Thanks Stu for the Monaco RedBull RB20 Auction, just got up of the floor from rolling around in stitches of laugher. You've got great comedic timing. Success with your Porsche build. 👍 Ron
If someone gets a laugh out of my vids, I'm happy. Thanks for noticing. Threw in a low bid on Checo's car but think I was about 3 million under reserve.
Gday Stu, just want to give a big thanks for the content you are providing both on your 928 EV project and other car reviews, Porsche in particular. I love the 928, and can’t wait for the next episode on the EV conversion. A big shout out to Matt as well. Cheers.
Can't wait for the next episode, Stu! I always wonder just how far ahead you are vs the videos being released. I know a fair amount goes into editing etc.
Pretty much up to date now. Matt's had a lot on and it's been hard to make time. I'll need to ramp myself up too and not get distracted by the salvage Tesla.
Great video Stu. You've identified heaps of issues and fixes that the rest of us can use. Much appreciated. Other evs use two radiators so l can't see why you couldn't do the same . Electric Classic Cars in Wales does so and their radiators look pretty compact. Especially for low power conversions like the MG. l reckon you should go that way first because it should be relatively easy to test. Leave the space for the front radiator just in case but l don't think you'll need it. l agree that buying a wrecked ev is risky. All you can do is buy cheaply to offset that risk. l notice that there have been some pretty cheap wrecks go through lately which is good for us. l don't think the market or the insurers have worked out crashed evs value yet . l will be interested to see what the battery case looks like under your model S. All the auction places seem to use forklifts and l often wonder how careful they are with evs. Cheers.
I suspect you might be surprised how many "purists" are loving this project rather than hating it. As a fanatical lover of the cars (well the sportscars anyway) from Zuffenhausen I am loving this project. Certain cars have character and soul that is not beyond the engine or its ICE noise. The 928 has original lines that are timeless and do not look out of date today, it was at its best a continent crusher that could effortlessly travel long distances and then be interesting when you arrive somewhere and there were some twisty roads. Fundamentally as an electric car it will remain true to this role and it will be effortless and likely significantly more reliable. To my mind instead of a classic 928 ending up at the wreckers you are giving it a second life and rather than driving one of the many bland looking modern EVs you will be driving a stylish and beautiful car. I do not see a downside, other than perhaps your questionable taste in colours 😆🤣😆🤣😆
Stu, Putting the radiator in the rear is a great idea, better weight balance too. Lotus done this too in their electric Evija, you can see the cooling radiator when the rear spoiler is raised here. th-cam.com/video/9Fu2s1U14tw/w-d-xo.html If you're putting a sheet of aluminum (or the like) under the rear to protects the motor (flat diffuser), maybe put a few NACA ducts in the sheet to funnel air to cool your radiator and motor.
Re rear mounted radiators. There's a big empty space where the autobox bell housing ( torque converter) used to sit and a trans tunnel to funnel air through. Might be adequate enough size and keep hoses short.
Hey Stu, a lil bit of work. But how about welding up and removing the existing fuel flap and have the charger behind the rear number plate and have it flip up to charge ? Just a thought 🤔 .
Yes, that would be sensible. But there's no room above the fuel filler recess for the wiring behind the plug - which is a sealed unit I can't easily disassemble. I am still toying with the idea of fitting the charge port tucked away somewhere on the back of the car, near the number plate. Or behind it! Like an early Chrysler Valiant which had the fuel filler behind a hinged number plate. Still got lots of options but thanks for the suggestion.
Very much enjoying this project, thanks for showing so much detail. I am curious if you've talked to a certifying engineer about the instrument cluster transplant plan? I would worry they won't want to see any errors showing on the dash (also for roadworthy). Is there a plan for appeasing the instrument cluster?
Good points. Yes have been talking to engineer about registration requirements. I have added back discrete warning lights for the usual things that still come from the Porsche loom - park brake, brake fluid, indicators, park lights, lights, high beam, stop light fail, mainly. But everything the MG also provides should show on the MG cluster. I expect there will be plenty of irrelevant or messages pertaining to no-longer-fitted components to be dismissed - don't have an answer for that yet. Just have to wait and see.
Might be too tight there as well, but possibly behind the seats at the expense of luggage space. Or possibly in the front "engine" compartment by the HV battery. I'm pretty sure we can figure out the battery cooling issue but A/C is pretty important in a 928 in Australia with that glasshouse design. There are lightweight aftermarket options, and certainly the transmission void is a smart idea. I don't mind too much if we have to forgo certain functions like demister. We'll get there.
The Tesla SDU is larger, but it's a much better form factor, with the motor/invertor behind the diff. So it would fit the Porsche better. (I'm guessing we will learn a lot from the first 928 EV8 before we start the second one). Unlike the Model 3/Y motor, and unlike the MG's motor which we had to roll over - they both have the motor barrel forward of the diff.
The trans tunnel and firewall are pretty integral to the central cage and I suspect they contribute quite a lot to the body rigidity. We'll find a way to fit in the various A/C components but it'll be a slow process. I now want to get the car driving first without A/C and then we can find a place to fit those components. There is quite a bit of space in the tunnel we can use for various A/C plumbing and ducting bits.
As a fellow 5 speed 928 owner, EV lover and admirer of Matt's skills, I'm loving this build. Cheers.
Continually impressed by your willingness to tackle the problems that this project puts up.

