    New rules allow an 18-71. Does anyone have any knowledge of what we would gain in performance?

    The trend in Radial vs the World cars has been back to high end 14-71's instead of 18-71's because the rotor is so long in the 18 that it is harder to control the twist and keep the tolerances tighter.
