How's it going? I'm interested in a model A (aircooled) and soon.

Stalled yes, but not out.

Been a series of unfortunate events. Electrical went to gremlin paradise during the time the car's been stored, missed my WCC deadline and my window. Then June was hot as hell and I couldn't stay outside for any significant time. My WD Black HDD has failed twice since May, lost the design files and the suppliers list. Luckily I still sketch/draft some things on paper but it's been like starting from scratch. Add to it I'm a pretty busy fellow without "challenges".

I'm interested in Model A, Chris.

WD HDDs should be renamed WMD ... I use 'Time Machine' and a portable back-up drive (IMG:style_emoticons/default/shades.gif)

Would love to learn more about what you are doing? I'm trying to figure out how to get a better A/C system without cutting holes in the front trunk. Just my preference....

http://www.914world.com/bbs2/index.php?sho...=261281&hl=


However, the big part is getting a combination heater/ac(evap) blower box. I see in the beginning of this thread, it appears you got something from Hotrod air (or similar)? Obviously, that thing has a controller. Looks like you were trying to customize it so that the knobs looked a little more correct in the 914.

Does the blower unit fit under the cowl (and slot for fresh air)? Are you able to get water drained away from it if it is hooked there?

boxsterfan- I'm actually making a box that fits. Uses the 914 air directors/dash levers. All the "Hotrod" boxes are built for big Hotrod dashes. Plus I can build them with latest design cores, which are smaller, and keep the price in the same range.

The knob stuff is just the on/off switch for the compressor. I'm trying to find something that looks factory, like an insert in a repurposed fog light switch.

Drainage, for both rain washing and condensation, are accounted for.

Happy to hear that you haven't waived the little white flag! Entertain the thought of just selling your custom airbox with evap coil and blower (as a package option). For my conversion, I was planning on doing my own wiring, as the ECM controls the request for AC. I'm not sure how comprehensive your final kit will be, but for my LS conversion, I already have a compressor and condenser. I'm sure other water pumper conversions have provisions of their own as well.

Should I keep my old condenser handy? ('70's era dealer/vendor installed option) then source a new compressor & dryer for 134A?

timothy_nd28- I'm only selling the unit and the few things needed to essentially replace an under dash unit. Too many engines with too many options to do a full kit, with too few buyers.

I am, as part of looking at the big picture, looking into solutions to the other pieces involved, like the switch and condenser, so 40 buyers don't need to blow time looking for answers to common questions. I will likely make an AC appropriate insert for the fog light switch as it's the best match for the interior, unless I find one.

euro911- At least until someone provides a new tech replacement. May or may not be me. Someone here made a kit for the Sanden for the T4.

I totally agree with you. Back to my original question on page one, what style metering device are you planning on using with the evaporator coil? If you are using a fixed orifice, then there will be no issue. However, if you are using a thermostatic TXV/Hblock dealy, will it be compatible with R-12 or are they rated for R-134 only?
I have a jug of R-12 buried in my back yard, and I wanted to put it to full use.

Essentially stalled pending a car that wants to be driven (IMG:style_emoticons/default/headbang.gif)
Need to make sure all the pieces work well together before writing $1000 checks.

For your other question, fixed orifice common in the hotrod market. Available in r12 and r134 sizes, so you're covered.

Do you happen to have any prototype boxes that you are willing to part with?

I'd be all over one for A/C today if available.
