I really love how many Aussie brands Rob is using in his builds, from Haltech and Xclutch to Turbosmart and Speedflow. Really makes me feel patriotic ♥
thx rob for the continous rotary content. you opened my eyes to the art of rotaries and now I own a project rotary car that I rebuilt and it's up and running!
Bs, if that was true you'd have posted about it along with your not copyrighted music vids. And before you try and give some snarky response to not posting any pics or vids of it... You posted meh copyright free songs on your page with meh animation but nothing... Literally nothing about a "project rotary car that you rebuild and is up and running". Really? gtfoh mate.
The 3 Rotor reminds me of Legacy code. You start with one thing, then another, then eventually you've redesigned the system from the ground up because "well everything is already shit, can't get worse"
Thank you Rob for giving me the time of day and having a whole conversation with me at Gridlife Midwest, won’t ever forget that P.s. you’re taller on camera 😂😂
Every time we see the 3 rotor, it just gets better and better. I love it. I've said countless times how much I love this car, but I don't think it can be understated. I'm glad you've still got love for it even after all this time and all your other projects.
Hey Rob, have you looked into turbo's that use their own lubricant? Im currently running Comp oil-less turbos on both of my rotary cars and while they aren't oil-less they don't use the same oil as the engine. However because you dont have to worry about gravity returns you can mount these turbo's in any orientation, great for tight engines bays. Ive had alot of success and fun with them since switching to them in 2019. Just a few squeezes of their mineral lubricant every few 1000 miles and your good to go. And the spool up compared to the Precision Gen2's they replaced is amazing. I know your a Garrett man but I was just wondering if you had ever checked out these kinds of turbo's. Keep up the great work fellas, DORITOS 4 LIFE!!!!!🤙
@@matthewsoules7064 They indeed are great for turboing N/A cars because as I said you don't need to worry about return lines so you don't have to worry about drilling and welding your factory oil pan.
100% agree about the love for turbos vs the love of cars. Both are a passion but something about a snail building boost and the sounds that come with it..
Rob I hope you know that you truly inspire so many people with what you do. Not only that but you take it to the next level and pour yourself into this work, constantly bettering yourself and widening your knowledge and skill sets. You are a prime example of a superb human being that I respect and admire. I hope that I can follow in the footsteps of the great men I’ve learned from in my life, whether that was in person or from a RUclips video. Thank you
Hey Rob, I'm not sure if this has been mentioned before, but if you guys were worried about airflow into the radiator with the front mount intercooler, would it be beneficial to run a V-mount style system since you plan to track this car so you guys can build optimal duckting to get more hot air out of the bay?
@lanezurowski6616 Ahh, I'm not 100% sure? But with how good Rob is with Cad and how good fab daddy does his work, I'm sure they'd be able to build something up since i think the front end on the 3 rotor rx7 is tubed?
@@lanezurowski6616 Its definitely possible. The Super GReddy 7 by RE-Amemiya springs immediately to mind. I do think its dependent on how exactly the engine and turbo are mounted as to whether or not you'd have space, though. The angle of the V could also play a part too.
Dammit Rob! I'm not going to lie as soon as you said you were going to weld it I thought "OH NO!" But you killed it Rob, nice looking welds homeboy! Let's go!
34:28 Rob pls pls pls be careful spinning wheels by hand with your fingers inside the spokes. Your fingers can get caught between the caliper and the spokes of the wheel. There may be enough space with this setup where it wont get wedged but the momentum of the wheel spinning can do serious damage if your phalanges get stuck
in computer geek terms since we have rads on pcs now with fans some even on both sides doing push pull configure, we like to call that term STATIC Pressure, being able to push air thru the restricted rad fins, with enough efficiency to drop the temperature of whatever is flowing threw the rad.
rob have you ever thought of running the coolers off a scavenge pump to not have to worry about pressure loss? i currently have this setup on my s2000 and it works flawlessly
You could build some ducting from the end tanks that routes air in between the oil coolers and intercooler for brake cooling. Just something i thought of.
I know you probably dont have the ability to make the angle of that intercooler hood less steep but i believe that with such a steep angle you're going to have flow separation issues. You might make up for it by pressurizing the incoming air as it builds up trying to get through the intercooler but i would not be surprised to see a pressure differential.
this is something I learned always replace your oil feed line when you replace the turbo especially on an older vehicle they get restricted or closed off after awhile from the heat cooking up the oil
Borgwarner predicted that style turbo over a decade ago. Its the reason many rotarys run them..larger exhaust wheels suit ethanol better too. That turbo will be more efficiant at higher power-not "less laggy"
Robert, there are three points where the front suspension system needs to be in alignment with each other. In the event that the car has upper and lower control arms, the pivots of the rack and pinion steering knuckles must be in line with the bolts that are slid into them. What will happen in the event they aren't? Bump steer. How does that happen? In a different way of typing this, how does bump steer occur? Look at the pivots of those control arms. Next, look at the wrong length of the rods that are attached to the ends of the rack. Do you see it? It's difficult to see it in your mind when you're not able to concentrate. That's what you need to do. No, I'm not angry at you while I was typing that. The pivots of the tie rods and the two control arms, when they aren't in alignment with each other, there'll be bump steer. In the event that the tie rods are longer that where the two control arms pivot, whenever the tire travels over a bump, they'll pivot outwards. The opposite is true when those tie rods are shorter than where those control arm pivots are. They'll pivot the two tire inwards. Why is it that way? That's a question you need to answer for yourself. The reason for this is because I'm not able capable of doing that at this moment of time. I'll possibly be able to in the future, except not currently, though. It's a possibility that I'll be able to answer this question relatively soon, possibly this night. Is it a possibility that I did answer that question? That's additionally a possibility. Why is it that way is the question. I believe I have the answer to it. It's because the tie rod pivots and the control arm pivots are of two different lengths. That's the reason why the three of those pivots need to be in alignment with each other.
Rob can you get a Piston or sparkplug cam snaked into your mask so we can see what you see while you are welding? It be a different angle and we can really see how those masks diffuse or lessen the light from the welder.
Hey Rob, can you link up the video where you talk about the turbo speed sensor and the setup your using? I don't need to do it on my current build but I'm nearing the end of the motor work on this one and might start my search for the engine for my z3/z4 build plan and start building it. I'm going to need sensors for EVERYTHING on my next build. Shooting to make 1k+ on a 5.0 V12 with dual twin scroll turbos.
Ido not know anything about rotary but it seems a drift car thing to rear mount the radiator I get the "street car" but you said race car Dahm so better weight distribution rear mount rad behind the rear axle seems the way to push this car as far as it can go
Im sorry but that tow hook is gonna snap off if they try to tow it. The tow hook was never made to be placed like that, and with it being a few inches tall and no support besides the nut it scres into, there is a bunch of leverage on the shaft and it will snap. Also even if it can pull the car by u guys if lets say u dont pull all the slack out of the tow line and all of a sudden it get taught all that dynamic force will cause it to snap off and shoot forwards. Also i think its in the rules for gridlife that there muchs be a toe hook front and rear always present or immediately accessible so i dont know if that would pass tech.

