Imagine the delivery guy "hey mate, here’s your brake discs." "Nah mate, that’s my engine block"

The teaser at the beginning made the promise of seeing you smash a brand-new $2700 billet rotor housing with a hammer, but there was no such demonstration in the video. I want my money back.

Just when sinking all your money into the rotary game couldnt be easier they up the stakes...

I love you guys so much, keeping the rotary engine alive and making it better!

This part could be manufactured cheaper, simpler and stronger with the correct choice of cast iron. However, if you are looking for the weight savings too, that’s a solution. The cast iron OEM plate is brittle, however nodular cast iron (Durabar) is much stronger, thermally stable, and has vibration damping properties. Durabar 100-70-03 or 85-55-06 is a good choice for this application. Between 55ksi and 70ksi min yield, with low elongation is superior to the common 6061-T6 aluminum specification. This may also be 2024 or 7075, made an assumption. The one piece design does simplify things.

Aluminum is not stronger than cast iron. the problem is cast iron is less ductile so it tends to bend rather than flex/bend like aluminum would. also casting impurities and internal stresses from the casting process can cause problems. not saying that these billet aluminum end plates aren't more durable than cast iron, just pointing out that you're incorrect when you say the iron is "weaker"

I love that this part has a replaceable iron part that is similar to a piston engine sleeve. An RX-7TT tends to need frequent rebuilds, so this makes perfect sense. Although big diesels tend to go a long time between rebuilds, they have swappable cylinder liners because the manufacturer knows the engine will get rebuilt more than once. 9:00 Iron engine parts are weldable, but it takes a great deal of skill and time. That is why it typically is only used where rebuildable cores are almost non-existent.

Be good to see a comparison with Billet Pro, Billet by Pac , Billet Boss and Billet inc.

Thanks Fullboost keep on pumping these vids!

#BILLETTHEWORLD 😁

I've always been nervous about using an engine stand on these motors. I've seen irons crack and I could only come up with it spending too much time on the stand. Glad to see a solution that will also help with the weight.

I love all of these material experts in the comments. They seem to forget key aspects of the aluminum that are actually beneficial over cast iron when it comes to thermal stress. Aluminum is a FAR superior thermal conductor compared to cast iron. Strength? 7000 series aluminum is the strongest grade of aluminum alloy on the market, and can be precipitation hardened. This stuff is used in high stress applications like aircraft frames. I wouldn't be worried about it...

That’s SICK!!!! Keep the rotary alive!!! Thank you

Another good video, you are killing me sliding that virgin aluminum end plate across that crappy steel topped bench, who doe,s that ?

Another fantastic video. Keep up the good work FB and RRC

Cool video. Thanks for this information. I would love to see more.

I so bad want to make my ND MX5 into a lighter, daily rotary cruiser. Australia has world class rotary professionals, its so tempting!! I wonder what it would cost for a full conversation? 40k+ 220 kw sounds about right. Love your work Fullboost! 🙏

12:55 Jordo and Broomy. 🤣😂 I'm dying from that boys, that was hilarious!! 🤣😂🤣😂🤣😂🤣😂 Holesaws and JB Weld FTW!! 😎😎😎 That split plate though, what a shame. That bridgeport looks huge and beautifully ported too. 😖

I was actually thinking of buying a Mazda RX8 since they are so cheap but no way after watching these videos. Thanks for saving me thousands of dollars.

And how much is this kit I know when I went for lower compression rotors it was stupid expensive

Dear God! “50+ pounds of boost” ! Insane power levels!

Cast iron is good for static charge. It's fragile because of high percentage of carbon (comparing to steel). Like any other material, it has advantages and disadvantages. Thank you for this video!

So true guys with the billet stuff i caught my 626 on fire when the front plate decided to crack on 30psi by mistake but fuck it went hard 5th gear wheel spinning. great watch as usual thanks

Happy to see aftermarket for these quirky engines. Will there be rotor housings availible as well?

this is helpfull video . Thanks Dude!

wew didnt expect those feels. rip rich piana

Are these the equivalent of a solid no dry drag race only block?

