Unreal. He is a ridiculously good speaker and explains complex problems effortlessly.
Helps he’s a teacher
It’s also edited very well
@@robertmcfarland1816 What technology?
Seriously man...massive information in a small space.
@@robertmcfarland1816Yes, yes like the infinite wisdom of Hank Johnson for example.
You and Steve Morris are too much. You show us reality and how you do it. Amazing parts to make this happen. It all makes perfect sense.
Cummins diesel had a lot of issues back in the 1970's with the cam lobes that drove the high pressure unit injectors. They had to introduce a much beefier "Big Cam" version of the NTC-855 engine. Basically, your car engine valve train is beginning to look like a truck engine valve train. Diesels now run 17 to 1 compression with 40 psi of boost, and last 2 million kilometers.
they also turn 2000 rpm vs 10k lol
As an engineer I listened for a while. I understand the constraints with hardness and brittleness along with toughness and durability. The approach to identify and solve problems with this particular engine is very fun to follow. Always looking for the next weak link and whether or not to leave it as a the fuse or fix it.
@@guyvanbrussel9772 always underestimate and over deliver

It's amazing how loud that engine was even though it wasn't running!! Crazy
Most engine noise comes from the valve train..start you car and open the hood the "engine noise" you hear is the valves/rocker arms be actuated.
3/4 inch pushrod on the exhaust valves looks insane
Can’t imagine what all those changes cost. Worth it I’m sure but a lot.
I bet you could purchase a couple of modest houses for the price of that engine!!
It is really impressive how well controlled they can keep a pushrod valvetrain at fairly high rpm, using close attention to detail. I'm inspired to look into who has build the highest RPM V8 pushrod engine with conventional pushrod lengths (ie not stuff like that Ilmor Indy engine with ultra short push rods). Getting those 5mm Kistler's electronics running right and producing reliable data on a run will be fun/total pain in the ass. Good luck!
Geez, your skills at communicating and educating are off the charts. Great video and a great way to present a complicated topic.
Very interesting facts and information for any traditional car enthusiasts, thank you!
Wow, I really love Camshaft and valve train technology, I’ve incorporated a lot of this modern technology into the old Pontiac engines that I build, a lot of people give me crap for having expensive parts in my valve train, but I have noticed significant power increases using modern spring technology and increasing the stiffness so in my mind it’s not about it absolutely 100% necessary but it’s more about what can I do to make this the best I can possibly make it, awesome video two thumbs up for sure!!
When you are talking about camshaft materials, you are describing "material toughness" the amount of resistance to cracking/failure for high intensity momentary loads. Super relevant here, and cool to see what I learned in materials class make sense in the real world like that.
Always amazes me how much of the "V8 sound" comes from the valvetrain.
Thanks, this is the best and most informative video that I've seen. Explaining parameters and machining principles are sometimes forgotten along with heat cycles. Thanks again for keeping this country running! It still takes fuel ⛽️ to charge an Electric car....
The valve train now reminds me a lot of how NASCAR teams do there head's with the one piece rocker stands and if those motors can zing for hour's at a time really looking forward to how this car is going to run now. I hope now the chassis and rear end can stay with the motor but I've watched this project for 2 years now can't wait to see the #'S it runs now.....
This is one of the coolest, most informative nerdgasms of a video I've ever watched.
This is the only person who has ever talked valvetrain and I understand how it all works very interesting
Excellent presentations yes. You cannot teach what you do not know.. and this cat knows his stuff.. Very well done.
Congratulations to the Sorceress team. She is a very mysterious lady indeed. from an engineering perspective.. This tech will open some doors. Outstanding.
The huge valve lift is crazy that the valves don’t tag the pistons. Awesome job.
That’s pretty amazing valve control for a valve of that size!
I've introduced two of my friends that are interested in engines.
Great presentation on problem identification and methods to address the issues.
I had a physics professor in college with the same talent for a balanced mix of lecture and demonstration.
Thank you.
The sound of this beast holding 8500 RPM is SAVAGE.
Absolute ear porn.
Well boys that's what a cost of a house sounds like.😂
It is so cool that it sounds like a running engine even without the combustion !
Welcome back. Getting Godbold to dig into lobe profiles means this has been quite the project. I had never seen 3/4" pushods in service before.... thing is a beast! I wonder if anyone has experimented with rifleing in larger diameter pushrods to get at both improved flex resistance with lower mass? I don't see square cuts like a firearm uses working, but more of a waved radius to avoid odd stress points [and maybe an extrusion hone for finish]. Somebody will figure that out, somewhere. If I had to guess a starting point for experiment maybe 0.28/foot, but I'm not the smartest guy in the room - could be less. As always, F=ma turns out to be a deceptively simple thing when it comes to making parts live. Really looking forward to this setup hitting the track.
