Rob explaining the turbo being out of steam reminded me a lot of Gale Banks explaining turbo efficiency on his channel. I really appreciate the technical aspect of how/why you can/can't make power
@@RobDahm to say it was hilarious, is a massive understatement. 🤣. Your 3-Rotor has got to be the best one I've ever heard, and i bet the video doesn't even do it justice.
He's talked on that before with the 4 rotor being so much more expensive if something goes wrong and that's what causes his nervousness, also the fact his elbow is a few inches from the driveshaft it just gets scary when doing a dyno pull.
Saw you at Shift Sector and this car is nuts, absolutely one of the coolest things ive seen. Cant wait for the next project, its gonna blow everyones mind
I love these videos because there is no stupid, long intro or outro with flashy graphics, no "hey remember to please please please subscribe, comment and like all my videos, blah blah blah", he gets straight into the meat and potatoes, and then the video is over. Love it!
I think one of the best people on the internet when it comes to explaining Horsepower, Boost pressure, manifold pressures, etc. Is the legend Richard Holdener. As soon as you started explaining the PP and how it’s allowing more air flow, it clicked in my brain because of him. Anyone interested in motors, definitely needs to check him out. Good guy, and mad scientist. Glad to see the 3 rotor puttin in some work. 💪🏻
Every time the Fabrication Father appears in a video i realize how much ive missed him the last few vids. The chemistry with the Spinny Dorito Man is just out of this world.
literally watching freaking out that a piece of insulation was gonna get sucked through the turbo. what a weapon though. absolutely love watching your vids as you have been learning over the years and sharing honest knowledge you have gained. Bloody legend.
Your comment about Boost Pressure being a greater indication of intake restriction rather than a hero number was well timed. Engine Masters on Motor Trend JUST did an episode about this earlier this week or late last. Less restriction=lower boost pressure (with the same blower/turbo setup) but the total air flowed may actually be the same or more as a higher boost pressure did with more restriction.
I have a bit of experience tuning a single cylinder, single stage fuel injection system using injector pulse timing. I can only imagine how insane it must be to do it with three rotors and dual stage injection. You are a good tuner, Rob.
Oh baby, more 3 rotor, let's go. This arc is just super inspiring. I want to now just how much of the rotary Rob is planning on building / re-engineering
1. Anyone else start seeing whether the ceiling pieces were going to float into el turbo? 2. Rob, this car sounds beautiful man. They make vids for calming music... Ever think you should drive around and record, haha
I love that Rob is still a pretty boy with alot of brains behind it 10/10 would love to come see it in person 👏👏👏 keep it going my guy! You're Killin it!
Man i've been watching your videos since you first started with the Diablo stuff. Close to the time you had the video of this car on the trailer shooting huge flames. As much as I love the 4-rotor videos, i'm glad to see this thing back!
I gotta say a 3 rotor FD is probably my dream street car. Nothing this crazy (I want something I can daily semi reliably after all) and maybe half or a third the power... but the sound of a well balanced three rotor is beautifully smooth
Older video, also just re found your channel after my account got yeeted. Love the stuff. I watched Banks power a ton, and he gets into a lot of technical aspects. You can have super hot air, and ram all the pressure in it you want, but where it shines is when the air can get in there, prefferably as cold and compressed as possible, and then give it all she can take. Obviously you know this, but just nice to hear you talk about it. People running 40 50 60 PSI on some engines, (with exceptions) you gotta wonder if they're doing it right or just slap a huge turbo and go.
Anyone else notice the super cool helmet the front passenger was wearing about 5:30? If you pause it at the right time, is has a sticker that says SOLD 2013. And it looks it. It's crazy an only 8 year old helmet with 8 year old decals can look and feel so nostalgic.
Awesome work! Noticed how small your exhaust is, I think that is the key factor to the turbo failing the top end. Always see problem with turbine efficiency when post-turbine backpressure rises usually cause the tapering off up top. Noticed on the 4cyl saab at 650whp we find absolutely 0 backpressure at full 4'' combined with single 45mm wastegate with atmospheric vent takes drastic leaps in efficiency. Especially as backpressure post-turbine multiplies with the current pressure ratio of the turbine housing so end up elevating the exhaust manifold pressure so clogging up the chain more. Automatic drop in volumetric efficiency as higher pressure gets trapped as the rotor transitions over to intake port or intake valve opens so harder to get the air/fuel mix in so in the end more waste of fuel as you overspray the ports for same result and inconsistent burn. Always this ongoing pressure balance through the engine, that's where I have found the most power every time.
Funny how you start to notice a lot of these youtubers/youtube channels being in the same place at the same time, Donut Media shot their video with the Altima here too
Get one,you can pick up an RX8 for not much money. I would go for a car from the warmer states if you're in America as the RX 8 is prone to rust on the wheel arches,sills and boot/trunk lid around the 3rd brake light. I love my RX8, I chose it over anything else I own in the summer months.
I spend too many hours dreaming about a 3 rotor FC maybe someday the stars will align and I'll get another one and build one, even better with your guidance.
i think you missed out on explaining something here rob, regarding the swapping of the corner seals. alot of the audience might not realize what it means to do something like that, plus the fact he was able to do so was mostly due to the early life span of the engine. but yeah Rob had to pull that whole engine apart and rebuild it. based on the video he did it in less than a day
SOO FREAKING AMAZING! The last big 3 rotor video I remember was the wine maker 🤣 but these beat that by a mile keep it up! Now just waiting for what comes next, strap-ons maybe?

