@@Belicose777 Lighter, stronger, prettier. Dahm said he will build a full billet 2 rotor first. Then the 4 rotor i hope. If i remember correctly, the 4 rotors current engine is the one he is gonna run until he can get a full billet 4 rotor.
I predicted ages ago that thing will never make it to LS Fest. He might know a little about rotory crap but from what I've seen his fabricating skills are lacking.
Rob, that belt is going to hit the crank sensor mount. Belts vibrate and oscillate at various RPM harmonics. You may want to consider using the really easy solution that is available to you, use the FC crank angle sensor option. This would eliminate of failure here. Nice project, can't wait to see it done. Good luck!
Man, I love modern CAD-assisted machining! So easy to visualize things, plot them out in your CAD program and just transfer the whole thing to the milling machine. Wish life was that easy when I was in machine shop 45 years ago! Great setup and looks like a nice clean, trouble-free solution. Great video Rob.😁👍
Another reason to go rotary: you can carry the engine in anything. You’re having the same issues with your input shaft sleeve that I am with mine. Glad to see I’m not the only one that says to cut it out! Can’t wait to see this thing under its own power!
Short serpentine belts without a tensioner will flap the non drive side & it will probably rub on your crank trigger bracket. Carry a spare belt & keep an eye on it.
I love the Dahminator! To clarify for your terminology: The slave cylinder setup where it's in the bellhousing and part of the throwout bearing is called a "concentric slave cylinder". I know that to be an industry standard term that universally applies to people work both in OE and aftermarket, regardless of the brand of car or platform.
Is rob sandbagging and showing us thay things are further behind than they actually are? I hope this was days ago cuz there's only a couple more days till the car needs to be there. And hopefully it drives in and doesn't sit there without running or running without driving kinda like the 4 rotor at sema. Im really wanting this to happen but in this video there's still a lot of work to do hoping there's no problems that prevent it from working like it does in his mind.
In the last video, not the livestream, did Rob not say they were going to Abel 'tomorrow'? That video was two days behind the date of recording, based on title being '7 days to LS Fest' and commentary in the video being '9 days', which means it was recorded on the 24th. Which also means this video was recorded on the 25th, which means this video is almost a week behind actual progress. Not a patreon, but you can still view video titles, the 30th had a video named 'Almost ready for first test fire', which means the car is close to good enough for LS Fest. It's basically ready for LS Fest if it runs, and all of the ecu trickery actually works.
this video was done 2 days ago likely. what are the chances he got it running in time for LS fest this coming weekend? my guess is its going to LS fest on a trailer.
Today's dahm Instagram story says "let's just say some purists just felt a disturbance in the force." so I'm definitely thinking it's further along than we're led to believe here
rob you oughta have him make a protective shield/cover for that crank sensor on the front cover too. i'd hate to see what happens when a belt rips at 10k rpm and smacks that crank sensor assembly somewhere
Hey Rob, this is my first one actually having a change of you reading my comment. Anyways you are a really big inspiration to me and I love all of your videos and work that you accomplish. You are very funny. I find your videos very entertaining and educational. Hopefully when I own an Rx7 of my own I can put what you have taught me to work. I hope you have a great day. So long
