The result:
That's at idle. Moving down the road, the vent temp drops to about 37/38*.
The A/C compressor came with my motor, so the components that I had to buy are:
A/C Belt 19.31
Evaporator 69
Condenser 57
Hard Lines 71.19
Drier 12.99
Switch Port 5.2
Fittings/Hose 114.95
Misc (bolts/sheet metal/etc) 20.18
O-rings 5.44
PAG oil 8.99
134a 24.98
Total: $409.23
So, was it worth it?
It works pretty well. We've had a few days in the high 90s lately and the A/C has kept me comfortable but it didn't turn it down, either. I think it could use a larger condenser and evaporator, but, for the price, I'd do it again.