Rob is the walking definition of "If you want something done right, you (learn to) do it yourself.
@Duner250R Not true. But most people are capable of far more than they think, if they put their mind to it.
that's me right now working my build for my custom motorcycle, the difference is i don't have that many tools in the garage yet 😂
Couldn't agree more!
Couldn’t have said it any better. His videos motivate the hell out of me every time. He’s a smart ass man.
Or eventually learn after the 14th failure!
His hair always tells you if he slept or not.

And his tired eyes 🤣
Can you please explain further?

Thanks to keeps we know if he slept or not
That escalated quickly!

Sounds like a good time.
So, you had it pegged?
14:10 watching shit flying around that open turbo is stressing me out
Same! Get a bug screen for it.
I was about to comment the same thing, came to see if someone else already had....yep.
Not again not again not agaaaaiiin

I love how we get extra content in every video, without being mentioned in the title, Rob is so humble
That run to the altamaniac was horse girl vibes but it’s totally understandable. 👍

And they often attract each other. Ask me how I know.

That is what you call dedication

Bed? He sleeps where the cats allow him.
More like addiction
Hey Rob, hope you are doing well! I’m so excited for this 3 rotor series, Keep making the awesome content I love the vids! Stay safe. Thanks.
anyone noticed hes not nervous on the dyno anymore? Hes learned well.
Knowledge doesn't alleviate nervousness. Confidence does. There are plenty of stupid people with way too much unjustified confidence
@@Dr.Spatula But knowing you have increased your knowledge does increase your confidence.
@@sensoryoverload673 circumstantial. Having more knowledge could increase nervousness since you understand what could go wrong if you fuck up better
He's talked on that before with the 4 rotor being so much more expensive if something goes wrong and that's what causes his nervousness, also the fact his elbow is a few inches from the driveshaft it just gets scary when doing a dyno pull.
@@MrDelsoleg11 yeah, the 4 rotor is like a 100k for a mistake lol

Are we not gonna talk about the Indy car parked under Ahura at the end of the video?
That’s where the 6 rotor is going! 😂
Apparently not
@@alastairlrobinson I don't think that's even remotely close to fitting, unless Rob wants to stretch that indy by a foot or 6

Marty Car Mods reference. Old car parts "IN THE BIN!!"
It's DAHM good to see Isiah again in the videos!!!
So we just going to ignore the open wheel formula car under the 4 rotor at the end?
Yeah seen it too. He is either storing it for a friend. Or it the 6 rotor project? Lol. Be a awesome 6 rotor swap candidate
Glad I wasn’t the only one who caught that!
Was wondering the same thing. I also didn't see the C8 anywhere... is that still a project?
That's exactly what I noticed. At first I only saw the "Foo" on the rear wing and though, "Does he have an old Footwork F1 car!?!"
@@GregoryVeizades it says “Food 4 Less” it’s a grocery store lol 😂
I honestly cant believe how far that car came so fast and it sounds amazing
Yea. I been planning to sell my house and buying one... I just cant
Idk whos doing the cameramaning but it’s such an improvement!

So are we going to talk about what's under the lift or pretend like we didn't see it Rob
He liked it 😳😳
bro.... holy fuck
Oh wow, yeah. full on
Right! Had to find the comment, thought I was the only one for a sec😂
Time stamp?
3 rotor finally getting revenge after years of getting his parts stolen for other builds
Rob “I am beyond exhausted” Dahm
My anxiety when that debris fell into the engine bay, with no filter on the turbo. My heart skipped a beat
Yay I thought no one else was going to mention it!! You see that recent clip/tiktok of a turbo eating a banner and blowing instantly?
I'm not on tiktok so not but have seen something similar
Yes but that was one "bad turbo " that ret needed to get rid of
Isaiah is such a character, the bromance still strong
literally watching freaking out that a piece of insulation was gonna get sucked through the turbo. what a weapon though. absolutely love watching your vids as you have been learning over the years and sharing honest knowledge you have gained. Bloody legend.
22:02 Can we talk about the elephant in the room? And by Elephant I mean the fricking F1 car under the 4 Rotor???

