- Now we've stripped out the Porsche 928, it's time for the MG to go on a diet and start surrendering its intestines to the project. Let's pull everything we need out of the EV and start putting it in the Porsche. But the MG has a few surprises for us - turns out its pretty good at burnouts. It won't impress the crowd at Summernats but it's showed a bit more get up and go than I expected. Hilarious.

There's a lot about to happen with this little EV project.

Fascinating episode ... so many facets to Meg that we take for granted and complain about. It's amazing to see just how complex a modern car is, and Stu, i'll say it again, for someone who doesn't know what he's doing, you're doing really well!
Great project, as an EV fan and a Porsche fan really interested to see how it all comes back together. Good luck.
Good job brother! Really appreciate the discussion on system interconnectivity and network communication. All the little niggling details are what takes the time if you want it well sorted out. Once you yank everything out it darn near impossible to know what is talking to what and what thing needs what information. Keep up the great work. Cheering you on from the endless mountains of PA.
My 88 S4 has a sunroof.... but my 78 928 is a very rare 5 speed manual with NO sunroof. Tons of extra headroom and NO LEAKS.
Awesome series. Can’t wait til the next episode
Stu, regarding your bonnet/hood switch, I reckon they've done it like that so if the switch fails the default will mean the car cannot be driven. Otherwise a broken switch might allow the car to drive with the bonnet open which is something they clearly want to prevent, hence having the switch/sensor there in the first place.
Yeah agree. In a crash, either a short or open circuit on the latch is a fail condition that prevents the car from driving. To one person that's clever safety engineering, to another it's needless complexity. We'll just deal with it.
@@inCARnationAustralia I'm afraid that transplanting the entire MG system into the 928 means a lot of that 'needless complexity' will be brought across and need to be dealt with. I suspect it won't all be as simple as that bonnet/hood switch. 😬
@@UKenGB You'll see me talk a lot about that in the Episode 16 video, which should be released later tonight or tomorrow.
Looking very promising. I just can't believe the amount of power/torque it produces! To get a wheelspin whilst in motion off an ICE, it'll cost you $$$$$ in enhancements.
I had lightened the front a bit by removing panels. And it is FWD. And those tyres aren't the last word. And ... But yeah, it was encouraging.
I suspect that they use a resistance in the bonnet switch so that it’s a fail-safe. If they used it to be closed circuit when the bonnet is open then a broken wire could lead to the bonnet showing as closed when it’s still open. Conversely a short circuit could do the same. A resistor would be much safer.
I came to the same conclusion. From a crash point of view it's in a highly vulnerable place and right next to the charge ports so that makes sense.
The fact you're swapping to RWD and the wheels are going to be wider and bigger, you shouldn't get wheel-spin in the 928. And given nobody in their right mind wants to hurtle round corners in a 928 like they've stolen it, sounds like you're going to end up with the perfect 21st century EV GT car ! Fingers crossed the motor fits.
Yes, agree that the standard 928 has really good traction characteristics. And yes, we'll go to wider tyres so I don't think wheel spin will be a problem. But disagree about hurtling around corners - a few peeps have suggested I'm no in my right mind, but 928s have excellent grip and balance and are heaps of fun in the bends, and don't suffer from lift-off oversteer like 911s of the era did. Fast sweeping mountain roads are great fun in 928s. I'm hoping mine will retain that fun factor and balance.
Im going with 4 hub motors on mine.... all i have to do is remove the engine and transmision and basically change the tires.
It should maintain the 50/50 weight distribution.
Interesting approach. Which hub motors are you using and how are they controlled/coordinated ?
@@martinreynolds8065 I'm actually reading up on a couple different manufacturers. I haven't made a decision yet. But they are all configured similarly. They basically replace the hub just like replacing a hub assembly in most cars. You can actually use them to create a hybrid vehicle by replacing the two non driven wheels on any ICE car.
The ESC is built into the hub as well as the brakes in most models. So the only thing left is a master controller which is supplied by the manufacturer.
Most hub motor manufacturers have two and four wheel controllers.
If I understand it right there is no weight penalty using hub motors because they are on the rolling part of the chassis?
The first car I'm going to try is a two wheel system on a 914. Then add 2 more wheels if I can't get more powerful ones for the 928. But if the newer bigger motors come out, I'll sell the 914 project and get four of them for my 928. I have a roller all ready to go for both projects. I've restored multiples of each car. It helps to be really familiar with the ICE version of each model first. I suppose the biggest challenge will be managing the torque and keeping the wheels from slipping.
I'll edit this post when I decide which motors I'm buying.
It will be soon now. A year and a half in coming I want to have something on order by the end of next month.
Interesting. Best wishes!
@@christopherleveck6835 interesting. My concern would be the increased unsprung weight (and the durability of the hub motor assembly).
I’d be keen to see how you get on!
Take a look at Orbis they appear ti have solved the unsprung weight issue. But they do not appear to sell to Jo Public alas
yeah sure there were no public roads.
