Griffith's Complete AC System Test Results
 
Since it was hot (for here, close to a record) today 100-104F depending on where you were standing in the shade I thought I would give my new Griffiths AC system a test.

The temp. measurements were made with a Traceable thermometer.

Griffiths Upgrade(s): new evaporator and front condenser, all new hoses, new thermostat and compressor (same model as stock R12). I added both rear fender condensers and the variable speed control system for the evap. fan. The only not new part was the deck lid condenser which I had flushed at a local place. The fluid is 134a, installed 36 fl. oz and 6 oz. of DEC PAG 46.

Results: Time 2:00 PM, outside temp let's say 102F, vent temp. 40-44F. This was at ~40mph in 3rd with the temp. turned all the way down and the fan speed at ~75%. Inside was comfortable and cool without the vent blowing directly on me.

Installing all the parts/etc. is a good chunk of work. However, it is nice to drive the car anytime now and be comfortable.

Holy spal fans, Batman.
An A/C system that actually works!
May the microchannels be with you and the snake oil be always on your boots....

(Good job!)

That's pretty damn good! Congrats.

And of course I didn't upgrade mine and had to live without through our toasty summer, eh Bill?

One month ago I did a similar upgrade to my 1987, except I used R12 freon. I live in Augusta ga and 95-100 degree days are common in the summer. I did a similar test during a 95 degree day and it blew 28 degrees at the vent. I know r12 is difficult if not impossible to get in certain parts of the country but if you can get it use it, you will not be disappointed

Reverse osmosis coupled with the bathtub displacement principal.

Haven't had too much seat time this year in the SC but have at least burnt through most of a tank of fuel this summer.
My R-12 system is flat at this time but I may know a guy......

Was a hot year here and I have been running the home AC on a regular basis.
