Weights and Engine Allowances
Minimum weights for cars with normally aspirated piston engines will
be determined by 1.1 lbs/cc displacement for the installed engine (see
following table). Displacement is the factory displacement for the installed
engine. For
the purpose of weight assign ment, engine displacement will
be rounded to the nearest 100cc (e.g., 2150cc = 2200cc
and 2149cc
= 2100cc).
Correct, but the rule specifially states "for the purposes of weight assignment".
it does not say that calulation is to be used for engine displacement eligibilty.
Reading the proposed rule strictly, "up to 3.2L" = 3200cc.
So the question then is what is the 3.2l cutoff? Is up to 3200 actual cc the ceiling for eligibility, or is 3200 calculated cc the cutoff? If the latter, the limit is really 3.249 litres, not 3.2litres.
The wording also says "displacement is the factory displacement". 3246cc is greater than 3.2l
for example: 5.0l (old old trans am limit) - Ford 302, Chevy 305. "5.0l" engines, but both were under the 5000cc limit.
I guess my point is the actual displacement limit should be clarified, assuming the proposed rule is adopted.
