Hey rob i work for a carbon fiber weaving company if you need need raw carbon fiber they sell nationwide and we can do any patteren and even program a rotor shape into the weave
Kinda doubt this ever happening sadly. Formula Mazda parts are spec and pretty cheap to replace vs a one off carbon piece. They are one of the get into racing types of cars. IE cheap.
Ooofff… you need a set of transport wheels and a tire rack for the trailer to keep the tires off the ground. That’s the setup most formula cars use to transport, at least that’s what we used when I was involved in F2000. They look like bicycle wheels but with center lock or patterned for lugs. Gives you more room in the trailer too since the wheels are much skinnier. The tires are solid so you can strap down as tight as it will go. Also, look to Avon for tires, worth every penny and a solid service life for a weekend warrior. Can’t wait to see more formula content!
@@AkiUwUx3 What I do with my side by side so it'll fit in my garage. I just leave the 50s covered on the trailer until next time I take it out. Does stuck putting on and pulling off couple hundred pound tires every time you go ride but that's the name of the game.
Easy way to make a transport wheel is cut a piece of 3/4" plywood into a circle, drill a hole for the center and holes for the studs. If you want make them big enough to stretch a bicycle tire over them and staple. Also make them as large as you can while clearing the side pod, makes it way easier to load into the trailer with the additional ground clearance.
2:45 A lot of people may already realize this, but Assetto Corsa is a really good sim. It has some of the most accurate physics you can find in a racing sim, and the force-feedback it gives for wheel setups is also really good. With CSP and Content Manager, its definitely my favorite driving sim, espescially in VR.
Watching Dr. Dahm deal with Weber problems (my problems) put a smile on my face Idle EGT was high because something obstructed your fuel passage to the idle circuit on one half of the carb, making half of the engine run lean under ~3k until you corrected it (revving it out.) Check out your fuel filter! Maybe go to a more fine micron rating. 🤘🏻
One time I forgot to say it wasn’t going anywhere and I couldn’t quit thinking about it so hard that I pulled over within five minutes of leaving and discovered that I had missed a tie down and it indeed might’ve gone somewhere. Say your load blessings everytime people.
Rob, ratcheting over the tires won't hurt them. What I always did for hauling my and ,my customer open wheel cars (FF and F2000) was air up the tires to 25 psi before loading into the trailer. This gives you a bit more ride height making loading easier but also makes it a snap to ratchet down the car with straps over the tire. Then trackside when you go to set tire pressure you bleed the tires down to the required pressure. 25 psi isn't too much for the tire and won't hurt them in any way. Next, DO NOT tow a car in gear, any car but especially a Hewland gearbox. Remember they have no synchros, just dog rings and the gears so if you tow in gear any movement applies force to the gear teeth. Towing wheels are a great idea, get yourself a set of cast aluminum motorcycle wheels and on your lathe make adapters to fit your hubs, then weld them together. Lastly, get yourself a spare nose, nose bar and front wings and a complete rear wing assembly, mounting struts and all. The bent nose bar you straightened is junk, toss it in the metal recycle bin as it will bend again from downforce. Ask me how I know..... :) By having a complete spare nose with wings ready to install you won't lose a day at the track from a simple off track excursion or the car coming loose in the trailer! Remember to set the wing angles the same on the spare nose! PS: Those mufflers use lava rock along with the packing material. At least they used to use lava rock, maybe that has changed over time. To be legal for SCCA Formula Mazda/FX you have to use the required muffler, if you aren't worried about that them by all means, titanium!
0:56 the secret sauce is to make custom pyramids that hold the car up in the trailer by the jacking points. Then you can put the straps on proper. You can make them out of wood. No need for billet (at first). I would not recommend using stands. These pyramids should be at the minimum lift point and with a very wide base (to prevent tipping). This is also a tool you'll use in storage so you don't let the car sit on the expensive tires or on the expensive suspension. Mind you, this should be done for every car that doesn't get rotated at least once every two~three weeks. This saves tires, bushings and the suspension (active bits). For myself, i have them where one of the sides of the pyramid base is rounded, i pop them under the car at an angle with the tip wedged into the jacking point, then push the car forward and all four pop into place. Saves time when you "load" the car. Obviously, taking it off requires a jack).
