Billet Turbo 5 Rotor - SLC Superlite - Intake/Exhaust Fabrication - 106mm Turbo

[@Snekul_Xfire11]

This is literally a work of art. Your projects spare no expenses or cut any corners. I get inspired to sort out even the smallest details of my build as a result of following your vehicles.

[@droopydoop]

An absolutely beautiful build...

[@DETHdressedInRED]

It's like gearhead porn lol.

[@CorpseExplosion]

Mind blowing! The design that has gone into that stand-off platform for the intercooler core is wonderful. When I watched it kinda 'click' into place on those rubber standoffs....I think anyone watching knows viscerally what that feels like and it looks so satisfying! Just impeccable.

[@crazylegolas823]

Absolutely insane build, can't wait to hear it run!

[@VS666]

hell fucking yeah dude, so freakin' stoked on this build!!! i just got a 2 post in my garage and i'm itchin for a project car, i could only DREAM of doing something this wicked!!!!!! every inch of this car is an engineering and fabrication wet dream

[@rotaryperfection]

An equal length 5 to 1 exhaust in such a tight space? I don't want to be that guy trying to fab that. Good luck to him but i'm sure it's already come together and will sound perfect. Can't wait to here this thing rev. Edit: If anyone is wondering, splitting the exhaust post collector, won't effect your sound. The pulses are already collected well before hand. My NA 20b has dual exhaust tips that equally split post muffler. If you'd never seen my back side, you could never tell it had duals.

[@jdmimportlogistics]

Man MF5 just rocked the whole car world again! Can't wait to see what this car will do on track and the evolution over time-Brilliant work Sir!!!

[@Real_Richmond_510]

Can't wait to hear this thing fire up for the first time! 🔥 will be pure bliss listening to the sounds it will produce from the harmonics of the 5 rotor timing and every other sound resonance the environment around will produce! This is a thing of beauty! Do you have the 4 rotor doing anything this year for us in the meantime? We would love to watch and hear you shred the 4 rotor sometime soon! How long do you think until this slc will be completed and driving?.... 2k24?

[@alexkarlozi2174]

pretty sure he sold the four rotor to fund this project. I could be wrong but I think the guy he sold it to also has a youtube channel or some sort of content platform.

[@IM4UCKEDUP]

I forgot about this car not sure why never popped up in my feed notifications are on

[@DM007x]

Your SLC is going to be absolute perfect... The guys at Waterford Hills would be blown away to see this on the track when it's done

[@NeoIsrafil]

Damn, rob dahm builds a 4 rotor, and suddenly you're after a 5! 😂

[@TkTalko]

This build is unreal. Absolutely amazing work❤

[@SuperfluousIndividual]

A day with an update from David is a good day.

[@geraldbolum9422]

Can't wait to see this beast come alive!

[@isaacmoore3285]

I love following this build!

[@markwernet]

Appreciate the time you take to talk us through it, thanking you. 🙂

[@cncdan1364]

4:37 and that’s exactly why every one live rob. He Durant hide anything. He wants everyone that loves rotary’s to be able to have the strongest best motor they can

[@dzmazzei]

Anyone who would like this information is welcome to reach out directly and demonstrate their willingness to collaborate/exchange/communication however there are certain things that take great costs and time which we can't freely give away

[@tunjungrestya3402]

we wait until the process is complete ❤

[@amyasseektruth8246]

When this vehicle is complete... it's going to destroy hyper cars - Mazzei Formula is taking performance to the NEXT LEVEL - absolutely A-Mazzei-ING ------

[@ImKairyu]

this car will be remembembered forever as one of the all time greats during the combustion car era.

[@DETHdressedInRED]

Man every time I see these videos I'm like DUDE JUST FINISH IT ALREADY I CAN'T WAIT TO SEE IT. I wanna hear this monster so bad... Please if you ever do a tour with it bring it to Colorado... I'll drive 300 miles to see that thing no problem lol.

[@shastrigibbons637]

Thats why i rock with dahm ...hides nothing share all information

[@dzmazzei]

That's ok I still appreciate you taking the time to watch my videos and comment!

