"Custom" A/C Compressor....

Recommended Posts

1987 2.5L base 944 coupe:

 

Wondering if anyone has seen this type of install for an A/C compressor-

 

In May the Las Vegas Region PCA (LVRPCA) arranged for members to receive an assessment of their car compliments of Trophy Performance.  After getting the car on the lift and raised the first thing the mechanic pointed out to me was, "I don't know what that A/C compressor is supposed to go into, but it isn't a Porsche 944."  Another mechanic confirmed his observation.  The accessory drive belt (crank pulley, AC, alternator) is also longer than the OEM belt and about 1/3 the width.  The compressor has four sets of 'ear-lobes' compared to the two sets of an OEM compressor*.  The AC lines also install at the rear of the compressor, rather than in between the two upper ear-lobes.  Rather than mount the two upper ear-lobes to the points an OEM compressor would mount, it is instead mounted to two brackets (two bolts per bracket), which is in turn mounted to the normal mounting position of an OEM

 

I've attached some pictures:

-Red 'star-dots' locate the extra mounting brackets

-Green locate where the non-standard compressor mounted to the extra brackets

-Yellow show the mounting position of a OEM compressor

-Blue shows where the tensioning bar mounts on the lower ear lobe. 

 

-A red square shows where one of the ear lobes rest on the sway bar (torsion bar?) and has began rubbing a divot in it

-A yellow circle shows the ear lobe that was ground down.  I am assuming this was an attempt to pivot the compressor toward the engine block to allow the fitting of the drive belt.  Because of the inclusion of the two mounting brackets, it won't work with a correct belt.  Instead they used a much longer belt that is also approximately 1/3 less the width of a correct belt.

-Blue circle marks where the AC lines mount on an OEM compressor

 

So has anyone ever seen something similar to this 'customization'?  I'm really curios if this was an aftermarket kit that was once offered for the 944.

Finaly found something on Google:

 

An online supplier list a conversion kit that has the brackets, hoses, bolts.