Rob Dahm is the type of guy that makes simple things not so simple. Wouldn't doubt if you're getting a drink of water at his house, it requires you to give a blood sample to see if you're really dehydrated.
I’ll be a miracle this car gets done. But at least he bring the car and aaaaallllll the parts he got for this build for LS FEST. And show everybody his dream was.
Pretty sure this was filmed a few days ago because he just did a live stream a day or so ago. The engine was already back in the car and he said that the Corvette was about 2 working hours away from starting. Then he hinted on his IG story yesterday I believe that it started for the first time by saying “the purists just felt a disturbance in the force”... I think he’s messing with us.
You machined your reference out of the bell housing with out shooting some dowels first, how are you going accurately locate the two together now? Just the input shaft?
If you go gaga over a Fadal, you should see what we've got. It'll make a rotor housing to within tenths all day. I've even got the proper equation to make the trochoid.
Is the tone ring the same between fc and fd? They have different ignition timing, split and physically the spark plugs and intake port locations are different
Personally, I would've rotated the sensor 90° down to the front brace that holds the engine mounts. Why? Simplicity. When you move the brace in assembly and disassembly, the sensor goes with it, and you'd never have to touch the sensor again except to plug and unplug it. It also gets rid of the bracket sandwich on the side of the front cover, which again, simplifies the assembly and disassembly process. And because of how high the front brace sits, you can go from the assembly of two brackets, two standoffs, four screws, and mounting bolts, to an assembly that could easily be one bracket and mounting bolts; smaller footprint and less parts. And because of where the sensor is, you can easily cut into the brace without sacrificing a ton of, if any, structural integrity.
When Rob put the glasses on, he becomes *Robert Dahmned* 🤓
So glasses + goatee and dad clothes = Bobert?
its like clark kent---super man.
Honestly, he looks like Gordon Freeman.
Add crybaby drama
There’s two versions of Rob... Glasses wearing engineer Rob, and then the normal “hell yeah brother” Rob
Engineer by day
HellYeahBruthr by night
Rob is not Cletus McFarland
Cletus got it from Rahb 😛
dont forget Bob Dahm
Rob is Dorito Cleetus. That is fax
Hope you finish the 13B corvette before LS Fest.
We all do....expect LS guys maybe
@@beflix8140 except,not expect...........
It will never be finished like his “4 rotor rx-7”
He will just be working on it forever and will keep saying it’s almost done
@@beflix8140 Why? This car will get destroyed by every LS powered car at the LS fest. This car is a joke. It is a gag, not a fast car.
@@berrytharp1334 it really is a joke.
Bro this is why I subscribed... this video was so interesting. That guy who helped you make the parts is so cool man. Hope to see more of him.
The CNC machining guy is very talented, full credit to him.
Straight up, he's a dead set legend!
If the corvette can’t make it just take the Honda Insight
With it's banging system...
I wish the 4 rotor would've progressed this quickly. Thanks UPS.
Ups dicked him good. They put his build back a good 2 years.
@@hamsterwolf 2 years? He just got the chassis done but not even floor pans yet. Put him back maybe a few months at most.
@@joshua_J when ups lost his 4 rotor it was gone for a long time and all the money and planning that went out the window because it he probably would have finished the 4 rotor already if someone at ups didn't try to steal it.
if rob doesnt finish this for ls fest it will become another 4 rotor deal and he can get roasted more and more
The 4rotor is having a billet engine built

