pfft ur lucky you dont have to buy Billet cams, titanium springs/retainers. especially when considering quad cam v6/8/10/12. you can easily 5k on just a built 2j cylinder head with light port/polish. now that there is actually a decent aftermarket support for core engine components it makes them a viable option for high horsepower all out builds while being relatively cost effective in that area. the only downside to a rotary in the racing world was durability at higher HP levels.

[@bigblock3706]

I honestly don't understand blokes like you. What do you expect your engine to do, be honest with yourself? You think it's reasonable to expect to get 2-3-4-5x more power out of stock parts? Why would you think you're entitled to that? There's absolutely no one forcing you to modify your car, no one at all. If you can't afford it, don't do it.

[@77knives]

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

[@PhaseConverterampV]

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.

[@Jupiter__001_]

I know nothing about metallurgy, so this went straight over my head. I guess the 100-70-03 is some mixture specification? Or is it to do with the hardness, toughness and so on.

[@skylinefever]

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.

[@deeremeyer1749]

The "iron part" is not the rotary "equivalent" of a piston engine cylinder bore. The "aluminum part" it's removable from is. Know what piston engines have aluminum cylinder bores? The "disposable" ones you can't "rebuild" as "affordably" as you can replace the entire engine or "top end" from the crankcase up.

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"

[@fullboost]

Yes thank you we know that. 👍

[@trumanhw]

precise nomenclature in tech. fields (i.e., material sciences) isn't intuitive to lay people Vernacular allows people ignorant of such precise meaning to exchange ideas based on _intuitive_ meaning ... though -- I was writing something somewhat similar -- as I wondered if the metal had been annealed from heat-cycles or just overheated -- increasing the "hardness." Which, of course, is counterintuitive bc 'hardness' sounds analogous to _durable_ -- though, obviously, the whole reason effort to avoid metals "work hardening" is bc (I believe) it becomes more brittle. I was actually a little surprised that aluminum can also be annealed. I have to think through what casting means (like a foreigner counting money) to follow the thought exactly. The video (link below) is a fav of mine ... and happens to have been remade & re-released earlier today. It covers the degree of precision required in manufacturing engine components (not rotary) ... it's a very good video. Same channel has another video on the history of the rotary engine... And overall the channel is excellent. Good! writing; better than most edu programs on TV: Not repetitive, very articulate, explains in depth. kzbin.info/www/bejne/d6iQqZWpbb-Krqc Anyway, thanks for your reply - and to the video maker.

[@OddBallPerformance]

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...

[@TWEAKLET]

aluminum accumulates fatigue even small amounts of stress eventually causes failure even aircraft eventually fracture and have to be replaced

[@OddBallPerformance]

@@TWEAKLET which is ductile fatigue, a much different stress than these frames are going to encounter.

[@daveklingler820]

A number of people have had objections to the guys in the video saying that aluminum is stronger than cast iron (not realizing that the extra bearing holes are there because it's aluminum). Cast iron is, generally speaking, stronger. ADI would probably make a much better end housing, and it's stronger per unit weight than 6061. The reason a lot of aftermarket parts are made from aluminum is that the aluminum is easily machined because it's so soft.

[@oldleatherhandsfriends4053]

You realize that aircraft are actually weak as fuck right? They are built to be light and just strong enough not to fall apart in the air. Their frames crack and break and have maintenance intervals that would make people think your paranoid if you did the same for any thing on a road going vehicle.

[@dereksmith3933]

dont listen to that guy about doing ls swaps. you'll spend 3 times the amount of money to do an ls swap right. and if you know how to go about getting a new engine for an rx8 it's really not that bad.

[@dj4monie]

I had the same thought, a RX8 can be had for $500 usually because of some engine problem. But then I found 1) The Renesis engine is best left stock actually and throw it in the corner of your garage. Make the later revisions to your engine if you haven't bought the last of the RX8's, it will mean better reliability. 2) REW or 3 rotor swaps are not emissions legal in California. I can find a way around that but then it's expensive to do a 3 rotor swap and then you run into transmission problems. If I were to do one, it would be a REW 2 Rotor (13b) with a big single and T56 transmission, right at 450-500 hp. Not a world beater but would be fairly fast in it's own right.

[@stevencockerill748]

These parts are primarily designed for Motorsport applications for engine producing over 1000Hp. So not really anything you would need to worry about for a RX-8

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

[@Myosos]

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?

[@daveklingler820]

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.

[@odomis07]

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

[@MrZeddy100]

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

[@dazaspc]

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) .

[@TriXelOne]

totally agreed, the thing here is equal grain orientation, easy to proceed with thermal treatment You can give to a big block of metal, and them machine it

[@bradley3549]

@ChrisHallett83 Somewhat of a gross generalization. You can create very hard and brittle aluminum. You can create very ductile and durable cast iron. All in the formulation and heat treat.

[@dj4monie]

That isn't broad you took it as being broad. Rotary engines we never designed to withstand 800-900-1000 hp which is why racing teams who NEED reliability have moved to billet engines. Normal drivers have no need for that much power especially if you NEVER compete with it. It's just a waste of money to say you got X amount of power but never use it and don't know how to use it either. Keep your iron based 2 rotor car but don't expect much reliability beyond 500 hp, which is plenty of power for an FD/FC/RX2 whatever.

