Watching motor trend, and saw a 914, and thought okay, I'll watch that, don't like the show all that much. Interested in the concept, engineering can be a bit off as can the logic.
Place battery box in the 914, they decided to load from the top down via the engine bay. Save yourself the trouble and build from the bottom up, and place the pack on a stand and lower the car over it. Come on..... But the usage of the Tesla rear motor should make a nice run at it. It is the details like that that drove me nuts. But in the first few minutes of the show, I started linking pieces together. UK fitter of modern electronics into older cars, specifically AirCon. Its got to by Classic Retrofit guys. Then I say some of the parts being prototyped, and while I am not a huge fan of the center console, and wish they took the time to redo the fresh air blower, it works. Show Vintage Voltage - Season 1 Episode 10 Aircon bits original console and side vents piped in. Production on the car stoped due to COVID-19 Not a huge fan on the changes they have planned to the body, but each their own. I get making it more aero, but come on Ronal Turbo wheels are not any more areo than lets say a Mahle Gas Burner. And in an EV I would go for lightness and low drag over looks any day. So hopefully the car comes together, it looks good, and we end up with another potential aircon solution. Not being a petrol car, means the electric aircon can be placed anywhere, so crafty placement might still be on us. BTW, could nt find a way to share the video link, only Facebook and Twitter. |

Aside from the conversation about available distance w/o a charge, the one thing that has struck me for every EV conversion I have seen is that the ride height never seems right. They all look like they have lost a bunch of weight and no one replaced the shocks or springs. They all seem to ride way to high.

They usually weigh hundreds of pounds more with all the lead batteries. |

I agree but I've only seen 914's with lead batteries. I have not seen any of the newer builds. Granted, I'm in Delaware and not exactly the tech hot spot of the country.

(IMG:style_emoticons/default/beerchug.gif) Same here in So Cal. I have seen several really nice professionally done cars, but always have heavy lead acid batteries, no trunks and only around 60 miles a charge capability. Looking forward to more details on this build. |

Looking forward to more details on this build. Wow, are you sure? My 914 was originally converted years ago but still had Lithium batteries, albeit old school ones. Anyhow, now we have 42kWh of modern LG Chem Lithium Ion batteries, which should give 150 - 180 miles of range depending on weight of right foot and HVAC usage. We are also integrating some other new tech, notably power brakes (Tesla) and power steering. |

If you offered a kit minus the batteries due to shipment weight, with battery trays, detailed instructions like your AC offerings with at least a partial trunk, I think there would be quite a few interested parties. I agree lithium has been around for awhile. I don’t know why the ones I have seen were all lead acid batteries. Probably due to cost since most of these were high school or college experiments. |

I agree lithium has been around for awhile. I don’t know why the ones I have seen were all lead acid batteries. Probably due to cost since most of these were high school or college experiments. Cost is totally the reason why. For the past 15 years homebuilt EVs have been the land of tinkerers and experimenters and students. These types of people usually don't have big budgets, and the proof of concept is that the car moves on its own power even if the range is short. Spending bigger money on bigger and lighter batteries may not make sense for the guy that just wants a torquey weekend warrior car the probably won't be going more then 50 miles on a post school/work/weekend blast around the neighborhood. The rise of EVs as "common" daily drivers and the availability of better parts and batteries is going to lead to better EV conversions. I will fully admit that when I looked at EV conversion for my 914 my threshold was "could I do it cheaper then rebuilding my TIV." At the time my answer was no - but that was before I knew I'd be building that engine three times. lol. (IMG:style_emoticons/default/screwy.gif) If I had built it as an EV I would have lusted over old tech (new at the time) lithium batteries but would have ended up with lead acid and shorter ranges. I love seeing builds like this one, and I hope we get to see how it turns out. Don't tell anyone, but I still think about EV for the 2002 I'm building. Not that I've been able to go and work on it for the past year. Thanks COVID. (IMG:style_emoticons/default/barf.gif) Zach |
