As summertime (2017) was soon approaching, at this point, I decided to try and get the AC system we had installed up and running.  

 

As much (or as little) as I know about cars, and as much experience as I've had with them over the years...AC systems are one of those things I've never been much of an expert at.   

 

I understand the integral components, and the way the system operates to produce the cold air inside...but it's the whole high pressure/low pressure, dual gauge side I never really knew much about.  They've always been kind of a mystery to me and I've never really taken the time, nor had any reason, to try and understand them. 

 

Since the system was brand new, I knew I couldn't just go to Pep Boys and buy a can of Freon and pump it in.  

 

The system needed to be vacuumed to remove the air in the lines and ensure there were no leaks, there also needed to be some oil added...and then of course the whole high/low dual gauge bit to get the right amount of Freon in since there was no OEM manual that was going to tell us the capacity.  

 

I'm pretty OCD when it comes to my car and really the only other person who had touched it beside me was Doug...he's the only one I trust blindly.  Other than him, I simply can't just take my car to any old shop and certainly couldn't leave it there to be worked on without me present.  As a result, I had been putting off getting they system filled and running because it was still the cool season in Miami and it was easy to ignore.  With summer approaching I now had no choice.  Since going to the nearest Goodyear to get the system filled and running was out of the question, I searched for a boutique AC specialist and found a guy that specialized in vintage car AC systems.  

 

He vacuumed the system and my primary concern was soon put to rest as the system held vaccum and had no leaks.  But that was as much good news as I was going to get for the day. 

 

As luck would have it, his fitting for the low pressure side was faulty and he couldn't get it to seat properly...so he couldn't charge the system...

 

He told me he needed to order a new one and told me to check back with him in about a week.

Winter in Miami is very brief and very fleeting.  While it spans only 2-3 months at best, it really consists of sporadic spurts of a few days of cool to "cold" (by Miami standards) weather at a time mixed in with warm to downright hot days the majority of the time.  The only consistent change in weather during the winter, for the most part, is milder, if not bearable, humidity.  

 

By the very next week, the weather was hot and, even worse, rainy...Even if I would drive the car in the rain...which I would never...driving in the rain without AC is among the most unpleasant experiences, made worse by the fact it was hot and rainy.

 

So one week turned into another, and another and next thing you know it's full blown summer with temps in the 90s and humidity in what feels like the 100's.  Attempting to drive the car in that weather without AC, to go and get the AC filled, would result in soaking my clothes, and the interior of the car, in sweat.  So I had to wait for mild weather to make any attempt to try and get it filled...and there wouldn't be any mild weather again for almost 9 months. 

 

Up north I know it's common practice to put cars away for the winter...here people often put cars away for the summer mainly because of the rain, myself included.  

 

I wouldn't drive the car again until December.

Fast forward to December, 2017...cold weather, or what local motorheads like to refer to as "Turbo Weather", had arrived.  

 

Normal people here say "hey it's gonna get cold this week", people in my circle say "hey man, turbo weather this week!" 

 

Now that it was cool out and there was no chance of rain, time to take the car to get the AC running right?   

 

Wrong...why do today what you can put off for tomorrow?  I had been waiting so long to drive the car again that when the cool weather arrived all I wanted to do was drive...I wasn't in the mood to fix at the moment.  Plus I knew I had a good 2-3 months to address the issue so naturally I procrastinated and just enjoyed the car.

Wow what a great read and the attention to detail! A couple quick questions:

1. What size injectors are you running?

2. What tires are you running to hold all that power? 

 

The injectors are some outdated 1200cc's RC injectors.  The tuner told me they are really sloppy and it's noticeable on the low end driveability and startup.  He said that I could probably pick up a few HP at the same boost levels just from getting new, more efficient injectors.

The tires are Nitto NT05R drag radials 275/40/17 (the front tires, at the top of the picture, are Yokohama A008's)

I wonder if the sloppiness is from the size of the injectors or the brand. I'm running a set of RC injectors but they are 750cc.

I believe it has to do with how old they are and the efficiency of the spray pattern...or lack thereof.  

 

It should be a mist and these are more like a garden hose.

Almost caught up to present...

 

While the AC could be put on hold because of the cool weather, one thing that couldn't is the alignment.