[@bradley3549]

@@dj4monie Nah, he's right. It is a broad statement. Some aluminum is stronger than some cast iron. And the opposite can also be true. Nobody is disputing the fact that high horsepower engines need stronger parts. But the statement that aluminum is stronger than cast iron is simply not universally true.

Not trying to be nit picky but when i hear of how strong Titanium is and its on a par with may be mild steel at it's best.

[@bobbyshaftoe]

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 :-)))

[@deeham21]

What about rotars ? Are people just using rx8 rotars or do billet make them now too ? Cheers.

[@priestleyharker4046]

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.

[@RedRampageOSRS]

aluminum has better cooling properties as well. how do you figure that its not suitable for daily driving?

[@NotSoCrazyNinja]

@@RedRampageOSRS Probably due to aluminum being a lot softer than iron. No experience myself with billet aluminum, but aluminum is pretty soft. However, this application seems to be set up so iron takes the wear, so these plates might be useful, even in street engines. Just might want to stock up on the iron replacement plates in case the company decides to go out of business.

[@Antonemachine]

Man.. No rotary is practical for longevity 😁

[@NotSoCrazyNinja]

@@Antonemachine Take care of it, keep it lubricated, and don't push it too hard and it will last longer than most people suspect before needing a rebuild. Unlike your typical engine, a rotary can be rebuilt rather quickly.

Nothing wrong with billet parts if you need them. As they said is for reliability if you want reasonable power over 500hp ect. In the long run would be cheaper instead replacing parts blocks ect.

[@dj4monie]

Have you priced out replacing iron and rotors? It's only a little bit more to go billet over money and TIME especially spent constant pushing the envelope. The problem is the average enthusiast can't do both. So if you have an older non-Turbo car it would be hard to justify the additional cost. Or you can choose to keep the power level within limits of the OE hardware and focus more on working on lap times or reducing 60 ft or 330 times at the strip.

[@igvtec]

@@dj4monie I'm on about if you just keep replacing parts constantly as I said in the long run it would be cheaper so it would be worth to take that extra bit of time and save up a little bit more instead of doing things cheaper and then 6 months time spend the same amount of money again. Fair enough for the older models that aren't looking for much power and are doing the old cars and carby set ups.

An important fact to remember when comparing the materials is that aluminium is far less stiff than cast iron and steels. Strength is not the only concern

[@deeremeyer1749]

And "stiff" and "stiffness" are not "engineering terms" applicable to generic, random and unspecified "aluminum" or "cast iron" or "steels". Aluminum is also "industry standard" for all pistons in all "modern" spark-ignition and most compression-ignition "high compression" piston engines regardless of "performance level" and fuel type with even heavy-duty "articulated" diesel pistons having aluminum skirts with steel crowns. All of them in engines that aren't "disposable" run in cast-iron cylinder blocks or cylinder sleeves and are installed on forged steel connecting rods with tool steel wrist pins. So obviously "aluminum" whether cast, forged or hypereutectic is plenty "stiff" for piston engines.

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

[@fullboost]

These plates are $AUD 2950.

[@Carlos.Rivera]

How cost the engine (short block)

Who makes billet pro plates?

[@TechnoMonkeyFarm]

Aluminium has poor wear characteristics compared to cast iron and is NOT stronger, the demonstration shows the brittle characteristics of iron, which is also the reason they crack. One of the problems a rotary has, is two different heat zones on the same plane, cast iron handles temperature and wear extremely well. When rebuilding a rotary you should always check the iron plate hasn't warped, so how they solved this for billet, I'm not sure. In saying this, the wear wouldn't be a problem if you're pulling the engine apart frequently, or are doing some treatment method not mentioned in the video. Hopefully someone is working on a ceramic insert or even chrome plating like the housings (no apex chatter to worry about).

@Brad Viviviyal Cast iron is garbage? As in 2JZ, RB26, Bara, S54 and every cylinder liner on the market?

[@thitran2098]

Sir! They are tuner they know what are they saying acurately. Iron cast holding temp more then ali and flexi.

[@TechnoMonkeyFarm]

@@thitran2098 Can't understand you Tran. Breaking off a thin piece of cast iron material doesn't prove one is better than the other, did they do the same thing on the billet plate? No. Even if they did, what does that prove? Ceramics are harder than steel but try hitting your dinner plate with a hammer and see what happens. The only real advantage I can see to using billet is making it "beefier" around damage prone areas (which studding an engine fixes anyway), porting and obviously weight. Again, did they address wear or surface hardness? How about the manufacturer answers this question..

love your videos

POG HOUSING INSERTS WAOH NEW ROTARY ERA :D

[@gidderman]

The billet aluminum gains you lighter weight, its not really stronger then properly made steel, but it is easier to machine...

[@antonismitilineos2605]

Reliability all the way!!!!

[@marvinghearing4859]

Nice! But really it's a performance part. Even in the world of V8s aluminum cylinder heads mean cooler temps and the ability to run much higher compression than stock cast iron heads. I'd compair them to a set of aluminum cylinder heads Not a billet crankshaft. You can get a billet excentric shaft even a 3 piece in case you'd rather run roller bearings in stead of big Babette bearings just saying. Hello 15k rpm

[@ViivoHD]

Doesn't cast iron have a more lubracating effect on the rotor/piston. Wouldn't this aluminium sideplate just make the engine even more unreliable. There is a reason why aluminium piston engines have cast iron inserts in the cylinders.

[@stevencockerill748]

ViivoHD The plate has a removable cast Insert

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

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

[@arvedludwig3584]

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