"The math it mathing, because it's brapping". Get that on a t-shirt!
When the math is mathin', the brapp is brappin'.
100%
Put it on your own t shirt
t shirt please!
That's what I'm saying...
Every thing rob does is “It’s just so crazy it might work”. Dude has drive and it’s amazing to watch him work
You are so right it hurts. Wildly enough i just did Pikes Peak testing and it was the first time i had driven the car over 10 mph. It made several back to back runs and is still ready for more. we melted tons of things but the drivetrain is solid haha
@@RobDahm Hell yeah dude!
@@RobDahmdon't spoil it for us rob. Let us watch your Journey. Now i already know it doesn't fail. I want to feel that fear that comes with it when you do the first runs.
Darn i can't like this comment. It's at 69 likes...
There are some insane twists in the story i promise not to spoil how the journey goes further
You can dip an electric water heater in the sump tank to preheat the oil. Many race teams have something like that so they can preheat the car in the pits. Oil on temp, engine and coolant will warm up in one or two minutes once the engine is started.
Mmmm VR1 sous-vide
Doesn't dip in the oil it's a tank heater it's either got a element inside the tank that gets plugged in to heat up or you get a oil tank blanket by moroso or all start
@jasongariss5858 It would not surprise me at all if there are low budget race teams that do actually dip submersible water heaters in their oil tanks to heat them.
You can get others that run external heaters with push loc fittings and a pump.
Rip a kettle apart and drop the heating element in
Oh wait Americans don't do kettles do they
You get that drip pot coffee
im 19 and seeing shit like this inspires me to go learn everything i can about swapping engines and do this myself. you're truly a legend rob and I cant wait to see the finished product and what you'll do next
Just do it, spend down time researching but .... Just go wrench.
19 years old and your just getting the inspiration? Your about 15 years late. Got lot of catching up to do
@@acurarl9929 I’ve been working on small engines since I was 7. The only reason why I’m getting into it now is because I grew up in a very poor household and I finally have the funds to be able to pursue what I want and not a career path already set up for me that I won’t enjoy at all
Do it. Do all off it. I'm almost 40 now and I regret not getting into all of this stuff when I was younger. For all the negative of the Internet and smartphones, it could have made me a beast as a young guy with all the knowledge available with smartphones and YT today. I'm addicted to learning new skills and learning about any and everything. Go balls deep in that field because skill jobs like that are the high paying jobs starting now and in the future. You don't need to go in crazy debt either by getting a BS degree in university colleges. Also AI will replace most media and arts and a lot of the suit and tie careers.
I'm 21 now, I K swapped my mr2 when I was 18, didnt know anything when i started built the engine myself and it made 500whp on the dyno. learned exclusively on youtube did everything myself including fab work. car is now at about 650whp with a K24 setup. Building that car has taught me an unbelievable amount of stuff and I wouldn't be where I am today if I hadn't. Go for it.
Sleepless nights incoming lol
It’s the gearhead way
Incoming? They’ve been happening for months at this point…
I don’t think they know what sleep even is 🤣
If this dosent show that rob is just like so many of us out there while being so far ahead of us just look at his engine stand. He uses a random bolt for the locking pin just like I know you do too. lol or at least I know I do. Amazing as always rob good luck brother.
Mine has a pin with 2 springs that you pull up with a T handle. I built it myself to get rid of the random bolt I never could find lol
"billet" was Daddy Dahm left with that engine alone at any time in the night? Asking for a friend.
So much work! The time, effort, and expense is mind boggling. That is why I am a mere spectator. Rock on, Mr. Dahm! Loving each video. Every one of you should be so proud of yourselves.
Everyone needs to give a shout out to the guys at pykes peak for finding space to squeeze rob in a later date instead of missing his preallocated time. They could have just said too bad.
I do love that Isaiah has been letting his soul glow recently.
I fear for the wall behind the couches 😂
Someone get this man a paper towel for his colar!
