I'm not a 2 Club member but I thought I'd add a couple of things that might also bear consideration.
The SCTA-BNI "I" engine class covers 750 to 1000cc's, but the FIA groups (A-I-5 and A-II-5) are for 750 to 1100cc. So would somebody running the Shootout with a 1070cc engine be held to the "I" or "H" SCTA-BNI minimum?
The SCTA-BNI "E" class (3000 to 4276) doesn't align with FIA A-I/II-9 (3000 to 4000). Would any 4-liter FIA records have to exceed the SCTA-BNI minimum for 4.276?
FIA A-I/II-10 (4000 to 6000) doesn't match SCTA-BNI C/D, either
FIA also has separate groups for rotary (i.e. Wankel) engines. How will those be handled?
Then, there's turbine (wheel-driven), electric, and steam. Both FIA and SCTA-BNI assign these classes based on weight, but they're all different: only 3 classes each for SCTA-BNI, but FIA has 11.
FIA has hybrid and solar, too, but not SCTA-BNI.
DW: I just thought I've give you something to ponder to keep you out of mischief!