Goddahmit Rob!! 4 rotor needs this kind of effort
Looking good Rob. Looking forward to this coming to life.
The world needs more rotary corvettes
I love machining, happy you showed it!
That dude was taking a helluva cut with the CNC! Well done!
Best episode you’ve had in 3 years! I’m excited for this to make it to LS fest
Nice to see you guys actually came up with something that can be used for other rew setups!!!
when he lifted the rotary out of the car my first thought was if the strap slips off the fork they bounce up and go right through the rearwindow
The hours that go into a project like this, brave man rob
rob you oughta have him make a protective shield/cover for that crank sensor on the front cover too. i'd hate to see what happens when a belt rips at 10k rpm and smacks that crank sensor assembly somewhere
A truly prophetic statement

Rob Dahm is the type of guy that makes simple things not so simple.
Wouldn't doubt if you're getting a drink of water at his house, it requires you to give a blood sample to see if you're really dehydrated.
I can’t wait to see it finished
seeing Nader makes me happy
Rob that is the most amazing machine I've ever seen every rotor head should have one or at least access to one. Amazing!!
Rear mounted pulley drive on the diff / trans axle would remove the alternator from the engine bay altogether
breathtaking performance.
Your doing great Rob! Keep up the good work and content.
Thank you mr.rob for leading the way with this swap. I hope to be the second person to have a rotary corvette once you're done.
Pulling them glasses off for dramatic thought was terrific.. Good luck man this is cool.
I wanna see this car running for ls fest !
12 hours left till LS fest, man do i wish to live in America ...
When you wear those glasses it reminds me from the movie Turbo when Tito tries to get into the F1 race.
People with kids we'll get this
Cleetus McFarland posts a video leaving for LS Fest. Rob posts a video still figuring out how to fit the engine. I see no difference
Cleetus is annoying as fuck
@@josephbrady711 Cletus actually builds fast cars that run.
@@berrytharp1334 Rob built a 3 rotor, ctsv. Also the 3 rotor is over 200k so i dont see cleetus having a build nearly as complicated and as much money
Austin shupe let me know when Rob runs a stick shift into the 7’s.
@@josephbrady711 why is he annoying? I like both
Do want to see the insight rear engined with the 13b! Love the project Rob, keep it going! :)
I know they have a CNC, but that day the fork lift was the most useful tool in the shop!
What your doing is nothing short but Amazing
13b swap insight confirmed
Why doesn’t he just use the distributor hole for the modern timing sensor? That would solve his problems
I love seeing all that machining goodness 👍🔥🔥🔥
Roadkill it up and run no alternator at all
Wojciech W. Yes
just strap a diesel generator to the roof to charge the battery
So easy to make a bracket to change the orientation of the crank sensor, maybe relocate it to 12 or 9 o'clock.
MBN having badass connections
Horatio Caine "CSI Miami " it with the Jim Carey twist, I'm talking about the glasses 😂
First dorito swapped vett and insight, lol nice
CKP in danger till the engine stops.The mount was great.
Rob Dahm is like the Rotary Superman with those glasses. Nice Clark Kent disguise Rob!
I’ll be a miracle this car gets done. But at least he bring the car and aaaaallllll the parts he got for this build for LS FEST. And show everybody his dream was.
In other words.... your not making it to LS fest. Damn Rob , I was rooting for ya! Much love from Madison Heights , M.I

love you rob dahm
god dahm! those parts are a dream
That printing machine is so cool imagine printing a custom design engine from it
This is gonna shred some belts
I dramatically pulled off my sunglasses when I picked up my 13b last week and wondered wtf I got myself into hahaha
Life is good, life is very good 😎

People are starting to leave for Ls fest today.....good luck.lol
I Really hope you make it to Ls fest on time!! Keep going and stay fyckin awesome
new game - drink a shot every time Rob takes off glasses dramatically ... ;)
Thank god people like built to apex exist
rob u are not an engineer u are a meme-man tho
BRING IT TO SEVENSTOCK!!!!!!
Rob with glasses= the guy whe engineers the engines. Rob without glasses= the guy who does the reliability testing lol
Is the tone ring the same between fc and fd? They have different ignition timing, split and physically the spark plugs and intake port locations are different
Dam dude your going where no one has gone 👍🏻🇺🇸
Rob ive always wanted to see a rotary in a vette.....keep going bro and thanks.....work on getting the car fully sponsored
When rob puts those glasses on, he turns to Professor Dahm. Kinda like how hulk turns to professor hulk
Love this build!
If you ever don’t want your insight, please let me know!
Man I been waiting for an upload like dope head for a dealer!
Multiple robgasams ahead boys
"its pretty close to almost not fitting" haha
Icky sometimes I just talk too much lol
Why is Dahm flexing so hard at the 3 minute mark 😂😂😂
Hey Rob. Love all of your videos.
God damn it always leave me hanging!
A fillet rounds a corner to a specific radius, a chamfer basically cuts a corner
Epic looks so cool!
Personally, I would've rotated the sensor 90° down to the front brace that holds the engine mounts. Why? Simplicity. When you move the brace in assembly and disassembly, the sensor goes with it, and you'd never have to touch the sensor again except to plug and unplug it.

jam a rotary in the insight, add psi until it runs 10's.
Wowzers.. Just epic
I think Rob Dahm needs to become and actor
Make the sensor mount part of the alternator adapter.

I vote you get a nice RePu and 13b it for a truck.
I would go w a slightly shorter belt
Gorgeous!
