Are all his parts custom made for his car?
Hmmm, racing beat flanges on that manifold???
fastest car, calling it now.
did i just hear him say he's going to sign 1200 shirts? that one scene from Seinfeld comes to mind
They did a killer job on that ceramic coating, but it won't be enough on it's own. If there's enough room I'd suggest 2 layers of heat shielding with a 1 inch or bigger air gap between them, the layer closer to the exhaust will still get hot but the second/outer layer will radiate a fraction of the heat a single layer would. The more layers and air gaps you have the less energy transferred from source, same principle as room-in-room style sound isolation in recording studios
Get a copper gasket man
I just wanna cradle that turbo too
Just finished it already
Best wishes from Barbados!!!!
rotaries absolutely benefit from a vacuum across the sump space . the number one stupid mod is to seal over the sump vents or to put them both to a can with a vent . this has removed the slight vacuum applied across the sump space in factory setups . those engines will be building pressure in the sump , even the vented can momentarily on down run and when that happens. the turbo doesnt drain oil so well and the rotors dont gravity drain the oil back down the centreplate to the sump. and instead can pass across the control rings to the inlet that is under high vacuum . the notorious puff after boost on engine braking is solved.. was already solved.. by mazda applying vacuum across the sump in all conditions
This man rebuilt a engine in 24hrs, that’s impressive wow
Big fan of the series, keep this shit up. You inspired me to get of my ass and finish my builds
Wtf the ain't a turbo thats a jet engine
Man all this and won't be able to see till December. Ok.😒😜👍
I saw a new aston Martin on the highway and thought it was your rx7. I was sad to see it wasnt, but the silhouette was so close, aston martin designers must watch these videos ;)
Whats up with the C8 haven't seen anything on it in a long time.
Imagine if he finished this build
take the balls out of the exhaust to allow for thermal expansion, they could press into the steel and crack the coating after a while i think.
@Jim Jews around 5:04 you see them
@Jim Jews there are some balls stuck inbetween the exhaust pipes from them being coated and smoothed.
Balls?
I made that meme 😂😂😂
WHO THE HECK DISLIKES ROB DAHM? C'MON :'(
Came back cuz I forgot to like
Bro?! You have to build structures to install anti-roll bars man, cars need it, it's essencial bro 🙏🏼🙏🏼
i wana see your rx7 and the other red 4 rotor go at it...
when are we gona see a race...
I've watched ten vids already and still cannot figure out if this car is made as a pure dragster or track and drift capable also?
Currently posted on a Saturday afternoon begging god for an upload today
the baseball cap says : firing all rotors
This guy. Legend.
I love the 4 rotor but I was really interested in the budget 2 rotor testing projects you started. Any news?
Be careful brother. I be scared of that thing. Even tho it’s so exciting
This was in my recommendations, and it's only 2 _days_ old. Is FIworld broken? I didn't think it would've shown up until March 2032.
What's going on with Isiah?
This car has entered a new level of epicness that I didn't even know existed.
I want to see Rob race Cleetus.
Nice very nice Rob & Crew
man you really forget how yuuuuge that turbo is.
Great job everyone!
I'm going to guess that this is Netflix hyperdrive or something. This build is coming along nicely :)
100% doing world's fast car on netflix
Firing on all cylinders Rob... Not, firing on all pistons buddy..
i love the fact that he took out a LS to drop in a rotary
You are definitely on to something about the "anyone could do this". It helps that you're also teaching us the ways of the triangle as you go! It helps (A LOT) for demystifying rotaries, making them more accessible to everyone who potentially wants to build one in the future. And for that, I salute you!
I swear we can see some gray hairs at the end of the video that I can't see at the beginning. Are you okay Rob?
Shouldn't the driveshaft be coated with heat reflective coating too? Or have a shield between the shaft and exhaust?
Rob better be showing up on Fastest Car on netlfix haha.
That ceramic coating came out dope, you should check out the all black coatings. That's what's on our turbo housings and it's soooooooo sick.
Splines are cut using a hobber most the time. Sometimes a shaper is used depending on the work piece
Can we just acknowledge that this guy still has no car lift
I wish you could know the feeling I get when I see a new Rob Dahm video posted. Your build and content is on another level.
Garret needs to send him a new compressor wheel that thing is still destroyed
Will you ever finish this thing?
