Hello Brian,
Your AC compressor will not run with out any (or low) Freon in it. There's a
low pressure switch that detects the low pressure situation and prevents it
coming on. As far as gaining those elusive 500 hp in your 240D, the AC
compressor is free-wheeling and without the compressor locking in the hp
loss would be extremely small - I doubt you;d notice any difference at all.
As an owner of a sub-sonic 240D I am experienced at turning the fan or AC to
off when starting from a dead stop - or when I (Gasp!) might attempt to pass
someone - obviously they'd have to be going *very* slow, going downhill and
having zero traffic in the distance. It doesn't happen often. ;-)
Good luck -

Subject: [MBZ] A/C question
The A/C on my 83 240D has no freon in it. Haven't checked yet whether it
has
a big leak or whether it was allowed to discharge over a long period of
time
by the PO.
Question is: Does running the thing without any freon in the system harm
the
compressor?
Also: How much benefit do y'all think I'd get from removing the A/C belt
(in
terms of fuel mileage and power)? Yes, I mentioned the terms 240D and
power
in the same email. Restrain yourselves.
Brian
83 240D
