If only professional awesome racing could keep their products in stock long enough to buy them. Feels like every universal product is in perpetual backorder

I though Rob said something really powerful in this video. At around 16:39 he says "The guys are giving it their all. It's not enough time to be honest. They're new to managing a project because I'm finally just not doing it. They're realizing that they have to prioritize certain things." In the past he has talked about how hard he and the team is working and how little sleep he gets, but he always left finished the statement in a positive light. Whether the positivity was in the form of praising the work of his team or showing off some new top of the line part they are going to use, he always made it seem like they are doing just as good of a job as if they had more time. It seems to me though that they really aren't. The first case I really noticed was when they had to fill in the those massive gaps on the mounting rails for the smooth bottom. This seemed to be just a mistake from cutting quickly and trying to save time. The lack of time really came to a head thought when building up the engine. Rob was down to the wire on time and couldn't find the rest of the dowels for the third rotor, so he just put in the two that he had and ran with it. This significantly reduces the durability and power-making-potential of the engine. These actions show how the team is rushed on time and really is cutting corners to get it done. I think that it has been obvious to all that have been following the build that this has been the case, but up until now Rob hasn't said anything about it. Today, though, Rob actually said aloud that they are running low on time and the car could be done better. I thought that this was super brave as it breaks the character of "Rob Dahm". That character never really admits something could be done better until there is something new and exciting to replace it with. Until then he doesn't mention it or only has praise for it. The other part that I though was brave was admitting that the team could be better and also saying that Rob isn't doing it all. It's not exact what it means in this case, but it could mean all the work or managing on smaller items, not just setting the larger vison. Both of possibilities reflect well on Rob. They mean that he is delegating work to others and letting go of some control on his projects which on projects, like this one, that mean a lot is very hard to do and admirable. Completely unrelated, but also super cool was Isaiah talking about the struggles of going from the sole maker to being a manager of many other makes and how it is hard to communicate a good idea in your head to all the other people. He also talked about how when that communication breaks down the project doesn't get done the way that you were envisioning and that it feels like it would be easier to do it yourself.

i fucking love the team being on camera more especially isaiah with his beautiful honest talk

Wingmaker: how much down force do you want? Rob: yes. Wingmaker: but the dra... Rob: *DID I FUCKING STUTTER???*

I love the random ass order these videos are in lmao

The time, effort, and expense on this car is off of the charts. Rock on, Mr. Dahm and crew!

15:39 should said 200 pounds of Dahm force

Yes, you definitely need to open up some front wheel well reliefs. It's already preparing itself for the "Mercedes Flip"

that dude that put's his arm in front of the grinder while he is grinding in his direction realy has no fears

Sand down the aluminum on the font diffuser to make it seamless it is detaching the Flow. And also do this on the rear diffuser. Ticker is better remember that the surface area of the floor is higher than the wing and it is generating far more downforce than it.

Titanium sparks white because it burns extremely fast and extremely hot. As titanium breaks down into particulates it becomes more combustible with the right mix of oxygen and can burn up to 3300°C. I do titanium 3D printing and have to take a lot of preventative fire measures depending on what I’m doing with the stuff. We use it as a blasting media and it has caused a flash fire in our cabinets before. Alloy printing is a lot of fun!

When watching his videos the time goes by so fast. That car is looking amazing too.

Let’s go Rob! So excited to see you tear up Pikes Peak dude

@18:50 I’d recognize @motionautotv shop anywhere, where you at Trev!!

RAD!!!!! Truly an inspiration Rob!!! Make it up that mountain in 1 piece...Can't wait to see it.

This is the best thing I think I've ever watched, car-related. Between the madman and the fabricators watching his ideas and what goes into building a world-class Pikes Peak car, it's so awesome. I will say when it comes to my project cars, you really brought me down to earth, lol.

I think the front splitter down force explanation was awesome... simple but that was a good perspective of what is actually happening

It's mad to me that almost out of nowhere, the three rotor is suddenly your most serious race car. At least until the indy car gets running.

The hair at 15:15 shows real commitment!

Rob Dahm the way you improve cars is like an engineer would have done in his work area. You are straight forward, efficency, power, weight, grip and resistance, godly work🙌🏼🙏🏼🔥

Rob actually completed Pikes Peak in 11:04. He did it!

I love this build series. Fabby daddy is the best part of this channel.