Push rods? They look like drumsticks!
Excellent explanation of limits!!!
Who pays for this enormous project . It really wonderful to see this good job .
I know it’s probably not cheap, but after seeing this and videos from Brian Tooley and his spintron. I feel every high Hp, or max effort race engine should be on a spintron, before it hits the engine dyno…
What an incredible tool! Also job well done! 👍🤘👏
As someone who is designing their own BBC (big block coyote) that will be 642ci. This is all very valuable information. Thank you!
Well after installation of and ,800 lift camshaft in my SBC 360ci motor Competition Cams said I needed to make the horse power I need for all motor Drag racing.
I found issues that were showing on this motor.
And these are real issues
that cause problems on timing as well as breaking issues like they were having.
I would love to see this on my motor.
It looks a lot better here than trying to find them on the Drag strip !
Beautiful engine & great engineering to correct the valve train issues.
Back in the 50s Renault built the little 807 Sierra engine locating camshaft high in the block to use very short pushrods, I cant recall who is building a v8 cam higher in the block but this thing is scary as a sorceress with big wands for pushrods!
I could hear you talk about this all day. Very impressive.
Thanks for sharing it with us
What a wonderful and informative video. Thank you all involved.
One of the best I've come across yet... No ego, just facts... Much appreciated ❤
ABSOLUTE TOP NOTCH, A 10,000 rpm 640c.i. badass mofo
WOW.....MY PRAYERS HAVE BEEN ANSWERED!!!!
LORD HAVE MERCY....WOW
3/4” pushrod lol
That’s insane!!!!
Awesome. Subd
Such a fantastic video! This is the first time I've ever commented on a video in the 6-7yrs that I've been watching videos on RUclips as my only source of entertainment. Thank you for the amazing content, excited for more to come! 🤘🏻🔥
Great content, expertly communicated. What the video doesn't capture though, is the SOUND that comes off an engine on the spintron. I used to run cup car engines back in the late 2000s; both on the dyno and the spintron. Past ~8000rpm or so, you couldn't hear the difference between an engine actually running and one just spinning with no rods, pistons, sucking, squishing, banging or blowing....just a bare "crankshaft" spinning a cam actuating the valvetrain.
Wow, incredible man. Congratulations on that.
That's amazing. Thanks for sharing with us.
WOW ! ! ! I learned more in this video in 20 to 30 minutes than that of the past 100 hours of other videos. I really enjoyed the intricate verbal details of stuff that is likely just common sense and common knowledge for all you folks, but was mind blowing for me. Thank you. Really neat stuff.
Comp cams and Jesel are unbelievable products
Glad to see you guys back.
Amazing job here. I loved it.
Super interesting! and such detailed r&d! These videos always confirm to me why the USofA as engineers doing amazing work. Awesome!👍👍
3/4" push rods! 😂 that is just insane. Seriously, great knowledge overall, thanks for sharing
hi just found you guys.....what an amazing video , so much knowledge such great engine building research and developement . a gearhead`s dream
I liked this video, lots of information, definitely not a super stock mindset. Those are now the biggest diameter pushrods I`ve ever seen, Ive been inside a Proline motor and they were 11/16, I couldn`t believe my eyes, at least now I know why
Awesome video, the results speak for themselves, the money and time spent on the Spintron was worth it 💯 definitely excited to see how fast the Sorceress will go now that parts stop breaking 💪
What an awesome look at what it takes to hold an engine together at this level. Thanks, y'all
Great video! One of my favorite cars. Sporting a Tom Bailey shirt I see! Super cool
Would be nice if you could see the spintron data with full cylinder pressure to see the exhaust valve open under all that force.
Yes, that must alter the data significantly
Such a good informative video!!! Thank you!
incredible engineering, just awesome
Very , very interesting ! Many thanks.
Extremely interesting tech here, makes me wonder what the engineers struggled with on the 4.900 bore space engines years ago. Really enjoyed learning about the cam cores you’re working with. Reminded me of reading Bill Jenkins telling about having 86 degrees of camshaft twist at 180 degrees of crank rotation but 94 degrees of cam rotation on the next 180 degrees of crank rotation. He also spoke about having ignition timing being all over the place from the front of the engine to the back from camshaft wrap up and unloading. Absolutely awesome that people are still finding ways to work around some of the same problems.
Thought it was pretty neat to see your one piece rocker stands. A set to fit the Brodix PB 2002 heads is one of my next planned purchases. My 4.610 bore pistons seem monstrous to me, I have a feeling the slugs in this engine dwarf mine by a long shot. Looking forward to seeing how their race tactics and program change with the new developments.
Crazy knowledge, 👍 subscribed ❤
There was a time, not that long ago, where 8K to 10K RPM V-8 engines were just not possible, or took a ton of cash, time & work to sort. It's amazing how technologies keep improving. Makes you wonder if there will be cylinder heads developed that will support 15K RPM on a big inch engine?
