I had a thought this fine morning ( plus 40 degrees in two days !) about a/c .
Probably like half the club , i have a few ac cars . When the time comes for restoration one faces a real mess - try to do rebuild to use huge bucks , essentially illegal R-12 , or “ just as good” (?) subs, do nothing and hope with R 12 , or convert old system to the new refrigerant . System is open anyway when restoring ..easy to do stuff correctly then. I have never gotten a straight technical story ( just opinion and anecdote) about whether our expansion valve based system ( the valve itself) works well with another refrigerant , but all are throttling valves that close when temp is low enough , like thirties , , and progressively open while still throttling for more expansion volume if core temp rises . So from basic operation it ought to work .
The RV2 compressor was always a bit of a dog imho - seal leaks clutch stuff / variations , reed valves etc. Kind of crude heavy and large . But if thoroughly cleaned out our evap core and condenser are generous and copper (!) , the dryer is available and large — all great stuff —
so the idea is :
maybe club works with vintage air to make a kit to put Sanden compressor on RV2 bolts? And convert correctly , correct custom hoses , possibly even adding cycling clutch type operation ? Dual belts an issue but solvable ?
market here has to be 500+ for them? I would buy instantly for an F ac I am contemplating starting . Probably cheaper than fixing the old stuff in long run, and it will work . I Was first thinking of abandoning stock and going add on vintage air , that would look awful. Which brings this up .
I have also removed 2-3 add on air from F ‘s over the years.
And I have a few restored 300 “ok” except no R 12 . So = has ac , “ just needs charging” — aka , no ac . Converting an RV2 in the car is dicey due to changing ALL oil exactly right ? And — do you rebuild RV2 (!!arrgh) —Wrong Oil is all through the system ?
Anyway , might be a zero expenditure good thing if one of us has the time. Get cadillac type powerful cold AC from a bulletproof system ? great readily available compressor cheap refrigerant cold air .No stories needed just sayin .. sounds good to me .