Less restriction=lower boost pressure (with the same blower/turbo setup) but the total air flowed may actually be the same or more as a higher boost pressure did with more restriction.
Super cool to meet you this last weekend. You’re an awesome, genuine dude with a killer team Rob.
was getting nervous by all the junk flying in the room while doing those pulls, didnt want anything getting sucked in the turbo
I can't wait to see you run this and the 4-Rotor back to back on the Air Strip. Take home 1st and 2nd place on a half mile weekend
It’s really cool to see how much Rob’s knowledge has grown over the years. Just thinking back to when he got the Lambo to now is really admirable.
This is for me....the most informative vid I’ve seen in a long time....dyno session commentary very nice.....soundstage on load...?...good work gents👍
Isiah ain't playing around and straight to work. Love how the kid is a positive influence on Dahm builds.
That is the cleanest BRAP i've ever heard,it's just perfect in every way.
Here i am at 1am... watching a Rob Dahm video.
Good morning
Just finished watching it and the clock is 01:48 but at least we get more sleep than Rob
@@hampussandstrom414 what part of the world? Im in central usa and it's 706pm now
3am here lol
England, 1am
11:58 I was expecting that paper to get sucked into the turbo lol

Boost is just a measurement of resistance to flow. A ported head will typically show less boost than a non ported one, less resistance to flow
@13:20 ish your talking about the difference between CFM and Boost PSI. It's all about the CFM of air flow.
That car going down the street in the afternoon sun was a thing of complete beauty.
Love the videos Rob .
Dude your in the altimaniac and Larry Chen’s following you in his Supra that’s bad ass
I liked seeing Larry Chen that animated hahah he is usually keepin it super chill. Nice progress Rob!
1. Anyone else start seeing whether the ceiling pieces were going to float into el turbo?
2. Rob, this car sounds beautiful man. They make vids for calming music... Ever think you should drive around and record, haha
good on you for explaining what the real meaning of "boost pressure" is. 30psi and 30psi arent always the same.
Engine masters on motor trend perfectly explains "boost VS. flow" this week. Great point to bring up.
I love that Rob is still a pretty boy with alot of brains behind it 10/10 would love to come see it in person 👏👏👏 keep it going my guy! You're Killin it!
Isaiah always saving Rob!! 🤣🤣🤣
Happy that @fabdaddy is back again!
damn you got to get a ride in the Altimaniac?! I saw the video about the car & it included that ride along in it, but I had no clue it was you.

And he is using science, asking the wright questions and comes to genious conclusions. 😎👍
I pulled an all nighter with my newborn and thought I was sleep deprived but Rob made me feel wide awake. 😂
Hang in there buddy. Sleep deprivation is no joke
My favorite youtuber getting to experience drifting, hell to the yeah brother! 🏁
That open wheeler at the end tho 😳
Whenever I see the 3 rotor it always feels like checking up on an old friend and knowing that he is doing better after hitting rock bottom
Wow that 3 rotor rips! Cant wait to see it getting raced hard! That formula car looking good in the back..👀👀 love from Holland
Hell yeah Rob. Keep expanding that knowledge base and pushing the limits.
As excited as he is, this man is still safe with all his decisions. Mad respect my guy. 👍🏽

I know the full bridge is a big difference over a big streetport.. and the idle sound is just wonderful
If things worked the first time it wouldn't be a rob dahm project. We still love you and the 3 rotor! Cant wait for the new Corvette
My Rx8 photobombed once again.
Good shit Rob. Tuning is a whole other game and you’re doing it bro!
You load up a dahm video, instant revving engines and turbo flutter, straight to business.
Lol that was cool seeing another perspective of Chris Foresburgs car, and seeing Larry Chen being a goofball
Always love it when Isaiah is back
Getting sideways with Forsberg, with the man the myth the legend LARRRRY!! in his supra. HELL YEAH!!!!
Car manufactures: The rotor engine is unreliable..
Rob: +sips his tea+ watch me change that...

Yeah the car journos like top gear and the rest are like that. It's..odd
waiting for the turbo to suck up a bit of the ceiling paint on the dyno
Hmm 1:30 when Isaiah says he’s almost done... then rob comes in saying he’s exhausted.... i think there is something they need to share
Wow I never thought I’d see the day rob actually drove one of his creations
The anti-lag off the throttle in forsbergs 4 door sounds insane, sounds like the group A Audi S1 Quattro
Fabrication father finally 💪🏾
Rob actually giving extra content opposed to stalling for 15 min is why he's a great youtuber
Should probably get a filter or cover over that turbine. 11:58-12:00 almost got spicy 😂😂

Love the car man. And I STILL watch the half mile record video from time to time
God damn this car sounds great. Nothing like a 3 rotor. Love seeing this car back alive!
3 rotors is the perfect amount of rotors a car should have. Sounds fantastic
Rob has a huge Bolt on/strap on turbo 🤣🤣🤣. Can't wait to see the upgrade.
Oh man.. between you and the vargas bros, your making me want a rotary. Awesome shit man!
Get one,you can pick up an RX8 for not much money.
I would go for a car from the warmer states if you're in America as the RX 8 is prone to rust on the wheel arches,sills and boot/trunk lid around the 3rd brake light.
