Topic: Hot Idler Compensator

[ChrisV289]

How early were these installed on Mustangs?  And is it something judges should be looking for when judging a car that has AC?  I don't show it listed on the judging sheets.

Sorry to bring this topic up again but would like to know if a factory AC car built in Oct 64 should have one of these installed?  Also if these were installed on factory cars should the judging sheets/rules indicate this?

I would say yes you should probably have it on yours.

Page 8-72 of the 67 shop manual has the compensator pictured in the PCV hose. (figure 28)  It is labeled as "non-thermactor A/C 289 (2-V) models only".   Not sure if the 65 - 66 manuals have similar information,  But I know some of the 4100 4-V carbs in 66 had built in compensator on rear of air horn.  The 66 4100 carbs with compensator were for emissions equipped cars (California)

So apparently both A/C and or thermactor determined if compensator was present, but am unclear exactly how the rule was applied.  AM curious if the 66 manual shows compensator in the PCV hose for 2-V carbs?
