For those that don't know, "Billet" is latin for "Compressed Money", it's a process that requires vast amounts of cash be compressed in a press until it solidifies, then you use special tools that are also made of little harder material, during this process things become very shiny, however if there is a mistake in the process, all of the "billet" vanishes, normally associated with "Tears" and a Eating a traditional meal of "Ramen" for 2-4 months.. all of these can be part of "Racecar"

[@CS_247]

😂 this man is well educated in the language of racecar...

[@bwalker4194]

😂LOL! And if you want to make a small fortune with your Racecar, you better start with a big one.

[@jimhmod]

I think "Billet" and "CNC" are somehow connected with this theory😁

[@LEOhopeful]

Two years of high school Latin, and countless years of ramen...can confirm! 👍🏼

[@baddaddy8718]

After 32 years of building my racecar I can confirm this billet theory. All the forged stuff doesn’t work under load, must be billet and heavily heavily offset by years of ramen 😂

One of the best thought out engines I’ve seen… nicely done. Probably only one in ten thousand will appreciate the work done in the development phase, but the end product shows the effort. You got it right, crank pin overlap lowers counterweight flange load, longer sleeve keeps the piston gage point up inside sleeve, inboard pins… very good job on this and all your products. Bravo Zulu….

Your commentary on how it goes with custom stuff is true. I work for a oem supplier just down the road from you, and we spend a fortune on prototypes that often all need custom fitting, and that's after countless hours of CAD, design reviews, FEA analysis, etc. The 1st parts always take a lot of extra, unexpected time. Management is always baffled as to why.

I see the SMX and SML being used in offshore boat class racing. You have put a lot of thought into the design of both of these motors.

[@bigduphusaj162]

boats like you are talking about need a 100% engine. Meaning it can run all day at top RPM. It's quite hard to convert a car engine to a marine engine tbh.. its easier converting a marine engine to a car engine. 2JZ was originally supposed to be a marine engine

[@MrMaxEffort]

All the engineparts in the SML and SMX is bookshelf materiel, it's so nice finish on everything.. Well done Steve and crew and of course Drew..👍👍

[@silkysixx]

On mains: steel caps go on iron blocks (maybe) and aluminum caps go on aluminum blocks. You're 100% right that the thermal expansion is important to consider, even in the bottom of the block. I am always baffled when people neglect to think about this. Regarding cross-bolted mains, the shear strength of the bolts is no more important than that of wheel studs or converter bolts. By clamping the skirt of the block against the end of the main cap, a lot more friction is applied in the spot, which is what actually contributes to the cap staying where it's supposed to. Your splayed design, however, would also apply some friction to the end of the cap and also adds regular, old, tension force to hold the cap up in the block. If the shear strength of the main bolts was relevant and relying upon it was a problem, then splaying the outer bolts would present the same problem. Really love how much detail you go into with these films, especially considering it's about a priority design and your own invention. Very cool and a boss move.

[@danielchilinski2110]

[@maxwellyedor7610]

Hard to overstate how impressive this whole operation is. Seriously high level design and machining, as a guy who designs stuff that goes to space, and works with some of the best aerospace prototyping machine shops around, Steve and his crew are doing it at a higher level than 99% of the guys in my industry. The missed thrust bearing counterbore and having to go in there with a 90 degree milling head cracked me up because I’ve got a stack of gimbal mounts with the exact same issue in the shop right now. Shit happens, that’s why there’s red dykem, mark it, fix it, move on

[@SCARFACE69247]

The way your brain works to problem solve things is what keeps me coming back. I'm sure these new engines will cause other unforeseen problem which I will be here to watch how those issues get resolved as well. I'm happy to see you finally got your transmission issues worked out!

[@mrgrantham4475]

Hey Steve, have you ever considered engineering an Opossing piston engine to push the technology further along?

[@ryno6101]

Thrust surface like that was cut with a bar thru the block with bushings in each bearing bore and a single high speed steel tool with a long enough cutting edge to cover the whole needed surface, the bar was driven by a spindle in a horizontal milling machine and slowly with Lube fed into depth. On roughing tool bit was taking only half way out to diameter. What you’re doing is called circular interpolation Awesome engineering, thanks for sharing ❤❤❤

[@stevemorrisracing]

😁

[@threadtapwhisperer5136]

Circular interpolation being the specific path of the tooling? Akin to Trichoidal milling paths, but a obviously different mathematical formula governing the movement? I don't word so gud, what them thar many syllabic words. Haha! Thanks in advance!

[@tmr626]

That aluminum block is a thing of beauty. Back in the late '70's or early '80's I was sending ideas to Mr. Gasket hoping to make some extra money. At that time Rich Preston was the head of their R&D Dept. One idea I asked them about was: 1) Why can't roller lifters be used with hydraulic cams? 2) Because of the cam friction using solid cam bearings I sent a drawing and suggestion about using needle bearings on the cams. 3) It was also my suggestion and drawing of using an air filter in place of a steel/aluminum top carb cover much like K&N etc. is using these days. There, I feel better now!

[@bigduphusaj162]

they filters were already about back then mate. Im in the UK they filters have been about forever.

[@tmr626]

@@bigduphusaj162 Hi there! It's probably been close to 50 years now when I first sent those air filter designs to Mr. Gasket in the '70's. It got to the point that it's hard to remember the exact date. At that time I don't ever recall seeing them on the market. Back then, I use to buy just about every car and motorcycle magazine out there so I would never intentionally rip off someone else's design. Too much bad karma! Take care!

[@baddaddy8718]

I been fortunate to grow up in a racecar area (Bathurst, Australia) and even here with all the interest and tech on our gear I’m yet to meet the Aussie Steve Morris. Sure, we have names like Perkins and Sainty, and in the 90’s had stacks of alcohol racing success and touring car success but nothing even close to the 3000+hp streetable engine this guy has designed and built. Rilliant engine from a brilliant man!

[@miceinoz1181]

Utterly bloody brilliant Steve. If this is not a good explanation of why your engines cost so much, then I do not know what is. Attention to detail is everything in performance engines!

[@FoolOfATuque]

Definitely since you have a machine shop it makes sense to figure it out, but we sub-contract our parts so it has to work. Our tools are not nearly as complex as an engine either so we don’t have complex interactions like this. We also have a saying that everything works in CAD. Just because it works in CAD doesn’t mean it works in real life. For people wonder about why Steve is needing out about big radii it’s because of stress concentrations. The bigger the radius the less likely it is to break at that point. This is probably especially important in a vehicle since it sees a lot of heat cycles and has harmonics. Stress concentrations lead to cracks and cracks lead to broken parts. Very cool!

[@bumpedhishead636]

Steve: Have you ever talked about how you got where you are today? Where did you go to school? Have you always been in the automotive industry? Always in racing? Where did you learn about engine design, machining, CAD/CAM, etc? Why did you decide to design & build engines? Why LS-based engines? How do you decide when to use an existing component vs designing & machining your own parts in-house? A bio video would be very interesting!

[@chozgarage2023]

As I catch myself wanting to dive at the tv because your insert is going to fall while you crank it around and I yell “stop!”…. Nice cut.