[@Grooty79]

David this car is so next level, im loving this build and the fact its single turbo 5 rotor :) cant wait to hear it

[@BrunoSantos-kw2se]

Força

[@conquerorhowie]

This is such an amazing build. I can't wait to see you takikg it for a rip. I hope I get to see you driving around Birmingham 🙂

[@clubsport9334]

I love this, is the intercooler core big enough to handle the massive intake temps and air flow this thing is gonna produce? It's seems kinda small. No disrespect meant.

[@xilix]

Jeez... this is gonna be serious. Be careful drivin this one, man. Stunning work all around. Just gorgeous.

[@xilix]

Jeez... this is gonna be serious. Be careful drivin this one, man. Stunning work all around. Just gorgeous.

[@SleepySolo88]

This Just On Some Other Level And Pure Perfection. I Still Watch The Old Videos Of That Beauty Of Art Work RX-7. IDK It's Rob Dahm Or David Build. They Put A lot Of Detail And A lot Of Blood, Sweat And Tears. This Beauty Going To Be A Monster.

[@masmas6846]

Absolutely glorious!! This is beautiful, functional, and meticulous work!

[@hooverbuc6726]

This car is going to heat soak so bad from the exhaust being that close to the frame and he doesn’t even realize. He needs to move that turbo up away from the frame. I help a guy that has a 1988 Rx-7 IMSA GTU car and the inside of that car gets above 160°F after doing 5 laps at Barbers. MOVE THE TURBO UP. It does have to be much just 1/2 a inch.

[@swurbxy]

12/10 stoked on this. Probably going to need some gold reflective tape and / or additional heat protection between the turbine housing and the bodywork. I’m sure you already have plans and will have it sorted.

[@dzmazzei]

Definitely!!!!!! Most likely will do all of the above and a turbo blanket

[@sepg5084]

Ceramic coating on the exterior of the intake runners to reduce the rate of heat seeping in, and on the interior of the exhaust runners to reduce the rate of heat absorption by the runners. Then a turbo blanket and maybe some exhaust wrap, if they don't heat soak the metal too much.

[@scotthodges5214]

Question: 106mm is going to spin some serious heat. What are you doing to protect the rear clam from heat exposure considering its close proximity to the turbo itself? Absolutely amazing build so far. VERY excited to see and hear the final product and thank you for all the walkthrough videos.

[@graysonlove27]

I can't wait to win this car during your car giveaway! I'm super excited to rip this around Harris Hill Raceway. Five-rotor turbo with little to no piping. This car is going to f'king rev faster literally than a blink of an eye. BTW - No Y pipe needed with the exhaust. Use Titanium and straight pipe that shit right out the back with a slight angle so all the fire gods can be expelled. LOVE this build!

[@kikiautorcman787B]

You have to show it to Yojiro TERADA San when he comes in USA... 😉👍‼️💯🛢️🔥🏁🏎️🤓🇨🇵

[@johnnygeorgopoulos4072]

Why am I just now hearing about this ridiculous 5-Rotor monster single turbo contraption? 😅 This thing, will most likely, sound absolutely phenomenally insane..... I've been wondering and waiting for someone to build a 5-Rotor since seeing that 6 a long while ago lol. This needs to be street "legal", well, driven on the street 😂

[@stevetold1519]

Sorry snekul_xfire11 I just read your comment and didn't mean to copy you.... but it is.

[@bmxriderforlife1234]

