So when are you going to show all of us naysayers that your set-up performs at least as good as the obsolete options? From what you've shown so far, you're not even close . . .

The true test of an a/c system is how fast it can bring down an overheated cabin atmosphere to a sensible human comfort level, not how cold the outflow might be with minimum airflow once the cabin is comfortable.

bingo

try it and test it

Bob, what's hilarious about this is how close you are with those numbers - I sheet you not.

For example, I keep my personal space(s) at home very cold and do so like so:

1) in my bedroom = an 8000 btu window unit which I temperature control with a refrigeration gadget (an electronic controller that overrides the digital thermostat by way of a temp probe heater and prevents evaporator freeze-up by utilizing a frost sensor) - the low last night was in the mid-upper 60s with ungodly humidity, and my room temperature was a most excellent 52 = Heaven!

2) my small, computer room/office/study (aka: interior man cave) = 5ooo btu window unit which I temp control by way of a toggle switch installed in place of the thermostat. The toggle switch is mounted on the end of 10 foot extension cord, so I don't even have to get out of my desk chair to toggle it off when I notice the evaporator freezing.

The above is in addition to the home's central a/c.

Getcha suuuummmmm!

Will do. Always have been a fan of pneumonia.

Ever try just kicking a leg out from under the covers?

You are not really unique...

When I go home to HOT/Humid Memphis or NE Arkansas (Tyronza) I am always struck by how COLD my relatives keep their homes. Step outside and rush to get in the car and FREEZE even more, COLD airflow directly to the face and upper body.

In contrast to the mid-fifties using window fans....

Or those hand held manually operated fans in Sunday church.

^^^ Looks kinky!

[Oh Haha]

What I see is that Ronnie's vent temp was shown to be below freezing(29degrees) whilst the OP has shown temps not that low.

I'm not an a/c guy but that is an easy way to see why some question the "new" way.

[Ronnie's.930]

^^^

Reid, rather than waste your precious energies on attempting to construct silly excuses for why I am able to demonstrate superior a/c performance with obsolete, garbage technology, perhaps you should concentrate on building a cutting edge system that actually outperforms, or even equals, the old-school components and design? Maybe with enough effort on your part, you will one day be successful at doing so?

Another thing that's funny about Reid's "sore loser", crybaby commentary above is that I am definitely not the only person here to achieve this type of performance; Griff has demonstrated it on MANY occasions, people that have installed Griff's components (like Glen/GH85Carrera, Karl, Eric/silber, and many, many others), JFairman in his Turbo (a setup almost identical to mine), ect.

* The "^^^" above was pointing at a post that KelogGes deleted after I wrote this response - not in response to Wayne's post (pretty obvious, I suppose, but wanted to note that).

Ronnies A/C test Post is BS for a lot of reasons

Ask any A/C expert,
NO Automotive A/C can run this cold on planet Earth for any length of time; it is thermodynamical impossible

You missed my earlier post on the issue. At any given instant the vent temperatures might be sub-freezing and yet not, on the average, be cold enough to freeze the condensate. The thermostatic switch itself has a fairly long time constant due to the hysteresis span, temperature at which it closes (above freezing, ~35dF?) vs temperature at which it opens(below freezing, ~32dF?). Additionally the process itself is a slow one, long time constant.

Also the infrared gun he uses; it is impossible to sense / measure air temperature
also you can adjust these to show any number you want with the adjustment

But measuring the temperature of duct walls or/and the louvers is perfectly valid, possibly even moreso than air temperature since cold soaking the duct walls would be long term constant, more of an average.

there is a lot of other things also bad about his post

calmed temperatures only on a hand gauge showing nothing else tell you nothing

My post is a real driving test; including pictures of the car driving, instruments driving, see the foot of the driver, RPM, MPH, Oil Temp, accurate digital Thermometer, Actual high and low side Gas Pressures for 0.95 lbs R134A refrigerant


regardless

this tread is about reversing the gases

You just don't get, do you.

The factory system is perfectly adequate when "underway", engine RPM consistently elevated. It's when the engine fan and the front blower provide insufficient cooling for the A/C demand requirement.

Bold type by WWEST

Again, "reversing the gases" is totally inappropriate and misleading.

(Oh, by chance are you hooking up the front condenser backwards?)

Changing the serial order of the flow through the 2 condensers is what you are proposing.

Which, by the way, doesn't increase the condensing capability even one IOTA.

Unless that extra 40 feet of hose is acting as an aid to condensing.

This was pretty much my thinking, too.

I know there are more accurate ways to measure actual air temperature (like that nifty thermometer that Griff has shown), but for my purposes of charging/tuning a/c systems, and for my own general curiosity, the IR gun is fine; after all, the true measure of performance for me is that the system can freeze me out even in sunny, upper 90s, high humidity, stop-&-go and highway driving, and quick cool down after extended vehicle heat soak.

A/C Reverse The Gases in Early Model 911's W O R K S VERY WELL!

Figure out how to do it from the hints and pictures I have posted here

Don't expect 30 degree vent temps like I get using this method @92-95 Ambient
You do not have my PFC's!!!

test it

you should get much lower a/c temperatures than you get now regardless of your condensers technology, and its well worth the effort

I am sorry but I have never tested this invention on OEM tube and fin i.e. Behr or other stock condensers technology most of you probably have; so I have no idea exactly what temps you will get?

But I do know for sure you will get lower a/c temps by simply reversing the gases and your oil temp will also be far lower in the summer or when ambient IS HOT and your using your A/C!!!-(For this reason alone you will want to do/try/test this)

This Truly Works!!! This IS NOT BS!

I am trying to give you something FREE

And yet you cannot articulate even one. In a TECH forum, you actually have to be TECHNICAL.

And you wonder why nobody takes you seriously.

I wonder.... Did you FOOL yourself?

Did you first test the black swan in OEM configuration for a control reference?

Then tested again with your PFC condenser and the front condenser first in the flow?

Hey, Eric.

In Ohio, to make time with a babe, slam dunk, just say something nice about her tooth.

you have dogged me for 4 years are you really this stupid or senile?

I have always been into engineering ONLY new technology PFC's for early model 911s


Why would I bother with old a/c technology OEM condensers to do testing?

[Ronnie's.930]

Bob, did you get Eric's permission to post that picture of his solo-toofed wife? If not, that's mighty uncool, bro!!!