When my Beetle was still on Webers it'd load up like that, misfire, I'd just drive it around and before long the MSD ignition would blast off the fouled plugs and solve the misfire. Basically the weber is a race carb, it hates idling. So often you end up with a compromised AFR at idle, making it load up unless you just get it out on track.
Best video endings in the game lol... great progress on your driving, if your getting to where tires will really make the difference its proof to me your not only gaining time but feel for the car and its traction. I love this car, it looks like such fun to drive.
rob i’m honestly so glad that you are so successful in what you do i’m from australia and i’m already keen to see some awesome aftermarket rotary internals. so glad that youtube can make a good honest bloke like yourself can make a living and spread great information like you are.
It's so awesome knowing you've seen and heard my work in person. I built the exhaust on the FCP euro 850 wagon that you drove with Jacob not too long ago.
I swear the old Mazda comp/Mazdaspeed motorsports race mufflers used Lava rock as a packing to deal with the heat. Maybe that’s what this is and what’s in that muffler? They rattled like a box of rocks and weighted a ton.
I have dual wideband and dual EGT’s on my 13B, and I noticed rear rotor was down about 150°c compared to front rotor, did a comp test and it was just under 50psi on rear 🤦🏻♂️, EGT may be mediocre for tuning but def good for spotting problems 😅
That looked like a Borla XR1 muffler. For how hot the exhaust gets on those engines, especially with the very short run from the engine to the muffler, you might need to look into Inconel.
Hey, Robert. A regular muffler will never last for the extremely hot breath of a rotary engine. The least muffler needs to be built of stainless steel. What would I use? Titanium. The warping was due to the tremendous heat of that engine. The reason the muffler failed wasn't because of the metal that was used. It was the thinness of it that was. Yes, guage wasn't thick enough. Do you know how hot the exhaust is from them? More than 700 degrees fierenheit. The reason why it's so hot is for the same reason as I described to you in the past posts I sent to you.
Honestly can't wait to see you make the formula Mazda better once you catch up with the car. I wonder what kind of suspension and performance upgrades are possible.
I love your videos rob I'm 16 and so inspired to get a rotary because you explain in a way non rotary people would understand its fenomenol. Keep up the good work. Cant wait for the next video I get so excited when I see the notification on my phone that you posted. Love the videos and thank u for the knowledge.
I did what you did to your muffler on my cr250 once the core turned red hot in the silencer and burnt the fiberglass packing enough it started to clog it.
Hey Rob. Never ever should you transport a car while left in gear! Have seen many a gearbox ruined by doing this. The constant rocking back and forth will imprint the bearings onto bearing spacers shafts and gears and then they can fail. Have also seen gear teeth break off!
if your transporting a vehicle in a trailer, id say dont put it in gear but keep the handbrake up, wouldnt wanna mess up the engine/trans from back and forth forces, and more ratchet straps lol
please get a hans and lighter helmet 😊 for example an fiberglass arai gp7 weights around 3.5lbs how much does that racequip weigh 5 lbs? makes a big difference for driving
Not how that works, if anything that will add more inertial mass behind the rear axle. The reason his rear end is loose is that he fucked up the rear wing, doesn't have it set correctly anyway.
It's a $15,000 car, a racing license is a $600 weekend with MCSCC and it's valid for SCCA. A typical race weekend will run you about $500. YOU can do this, even go wheel to wheel, instead of the parade laps you're watching here.
Hey rob i work for a carbon fiber weaving company if you need need raw carbon fiber they sell nationwide and we can do any patteren and even program a rotor shape into the weave
That's pretty sick I didn't know you could program shapes into the weave I'd assume that's a rather expensive add on tho
bro that would be so fireee
I need to see that! Please rob collab with this dude

