Rulebook 1.H. What's the SCTA airpump?

["Matt Ferrari" <market@gammasports.com>]

Hello, everyone.



Rule 1.H states that any engine that cannot be measured using the S.C.T.A.
air pump or special tools will require disassembly for direct measurement of
cubic inch displacement.  I'm going to be within the engine class
requirements, but I'd rather avoid pulling the heads if I can (DOHC).  What
is the air pump or other tools that are used to measure displacement?  Do
you have any suggestions to make the measuring easier for the judges?



Thanks in advance,



Matt Ferrari