Gotta see a parody of the original “commercial” with them spritzing on the VR-1 hahaha
He's starting to get that Ron Jeremy vibe. lol
@@dankolicious10 did Ron Jeremy have Jehri curls or was he just always sweaty and gross? Discuss.
The only man on youtube I can watch 40 minutes straight. Thanks for another video Rob!
thanks for the sneak peak Rob! Stoked for Pikes Peak!
Don't even need to watch it, giving this a thumbs up right away! Let's goo!
you gotta watch is some for the algorithm to count it though
@@paweszczepanski6738 oh I watched it, just had to comment first lol.
That Brap is music to my ears!!
Crazy scientist Rob is my favourite Rob. Can tell he's at 110% here!
The dyno tune on this thing is gonna be a fun future episode. It’s gonna be rowdy!
Magnum P.I Is going up Pikes Peak! Can't wait :D
Bearded Rob is like Rob's cool uncle. Whole different guy
Man this channel. Everytime you think he won't get any crazier with his parts, he does something new
Rob and the Kiwis are holding up the rotary flag and advancing the technology. And we are able to witness history being made. What a time to be alive! 😎🤘
So I have built a few dry sump systems in my time and have one question: With that oil tank sitting that high, and not using trochoid pumps, how are you going to combat oil backrun into the engine after shut off?
Otherwise, thanks for sharing this great build :-)
Good question. I had that happen on the 4 rotor when we fired it up on the engine stand years ago. The oil leaked back into the pan and out the turbo drain line emptying the entire tank over night. Right now it takes a little to start the engine with cold plugs so thats helping sort the standing oil but it hasnt been an issue yet. I know the cosworth team had the same issue. they would purposely not start the engine until the pan was cleared of solid oil as the hex input on the pump isnt strong enough for that load. crazy
@@RobDahm I recon that hot Valvolinel will be back in the engine in about an hour. Think two electrically activated check valves could help, or an electric oil pump just to scavange the engine before start.
This has been one of my favorite builds to watch ever, I can’t wait to finally see this tear up pikes peak. Good job Rob
And this is just the test subject for the final 4rotor. That's going to blow everyones mind if he continues this steady improvement trajectory. I badly want to see this one run pikes and hear it scream first, but i can't wait for those 4rotor videos.
Stroke of genius with the dry sump Rob, starting to look a sweet treat.
Rob Dahm is proof of " where there is a will there is a way" lol proved the flaco guy he can everything he can and then some Love the content following 10 yrs plus and the journey Is spectacular
38:58 your editor creates such an engaging video to watch. I’m so impressed by all of Thicc Boy Racing
Watching you take apart rotary and put it back together, I feel so comfortable now,I used to kringe at first
Same haha
So stoked for the build videos for the upcoming Pike Peak event, it's wild what you guys have accomplished these past few weeks!
Going to be so sick watching this thing brapping up the mountain!
For heating up your parts, those small torches dont put out a lot of BTU's, an oven would work better but the best option is either a oxy acetylene torch. Also a mini fridge doesn't really get cold enough to make a big difference, cooling parts doesn't make a huge difference compared to heating. Love the content man keep it up!!
The offset gives you an eccentric flow which helps reduce air and cavitation.
Been loving every video the entire time I’ve been following the channel, plus meeting you and Isaiah at SEMA has made me a forever fan. I love the videos, please keep making them and I’ll be super excited for whatever is next brother!
During engine assembly, do a whiteboard checklist. Right, very easy for me to say sitting on my chair at work here lol.
what I love about the man is he has to know and shares , not sure what happen to the old guy out here in Washington state in the 1990's he was running a 7 second drag car rotary he had a shop in place called mile hill in Puyallup wa , he was like the doctor around here when it came to rotary stuff , glad someone hasn't gave up them making them better ,
I still remember the day I first saw your video of the black 3 rotor at your house and going over it. Was such a bad ass video I showed everyone lol crazy to see how far you’ve came.
Rob, get some liquid nitrogen and freeze that bearing. It should fall in.
Good idea!!