Coming along well. Really relieved that the loom mostly fits.
Great channel and project from a UK follower 👍👍
Interesting seeing how this comes together.
Thanks Jeff. How'd you like to prep and paint it for me (at enormous expense) in your amazing home spray booth?
@@inCARnationAustralia haha. Absolutely not. I don't even like prepping and painting my own cars ;)
@@HomeBuiltByJeff Ha! I actually LOL'd. No worries

You can twist the CCS cables 180° so they point forward. That let me use this very charge port in my Touran conversion
Hey Stu, a lil bit of work. But how about welding up and removing the existing fuel flap and have the charger behind the rear number plate and have it flip up to charge ? Just a thought 🤔 .
Great idea
Turn the charge port so the cable goes to the rear (bigger pins to the left). You’ll have a lot less issues with short charger cables.
Yes, that would be sensible. But there's no room above the fuel filler recess for the wiring behind the plug - which is a sealed unit I can't easily disassemble.

Could you fit the HVAC unit where the 928 transmission used to live?
Might be too tight there as well, but possibly behind the seats at the expense of luggage space. Or possibly in the front "engine" compartment by the HV battery. I'm pretty sure we can figure out the battery cooling issue but A/C is pretty important in a 928 in Australia with that glasshouse design.

I have no doubt you guys will figure it out. Awesome work so far. I'm really enjoying the series
So is the MG motor bigger physically than the Tesla one?
The Tesla SDU is larger, but it's a much better form factor, with the motor/invertor behind the diff. So it would fit the Porsche better. (I'm guessing we will learn a lot from the first 928 EV8 before we start the second one). Unlike the Model 3/Y motor, and unlike the MG's motor which we had to roll over - they both have the motor barrel forward of the diff.
@@inCARnationAustralia it'd be interesting to see how well it would go with a small Model S drive unit.
I have no doubt it would be a lot quicker - especially top end
For HVAC, why not just cut out the trans tunnel and fire wall to suit? its not needed
The trans tunnel and firewall are pretty integral to the central cage and I suspect they contribute quite a lot to the body rigidity. We'll find a way to fit in the various A/C components but it'll be a slow process. I now want to get the car driving first without A/C and then we can find a place to fit those components. There is quite a bit of space in the tunnel we can use for various A/C plumbing and ducting bits.
A Porsche and Tesla owner.. I can sense smugness
I'm sure the comments section will let me know in no uncertain terms when I'm unbearably up myself