Jesus your slc might beat my planned one for ridiculousness. K48. Graziano sequential mod paddleshift with the electronics to assist in shifting performance. Or a 7 speed sequential set up from a porsche as i heard there is a new 7 speed transaxle. K48 destrokes for revs. 10k rpm redline. Also debored. Thinking of starting with a 4.2 to 4.4L set up. Its hot vee so cznt go my typical twincharger route without doing per cylinder bank boosting. Which might not fit. Keeping vtec. Aiming for a rather high crossover 5200rpms or around there. And a rsther soft vtec kick so it builds from there. Widest possible powerband. From 2000rpms to at least 9500rpms and holding or just starting to drop off to 10k rpms. Gearing planning is weird. Aiming for a high top speed for texas mile but also reduxed rpms on circuit racing and ability to just stay in gear or shift down as desired. Help fuel economy. Idea is get the thing tuned for reliability but also insane volumetric efficiency with the turbos. And 150hp per cylinder but almost 300hp per L reliably. Alot of parasitic losses reductions and friction reductions. Few other tricks im gonna do to get the thing reliable. Hot honing wpc and considerations to toperances and thermal expansion. Rod ratios. And over square or square. Porting design. But gonna have it running multiple tunes and boost maps. And map the boost and torque per gear and rpms. And have it set up to be track mode with real track tires and a street mode where its the limit of street tires plus ability to drift a bit for track days on cheaper tires. High boost tune similsr concept. Able to drift real track tires if desired. Traction control and abs. Plus suspension mods. Gonna see if i can tweak stuff to get spherical bearings to work on a street ish set up. Schwartz steering rack. But gonna see if i can figure out power steering since my engine adds a good few inches of room. Carbon rims. Also going to go the inerter shock route. Know a few companies thatll do custom suspension for not that much. Penske also makes some for drag racing. But idea is reduce unsprung weight plus rotsting weight and increase suspension performance for as much grip as possible plus able to tune it for destirwd characteristics. Standalone ecu plus everything hooked into it even for the other standalones so everything can play nicely and log. No gps speedo true actual calibrated speedo maybe plus a gps speedo. Bunch of weight reduction and heat efficiency stuff. Inconel exhaust but with ceramic coating. Keeping ac and heating. But also doing some other more race type mods. Also live near a wind tunnel that only charges 2000$ an hour. Aero simulation plus a aero engineer doing that plus helping and some quick testing. Gonna do a body modification to support the top soeeds and also improve ducting and other stuff. Modified front bar to better match the window. Added stiffness plate. Once aero stuff is done for a street set up. Carbon version of the body. Plus fiberglass track specific with extra aero stuff. Probably using universal rear diffusers and making sure its basically flat bottom and gets some aero ground effects. Might end up slightly wide body. But gonna do fancy with the ducting up front. Carbon body is mostly for panel gap. Idea is turn it like top tier show car level basically oem but custom eventually. With a target goal of 1200kg or less and 1200hp track mode to the wheels. And 700 more street mode. 10k rpms reliable but not reallt needed to be driven there very often. But like 70mph first gear ish at 10k rpms for crazy 0 to 60 and occasionally easy way to make use. Tuned launch control via two step and traction control. Abs ro help keep it safe and help on track and street. But also able to swap gearing or final rario quickly via differential and other stuff relatively speaking. And tune it a bit more for drag sometimes or circuit. Or even drift. Tryna prevent or reduce unburnt fuel as much as possible as well with a few other tricks. Fueling system is gonna be trick. Tryna play with the texas mile ford gt with power to weight ratio. Like 1000lbs lighter. Only like 800hp less. But can rev higher. Might also make use of a specific texas mile tune with extended rev range since its not gonna be often. And reduce the top speed to something more normal at 10k rpms. But idea is for track able to get to around 230 ish mph quickly and make use of gearing and other stuff to get good lap times. Might end up needing to gearsets for the transmission but oh well. Itll be worth it. But tryna built it to slay bugattis and the other hypercars and be comfy but also quick enough and built to play with real race cars. Plus make it road legal safe enough to be able to travel with it as a show car xD although unlikely. Wanna rip it on the autobahn.

[@saocofd5656]

Amazing job! The rotary passion! Love it. Now, what the hell do you do for a living? Sheesh!!😅

[@longsleevethong1457]

“When installing your turbocharger, insure that the turbocharger axis of rotation is parallel to the level ground within +/- 15°.”

[@BaseSRKI]

This is going to blow everyone's mind! Thanks for the explanation, supercool

[@blackbeardthepirate7467]

I'm more excited about this one than angry Mike's 5R, no favorites though.

