[@andrewcastiglia9548]

I used it! Thanks for the groceries rob

[@eriklarson9137]

The code should be "12 rotor only".

[@rotorhead5826]

Hey Rob, if your engine is centered it can affect handling and load transfer negatively under acceleration/deceleration. Ask guys who ride BMW motorcycles that have flat twin engines.

[@akidafloof]

Rob, your car has 4 safety recalls, I don't think your warranty is gonna cover this

[@bhx7527]

would it be simpler to move the motor/trans farther right to clear your leg, like the old preludes? I know you've probably done more work by now, and this would require custom halfshafts but something I thought of.

[@joealex65]

"Move it 8 inches deeper". Rob Dahm - 2024. 😂😂😂

[@DaVe-iSnOtHoMe.MaN.LemmingsWeB]

Just think how many thousands of Hours are cut an hidden away forever

[@eriklarson9137]

It's all about the 12 rotor!

[@eliminster06]

so a while back I had the opportunity to talk to both Fred Veitch and David Donohue about what they preferred for going up pikes peak and they both said it takes a softer suspension than you would think. So while I think you are going about the right adjustments to the body I wouldn't focus on lowering the car as much as you think and would instead focus on allowing the tire to move more so the ripples in the pavement wont disrupt the cars balance.

[@wobblysauce]

Indeed, more travel gives you adjustment room. People go to low and hard often.

[@makhoe1]

[@jok3yjesu339]

I'm just saying I would recommend looking into a sfi rated bell housing or at least a blanket to go around that. I love it man but as I get older safety really matters

[@justjonazjameson5559]

I expected that you had to have one to race at Pikes Peak

[@larryboy8821]

​@@justjonazjameson5559yeah, I'm curious about that as well.

[@_Mav]

Pro-tip, when using an angle grinder use it to score along the metal until it goes through, instead of using it like a reciprocating saw. The blades last 50times longer. Can confirm, I work in car restoration.

[@oikkuoek]

When doing wheel wells: On a stationary driving wheel 1 1/8" side clearance and 2,5" radial clearance. On turning non-driving wheel, 1 5/8" side clearance and 1,5" radial clearance. On turning driving wheel, 2 1/4" side clearance and 2,5" radial clearance. Minimum. Measured from bump stops, lowest points and turning locks. Anything smaller will start to accumulate dirt, rubber, grime, rocks etc, "But Pike's Peak is on asphalt!" It is also a normal public road, with a periodical winter. There's all that and then some on that road. Also your tire is all over the place when you are pushing the rig. Even your tightest radial street tire with the "rim cover" profile will expand and move sideways when pushed. It needs room to live, otherwise it doesn't. Also, you don't want to get steered by your tire rubbing, while navigating through a narrow hillside trail.

[@aidansoliday7913]

Isaiah is an absolute legend and the luscious locks only make it better; keep ‘em growin

[@Kneedeepingore]

For future thick aluminiumwelding, always chamfer buttjoints (on the alternatorbracket). That joint most likely barely penetrated 1mm down.

Isaiah saying “married to the game” could totally go on a shirt above a shot of the car mid build

[@hyper8545]

Someday rob will do a single rotor motorcycle or something I can feel it

[@patrickm4566]

I’m not really a bike enthusiast, but I’d love to see a rotorcycle. Rob would be the ideal guy to do it.

[@Jzatloukal]

From my personal experiences I've always put power steering coolers in the return line from the rack to the reservoir since that line is much much lower pressure than the feed line. This allows for a greater selection of coolers and less risk of failure by having less connections in a high pressure line. Additionally cooling the fluid before it returns to the reservoir helps limit heat in the system.

[@blakefeurer2519]

My dream is to build a z3 time attack car with an m70b50 built with forged internals, dry sump, and twin compound turbo setups. You’re an absolute inspiration, Rob. I’m starting my own business this year so that I can make enough to get the space needed to start working on all of my projects and testing. I have more respect for you and your team than you will ever know.

[@michaelh.1262]

Z3s are badass. Goodluck sir

[@LtdJorge]

Damn, that’s a cool engine. Do you have estimates on the power it could produce modified like you said? I’m guessing probably too much for the German Miata to handle perfectly 😂

[@deltacharlieecho4732]

@@LtdJorge as far as I’m aware nobody has done it before. There are people that have built the m50 to over 1000hp so I’d say that 1200hp would be a reasonable starting point.

[@CoopaCoop]

1am video drop? Yes please!

[@paulhowlett6619]

Rob. I suggest you partnering with someone to release this subframe to the public. Even though yes it’s very specific to your needs. It would make 3 rotor swaps better than most methods by literally making it essentially a corvette. Hopefully after pikes the data and revisions will make it better

[@David_Conant]

You’d need to remove a lot of the floor to accommodate it.

[@ax75f92]

Love everything about this. Prob never see this comment, but you might find some inspiration from some of the Japanese time attack FDs for your rear diffuser. Specifically the cutting of the rear bumper up to the license plate to allow for more angle.

[@thepcguy007]

Your enthusiasm is contagious, Your fabricators are fantastic. I can't wait to see that car on a track.

[@gusrodriguez85]

The amount of work you guys were able to do in just 30 minutes was insane.Great job!

[@DavisJDaniel]

Hey Rob hope you see this i was talking to my dad about your competitiveness withe the mileage stats your insight gives you and he suggested taking off the passenger mirror like one of the old metro xfi (legally you only need 2 mirror is cali) also idk if you even have the insight anymore, im not the most loyal fan but just a lil idea. thank you for the content brother your a crazy man. keep at it.

[@simonname7530]

Can see how Mazda replicated the layout with the RX8 engine being further back compared with the RX7 and having the radiator angled.

[@robertutley9768]

rob, i just wanted to say, i absolutely love your videos. theyre so damn informational. and for someone like me, trying to get into the car building industry, your videos are an absolute godsend. you actually show us what you do and explain why you do it. i love it. keep up the awesome work man.

[@jes2731]

With all those separate lines all needing to compete for the same space around and through the serpentine belt in that one area. You have a CNC machine. Design a passage block that fits in the space provided, so that all lines in front of the S-belt can plug into, and then all the needed exit ports to the rear, top or sides can redirect to. The block would have all the needed passages drilled through with the appropriate AN fittings at both ends of the connecting passageways. Then it could even be incorporated into the bracket all the accessories are connected to.

[@Bob0sModelFabWorx]

I like to watch a lot of builders and see how each has their own style of building and modifying. One thing I like about your videos is how you explain WHY you made each modification. Sown to how it makes the car react. That is a major "awesome sauce" in my book. Thanks.

Great video Rob! I love your enthusiasm and drive to perfection!

Any day (or night) with a 3 rotor vid is a good one in my book. Its admittedly a bit painful to watch whenever you have to cut some of the original car away, but seeing you guys build it back up and build it better makes it all worth it. I can't wait to see it finished and out ripping again.

Thats some crazy custom design work, going to be awesome. Hey when fabbing with those cut off wheels in car, use one of those like 3M full face masks with breathers w/ peel off protectors. Look like your going into nuclear war but you can get sparks in the face and be fine, plus not breathing any of that bs and getting black boogies. Only like 50 bucks. Love using it for cage and chassis work.
