what Belt Driven Starter Generator is that? I have been researching this heavily lately and cannot find out who has solved the CANBUS control issue for these BDSGs and which one to purchase to get this added to my vehicle.
This is the stock part of the BMW i8 (part number 12317649390). It's going to be controlled through the OEM inverter without any tuning (for now) in my i8. I don't think there are many folks out there reverse engineering CAN control of these. At least in the BMW case, the inverter is on FlexRay which is a non-starter in my opinion with the information and tools available today. If I was doing this on another car, Id probably use the same BMW starter/gen, and run it off a $200 Toyota Prius inverter with a control from OpenInverter. openinverter.org/wiki/Category:Toyota The benefit of using an open source solution like this is that you can put a much more powerful inverter on the motor, then output a bunch more power by riding the temperature limits rather than the conservative, drive 200k miles, OEM tune-up. If someone wanted to go down that road, Id consider contracting the design work.
If it's lighter than the existing AWD and get a lower CG, and keep the heavy stuff closer to the center of the car, and improve the steering column and rack, I would also say yes.

It’s incredible to see how much the world-and especially the automotive enthusiast community-has transformed. I grew up in an era when affordable performance parts were limited to just a few cars and engines, and having the right tools was crucial. Today, those tools have become accessible not only to major manufacturers but also to small businesses and even hobbyists. Now, anyone with the passion and the right equipment can fabricate custom, one-of-a-kind parts, making it truly amazing to watch this evolution unfold.
One thing that could bring you more views, is to add the i8 in the thumbnail, because most people won't realise until reading the whole title what the video is about. And i8 is a very recognizable car so naturily more people will click
From a fellow i8 owner, your build is an exciting and super interesting watch! Your engineering and fab skills are awesome, and it’s a real treat watching this come together. Also, if you ever manufacture and sell your quick release + display engine covers, you’ve got one guaranteed sale here 😉
Just found this build and excited to see how it goes. Mechanically the engine mount you made will likely deform the holes in the frame rail over time. Based on how neat your welding is I'm surprised you didn't replicate the original system tbh.
This is the dream :) Thank you for buying e30 parts, I love this exact build, later I would try the GR Yaris engine :) Only dislike I have with the video is the music is masks what you're saying when I'm trying to pick up everything that you're putting down, other than that I'm still subscribing! :)
Synchronous pm deal. The FOC open inverter firmware controls them without issue. A bit more of a tuning curve up front but the process is decently documented, particularly the Leaf motor.
If you ever want to come to Europe and test the car at the Nordschleife I will support you as much I can :) Nice intro and I really like the music + speed of talking!
Such an inspiration! I'm building a mid engine k100 powered Ford Festiva that I hope to make hybrid some day, but I'm not nearly at your quality level yet!
Just my $0.02, consider changing trans mount design to keep a bracket attached to the trans case, those aluminum threaded holes love to strip if you have a lot of install/reinstall going on as you get everything finalized and situated.
The mount doesn’t need to come on/off for much. It could probably stay where it is through final assy. I usually install studs in aluminum stuff that needs regular service.
I'm only here because your Einstar review was recommended after some looking earlier. Now, I am staying for this remarkable, and quite frankly unique build. Any more info you care to share on that exhaust featured in that Einstar video? More sound clips, perhaps.
Because sometimes I have problems following the entire flowchart, am I correct in thinking you are using the starter generator to add power into the crank rather than the an electric motor at the wheels? I presume this is all just to adapt the SG to the 13B in order to use it with the factory components? Thanks
Love your vids and admire your skills man, but the music was far too loud in this mix. My personal preference is no music when people are talking but I get others are different, but it's objectively too loud.
Were you planning to build more or a kit for I8's? I would love to buy one just to do this. My dream is a mid engine and rotary, this seems to be the ultimate build! Good luck!
I'm rather concerned by the lack of clearance between the downpipe and the transmission case; what are your plans for insulation? In-industry, we traditionally do a multi-layer metal heatshield with air gaps on both sides, but obviously you don't have enough room for that. Maybe it's just an optical illusion from the combination of shadows and the footage being slightly-out-of-focus, but it looks like you hardly even have clearance to wrap the pipe. When designing the pipe, did you consider locally ovalizing the cross-section between the v-band and the O2 sensor to gain more clearance? I imagine it would be a lot easier to achieve that with a 3D-printed part vs. if you had to try to fabricate it out of round tubing.
Do you have any extra support for the front of the eccentric shaft? 13Bs don't like high shear loads on the front pulley and will eat up the front bearing very fast. There are a couple solutions out there though from people that have supercharged them
Mitch Abbott on IG sells the models. Each main part fits onto a creality CR10, although a bed slinger printer is a terrible choice for such a big mass. instagram.com/mitchabbott_?igsh=Nmd3Zmg3eng2Z3N5
Polyurathane bushings dont suck on a street car... Overly stiff poly bushings stuck.. and most aftermarket ones are overly stiff. Some from being too high of a durometer, others are a fine durometer but made solid in a situation where there should be holes to give. In otherwords, as a material, its superior... but due to the poor engineering of the aftermarket, it has a bad rap. OE generally doesnt use it because of cost & tradition...
Yea most aftermarket offerings are too stiff. If you choose a softer durometer, there’s likely marginal improvements over fresh OEM rubber. Arguably perhaps get some better longevity. My comment is mostly around RWD style mounts. FWD stuff with open cavities in the rubber definitely benefit from poly inserts.

