[Diy_efi] Intercooled question

[Ron Schroeder]

Hi Lyndon,

If you are talking about automotive A/C, R134a is not a very good substitute
for R12 in an A/C designed for R12.  Even if the seals and the oil is
changed, the C/R of the compressor is not correct for R134a in most old
systems.  There are a number of retrofit substitutes for R12 in A/C units
that are far better than R134a.  (R134a is fine in units designed for it)

As a phase change coolant for an intercooler, I think there are better
choices than either R12 or R134a.  Especially if there is a chance of not
full recovery of the coolant.
