500RPM minimumCR12/1, race exhaust system needed.
application rally & race

*So now I am going to attempt to manufacture a fine line between, but this will purely be an experiment.

*As for the valves im getting them spiraled and ported with the technology of a C63 AMG

This should create a significant increase to just the head work...bottom end to go?
