A/C Reverse The Gases in Early Model 911's

I think that the factory routing was an attempt to keep high-delta-T's; this generally results in greater heat transfer.

The high temperature gas is cooled by the engine compartment condenser with medium air temperatures. Then the medium temperature gas is cooled by the front condenser with low temperature air. Theoretically this would result in lower final liquid gas temperature. However, when theory meets reality, then things can change. If the front condenser now does almost all of the cooling, then the rear condenser may even be a liability. I would carefully check inlet and outlet temperatures on the rear condenser to ensure it is still contributing to the cooling; it may not be, and in that case should be removed.

Are you supposing lower temperature airflow source for the front vs the rear...?

Or are taking the radiant heating effect on the rear condenser via the engine/exhaust into account?

It's hard to imagine that removing the rear lid condenser, ~2/3rds of the total condensing capacity, would net anything other than a negative result.

And to think you have the nerve to call other people "slow & stupid"!

SHUT UP you have no idea of my prior conversations with Tippy

I gave tippy good advice!

Given your public record that's hard for many of us to believe.

I wish someone was still making those underbody condensers, they work very well.

They may work well when "underway", but not very well at all for the periods our Porsche A/C most needs improvement.

Subject to road debris, radiant heat from a HOT roadbed.

Not in any way worthwhile.

Hi RSTarga

Are you talking about a belly-pan condenser?

Or something different?

As I custom make make condensers sometimes

I was interested in the belly-pan condenser and information about it
And had several conversations with 30 plus year expert Porsche shop owners and mechanics at length and informed none of them ever worked very well !

because there was no room for a/any blower, and they also picked up a lot of road heat radiation

Not to mention there was no room for a rock guard

Where does your information to say they work very well come from?

west why do you keep following me around you know what I think of you

Go take your meds there are enough crazy people drunk or on drugs in here already!

go disrupt a thead someplace else

I don't care f***-all about your invention. Calm your ass right down, you spoiled brat.

You like to s*** in people's nests. You will pay for that.

Keep it up.

Mark my words.

Regardless of what you might think of me for whatever reason the information I have posted here is true really important information and if reversing the gases is used on an early model 911 it is a game changer for making the a/c system make cold far better than the standard way regardless of the heat exchanger used and for over 35 years everyone has simply had the wrong mind set!

Try it and you will discover what I say is true! What have you got to loose?

You :"roflmaO"

Makes no sense. Are you trying to say that I'm wrong about my car? That you really DID discover this, despite the fact that there is a standard installation that predates your discovery by about 10 years (when this was installed on my car)? Do you think that sending it to that tiny front condenser (while heating up the passenger compartment with hot lines back and forth, 20 feet of them) is better than sending it to the 2x4 foot massive passive condenser? I gotta say, despite your claims, this underbelly setup is pretty nice...

Um...several weekends and hundreds of dollars tearing out the old hoses and running brand new hoses back and forth, back and forth, probably 20-25 feet of EXTRA hose since you now make 2 complete circuits around the length of the car instead of just 1.

Yep..almost like an extra condenser in the high side plus extra refrigerant capacity..probably helps deliver more fluid refrigerant to the tiny 911 evaporator. Don't think it is worth the effort myself too. Will it work..sure..but is not "reversal of the gases"

I am not making a judgement on the tech end. Just lighten up.

TEST 1am early Sunday, ‎December ‎02, ‎2012 Reversing the Early Model 911 Gases Proof This Invention Works

[KelogGes]

This 911 I call THE BLACK SWAN GETS 37 F degrees average vent temps at @ 95 F degrees using my custom designed PFC's (without freezing)

The owner is extremely happy to say the least!

It uses only 0.95 lbs R134A refrigerant

This test was accomplished using a couple of pieces of hose fittings and hose clamps

All the existing hose was only disconnected and left in place until the next day so the shop owner could see how well the test worked

He liked MY INVENTION so well it was completed the next day using the new invention!
He has done several 911's since The Black Swan using my invention for his clients

Pictures swallowed by a black hole or just your way of remaining secretive?

There is no d in refrigerant.

Sherwood

he invented re-sequencing the condensers, even though it had been invented decades before

He also invented putting modern heat exchangers in a 911, even though people have been doing that for ever

I am beginning to think he doesn't no what innovation / invention means

He didn't even invent abrasive AC related posting, though he is quite talented at them