11:04 as a rookie at the top! Rob you have overcome my expectations by a LOT! Incredible how fast you have become a legitimate racer with a hell of a car. Well done Rob! How exciting!

Babe wake up new Rob Dahm video just dropped

You know Rob's a genius when his handwriting is on point 20:45

Man, I am just SO invested in this build. I have dreamed about going up Pike's Peak since playing Gran Turismo 2 so I guess I'll just have to live vicariously through you. 😅

I'd love to see a collab of Rod and Mad Mike

Wish i could go to the hillclimb this year😢 got Aneurism surgery instead 😏

Love to hear isahia say "i have great ideas, just find it difficult to get the point across" we love a self worth king working on himself AND the team helping him ❤

The Venturi effect is so amazing! Creating vacuum from still unmoving air! Nice!

Loved this ep. Felt like I was in lounge bar with chilled piano music watching some art installation being created. Love the content 👌

1:10 unironically amazing explanation. I never knew this until now.

Putting the wing that far back is going to cause it to have a huge lever arm and produce a torque about rear wheel, lifting the entire front end up. Already the car will be rear bias since pikes peak is up hill. This car will understeer like a mac truck and make those ohlins worthless. Unless you can get such high front downforce you can balance the moment, then ballance the rear force. Drag on the wing will also contribute to the moment via mounting height albeit less so. If u leave the wing there i would trim it to absolute minimum. Don't trust me though just do the math.

can we get more Isaiah welding to relaxing music. It was surprisingly satisfying.

this is such an awesome build!!! Can't wait to see your run!!

If you need to mig a gap and the material is thin, use a copper plate/flat/ bar at the back to stop fall away.. it will help you get a smooth finish on one side and nice bead on the other, 5-6mm gap is the limit, smaller will work a treat. Also counter sink the screws (Aircraft skin style) so the road and curbs don’t shear off the heads compromising the plates adherence to the underside of the car.

Rob you wildin bruh😂 0:20

Very cool car and happy I got to see it in person. Hope you're having a good time in colorado springs!

Robs context is educating as hell and I love it

Saw this going up the peak it’s sick!

Friday just got 5 times better thx Rob!

Rob you’re doing amazing ! Keep it up brother

I watch several other KZfaqrs like the rest of us I’m sure. But this is the most exciting thing right now. Watching the FD come together and be the monster rob and the team have created is inspirational for sure. Love it

Can't wait for ore of this build! Carry on gentlemen.

Dahm is one hell of a Wingman

This content is absolutely come captivating I love watching this I love listening to this and geeking out over stuff I don't even know how to geek out over

I love this technical stuff. Nerds are the best!

Can't wait to see it at the halfway point. Making max down force for the win! I'll see you in 48 hours Rob!

The music and Isaiah welding...pure ASMR, could fall asleep to that stuff :)

At the 18.33 time marker, I see something wrong in the design. Since we're dealing with Aero Dynamics why not using flat head screws and a counter sync ??? Less friction and making it perfectly flat. I reeally enjoy your channel and wish you great succes

Can't wait for Sunday!!!! 😸

Man I love these stats and the progression of the RX-7

16:00 best music yet on the channel

Damn, now when I win the lottery I need two rx7s. One clean, one Rob Dahm Pikes Peak build

fav build series on youtube

Ya know at first I was thinking "ah why mess with the three rotor, just get it to the track but... yeah keep going this is so incredible.

Been watching since the Lambo. I always get a little giddy when I see a new video from you (guys). Keep it up!!

48 hours! Let's go Rob!

Honestly not sure how to say this.. but I've found myself all up on this channel for the passionate artwork of it all..

Feels like I got my surgery at the right time. Nothing like a almost race day crunch for the videos to come flooding lol

Epic project!

Now that is a wing.

Dam! Ow that’s a wing. Great music too. My kind of jam. Regards for Montreal.

FINALLY my daily dose of Rob Dahm adventures

Hearty effort there rob Try duct your front cooling straight into your radiator/ic then duct it out the bonnet instead of having vents,youl notice a significant reduction in front end lift

Absolute savage on the grinder 🤘

You guys should fabricate a flat bottom kit for all the rx7 enthusiasts out there 💅🏽

Also interesting when you see most time attack RX7's they have crazy square sideskirts lol. Also Rob after has to be 10 years maybe 11 I still absolutely love what you've been doing on this platform! Literally magic!

i love the chill jazz music. and the rest😄👍

Now that, looks like a proper race car!