What has this man done
Rob you inspired me to get my first rotary powered car. Just picked up an 81 fb rx-7, thanks for making mazing content.
Awesome bro! Ive got a 83 rx7
25:58 "Now it's like an 8 footer" -Joel... such a backhanded compliment 😂😂😂 I friggin love it
What I would give to be chillin on my porch smoking or drinking and hearing Rob test his 3 and 4 rotor off in the distance. A true symphony!
The 3 Rotor reminds me of Legacy code. You start with one thing, then another, then eventually you've redesigned the system from the ground up because "well everything is already shit, can't get worse"
Like a big bowl of yummy spaghetti code
your the best car youtuber in my opinion keep it up
Rob having a centred steering wheel in this car is amazing after so long 😂
Man, a Dahm video w him talking turbos just hits the spot.
Adding tunnels to the front diffuser/splitter, very nice. Free downforce, ultra low drag.
The sound of the pulls, never gets old!
Rob your videos are always slightly massively better.
Words are matter times the sum.
Thank you Rob for giving me the time of day and having a whole conversation with me at Gridlife Midwest, won’t ever forget that P.s. you’re taller on camera 😂😂

It's crazy seeing how much suspension effects the cars personality.

Been having to watch LZs rotory stuff. Eh. Im glad rob uploaded. Ive been waiting.
Seriously though Me and my wife love watching you. I get my Rotary addiction satiated, and she gets to see all your cats it's the best of both worlds

Robert, to me, the engine sounds better and well balanced. It additionally seems smoother than ever before.

Amazing engineering at its finest!

Would a V-mount be possible with the 3 rotor or is it too long? I’ve just only seen it done on a 2 rotor but I imagine it is possible

Yay, thanks for another great update Rob. Cheers mate.
Rob’s t-shirts are cracking me up. Goonies, Ghost Busters… He’s an 80’s kid! 😂
I love that impact riveter got mine on the cornwell truck, it’s soooo nice for steel rivets
FINALLY! Another video.
Is the oil coolant hose anchored down to prevent chafing?
I know you probably dont have the ability to make the angle of that intercooler hood less steep but i believe that with such a steep angle you're going to have flow separation issues.

I love the sound of 3 rotars 👌 nicer than 4 for a street car 😎
Good to see Fab Daddy back in action!
Love your work Rob. You guys look and sound frazzled, hope the workload backs off soon
Rob. Love the Exhaust Sound very sweet info on Turbos too! Thanks
What do you think about twin turbo ? Or is that for the 6 rotary
Hells yea another Dahm Video!
@ 30:00 I can see how tired you are. We love you Rob. Take care of yourself ❤
this is something I learned always replace your oil feed line when you replace the turbo especially on an older vehicle they get restricted or closed off after awhile from the heat cooking up the oil
