About to start converting my 350z track car to tesla power this will be used as a test bed along side Kevin's and Damian's projects. I will be using the large rear tesla drive unit which i brought from a 2015 tesla model s 75d with only 1600 miles on the clock. It will be fitted out with Damian's open source control board. The plan s to use as many tesla components as possible.

Everything will be set up on a bench first then i will strip all the redundant 350z parts and build a custom tubular rear subframe and battery box from the front.

Re: Tesla Powered Nissan 350Z

Pretty please put the front motor in as well!
Can you expand on how you will use the charger, ac and other Tesla bits? I got some bits from a motor from a tesla for my project but have left behind the charger, ac because i dont know know if they have been hacked to be used in DIY projects. I'd also love to use the screens!

Re: Tesla Powered Nissan 350Z

I have thought about using a front motor as well but am gong to get this set up running first then possibly in a future project. The charger has been hacked Damian is currently working on a replacement board. Check it out http://www.diyelectriccar.com/forums/showthread.php?t=187345

Re: Tesla Powered Nissan 350Z

Been doing some battery box design and development. Will be used in the 350z and can offer as a service in the future along side other conversion work.

The frame will have an outer metal box and coolant system within the metal frame work.

It is built in 50x25x1.5mm box which is light weight and strong did look at angle but would of require more of it to make structurally sound and the weight would of ended up the same plus I like the built in coolant system could also be built in aluminium or stainless.

Photos below of build so fare and a basic design. Also test fitted in Kevin Sharpe vw split screen.



There will be a return coolant system fitted to the top frame.

Tesla Powered Nissan 350Z

Are those galvanized iron tees, and how are they connected and sealed to the frame tubes? It's an interesting approach; I'm just curious about the details.


Hi Brian,

They are only in galvanised for prototype I have ordered stainless steel pipe and tees to replace them with as galvanised does not cope well with coolant .

Within the box section there is a piece of pipe with one tee and one 90o elbow with threads on the end that pop up through two wholes in the frame the tees are then screwed to them in which I will use ptfe or some sort of temp proof thread lock. The tee and 90o within the box section will be stainless tig welded on so they are completely sealed and can never leak.

I will making sure they meet reg100 r1

Thanks for your comment.

Thanks

Chris

That's reassuring! :)

I was thinking that you were going to use the frame sections as pipes, but it sounds like you will just be using the frame sections to enclose and conceal the piping... which makes sense but is very different in construction. If that's the plan, then where fittings come through the frame section wall I would want some form of bulkhead connector, rather than just having the frame section wall trapped between the parts of a common pipe thread connection. Does that make sense?

I read that as the stainless end pieces of piping will be welded to the frame solidly so the connectors will seal against the welded piece and the pieces will return strength to the frame where the hole was for it to exit...

Sounds good to me.

Hmmm... I read it as the piping and connectors internal to the frame would be welded to each other (to keep them from unthreading or leaking, because they are inaccessible), not to the frame. The welded assembly of piping and fittings (a tee and an elbow) would be inserted into the frame tube from one end, then the visible tees would be threaded onto the protruding fitting ends; the plumbing assembly would be removable for inspection, repair, or modification.

Since we're into fabrication methods... welding pipe-threaded fittings should work (particularly since this appears to be a low-pressure application), but that's not how they are intended to be used. If the internal connections are going to be welded anyway, there's no need for the threads at those connections at all.

Correct I did consider building frame out of stainless and using the box as the pipe but is a pain when regulating flow plus need to put fittings into the bottom of the frame to hold the outer box.

Your right there is no need for the internal connections to have threads but I am struggling to find weld on angles and tees with an outlet thread.

Thanks

Hi Chris
For our clarity and sanity, please confirm which POIs you are welding and how the pipes are retained in the frame.
Thanks

Cheers

So there will be a stainless steel pipe in the frame with two threaded uprights that poke though in which the tees then screw onto. By screwing the tees on it will hold the pipe security and there will also be a finishing plate on the other end where it stick out of the frame to secure it.

Hope that makes sense I will upload some close up photos over the next few days.

Thanks

Chris
