It seems that what he actually meant to say was that he "invented" the idea of rerouting the high side refrigerant flow path, the front lid condenser first, then to the rear lid condenser and then to the dryer.

His claim was that this technique improved the refrigerant condensing efficiency substantially, well enough to justify the expense. No qualifying of the exact or approximate level of improvement was ever offered, as was the case of an engineering explanation for the gain, insofar as I am aware.

My own measurement of CSA airflow for the 2 condensers seems to put the lie to his "invention". Even at idle the rear lid condenser gets a higher level of cooling airflow, and the equation gets worse with rising engine RPM.

"Throw" in his "improved" PFC front lip condenser and matters get ever worse, as the new condenser actually BLOCKS(***) forward motion cooling airflow whereas the factory condenser takes advantage of this effect.

*** As is the case with ALL aftermarket front lip condensers... PUZZLING, EXTREMELY so.

Ah, ok, thanks for the summary, thats pretty much what I had gleaned.

I think one of his main features is a high performance front condenser with special shrouding and hi flow fan. He showed pictures of this somewhere. That could potentially indeed successfully dump a lot of heat away from the engine. Again, there are glimpses of ideas that may work, but no before and afters, or other comparisons.
I wish him well, but we may as well wait for Gilles to give us actual data or at least impressions.
Good luck,
Dave

Gilles wont release anything on his own!

The charlatan modus operandi continues, then - nice!

YES THIS REMOVES MASSIVE HEAT from the front PFC

Gills does NOT have this initially BUT IF HE WANTS ICECOLD911 @ 100 F plus ambient he will discover his OEM front blower ain't going to cut it!

AND NEEDS SOMETHING LIKE THIS!!!!!!!!!

YOUR THINKING IS WRONG ABOUT ENGINE HEAT AND WHAT IS GOING ON IN MY DESIGN!

Shouting doesn't make your point more clear, nor does it clarify his confusion over your design goals.

DaveMcKenz 05-11-2016 07:17 AM

Thanks, Reid.
Please clarify. My image is that you have a big honking front condenser and fan assembly that dumps a lot of heat, first. Then you have a very efficient rear PF condenser. You use an orifice valve and accumulator too. Besides control and air distribution, what am I missing?

Reversing The Gases

KelogGes 05-11-2016 07:41 AM

kenikh GET YOUR CRAP POST OUT OF HERE

OR I will bring back the moderators

KelogGes 05-11-2016 07:48 AM

maybe its time to do this anyway!!!!!!!!!!!!

Hi Reid,
I did include the reversed gas flow, by saying you send to front condenser first, then rear condenser. That's the only reversal isn't it?
Thanks,
Dave

yes


Think HARDER

There is basically no noticeable engine oil temp increase when the a/c is turned or off
With my design

The OEM A/C Design greatly increases oil temp when the a/c is on as ambient temperatures increase

That is exactly correct, including all of the "secrets" that we are not supposed to know about yet do...
So, when Reid says "your thinking is wrong" he really means "you are 100% correct and understand this perfectly", just as when he says "invented" he means "didn't invent at all".

See? He makes perfect sense, once you put his posts through the Spiderman Decoder Ring.

KelogGes 05-11-2016 08:39 AM

its unfortunate I have decided to not post the install here, you had your chance
oh well!
