Hi, I am in the process to install an original 914 VPC system in my 914-6.
Like all my projects, I work on a budget. First I bought all the parts about 5 years ago, then I refurbished all parts, (professional cleaning, expansion valve) installed the condenser in the front trunk as designed, temporary installed the evaporator console under the dash, and start the preparation process for the compressor installation. I want the installation to be as close as possible to a factory one. For me, is not an option a compressor under the engine, a serpentine belt or similar. I prefer to work extra time, and reach a perfect end product. I used a double pulley from a 74 911, in order to install the pulley and have space for the dual belts, I have to shave a bit the original engine support and the engine cover (see photo). I fit a 2.2 or 2.4 bracket. So far no problems, the end result looks very nice Now I need to choose the compressor. The York is out of question, due to size and efficiency. My options are a Sanden, a Denso or a Panasonic. Any one fitted with a one groove pulley Not being familiar with the air conditioner compressors, and the way you need to calculate cooling capacity vs cabin volume, I would like to ask help form all of you. 1. Which compressor will suit my needs the best? 2. Which compressor is the smallest one? 3. The best compromise? I will keep all of you posted of the progress on the installation and the need or not of a firewall modification. Thanks Francisco Attached thumbnail(s) Attached image(s) |

The other accessory drive on my engine is for power steering. The pump mounts where the smog pump used to, like Clay Perrine's compressor mount, only the pump is much lighter than an AC compressor and not hung out as far as Clay had his.
I don't have my whole system running just yet, but no, I'm not going to use any of the usual 914 AC components. I'm using a condenser coil from a Honda Civic and making a custom evaporator using a 911 coil that replaces the stock air box. I'll post the result when (and if) I get it all finished. Not sure about GeorgeRud's point, since my engine has the stock CIS FI. There is room to hang the compressor out farther to the side than I have it, and If you go far enough with that you can lower it enough that my solution sort of turns into Clay's. |