Dry ice works on dirt bike bearings
And get a standard kitchen oven to heat up the other parts. It will be more controlled, and more evenly heated.
yes
liquid nitrogen is the choice
Sometimes dry ice is enough
That is a nice piece of gear from the bottom of the earth by the looks 👌
am i the only one that now wants to see more of rob with a mustache?!😂
Yes
Stash is hot
One thing that I’ve done in the field to heat up giant bearings on huge CNC machine spindles is to build a oven out of plywood and use the heat guns pointed into the box to heat up the whole part evenly.
Build up the metal by spraying it on with the spray transfer methods......you can spray on high strength alloys that stand up to wear....i used that method to give a big electric motor arbor a coating and it actually helped with vibration as well
Demasiado tiempo esperando qur subieras video Rob!! Este proyecto es de lo mejor que hay en CZcams... Full full race 3 rotors big turbo=best in the World
Interesting build. Congradulations! It's a BRAP!BRAP!BRAP! BOY!
Maaan I was like, Yooo what the heck. I'm gonna have to be in CAD all day with no CZcams videos :((((((((((
Good work dropping the video hen you did Rob!
This video is intense! You can really feel the pressure.
Rob doesnt know this but hes related to me far far far in the past. Glad you are doing well brother, Love seeing your passion for the rotary, Something about engineering designs makes our kin ecstatic and so passionate about what is.
that's a pretty weird thing to say
Meanwhile it took me almost two week just to restore a 2 stroke exhaust... You have way to much motivation for a single person, props to you !
I love the sounds those metal parts make when everything falls into place. Very satisfying !
For the heating for the interference fit, I'd recommend a portable electric stove, induction heating spreads it more evenly and has more control. May or may not work, but if it does it'll work really well
Serious quality race car stuff. Absolutely love it!
Not a race car application but my dad’s zero turn was having hydrostat overheating issues and the oil would foam and he’d have to wait for it to cool down. Switched to vr1 and haven’t had an issue since. All I will run in anything I beat on.
Yall putting all the love in it i was trying figure out how yall would assemble the fitting inside it whenbi spotted that amazing fab work im wanting to do the same with my transmission lines but dont have yalls knowledge of tubbing and fittings thats for shure
I started laughing when you pulled out the oil tank. I was oh yeah i remember mine. sat right behind the passenger seat, attached to the rollcage. Just ran the lines right under the passenger seat out the fire wall. good times.
The Mad scientist mustache look is back!! Hell yeah ❤️💪
thanks for the video, glas you where able to move it up
I hope you get some rest too before the race. wishing you all the luck
I used the same oil years ago on a eclipse gsx I built and after 2 years of 35 lbs and beating on it I took engine out to inspect and EVERYTHING was so clean and bearings had very lil wear…. Im a believer!!
Who knew a dry sump tank could be sexy? And with the VR1 being non-foaming it seems like a match made in heaven.
Rob is the coolest car guy on CZcams and it’s not even close. How can you not be cool with that flowing hair and more rotors than sense? Keep up the good work, I cant wait to see this thing shred on the mountain!
Did anyone hear Tavarish shout out Rob this week? 😂Everything about this build seems legit! Good luck at Pikes Peak. Just over 1 week to go.
I have been watching you and your crew evolve for years now and I can’t wait to see you guys on the mountain! I wish you the best of luck! Cheers!!
Insane amount of work the team put in! So sick!
i like to use a dry ice and acetone bath to chill parts for shrink fits...often it's so cold that you don't have to heat the other part.
Rob you may even consider safety wiring that regulator on, I don't know how high of a temperature loctite can handle, but I know heat usually loosens it up. With safety wire you wouldn't have to worry about it.
Bréthurr, This information is infinitely more digestable when you're chill like this,Thank you.
So ready to see this thing going up pikes peak. Your drive to develop a better faster more efficient car and your innovative attitude are unmatched.
Can't wait to see the results. Cheering for you.
the mustache goes hard
I was gonna comment this 🤌🏻
Gonna be great! Ever gonna have them fix your profile on the PPHC site that says your from Ontario, Canada not Ontario, Cali?
