Electric Supercar

Hello all,

I thought I would start a build thread. I have ordered a K1-attack kit car. I have started the assembly. My plan is to have a Tesla drive train. I am sourcing from EV-West. Hopefully that was a good company to partner with. I am waiting on batteries until the build is further along. I will definitely reach out to the forum for advice along the way. I am also documenting in YouTube. Feel free to follow along.

Brian, Thank you for your comments. They have been very helpful. I have been trying to research about the battery boxes, best construction methods, heating cooling considerations. It seems that many of these threads start off good and take some big tangents.

I haven't bought any batteries yet, but yes those were the ones that I was considering.

I was thinking of making a fiberglass box where I can secure the batteries well with some steel tubing supports. I was thinking of starting with the air cooled method.

Do you have any good threads or articles to point me to.
Re-Cooling

Depends on where you are - I am overloading my Volt cells and cooling is not a requirement here (Southland)

I like the liquid cooling systems - not so much for actual cooling as for temperature balancing - they do keep all of the cells at the same temperature
Tesla motor is in!!!
Congratulations on a substantial milestone. :)

Photos?
Ha, Ha, I should have been more clear. I mean I now have the tesla motor. It is not yet mounted to the frame. I will post some photos.

LOL oh, well, even that's progress.

Here is a picture
Have you had a chance to confirm that the dimensions match the model you are using?
That's the drive unit and subframe, but you did get the suspension as well, right? My understanding is that the plan is to use the Tesla suspension.
Suspension, brakes, rotors, spindles are still coming (not here yet). Still confirming dimensions. I will see if I can position it roughly in place. I have a neighbor (metal fabricator) coming over this weekend to help me with some mounting options.
It is a little strange to see the Honda struts dangling back there, since the Telsa struts are different (in the lower mount, especially, as shown at the yellow arrow in the photo by Edmunds), and will need to mount in a different location. I assume that Tesla struts are among the various suspension components which are on the way, or that a compatible coil-over shock will be used instead.
The other struts were thrown on to help identify the axle position. Once the suspension control arms and spindles come and are mounted, I will figure out if the Tesla struts or an alternate struts will be used. I am leaning towards an alternate solution thinking that the tesla struts are meant to support a 5,000 lb car and are air struts. Still evaluating, suggestions are welcome.

Thanks - that makes sense, given that the Honda struts are vertical and approximately on the axle line. :)

The air springs could be handy because of the weight mis-match: you could just run lower air pressure. Of course coil-over shocks would provide an nearly infinite choice of springs, with some choice in length.

When the still image shows a battery box, I'll assume that the latest video covers battery box design and fabrication. Will that work?
Still don't have any batteries yet to necessitate battery boxes. If you have any suggestions or threads to research, please feel free to give me some insights.
That is awesome what you to do... How much does it cost to charge an electric car with solar power? I found interesting review hom much it cost https://websolarguide.com/how-much-do-solar-cars-cost/