i have a bosch 20kw one on the accessories belt and have found no other solution save for a standalone programmable inverter.
@@riccardo1796What is the part number of this? Interested in having a look
@@CouchBuiltDoes the stock inverter not require feedback from the engine controller to operate properly?
It does. See earlier control episode
I love this! My brother would beg me to do this to the awd 4 rotor and make the front wheels electric
Do it! Happy to help make it happen wherever I can 👌🏻
If it's lighter than the existing AWD and get a lower CG, and keep the heavy stuff closer to the center of the car, and improve the steering column and rack, I would also say yes.
Thank the God's for given you the brain's not do such things to the awd 4rotor rx7. 😅😅😅
The amount of engineering in this is absolutely nuts.

Yea funny yo think not that long ago that not wasn’t in a Summit Racing catalog, it was unobtainable for most.
That is such a beautiful sight! The I8 is not an ugly car and you have made this car into a proper supercar! It should have came this way! 😀
this deserves much more attention, inspiring stuff

Best Build on RUclips,
Your Film making skills are improving and i hope you are having fun doing it!
Looking forward to the custom CAN display, would be great if you could go into detail for people who would like to follow along :) Loving the content!

This subframe isn’t going in the car, I’m only using it for mockup. Worst case the plate gets welded on the real subframe.
This is the dream :)

Seeing this build in action. Usage of 3d printed metal parts has been great! 👍 ❤
Fantastic work. Loving this project
Excellent 🍻 I don’t understand how this isn’t viral yet 😎
Great job, i really like this build, seing you using send cut send gives me so many ideas for my projects
I’m am loving your build, incredible work and I’m in awe of the results!
PS, I loved the hard rock track in this video, made me want to rock out! 🤘
What a cool unique build that I have stumbled on, subbed straight away. Cant wait for more vids to follow this build!
crazy build, amazing videos... deserves a lot more views
Instantly see him rocking the Teckademics👊🏼😎
Hello fellow old car enthusiast
Ackshually, the motor is technically an ac synchronous, not ac induction. Failed to catch that misclassification during editing.
As in a bldc or an actual synchronous reluctance one?
Because if the latter, good luck with getting it to work with off the shelf controllers
Synchronous pm deal. The FOC open inverter firmware controls them without issue. A bit more of a tuning curve up front but the process is decently documented, particularly the Leaf motor.
@@CouchBuilt nice
Yeah, FOC for PMSMs is very mature at this point
You are just a hero! What great content you are creating! Only the hard music could be a bit less
This is an awesome project!!! Can’t wait for the next episode :D
Nice and constant work on one of the must exiting build out there. Congrats!
Thanks! Gotta keep moving ahead with how many things are left to do.
Love it. Bad Obsession Motorsport with computers.

It might appear that way, but loads to go.

It’ll have an inconel heat shield. It’s also not rotated to its correct position.
Where are you sourcing those large rubber motor mounts from?