14:00 With my 20b, I always just used a block of wood on the plate with a prybar underneath the front rotor lobe. Quick wack on the front bolt and it separates with ease.
Atp the 3 rotor is more advanced than the 4 rotor, and it deserves that love 😂
Imagine if he goes crazy on the 4 rotor
@@justincharles6585 we’ve only seen a fraction of Robs power 🤣
It is pretty crazy to see how far the 3 rotor has come since the project car challenge. It is a completely different car now.
Omg, always a cliffhanger! Can’t wait for the next one!
Been watching him for years and it’s always the same feeling watching each video.
Old Skool Bearing Prep:
1) For Roller Bearings, a slight clean up on leading edge + Engin Oil film, reduces scuff when pressing.
2) Babbitt Bearings, a slight Cross Hatch on shaft surface with 600 wet - dry w/solvent, helps retain Lube Oil at HIGH RPMs.
Those were instructions from Buddy Morrison in 1971, B4 Reher - Morrison - Shepherd were 4 time NHRA World Champions 1980s.
❤
Just gotta say, your enthusiasm is infectious. Keeps me on track with my projects. Heres to great numbers at the peak!!!
Exciting watching this all come together!
moustache rob is best rob
Let’s go! Mountain is calling 🏔️ 🏁
I'm genuinely concerned about Rob racing Pikes Peak in an untested car. I have total confidence in his team, but we all know that even the best built cars need testing. Any thoughts, anyone?
Rob, Small champfer on that pre frozen bearing front edge would have been an advantage? Big TV screen on wall easily seen, HDMI to computer with pre-programmed each required step build sequence so dont forget anything e.g."dowels" bolt torques, hints, etc. Might make these last minute builds a lot easier to get right every time..... Great job anyway, look forward to the Pikes Peak run!
W for sure Rob. Thick Boy Racing has a ring to it.
The mustache is on the face, Rob is serious 😅 Goodluck, and all the best from Finland
Please brother: BE CAREFULL at Pikes Peak. I really want to see more of Your amazing content!
You should get a bottle of liquid co2 with a siphon tube for freezing bearings. Its relatively cheap and it get the temp down to -40
i am really starting to love rotary more than ever
looking forward to seeing you and the 3 rotor at pikes peak next weekend!
21:59 Have you considered integrating some form of heat plate into your hydraulic press? The top portion could be supplemented with a liquid nitrogen reservoir if needed, and the base could be heated many ways, but my initial thought was just using the elements from a hotplate . . . the goal would be to avoid both parts getting closer to a neutral temp when transferring to the hydraulic press
if ya get a cheap oven on market place you can get that aluminum at the perfect temp for the bearing to fall in. bake at 275 on the middle rack for 45 min.
Hope you break the record bro actually pushing the art
25:45 Rob, I am a mechanical engineer, and my job is to ensure medical devices assemble correctly-amongst other things. I would love to provide guidance on GD&T and material modifiers, so that you know parts always fit together-size is only part of the equation.
I try telling my gf the same thing. size isnt the only part of the equation haha. jokes aside i definitely have alot to learn about that field!!
Lets goooo!!! Congrats bro!! Well deserved after so much hard work.
Amazing Rob, I can't wait to see this rip up the mountain!
the thumbnail really shows just how small those rotaries are, its pretty amazing how such a tiny engine can handle as much power as they do.
RPM!
@@Anon.Gdoritos!
You know the math is mathin', son!
Excited for the dyno and the run(s) up the mountain.
Also, definitely get a lathe. It's time.
Awesome work. Hope it all comes together for the next test session.
You can see the passion in rob with this build.
Brand new Billet engine 48 hours before the climb? Damn bro. Balsy! 😅
24:09 I haven’t seen those 3 leg stools in ages!
Who need sek when you got Rob building a Rot !
This is so beautiful !
I miss my Brap Brap RX-7 baby, I need to bring here to South Carolina. That's the best sound of the rotary.
So excited this is getting so close I can't wait!!
You and the boys are killing it Rob.
