The AWD 4 Rotor Breaks the Rotary Half Mile Record! 

no, i wanted a 40 minute video 🥲

Leet

:D

13:37 minute long video on a 1337hp car, now that's leet!

Came to say the same thing. Especially after his last 1337 comment :)

Omg good point!

I wanna point this out but you already says that and ground effect is really sketchy….even current F1 aero struggle with that last year 😂

​@@RobDahm thought the same thing, the car kicks dust like a current generation f1 cars But something isn't quite right but I'm sure you will figure it out

Wind tunnel is the only answer at this point I think. (at least once all the body/aero is on the car as it's final form is going to be... This iteration's at least anyway 😜)

My non-engineered youtube science says most of the dust kick-up is just the rear diffuser. Doing exactly what it should; what is missing is the rest of the ground aero. WIth how important aerodynamics are, this should be the focus for Rob. Making sure all those holes inside get covered so the air is going over and under. Right now I imagine the inside is just causing so much drag. Wheels need more aero to remove dirty air as well. With a focus on aero and then tuning the car, it would be easier to deal with. Tuning a car now seems like learning how to tune a parachute full of air. ~I made this comment before the ending of the vid where Rob even mentions aero. Love all your videos Rob, been watching very early on. Happy you are sharing this journey with the rest of us.

🤣🤣

Someday. Not today 😂

I’m glad I’m not the only one that Mis read the title lol

@@RobDahm God, I hope not

2wd 2 rotor lol

When TRC showing love, you definitely did something right🔥

It definitely wasn't dufuq...u watching the same video?!

I bet it breaks after 10 runs... all cars like this are junk... just people trying to be "fast" I bet a stock tesla plaid would beat that pos and never break that running 10 times is guaranteed to break

​@@S2KCYA xdddd

​@@S2KCYAlol you must be new here 😂😅😂😅

4 bars, that's some serious diese engine boost

Where's the next video?

And that ferrari is sf90 i think which is very very fast

@@rishabhbhatt1393 It is, which is the fastest Ferrari ever made.

Not only that, but Rob said that he only was in the high 20s psi range for boost and it can go up into the 40's... the thing is gonna be a Dorito missel.

That AWD burnout was crazy

NO SHIT! Put some tires on the damn thing! Spinning tires, loud revs... doesnt really do anything! If its going to be a drag car.. or at least try.. gotta do it right!

agreed

Yup. At this point, the things that keep the car from performing aren't the running body, rather the body itself.

agreed

@shrerd1894; clearly You lack the proper basics about electrical, digital signals, wiring, etc. A. The variations, spikes with the digital speed sensor are clearly clean, stable until much higher speeds -> thus clearly NOT an issue with any interference ! B. Thus, clearly, obviously, certain the issue is intermittent connection at higher speeds, RPM 1. The first area to check are the connections, connectors from the wires of the sensor(s), which are vulnerable to the vibrations, due to higher RPM and wind speeds,. 2. The next is to verify the wires inside the sensor and sensor itself - this should have shown up with proper high speed testing on the dynometer, but perhaps they did not operate the vehicle at these higher RPM speeds 3. Also the actual higher speed driving, especially on this aircraft runway, has additional variations, vibrations, along with the high speed air flow during very high speed travel as this 4. For these reasons, basis, poper planning, connectors, connections, wiring, sensors must be proper, carefully selected, chosen, wired, installed as those within aircraft, high speed vehicles as F1, Indy, NASCAR, NHRA/IHRA/PDRA, others 5. typical "Trial & Error" process among the amateurs, novice, platform-video producers, including many which modify, build performance level vehicles, many for drag, track, other racing but not trained properly,lack the proper knowledge, especially within safety are extremely common and should be clear, obvious to humans with proper basic thinking as examples of "what NOT to do"-"NOT follow", don't do as they do with their mistakes, errors, claims etc. All The Best

Absolutely. The dynamic between them is so relaxed. True friendship is immeasurable in value and a beautiful thing to watch.

So true, I remember how he talked in a negative Light about the rotary car in his first video. Most rotary owners go through this and also went through it also and now I am a rotard. A rotard is someone who does not give up on the rotary motor but instead educates himself on how to properly care for it. Rob is a rotard and making great videos for us other rotards. Brap on

You're so fuckin right

I think you hit the head of the nail there It is very very VERY probably that's the reason of it

No doubt. Had a sway bar beat the new bushings out on a turbo vehicle I own and top speed it would rock side to side. To the point it seemed one minor movement of the steering wheel the car would lose control.

Except for the fact this doesn't have a normal suspension.