[@markcozzie]

Bar and plate misimoto core, you'll regret using that, genuine Garrett core more efficient..epic build byw

[@m.i.s.t.777]

Thank you, the 5 Rotor i am interested for years, especially the sound :D

[@Mightymilo1975]

Hi .. it's really nice work you had archive. Just like to point out on your divider in your plenum I had similar design those divider will end up failing on you my word on it base on vibration and high velocity vacuum. Just like to point that out. This just base on my experience. Best of luck I end up using twin plenum with slim entry divider . If you wish I can send you a final picture of it. Best of luck and can't wait to see the build finish.

[@mrd.808]

Exhaust shape of 5 rotaries will be dope. Because it is a 5 rotor engine ❤ awesome build. Cannot wait for the actual performance figures.

[@Clay_kn4nil]

I'm in Talladega. How do I get a ride in this thing one day? I just have to experience this engine noise personally! If four are great, what will 5 be like? I must know!

[@RRninja-jq6lp]

Mind blowing

[@peterkoch3777]

Gorgeous car, gorgeous engine... 72° We want to hear it and the exhaust manifold roar!😂

[@capnthepeafarmer]

If anyone is interested in one of the SAE papers that David is referring to it is 841017 "Recent Technology Development of High Powered Rotary Engines at Mazda"

[@ajisuleiman1484]

It's extraordinary to make a super car in your home garage but the results are very precise and very good, not inferior to big manufacturers like Ferrari and others ⭐⭐⭐⭐⭐👑

[@GTRliffe]

I can tell you those dividers won’t work air isn’t coming in uniformly for those square dividers to work think of a firehose transiently pushing water to that plenum, the water is splashing every which way dependant on which port is in vacuum. this means, air meads to circulate and wait it’s turn in there..those dividers will only disrupt that phenomenon.

[@S-Kidz]

What if you do the rotor shaped muffler like the Mazda furai? That would be cool racing beat makes em . Just an idea 💡

[@phoenixrising7047]

Man, between the 5 rotor, Davo's slacks and the flashing of those power diamonds at the end I am feeling rather belittled after watching this.

[@bphillips06]

Amazing work by all. Hell of thing David!!

[@richardmg9]

what about just a single fat exhaust with shortest run possible out the back? you could see the fucking turbo blades from behind at the right angle

[@ImOldGregg]

Too cool

[@MrJermbob]

How do you lean our your gut area ? Im struggling and i have a good lean upper body and lower. So hard haha. Love the videos my bro. The car is next level nasa spec.

[@leonardorezende2876]

I m Brazil super car the best rotative 🔼▶️🔽◀️🔼

[@keestojuusto6072]

This will be so sick! Do you have any HP target in mind already?

[@waynewalker3493]

Dave, can you please do another Trumpet intro again???! You need to make it your thing!

[@whyutubewhy]

looks freaking awesome can't wait for the finished project!

[@grumpystony]

I suspect the water to air radiator would create a similar effect to the Audi dual plenum design. Those dividers may not be needed. Food for thought.

[@SilverZepp]

This is some serious money. I know YT is passive income. What’s his main career?

[@seanjones3467]

Been loving watching the build, even when you did the 4 rotor. So the 787b had variable intake runners to make up for bottom end power, has that been designed into the manifold? I noticed it’s tappered. Or does having the 5 rotor make up for that? Also, you gunna let Bryan drive it? Lol

[@tessierrr]

Turbo 😄

[@emeryjohnfrazier]

UNCONDITIONAL GRATITUDE: MY SON & I WATCH & LEARN! WE SHALL CREATE AS WELL: THANKS FOR LEADING THE WAY!

[@danieldecker6396]

I bet you that thing is going to make two thousand horsepower. It would be really sick to make a type of stealth active exhaust exhaust

[@nathanieljones8501]

Can not wait to hear and watch the video when your driving this beautiful car .Did you have to make alot of changes to mount the engine and gear box or is it similar to the Ls and those adjustments drop down etc.