 

From waaaay back to the time we did the rear wheel setup modifications, we had put the car back together and basically aligned it by eye...I had never gotten the chance to have it properly aligned.

 

I made any appointment with a local boutique shop that had been recommended to me by more than one person that I trust.

What a difference...it was like driving a different car.

Freshly aligned, and cool weather in season, I decided to head out to a local weekly car gathering that takes place early on Sunday mornings. 

 

This particular Sunday just happened to be Christmas Eve and I felt just like a kid at Christmas 

 

The meet takes place in an area of town called Wynwood that used to be a less than desirable neighborhood and has turned into the new hip area of Miami.  The meet has been nicknamed Cars and Coffee as it meets in front of Panther Coffee.

 

Panther was closed on this day though...I think it had something to do with the fact it was Christmas Eve?

 

In any case, as a result, the turnout was a little smaller than usual...but the lack of traffic in the streets and on the highway made the drive very pleasant.

 

Doug brought one of his toys...

I never realized how small my car is until I saw this photo...even a Corvette looks big in comparison...

Love it! 

 

Funny, 'cuz The one main thing I've wanted to add to my car, body-wise, is a tail.  I'd love to see some more pics. 

 

Do you have a build thread?

Thanks.

 

I wasn't sure on the wing at first, but now I wouldn't be without it.

 

 

 

I have a build thread, its long overdue an update which I'll try and do soon, some major works coming up soon.

So the new year rolled around, and the cold weather was still hanging around so I decided I better address the AC sooner rather than later...

 

Took it to a place called Kiki's Automotive that had gotten strong word of mouth for quality AC work.  

 

IMG_3883.thumb.jpg.e4685a1fcd1fe93eddf0fee0c3308334.jpg

 

The owner and his son couldn't have been any nicer to me.  

 

Sensing how nervous I was about anyone touching my car, they cleared out a space, worked on it personally rather than have one of their mechanics do it, and treated me and my car like serious VIP's.  And most importantly for me, they allowed me to remain in the work area and hover over them while they touched my baby.  

 

They first vacuumed the system and, perhaps most importantly...it held vacuum.  No leaks!  

 

Now that I knew they system was sealed, all they had to do was charge it and I would finally have AC in my car!

 

Or so I thought....

 

With the system fully charged, I started the car to feel the magic of cold air pass through the ventilation system for the first time and...nothing...

 

We looked at the compressor and it wasn't kicking on.  

 

Now this is where I will admit ignorance about AC systems...the owner told me that the two different gauges had to equalize, or something along those lines, and they weren't equalizing...I had no clue what that meant, but according to them there was some sort of blockage in the system.  

 

He believed it was the expansion valve (which I have no clue what that does)...long story short they swapped out a new one annnnnnd....nothing...

 

This whole process took most of the day and it was now closing time for them.  

 

The owner said that he wanted to swap the dryer next as process of elimination to find the blockage, but since it was late, and the weekend...he told me to come back on another day when they could focus on it the whole day...

 

The dream of air conditioning still eluded me...

I drive the car home and am giving it its normal once over of affection...and I noticed dark patches on the front side of the intercooler...weird, I thought...

20180113_155824.thumb.jpg.22db30af65d472cf2a152322867463a5.jpg20180113_155858.thumb.jpg.a57ef8cb0dbcc70369deeef9fe52b825.jpg

 

 

Was the oil cooler behind it leaking?  But even if it was why would it leak forward especially with air pressure going towards the engine bay?  

 

Turns out the intercooler has some small leaks, and in more than one place...ugggggggh!!

 

Had this been an inexpensive Chinese core off ebay, this probably wouldn't have surprised me, but it certainly wasn't what I expected from a "top quality" intercooler like Bell...

 

The thought of all the work that went into that thing...and all the work it would take to get it out and re-do....:icon11:

 

Hopefully at least Bell will be cool about it and warranty it out for me.

I love the car, what paint code is that? Is it a factory color 903 or 115?

Such a great looking Z.

 

Hard luck on the AC, I hope you get it sorted soon without too much more hassle. I'm lucky that I do'n't require AC where I live so I don't have that headache, although sometimes I do wish the weather was warm enough often enough that i did require it.
