Please no spoiler at the start of the video. I want to see the problem solving and creative thingking and only after that the results. 😃 You don’t have to be like other youtubers, you are better than them.
This kind of engineering is amazing! The whole premise of being able to print this at home is fascinating to me! The looks of it is amazing as well. Why hasn't someone made something like this as a replacement for the antiquated 964 system?
Why not make a bracket that prints with the orange bottom pipe and keep it close to the vacuum can. So hose will go straight from vacuum can to solenoid to dashpot in a linear fashion.
That’s an interesting idea, thanks! I was also looking at integrating the vacuum lines onto the tube itself. That ended up being some extra material through…
Fantastic engineering. As a newb, I'd love to see a video on how you integrate a drive-by-wire throttle body into an old air cooled engine with the throttle maps in the ECU. Are you planning on touching on that?
I did the same thing on my 3.0 SC! Found an old 993 plastic intake, shaved the plenum for a tidy appearance and EFI'd her. Using a diesel swirl valve actuator to control the resonance valve. But I kept the stock throttle linkage, which wasn't that hard to adapt. Nice work and keen to see the results on the 2.7!
A pretty tidy outcome. Gotta love 3D printers 👍 Due to my OCD I would have to mount the vacuum reservoir horizontally. Being vertical just sets my twitch off 😅
I'm a fan of carbs, but its like you say, if it takes the attention away from the other car its not worth it. Glad I'm not the only one with multiples projects of the same car ;)
@@islandworks they do indeed look great as usual Jonas! The E-ITB is a nice way to get rid of the complicated IACV etc and at the same time the 964 intakes will flow better as well. In order to fit them to the older heads you need some new intake runners, right? It seems like you also have them ready already in orange… 😎
Lovely design process. For the vacuum tank, could it have been rotated 90 degrees with a bracket off the balancing tube to minimise the length of vacuum lines and tidy up the plumbing? I can understand wanting to use the standard vacuum tank, but just interested if you made any other considerations before getting to you final design? Great video, keep them coming! Stephen.
Awsome, Stunned to the details and engineering skill you show. One thing tho - would it be possible to print the whole intake, since you had it scanned and all?
I have a design for this that I was toying with for my other 964. It looks awesome and opens up some more design possibilities. It’s also quite heavy on the cost due to the process you need to apply
Excellent video as always, good Sir! Out of curiosity, was there any consideration given to using an electrical servo actuator for the blend flap? Given that you are already going to an aftermarket ECU to manage drive by wire throttle etc, I know that some of them offer a switched output that can be set by engine RPM for example to trigger systems like this. Could theoretically eliminate the need for the vacuum system if the blend valve were the only thing using engine vacuum, though I don't know if that is the case for you or not. Either way very cool project, and I hope you post a video of the end result :)
WOW very nice. I’m wondering if replacing the throttle blade from the resonance tube with another DBW throttle body can do the same job and can also be controlled by the ECU for even better control 🤔
It will add a bit to the weight of the system as they are quite a bit larger than the vacuum system and requires two more H-bridges for actuation in the ECU. I would not go that way to be honest
Great work 😊, are using 996 pedal or connecting cable to to the electronic DBW control box. I do the same and puzzeled to fit the 996 pedal or use the original. Cheers
When I converted my bike from carbs to electronic ITB I used printed parts as proof of concept but I didn't have the guts to keep them and had CNC stub intakes made. But if I had PA CF available maybe i would go for it. What ECU are you going to use? I used a MaxxECU sport and I'm really happy with it!
With respect to the vacuum reservoir, why not simply redesign the lower intake runner to incorporate the vacuum reservoir yet so look like a single runner. You could hide the bulk of the reservoir behind the lower runner that way. Also, whilst you are doing so, hide the vacuum switch behind it all too. This will keep the engine looking very clean.
Great stuff, i've been following your 964 build for a couple years now. As an individual who tracks his cars, i was wondering if you had an opinion on the front cross brace that porsche motorsport ran on their 911 race cars in conjunction with the front strut tower brace. Elephant racing sells one. Yay or nay?
Thanks for watching! I’ve only tried the brace I have (and now modified). What I do know if that without a brace the whole body in the front will move…
That’s interesting feedback. I’ve done quite a few of the 82mm for 964 type engines and they got good idle performance with that one. What would you see as the down side with a big TB?
@@islandworks The downside, hmm. Well It's larger than it needs to be, wasted expense if that is a concern, takes up more space than needed, inlet piping larger than needed, heavier than needed, Max power is probably achieved well before TB is wide open, less linear power increase as throttle opens. It's less of a downside to go larger than it is smaller, it's just that people often go far too large thinking they will make more power. For a six cylinder the throttle only needs to be equivalent to two valve inlet ports.
@@chippyjohn1 Thats great input thanks! I found that it makes a big difference on plenum since and geometry on the inlet. Bigger TB makes all of that easier as well
@islandworks A larger throttle body does mean reduced intake velocity, so it may lead to better flow at tight angles. I enjoy your work. I am working on a manifold, but for a helicopter so trying to shave every gram and make it as efficient as possible.
you're a wizard Jonas
Thank you for all the great comments. It helps me and the channel to grow!