@@x808drifter Still need anti-roll bars of some sort. The mechanics of the instability don't change, just the motion ratios on the suspension components themselves. Without something to suppress the roll, it'll just continue oscillating and only worsen as speed rises.

most rotors shot into orbit after hitting 60psi boost

Fastest rotary is like being the smartest retard.

I was also wondering if having the rear window in would help.

Even ??!! This is the clear, obvious indicator of the sensor data issues - clearly a wiring, connector issue at speed, possibly inside or the sensor itself. High speed, especially vibrations, perhaps wind speed are affecting the electrical connection(s) of the sensor, thus electrical voltage outputs,, with such intermittent, quickly varying voltage values, thus reading. Basic knowledge about electrical wiring, voltage, digital signals are helpful to assess, evaluate, troubleshoot, diagnose, determine, and actually initially proper wiring, connections, connectors for this application, use are essential, but clearly lacking, as usuasl with Rob Dahm within his 'Trial and Error" process, ignorance = Failure All The Best, Sincerely

Yep, looks electrical to me. That input is noisy af

@@jnevercast the description of 'noisy' is nearly close, but still inaccurate As in my comment, what is clearly seen in the shown speed sensor data at the higher speeds is certainly quick, variation spikes in both voltage directions, thus certainly due to intermittent electrical connection, not noise which is interference. Basics knowledge and experience within variable DC voltage lines, signals, as from these sensors result in proper, correct assessment, evaluation, differentiation, discernment, troubleshooting, determination, conclusion, solutions The specific process is detailed in my previous comment. All The Best, Sincerely

The lack of rear window is a bigger issue...

Clearly You lack the obvious, clear issue with intermittent, quickly varying voltage as seen in the ECU data and on the speedometer !! The issue is clearly NOT limits with the speed sensor, else it would have reached its upper voltage limit and either remained [as would be expected] or alternatively with a poor design dropped to zero !! Another individual with simple lacking of the basics with electricity, electrical voltage, sensor outputs, ECU data. Goo Luck, All The Best, Sincerely

@@newtonfirefly3584 Perhaps instead of being condescending, try being constructive. And instead of putting people down try engaging in a discussion. If we apply some logic to the situation it is apparent that all 4 wheel speed sensors are reading all over the place. That tells me it is unlikely to be a single sensor that is bad and even less likely for it to be a wiring issue such as chaffed wires. Now as far as my understanding goes the wheel speed sensors are putting out pulses which are read by the ECU. Those pulses could be coming fast enough that capacitance in the wiring attenuates the pulses enough that the ECU has trouble accurately reading them. Or it could be that the sensors are not capable of reading a trigger wheel going that fast. Seeing as I do not have the model number of the wheel speed sensors, and I don't have the time to look for it in the videos, I will elect to just speculate.

@@ryanhebron4287 Ryan Hebron, clearly You have trouble differentiating between criticism, conveying proper information and condescending. My comments are directed to those like You to be aware of the nonsense Rob Dahm presents, does and proceeds with including the disregard for his own safety, life and those around him that he affects along with those that are easily influenced. Already have attempted many comments directed specifically to Rob Dahm, including with specific suggestions as contacting FuelTech, Anderson Dick, Luis and their dedicated rotary expert, but he continues to proceed within his mindset, arrogance, etc., refusing to make any effort. In addition, Your ideas about what You describe as "pulses" clearly indicates Your basic lacking with electrical voltages, voltage variations, voltage sensor outputs along with the clear indications, comparison which Rob shows in this video and at least comprehends somewhat about the possible issues, which You clearly have no idea, concept or clue, but Your self-proclaimed imagined, contrived nonsense. If You will ever gain the basics about electricity, electrical voltages, as the simple DC variations from sensor outputs, then You may begin to possibly comprehend the possible, simple causes as inn my descriptions. My basic knowledge form my first basic electricity course within 8th Grade IE, 50 years ago, is enough to comprehend, assess, evaluate, differentiate, discern, thus troubleshoot, determine the cause of the clearly noticeable problem. Certainly my further development is just more extensive into proper design, development, etc. Your idea clearly indicates Your lacking with basic information about the sensors, voltage outputs, standards, etc. Good Luck within Your ignorance. All The Best, if You choose to improve, grow, learn, develop. Sincerely

Clearly KC, You know nothing about "Theory", proper principles, ideas, concepts, though You did clearly properly figure the issue is with speed, though clearly lack the proper basics with aerodynamics, electrical and the effects of the variations, varying speed sensor voltage to the ECU which affects the vehicle operation including driving stability, as Rob directly stated [at least he knows it does affect this, since he arranged the ECU to use this information within its controls] Good Luck, All The Best, Sincerely
