Modern Love: a 1983 SC

It's a bit of a long, circuitous story, but I recently got around to fitting one of Jonny Hart's Classic Retrofit air conditioning kits.  The kit itself is pretty convincing and comprehensive, coming with everything but the air ducting (Webasto-style 40mm and 60mm hose) and the obligatory scraped knuckles, which you have to supply yourself.  There are three main components: the evaporator/blower, the compressor and the condenser.

The evaporator/blower unit fits in place of the original blower:

It must be said that fitting the air ducting on the passenger side is remarkably like fitting a quart into a pint pot.

Then the evaporator/blower goes in:

...but it should be noted that there are a few tidying-up jobs to be done first, e.g. I relocated the wiper intermittent/park relay, 'cos once that evaporator is in, you'll never want to remove it again.

Then the condenser goes into the front end of the passenger side wing:

You have to turn that photo 90deg anti-clockwise to view it!

And then there is a compressor assembly to build up and install in the boot.  In the case of a RHD car, it goes in the front end of the boot, near to the battery (whereas in LHD cars it goes into the smuggler's box).  I must take a photo of that (ahem).

Finally, there's plenty of wiring and refrigerant hoses, connections and fill valves to keep you occupied for a few hours.

I haven't had a chance to get the system filled with gas yet, so can't confirm how effective it is, but will do so in the coming days/weeks.

Almost forgot: to fit the condenser, you need to relocate the windscreen washer bottle.  I fitted a standard aftermarket one, using a filler neck from a Nissan (she'll never notice!) in the front offside corner of the boot:

I got the a/c system gassed today, and can report that it is working well.

I had previously followed the set-up instructions, downloading Jonny's most recent software to the dongle and then plugging the laptop into the compressor ECU to check the various items were working - all checked OK.  I like it that you can display all the parameters on the laptop and see them in real time, too.  I felt all scientific for a few moments.

The only thing I wasn't able to do was get the system pressure tested (Jonny recommends 10 bar) as neither of my favourite local garages could do that - so it was just fingers crossed and gas it up.  But as I say, it seems to be working well, just as you'd hope.

Good to hear it's all working well, mine is a complete success too and could not be happier. Not only do you get a comfortable car which really transforms the experience of owning/driving one of these classics but also the great design allows you to free up the engine bay and readdresses weight distribution. It's fast becoming a must do mod and will add at least what it cost to do to the value of your car, if that matters.

love your build, may I ask where did you get the new ref counter dial? I would fancy a red one😄

If you've read this thread previously, you'll know that the exhaust back box is a modified Dansk item.  I got Infinity Exhausts to take it apart and put some silencing in, as the Dansk design doesn't really work with the 2-in 2-out layout.  However, Infinity specialise in straight-through pipes, and my exhaust was always just a little bit on the loud side.  Not so much for the occupants (it was a rather nice raspy sound, actually, not drony at all), but definitely for people following and for the neighbours.  So this winter, a little project was to make it a bit quieter.  I took the back box to The Exhaust Company in Thatcham and asked them to see what they could do.  Here's a picture of 'before' (the Infinity Exhausts design), followed by 'after' (the TEC design):

As you can see, the TEC design is more of a chambered layout.  And the result is rather pleasing: you can still definitely hear it, but it's much quieter on start-up and nowhere near as noisy for following traffic.

nice work gimme, how much do they charge for something like that? I still want an rsr style twin out for mine but a little worried it will be deafening loud with my race headers. My current 2 out (1 to each rear corner) was made by TT and he packed it heavily for me so i could always pass noise tests for trackdays. I think as soon as i put the Dansk RSR box on it will always be well over their noise test limits but if i could get it packed better 'might' still pass muster.

thanks Gimme, yes same, wouldnt be messing with the outlets its just the internals that would need more baffling/packing. Would help if companies like Dansk published the likely dB for their exhausts but probably too many variables. Its only really to satisfy the noise nazis at tracks these days courtesy of the local councils, personally i dont mind if my car sounds like a full race bred RS/RSR :)