Mean as bruvs love it👍

love your videos

I believe that the Racing Beat aluminum 13B end housing is probably a better way to go than the Billet Pro. It's actually a cast aluminum part with a flame sprayed face - the flame spray is much harder and, because it's ceramic, reflects some of the heat back into the combustion chamber.

Billet rotors and eccentric shaft would probably make more power tho right? Should be alot less weight to move around.

Question. How many miles can the the average Billet Rotary FD take on a daily driven RX7 before the engine goes out?

*Do they Forge the Aluminum before milling the Billet..?*

Rotary parts are so compact, why not just forge everything? :o

Whats the weight differance between fd block and your aluminium block?

So technically you can replace the plate with pre cut bridge port plates etc? Also why bother with the normal intake ports when going billet instead of just going full PP from the get go?

Lets be very clear, billet aluminum is not stronger or more resistant than iron. It can and does warp and is susceptible to stresses like anything else. Cast blocks ect crack, thats their downfall and they are heavier. They also rust. Billet gear is used for race builds they are not practical for road use and longevity for 100k + applications and daily use.

Why does the ally in the exhaust port not melt, with the high-temp exhaust? I note that Rotron use inconel exhaust pipes, because of high wankel exhaust temperatures. R

you really sold me, I'm getting one for my corolla

Could buy a LS and hang a turbo off the side, for the price of the rotary engine and make half the power what's the point?

What about heat deformation of aluminium compared to steel? Aluminium has a coef of dilatation approx 2 times the coef of steel, don't you think this can be a problem in super hot engines like the rotaries?

With the kind of weight to power ratio along with their reliability, I'm wondering why your not seeing them in experimental aircraft.

Good job🌷

How long does a Billet rotary engine last in driven kilometers without being rebuilt ??

How cost the engine (short block)

Awesome video! Thank you for the information. I love billet

isn't a line bore with all new larger studs better ?

Where can I buy a billet dunny?

Sorry I don't hardly know anything about rotarys. So these are the end plates? Can you get the rotor housings out of billet?

so the rotary wont breakdown with the billet?

The machining model is open source for that plate too so can easily be machined at home...

Does anyone make billet MSP parts? All i can find are billet REW parts and to be honest i'm not keen on switching to REW.

So excited cause BILLET = fullBOOST fullBOOST fullBOOST fullBOOST

Man that boxing is sexy I'd buy the plate even if i don't have a rotary

You have made a pretty broad statement saying Aluminum is stronger than cast iron. It cant be to bad as there are plenty of engines getting around with cast iron cranks. Aluminum cranks i would say never twice. The rotor chamber end plates on the Aluminum example has steel inserts? So they are secured against end float with a LH/RH threaded bush . Is that all no other locking? The only concern really is the different thermal expansion rates as it is all sandwiched together. I'm thinking end float of the rotors being changed at different temps, water leaks internally. A scratch in the dirt calculation shows Aluminum expands by about 1/3 more than steel at a given temp. About 15~20 years ago the CSIRO created an Aluminum matrix with Silicone Carbide by combining the powders in a ball mill then melting it into a solid. . The stuff was hard and strong enough to make brake rotors out off. It had far better thermal properties than steel but was difficult to machine and tap. This material would take a good ground finish, not need hardening and could be cast the same way as high silicone aluminum (wheels) .

when someone makes a billet rotor or rotor housing ill be impressed. Problem with rotories is your hampered by a lot of factory parts still needing to be used. I'm no fanboi but i do like rotories for what they and the results people have gotten out of them is impressive

I wonder how much a resurfacing would cost. I'm guessing less than $2700. Also how much is a new insert for the billet?