[@pirateradio1926]

Incredible Dave. I love your vision and dedication to making the car that you have dreamed of. You attention to the art is so important, and I now see why you took your time in posting videos. I feel it is critical that this car be exactly what you see it as in your mind and I am genuinely grateful you are sharing your philosophy with us. I pay close attention to the details you explain and hope to take the same build philosophy on my present project. Which similar to yours, is more a piece of mechanical art meant to be powerful but built primarily for the experience of operating it.

[@dendiclaudio4193]

i think this cars is soo underated build for my opinian, people need know what your build broww this is look like jet.

[@shapshooter7769]

Lemme guess? Ultima has too large a client backorder for you to grab a chassis from?

[@dosdahrk4504]

Test tesla valve for air and water movement and cooling brother..it might blow ur mind

[@A_Nub_Scrub]

Definitely following with excitement. Can't wait to hear it scream.

[@travisd83]

But not the first 5 rotor N /A . Mad Mike's 787D is the first 5 rotory from New Zealand 🇳🇿

[@harelrahman9722]

bro,you deserve a statue & temple for yourself,god dammit...i love it

[@AussieBassplayer]

Won't those clamps on the intake rattle like crazy?

[@Kowalskithegreat]

I didn't sit down in my PC chair just to get flexed on like this, sheesh

[@longsleevethong1457]

Pretty sure that turbo needs to be level. It’s gona smoke and burn up in that tilted position.

[@rdcabal]

Can you please tell US how much different is the build from the design? I am guessing not much. And how much that fact makes the build faster and less expensive? I noticed a long break before MF5 debuted on YT.

[@dzmazzei]

I believe you are asking how closely does this relate to the original rendering/idea? It's pretty close! There's a few differences; the splitter is larger, the rear diffuser is added, and the wing will be more aggressive. Can't wait to show you the wing! Thanks for asking

[@MrLobsterhunter]

Next Level! Wish I steal had my 3rd gen.

[@jecthoresp1863]

Awd system for street traction only... Slow version!

[@topdeadcentermoto8319]

Do a 1-2-4 exhaust like a Zonda, then ad a 5th tube for the wastegates to represent 5 rotors

[@kylecurry6841]

Been waiting patiently to to see your next chapter... Can't wait to hear this thing!

[@avevieira7905]

Idea where can I buy the kit from can you give me some contacts and the bits you done to the engine as well thank you

[@redmaus8804]

can you explain how you manage the heat output from the engine/exsaust

[@Soshstar999]

That's going to be a nice ride, it would be nice to see what it could do before you ran out of tires especially if you were to gear it for what it could do

[@vongdong10]

Holy shit. That turbo is the size of a freaking basketball.

[@gregorybolton]

David one question is f.5 going to be street legal or pure track car only ?Because,I'm sitting here imagining kinda sith respect astonished the comotion that f 5 is DEFINITELY going to stir anywhere and everywhere you drive it,e en at the track that car is going to let's just say,...roll off the trailer and before you can say anything your going to be mobbed and all cameras WILL BE FOCUSED ON YOU AND THE F.5!!! COOL HUH!!!??!!! WOOOOOOW. EVEN BETTER YET,... I GIVE IT A RIC FLAIR WOOOOOOOOOOOOOOOOO!!!!!I HOPE YOUR READY WHEN THAT TIME COMES,I'd say get to the track early if you wanna get some time in driving!!! Have much fun though!!!

[@dzmazzei]

Street car too!!! Thank you! So pumped

[@LetsFlyThere]

Oh this guy is taking large dumps on everyone.

[@panikoschristodoulou2471]

Can wait to see this rocket-car on the roads😊❤️💯💪👍👏

[@Flooberjobby]

He's going to have a lot of heat issues with the transmission with the turbo, and exhaust there. Going to hurt his intake air temps too.

[@vagcentral2252]

Will those intercooler cores be good enough to handle your power goals or are you spraying meth?

[@markcozzie]

Intercooler or charge cooled?,, charge cooled that intercooler way to small?

[@TWIXTIMA0]

It already looks like a monster of a car cant wait to see it running

[@trip7shark]

I wonder what the thoughts are about heat management strategies with the turbo and exhaust sitting near the transmission and frame?