THEM POPUPS
YOUR A MADMAN... LOVE TO SEE YOUR CAR MEET MAD MAX'S FD 👀👀👀🧐🧐👍🏼👍🏼💪🏽
Where is the ceramic coated? Is it internal of the pipeline?
I can’t even imagine what the final iteration of this thing is gonna look like
I like the r&d Rob
Yupppp he gonna be on fastest car i knew it lol
Rob have you ever used "the right stuff" gasket maker? It works really good and cures aster than the typical silicone gasket maker.
Ceramic coating is awesome I have had all my cold and hot side plumbing done and 10+yrs later its still the same and temps are lower than before my exhaust manifold was done black the chrome ceramic for extra insulation but has a aluminium look.
The Chevy vibes bring me immense pain... 😞
On a car like this- Im honestly surprised Rob doesnt just install an airjack system on the vehicle
Nah
Don't wanta be rude but wtf are those guys, did those Mexico pulls drag them in. There work is spot on
Have we learned what "the race" actually is? If not I'm thinking This vs That on Hoonigan
Wow a streetable car. Its soo nice.....You know its awesome if ya watch the progress... Hella of a team man. Great stuff
Just me? Holy shit .....Whooooooo Hoooooo ROB
Not yelling now, but will be screaming later 😁.
If you hit 1 million subs will you put in an Inconel exhaust?
So I am into metal fab and have always been pretty mechanical (built a few Trucks, Motocross bikes, my 97 7.3 Diesel and now my 72 K20). My question is for the guys who really know “race cars”. How well is this car built (both mechanically and as far as geometry and suspension go)? I have complete red left for Rob in that he just goes for it and either gets it done or figures out how to get it done. To me it looks like it’s been designed pretty well and ...what are your opinions on the actual quality of this build?
Where is isaiah?
Man goes to extreme to beat younger brother
the only real way to stop the heat is to wrap your exhaust
Glad to see in a world of hack jobs LS swapping boats, you are out here doing revolutionary things. Next level stuff and steady uploads.
Most anticipated content on FIworld 2020/2019
How about a race between Rob rotary vette vs Adam Lz ls rx7🤣😎
Rob did you teach yourself to weld?
i love how rob has all this equip and still works on jackstands ahahsh
Glad....atleast this vedio ended perfectly
It just keep getting better 👏🏼👏🏼👏🏼
Can't wait for his hoonigan autofocus episode with Larry chen behind the camera

Fuck yeah! No sponsor segment!
Should had that photographer help with your lift stability test.
WTF! That’s not a turbo, that’s a fucking jet engine!🤣🤣🤣🤣
when do the 1200hp shirts ship out???
As a professional welder of over 20 years you have no idea how happy it made me to hear you say “heat affected zone” that is proper journeyman talk my man lol. I love to be able to watch you learn and grow in real time. You still suck as a real welder lol but you get better every day my man. (I’m just fuckin with you)
What’s with the 268 on your sleeve?
First dude I ever seen twerk on a AWD FD... Lulz
Rob, when you get a chance ... before and after external temps on the ceramic coated parts would be helpful. Seen plenty of Vendor videos on this but haven't seen anyone who purchased post before and after. Best wishes ...
Where is Isaiah?
Take the turbo off
yes
I am a little worried that Rob seems to be confused about the purpose of ceramic coating... it protects the parts that are coated from oxidation damage due to high temps -- it's not meant as a thermal insulator. I hope he thermal wraps the header and uses a turbo blanket as well, because that coating isn't going to be controlling the engine bay temps like he keeps talking about.
i love you and your build man... inspirational. i always wanted to build a car up form the ground awd rx7 FD with a 4 rotor. you read my mind keep up the amazing work ! wish i could support you by buying stuff but im trying to keep my own g35 daily running haha
Hey Rob are those Snake Bomb Garage headlights?
Meh not a fan of the ceramic coating color.. should of got it coated like a bronze color
Where's the other dude at? The guy that used to weld everything for you. What did he teach you how to weld and then you gave him the boot haha
@0:10 When will he get his own?
Rob gear teeth and splines are carbon hardened after machining, probably you can machine your own but send it out for treating
So ROB? The roof is but attached to the chassis??? That doesn't sound good...
