Noooo... that is a competitor's copy or our first revision model built 10 years ago.
Our Serpentine Rev 4 blows them all away.

Did you know that "plate and fin" evaporators, alike the one you are playing with,
introduced in the Boxster and 996 around 1998 are now failing! As well as
all other cars using the same plate and fin designs. Once you figure out why
feel free to chat.

Strange, I am closely familier with at least 5 early series LS400's and none of them have had any evaporator problems other than the seemingly inescapable mould & mildew odors. Oh, I forgot, there is also the propensity to spontaneously and suddenly fog over the interior windshield surface.

I ended up cruising my local hardware store and found a simple plug for irrigation pipes for less than $1. Couple wraps of tape to get the diameter just right. Done.


Most cars have the resistor pack for the fan hanging in the passenger side opening. I think you would want to maintain some airflow for cooling. Don't know that I'd close off that intake. -J

I wonder if there is any way (instead of capping off the bowtie) to route the bowtie outlet to the side vents? These side vents are really weak. I would be willing to improve the side vent performance with a/c at the expense of hacking or even removing the fresh air system.

Yep, Josh, I did the same but with thin sheetmetal. maybe for hose clearances.

Finished , Ive been running it with a tell-tale temp indicator sticker on the cond you can see in the pic, but it has not even reached 190F (sticker range is 190-280F)

My NEW TYPE 911 EVAPORATOR using newer Parallel Flow Evaporator Technology that has slightly smaller dimensions then is currently available for early model 911’s but even FAR more efficient, I redesigned and successfully tested last year and have been sitting on; It will have installers choice, either FOR (TX) “Thermal Expansion Valve”, or even THE more efficient (VOV) “Variable Orifice Valve & an additional (needed for orifice valves) receiver tank installed before the compressor return inlet” ???

This year I have another state of the art new Parallel Flow Plate & Fin Evaporator Technology redesigned prototype for 911s that is wider and perfectly fits the full width of the early model 911 black plastic evaporator case; that is also shorter in length then the OEM 911 evaporator. But I am not releasing pictures of it at this time.

My mind is always thinking of invention and engineering new things to play with; NOTE: this same technology heat exchanger for this 911 evaporator prototype in the picture I posted; I have also been thinking about turning it into another product for state of the art high tech 911 Oil Cooler heat exchangers after looking at the aftermarket DIY Oil Cooler markets.

LOL. What happened to your state of the art new Parallel Flow condensers front and rear that you ranted about but never produced and wasted everyones time with? LOL

This is a Porsche 911 tech forum you jackwagon. No one cares about your experience with Lexus LS400 automobiles.

Before I make a comment about the above post I want to say this

kuehl I respect you very much! You’re a wealth of Porsche a/c knowledge, experience and information always very helpful to others taking your time and energy to enlighten those that have limited knowledge and/or seeking to learn, I like to help others too.

You have high quality a/c products for the a/c technology you are into in your mindset and you have a right to be proud of them!

My 2 main differences with you is my mindset is only into the very latest state of the art a/c technology and I personally engineer design and manufacture all of my inventions myself

It is always my intention to have a friendly and respectful relationship with you and in our interaction I think you have treated me the same.

ON one thing we are the same our products are unique we produce our own designed products, we both are not like other competitors that source other manufactures products they did not design or manufacture and present them as their own.

Respectfully I think our mindset differences is healthy for the aftermarket a/c industry and the end users and makes for good competition, there is plenty of room in the a/c aftermarket industry for several providers to supply the needs for end users.

I encourage you to keep your rationale Serpentine is not obsolete, and furthermore your rationale for providing 911 early model “fender heat exchangers” and never change your mindset!

The state of the art technology I am into and the innovative products & inventions I have recently engineered, designed, manufactured and tested has proven to render them all obsolete and no longer needed!

I am very familiar with the Boxster and 996 evaporator failings! I have been amazed in over the 3 or so years watching Stokes Automotive Porsche swap them out like candy, and make a ton of money doing so! I also know exactly why they are failing too! Furthermore I happen to also know what is very simple to do so they never fail again too

BTW the 911 evaporator picture of my last year’s prototype PF technology evaporator I posted, is not the same plate and fin technology you referred to in your discussion, although it may look a little similar to you on the outside to what you refer too, it’s a very different state of the art animal to say the least.

Regardless I have an even new technology PF evaporator I did not post a picture of sitting here right now, I will release info on if I get caught up with other projects and products I am involved with now.

When you cap the bowtie you are forcing that air up and into the main side vents. I have an 86 with large side vents. I get plenty of air. If I had an 85 or older with the tiny vents. I'd get the triple vent set up from Griffith's. I don't think there is any good way to get more side vent air on the older cars without enlarging the opening. I'm sure it could be done at home, though. You'd need a "Y" or "T" to connect to the opening for the bowtie. Then you'd have to run hoses to the side of car and tie into the factory hoses with another "Y". To me that seems a lot of work just to force air out of the tiny pre -86 openings. -J

Which is why your products have a lifetime warranty, right?

Oh, wait...

Never fear, we "get it" just fine. And the beauty of it is that all your writings here don't conceal the fact that your "products" have very little value to the general 911 marketplace, and considering all of your wild attempts to try and sell them generally, it is unlikely they will ever sell in bulk, and is very likely they will be nothing more than a curiousity in the wider community.

And that's because of you, Reid, and the way you approach things.

I will tell you in all honesty, when I first read about what you were going to provide, i was very interested. Then, the more I read what you wrote, the less interested I became. Not because of the product. If, right now, you offered a full kit for half the price of what your competitors charged, I wouldn't be interested. I wouldn't even think about it.

And if anyone ever asks me what I think about your stuff, I will recommend that they buy from someone else, even if they live in So FL.

Good luck with your hobby, Reid. Hope you break even.
