It's getting HOT and summer far from over. I'm looking for alternatives to a conventional HVAC system. I like the ideal of electronically run ac and heating system that will not rob power from the engine. I was wanting to know if anyone swapped HVAC system from an electric vehicle?

Thanks in advance. |

Check out Classic Retrofit. He has a pretty impressive setup for the 911. There was mention of working on a 914 setup, but nothing on the website. Either way, I have seen some pretty good reviews from people on the Pelican Forums.

That and a standard condensor in the front trunk and under dash evaporator and you have a complete system. How big is your alternator? The compressor draws 40 amps + condensor fans and evaporator fans, stereo, lights, etc. |

I've seen mini swamp coolers that are quite small, require about 20oz of water every hour or so and would fit in a corner on the floor, drawing very small amperage from your accessory outlet.

All in, the system is ~$5,500 for a 911. I know they are working on a 914 version but it’s not out yet. They sell as many 911 systems as they can make so the 914 probably isn’t a priority but like Steve said, they sell parts individually. |

I’ve used a B-Kool on several 914 Treks during the summer and it works quite well. I drove from Mammoth Lakes to Phoenix in June during record desert temps of 120F coming back from WCR a few years ago and it was not that bad. Tinted windows would have really helped. If I remember correctly I used 125lbs of ice. 20 lbs of ice lasts about an hour and I carried a second ice chest so I only had to buy ice every 2 hours. My only mod was to install a trailer-hitch style connector because a cigarette lighter plug can’t handle a 10 amp load for hours on end.

(IMG:style_emoticons/default/idea.gif) Thanks in advance. The compressors from electric vehicles require 200 to 400 volts DC. A new 12 volt compressor can be found about $550, the down side of the low voltage is the current draw is 60 to 70 amps. You will need a high output alternator, something that can produce at least 75 amps at idle. That is typically a 150-200 amp alternator. I would install a higher amp hour battery as well at some point. |

Is that the Brit guy doing the electric A/C? He is having his 914 fitted with an EV system on the TV show "Vintage Voltage", fit almost wholly within the Appearance Group center console, looked like a nice setup.
Big spendy dollars though. |

the stock alternator is what....? 50 amps or is it 35
either way, my concerns with electrical systems is that none of these cars were intended to produce or carry high amp loads overwhelming the electrical wiring is a concern with upgrades I think if you need modern AC and heat then the easiest solution is to buy a modern car |

I like the ideal of electronically run ac and heating system that will not rob power from the engine. That's not how physics works though. A large electrical current draw will still rob power from your engine. (IMG:style_emoticons/default/shades.gif) |

Or move to the PNW. High of 75’ today. Might make 80 this week!

I just noticed an article on their site showing their electric ac in a 912. So it looks like they (or someone) have an alternator that will work with a 4 cylinder engine. They don't currently offer a fresh air blower to fit a 914 but maybe we'll see it soon.

Or move to the PNW. High of 75’ today. Might make 80 this week! We might get down to 75F for a few minutes in late September. Right now you have be out at 4:30 am to enjoy brief few minutes when it dips below 100. I drove from Prescott yesterday and through some strecthes reached 126 through the Sonoran desert. The 6.2 in the Superduty and modern AC was just able to disspate that heat towing our Covid townhome behind us back to Cali. I.d go with the evaporative cooling solution. |

Bit of a branch question from the main Electric topic; has anyone tried an alternate condensor to cutting the frunk floor?? Just wondered if there's scope to mount one in the engine lid (possibly a narrow condensor in a double 914-6 lid) and still isolate it from the hot engine compt air below - or is that just unrealistic??
I'd love to fit one but don't want to cut up the frunk? |

The guys in the UK said they could put one in right rear wheel well.
I have not seen it done yet. Since I have a six with a front cooler, I just installed two PMS louvered sections in the front trunk. Easy to do. The oil cooler hot air exits before the condensor. PMS did the same thing in there 916 retro build. |

He said that should result in no cutting needed. He's a 914 enthusiast but he knows the market is in the 911's. |

just incase you are wondering what I'm running it's a WRX EJ20. At the moment I have the car set up without AC and a heater but planning to incorporate that in the future. My alternator output is about 75 amps. I want to make it clean and simple under dash. thinking electrical for both ac & heating but not ruling out conventional HVAC system.
I like all the ideals thus far. (IMG:style_emoticons/default/aktion035.gif) I found this on youtube university. I know it's not a Porsche but it has some useful information about electrical ac system. Check out where he put the ac condenser, WILD! I didn't think it would cool the freon efficiently in that location. https://youtu.be/mRo05wph2F0 Also, Call me crazy for thinking of heating system as well in the middle of summer. What options are there to keeping the cabin toasty in winter other than heat exchangers? Any electrical options out there? |

Mark,
Is Johnny from the classic retrofit outfit in Horsham?? I need to have another look and try to work out what condensor they're using! The guys in the UK said they could put one in right rear wheel well. I have not seen it done yet. Since I have a six with a front cooler, I just installed two PMS louvered sections in the front trunk. Easy to do. The oil cooler hot air exits before the condensor.