With that front lifting I feel like it’s almost going to create that famous crash Mercedes had at the Nurburgring

Gotta weld those from the top as much as you can, go a little hotter than usual and once you get the puddle draw it down to the sheet metal until it connects, then right back to the thick parent metal(square tube). Had to do this often on through floor subframe connectors.

You need to do air jacks they would be best for your application

Here at pikes peak ready to watch you go up the mountain!

Nice throwback with the Motovicity shirt!

F1 uses a large rake when they setup their aero. Very efficient aero. as the rear compresses downforce increases. Any side skirt around the whells and side to keep air from getting in under the car and keep the low pressure area

PRO AWESOME ALL THE THINGS!!! Seriously though these guys are great!

LPT: Use countersunk screw for the flat bottom. If you car drags somewhere (Like a little oopsie offside track or just hitting a curb) the screw will be gone and it will make you lose time drilling it out in case you need to remove it.

We use chill bars when welding thin sheet. Piece of copper on the top side will make your life soooo much easier! Shoulda tigged them gaps;)

That mullet is giving crazy Danny McBride energy.

3/16"!!! That's rally car skid plate thickness!

Yay Rob!!!

Oh wow, planking, that brings me back 🤔

Aw man the music was so nice and jazzy and then it turned into full on random youtube stock tracks :D :O D:

Rob: We have no time to finish this racecar. Also Rob: so anyway, I did some math... This boi probably calculated the odds of him getting the record.

for the underbody panels look into ACM panels. (aluminum skinned hollow core) It's what lightweight aluminum trailer skins are made from. Send Cut Send will also cut and supply it to you (not sure in large enough pieces though...) For areas that are going to "hit", you should look into Tegris (laminated woven PP - Milliken material)

Counter sinking the screws on the flat floor would help reduce drag and use silicone or sika to fill in the holes or edges and sand it flat n smooth helps as well

16:32 this was hard to watch, if that thing slips...

Rob acting like Ryosuke Takahashi at the end

This car went from stun to kill great job one bad ass rx7

its going to be realy cool car

Next time, the front diffuser overlaps the plate behind it. That will prevent incoming air from catching the flat bottom and opening it up, which it will at speed. General rule, plates in front cover the edge of the plates behind.

Hey, Rob... You should talk to Keeps about a sponsorship deal where you grow your hair out long and they pay you X amount per inch per month. FYI, having had long hair and short hair, long hair is a lot less hassle. You just tie it back and go to work. No hair shmoo, no blow drier.

Upside to the thick flat bottom is you have major protection for the chassis and all the sensitive stuff in case of gravel spinouts and other accidents.

When you're not crunching time, you could take the thick aluminium panels, a router, a carbide router bit (flat bottom cutter) and cut triangle pockets, leaving only a thin metal between the reinforcements. That would lighten it up without losing too much structure, thus requiring more material for ribs. All you need is a plywood pattern with an oversized dorito hole for the router to pick up on and cut on a flat surface.

Yo, check out alumalite for your flat bottom. It's basically aluminum cardboard made with two thin sheets of aluminum with corrugation between the layers. It's super light and very stuff for that weight, plus pretty cheap for what it is. It's widely used for sign making, so in theory large sheets are easy to get from local sign shops. I've heard of lots of people using it for flat bottoms in the grassroots motorsports circles. Definitely worth checking out!

You can also add a small duckbill spoiler to the rear edge of the trunk lid(rear aero setup like the rear of a Daytona Prototype) that will drive the diffuser even harder than that high mount wing will and possibly(probably?) allow you to run even less rear wing angle for less drag for a given amount of total rear downforce. Definitely not 'necessary' of course, but it's also an easy addition in the future if you wanted, solid low hanging fruit for some aero optimization(assuming time attack rules allow for a rear wing and spoiler). Can't wait to see this thing running up the mountain!

Hear me out... electronic pressure gauge on the brake line close to the pedal > pressure gauge sends signal to an actuator > actuator opens or closes the angle of the wing based on brake pressure.

This car is going to be an absolute beast

Ran a 11 minute lap. In 95 two guys in Rx7's ran a 10:15 & 10:18 up the peak so he finished but wasn't that fast compared to 30 year's ago Rx7's. His is awesome but id like to see it more after fine tuning.