If apex seal and housing were made of stronger metal would it be any better

That bridge port on the cracked block is so skinny on the bridge, wouldn't have done the corner seals any favours, impressive that it split the whole housing like that !

hope the material specs are correct .. else it will suffer pitting and warping

*GREAT explanations. Robust, DURABLE parts don't create power* *But they do ... enable power you can create ... to be created reliably* *What good is being temporarily 'first' provide if you can't finish the race..?* *Curious: Were the CAST plate BRAND NEW ... would it still be that brittle..?* *Did heating cycles ..? induce a change in material properties (annealing / work hardened) ..?* *If the latter, can aluminum undergo a similar change (annealing I believe) ..?*

While the billet part is a beaut, and I wish I could afford them, to be very real: 1. The reason for all those bolts is because it is aluminum rather than Iron and it simply needs more bolts.. aluminum deflects a LOT more than iron around that circumference. 2. Regarding your comments on strength, an Iron part is (without question) stronger than an identically dimensioned aluminum part. - The key here seems to be rather that: 1. the aluminum part is not as stiff (e.g.: it can bend more than its iron equivalent, meaning it will take equivalent shock loads without cracking) and 2. it is easier (and more cost effective) to bolster the dowel loading area with more (shock resistant aluminum) material in the billet part without exacting a weight/mass penalty (i.e.: rather than a casting, it is less work/cost to "add material" with billet simply by not removing material where it is not impinging upon some other dimension, since machining is an extractive process). Also, it should be said that production restrictions/requirements are vastly different than custom parts... in Production, a few pennies of savings in one area may save the whole production line.. or enable some other (completely unrelated to the specific part) element to be incorporated (into the car, as a whole). The blissful disregard the aftermarket gets to wield, compared to the constraints of the factory, is wonderfully non-compromising in functionality (at the cost of...well, cost). :-) None the less, you guys do a great job of explaining and detailing all the ins and outs of these engines. THANK YOU for keeping the dream alive :-)))

Do you produce these for the msp without the side exhaust ports? Any plans for msp rotor housings with a periferal port exhaust and 3 oil injectors?

When they smash embin? Thank

What is the weight difference?

Who makes billet pro plates?

how a maksium hp a billet blok

Broomie the little rotor jockey:D

how do they put the Chrome on aluminium?

Fexcellent!

Now hit the billet one to compare

Rich Piana is actually a good metaphor for the longevity of the rotary engine. Godammit..

Heat distribution???

If I would want to run naturally aspirated 500HP or 600HP reliably, should I buy billet plates or stick with the cast plates ??

Can I get this in the US ?

Do they offer bridgeport inserts?

What about a titanium rotary?

Sure would Love to bring My 78 FJ40 & 04 RX-8 Down Under for some Relaxation ! Fine Craftsmanship Folks , save Me a Couple BARRA'S TOO 😄🏁 Thanks Jimmy

Have you tried to 3D print a Titanium one? Aussie has the tech...

The centre insert is replaceable? seems like something to work its way loose.

Put some ceramic coating on the insert, micro holes holding enging oil. More mileage to go.

Bridge port/ Street port inserts? Peripheral ports?

I owned a Mazda RX-8 for nine years. It was a cool car, but I eventually got sick of it. The two things that I got most sick of were the exhaust noise and the fuel economy. Yeah, it's a sports car, who cares about fuel economy, right? But when a piston engine car can make the same power with greater reliability and 50% better fuel economy...all I can say is my enthusiasm for rotary engines only extends so far.

Isn't billet cast then forged metal?

It must cure a lot of the water seal problems that are caused by different expansion rates of cast iron and aluminium.

$2700 isn’t a bad price. A billet rAce V8 block is what $20,000-$30,000?

POG HOUSING INSERTS WAOH NEW ROTARY ERA :D

Do they make these for Rx8 engines?

I love that you can remove the face of it, great engineering

There will be a time when they start producing end plates with 3d sintering.

Show the boost increase difference on the Billet

Haha finders keepers 👍

Billet rotors and center plate // e-shaft when??

"why you need to give us your whole wallet"

I want to rebuilt my S4 NA all Billet in stock spec just for longevity 👌😂👌

I'd love to see a single blade made with this.

the on thing I thought about is, cabon oxide tempered steel block & mill it down ( gonna be $4600 for one plate, )

That billet steal insert should be a ceramic insert for longevity and while there all wear surfaces should and can be ceramic but I suspect no one will do that . Can you imagine longevity then and cooling issues would almost be not worth worrying about again