I love the comment ❤️
Just learning by trying!
Agree. Channels can be themselves, works long term
It looks much simpler but cooler than the original one! Very nice! 👏🏼
I like it ❤️
Damn thats clean.
Thanks for this - giving me ideas.
I designed & printed ITB intake manifolds for air cooled VW heads, using CF Nylon. Handles the heat with a phenolic gasket.
That’s awesome!
This kind of engineering is amazing! The whole premise of being able to print this at home is fascinating to me! The looks of it is amazing as well. Why hasn't someone made something like this as a replacement for the antiquated 964 system?
It’s brining it a few decades ahead in possibilities for sure!

That’s great! I really like the DBW setup myself. I’ll post the result later on!
I'd love to try DBW one day, perhaps on the next build. The ECU I chose did not support it. Cheers!
Ska bli kul o följa!
Absolut!
Killer engineering!
Killer fun!

I know what you mean… I just made that change yesterday…
Nice job, looks great! Thanks for sharing. 🚙

Great video as always mate
Glad you enjoyed
like it so much, willing to buy one
It turned out great! It will be in the webshop eventually.

Yes indeed! I do however find a single TB more appealing as a matter of opinion.
The intake runners are going into production and will be here soon 👍

I have been looking for a different tank, but not found a good alternative as of yet. The 90 deg would also work!

Great work 😊, are using 996 pedal or connecting cable to to the electronic DBW control box.
I do the same and puzzeled to fit the 996 pedal or use the original. Cheers
The easiest is to use a 997 pedal. I need to create an adaptor for that as well…
@@islandworks do you have a video on the pedal solution yet? I will be installing a 3.6 in my g-body 911 and I am really impressed with your intake.
@@jakubbobkowski8615 we have this and offer it together with the intake kit. Send us a mail and we help you out

What ECU are you going to use? I used a MaxxECU sport and I'm really happy with it!
For this 911 I was planning to find an ECU that I can fit into a casing that looks like the old CDI housing. That would help blend it into the rest.

You could hide the bulk of the reservoir behind the lower runner that way. Also, whilst you are doing so, hide the vacuum switch behind it all too. This will keep the engine looking very clean.
That’s a good idea! I was trying several different versions and it might be an opportunity to do something more

Would you consider selling one of your intakes its for a stock 94M9643.6 ? I really enjoy watching all of your videos.Kevin
Absolutely! Check out the webpage islandworks.one
Is it exclusive to your car only or is it actually a product available for purchase?
I’ll put it in the webshop if anyone is looking for the same

The 65mm throttle body would be more than sufficient for the larger engine. People almost always oversize their throttle bodies.