Avon is sadly quitting their tire production, But a company in the Czech republick has bought the rights/tools and will produce their tires again.
Hoosier R35 has been my favorite tire I've put on the FM. The R20 is even stickier but will overheat if you're not careful.

I bet you forgot to say "That's not going anywhere" when you finished strapping down the car!

Just strap to the front and rear lower control arms. Hauled my FM like that for 3 full seasons of racing never had a single issue.
The ol' oak tree mandrel. Works every time, 80% of the time 💪
“Yeah titanium”
Oak tree you're in my way
How to end a video:
"Yeah titanium"😂😂

Make sure to fix the wings before your next outing. A wing without it's shape isn't a wing.
Love the formula Mazda, need more videos of you driving that beautiful beast!
Everyone: "Dude, you're on fire!"

Been waiting to see this thing in action again!
It's so awesome knowing you've seen and heard my work in person. I built the exhaust on the FCP euro 850 wagon that you drove with Jacob not too long ago.
Mufflers and ignitions are wear items. Guys would pick up 5-10hp after refreshing them, usually before big races like June sprints or the runoffs.
The 'yeah Titanium' at the end was so wholesome.
It took me more time than I care to admit to realize this is Buttonwillow.
It's so green!
I swear the old Mazda comp/Mazdaspeed motorsports race mufflers used Lava rock as a packing to deal with the heat.
Maybe that’s what this is and what’s in that muffler? They rattled like a box of rocks and weighted a ton.
3:56 sounds like an old snowmobile I used to have.
I was right behind you in the GR corolla when you went off, cool to see you out there. That thing sounded good
If it didn't break,blow up or catch fire,did Rob actually drive it
bro is the nicest guy in the world . wishing you nothing but the best .keep grinding brother

That dmg to the wing did not help the tail happiness of the cart
Thar rear wing was...not right. Most of the open wheel formula cars are meant to be a bit tail happy even when the aero is right.
Now it has proper AeroDahmnamics!
Hey Rob, I was curious what factors go into the decision to have videos like this be so short compared to your deep dives
Can't wait for Pike's Peak!
you know with enough airflow it can cool the exhaust and push any impedance out, so I feel like a turbo would really cool things down
PIKES?? Congrats from the Volvo community can’t wait for the day to come
Damn man not used to seeing Buttonwillow that green!
Honestly can't wait to see you make the formula Mazda better once you catch up with the car. I wonder what kind of suspension and performance upgrades are possible.

Is this close to formula Pro Mazda on iRacing? I love that car :)
No, totally different cars.
I want that thing so bad. I would have nowhere to use it but I want it 😂
Nice sharing Vidio 🇮🇩🏎️🏎️😍👍👍
2:45 show us your sim rig man!
Dude looks like so much fun
The reason why the front wings are design like that and so you can adjust the angle of attack .
what is the width of the front and rear wheel track?! (thank u)
gopro pov footage of you racing pls
That’s a true full send 🔥🤣😂🤣😂
Please sir can I have some more?? Lol. Rewatching the vette build cause I am having content withdrawal!!
When did the formula get a rotary?
Rob,I love you man
When you say it was sound,taste and feel…………..
How do you think we did it before computers
Lmao
You rock man 👍👍👍👍👍👍👍
Can we see you build a nice exhaust for this plz? Titanium ❤
Hey Rob. Never ever should you transport a car while left in gear! Have seen many a gearbox ruined by doing this. The constant rocking back and forth will imprint the bearings onto bearing spacers shafts and gears and then they can fail. Have also seen gear teeth break off!
Lots of the FM racers use lava rocks to pack the muffler
got a link to that assetto corsa mod Rob?
"it needs redline" this fucking kill me 🤣
Sick
We miss you Rob
Over the tire straps for the e- track. And spend 120$ an real straps
it being tailhappy, does that not mean a better rear spoiler is needed?
Notification squad!! 🔥🔥🔥
You need transport only wheels for all your cars to overcome the issues you experienced car
we need pov driving footage!!!
Titanium ❤️
Hey Blake. I mean Rob!
aww I was expecting for a 40min vid
Fire, huh huh huh, fire...
Is there a reason you’re still running points?
Its not points, it's a distributor with electronic ignition.
😂😂😂 what better excuse for some carbon bits..... just make sure you use wheel chocks that way there won't be any trailer suprises 👍
Neat!
if your transporting a vehicle in a trailer, id say dont put it in gear but keep the handbrake up, wouldnt wanna mess up the engine/trans from back and forth forces, and more ratchet straps lol
Hand brake? This is formula car.
12 rotor content

It'd be cool and ironic to use a C5 Z06 muffler since they're made of titanium.
TWELVE rotors?
What track is this?
Buttonwillow Raceway Park
Formula Fire Ti; I like it.
I have a throttle body that would fit on the Weber manifold. I want to give it to you, Rob. Let me know the PO box or whatever you use.
@RobDahm 100% seriously.
if rear end is loose, a heaver exhaust might not be bad to keep more weight over the rear tires.. just a thought...
Not how that works, if anything that will add more inertial mass behind the rear axle. The reason his rear end is loose is that he fucked up the rear wing, doesn't have it set correctly anyway.
Lets gooooooo.
Rob are you doing alright?! What do you have cooking up, it feels like it’s been a month since you posted anything, just checking on ya 😢

The only issue with this video is that it isn't 30+ minutes long
3 rotor and time attack mods , when?
Just goes to show how light that car is when you don't feel it banging around the trailer.
smh rob, this is why you should always just drive the cars to the track, cant damage them in a transport trailer then :P
It rolled? SEE, that's what happens when you don't do the "that's not going anywhere"
In dahm we trust I'm going to keep saying this
It really sounds like a small go-kart