Certainly glad I stayed till the end. Kudos to all involved and for sharing hard earned info !!!
Excellent informative video!
WoW!!!
A step above.
Well narrated.
So cool hearing an engine run with no combustion
This is an excellent video.
Never seen an engine on a spintron before so that was interesting. Looking forward to seeing the car on the hub dyno.
Awesome stuff, I'm a junkie for this stuff. Really neat sensors for measuring combustion pressure. Looking forward to seeing the data from that. Y'all take care.
Awesome 👍
Such a great video.
What a great video i hope there will be more 👍🏿
Great vid bud very educational
To get that right combination it takes a lot of time and work man and some money
Wow!!!! So much info, such a great guy!!!!!!!!!!!!!!!!
Spintron technology is an amazing system for building engins
Indy car engines still use conventional valve components but made of incredibly light weight and still spin to 16,5k rpm. But it’s apples and oranges because of eliminating pushrods, etc.
Great video
Just move the exhaust opening back a few degree's, work on the exhuast port and valve seat. It'll probably pickup power opening later anyway
I only know what i been told or remember hopefully right . I think i remember this engine having problems with valve train problems..i remember Darrin Morgan talking about certain engine combinations having to open valves under a lot of pressure and at that time i wonder if this was part of the problem was . I remember Reir Morrison talking about how that really helped develop cam profiles and keep the parts from i assume going into a resonant vibration.. Stiffing up the rocker stand is a great idea ..Enjoy the videos
Very cool ! except there is no combustion boost pressure on the engine Tons of R&D Good luck guys!!!
nice work!
Would be awesome to see an SMX on the spintronic.
Seeing the cylinder pressure on the track will also be bad ass.
This shows just how good the SMX platform really is.
Super interesting !
What an educational video ! Well explained. I come from stock cars (retired & still NO expert,lol) and i've never watched a spintron test before. A couple of questions...Does the extra weight of those massive new pushrods & the really thick cam not affect power/throttle response ? Also, you mentioned the tremendous combustion pressures. Someone long ago told me that combustion pressure is always less than static, not true ? Lastly, is there ever a need to do spintron test with sparkplugs installed and intake ports uncovered ? Thanks
Holy shit you guys are absolute engine gods… I just have a couple questions one have you thought about going to an electronic valve assembly? Two have you thought about using something like a Ruperts drop for the tip of the pushrods and three have you taken into account being stuck on the two-step for a lot longer than what is anticipated
awesome
Great video… can you measure all the same thing’s with the engine running with boost? Would that effect things?
That would be one sweet air compressor
Now I would like to see this engine on the engine dyno so we know how much horsepower it makes to the crankshaft
Hi new subscriber here 😎
Impressive!
Could you please do a video on lobe separation and making power and torque with the right setup for what you want great video thanks for sharing
And one more question have you ever had issues in engines that run methanol that sometimes surface rust gets on the valve spring and then they break
Fascinating testing and validation. Thanks for sharing. I have a few questions
1) In this test setup (my apologies if you said) is it just the valve train (cam, push rods, valves, springs, oil) without the piston assembly (crank, conn-rods, pistons, rings)?
2) How does this valve train compare to that of a NASCAR motor that sustains that level of RPM for hours?
Great, great information. This channel and Steve Morris Engines are simply the best!
Back when I did cup car valvetrain kinematics R&D with GM, we cut windows through the block, into the cylinders so our laser system could bounce off a mirror and beam upwards towards the valves; thus measuring their position over time. The "crankshaft" was just a drilled bar to connect to the spintron, oil the main bearings and drive the cam. No rods or pistons.
I'm interested to hear what the valvetrain differences are between one of these pro-mods and the cup cars. Back when I was working on cup cars, 9500rpm was a maximum - but none of the valvetrain parts were as big or beefy as what I see here. Of course, a 640" engine has much more massive valves - so they're a lot harder to control. But then again, the cup car has to do the job a lot longer. We used to say MIS or Texas were the hardest on valvetrains because the way the cars were geared for those tracks.
Friggin military grade!
Military Grade $$$ !!
wow wow so cool thank you wow
Hi guys, pretty interesting stuff, I do not understand how the intake port are tape close when you do a pull. Cheers
What they do is they very carefully have high quality masking tape cnc laser cut to the rectangular block shape. They then program a Kuka welding robot to carefully and precisely apply the masking tape, using a special rolling attachment. There's another video on that.
Respect
YOUR’E MY HERO!!!!
VERY GOOD VIDEO THOUGH
It sounds like something Freddy scriba would name it
ExpertlyExplainedEngineEngineering
That setup is cool. I do have a question, does a running motor with its pressures and harmonics change the data? Very cool work. Super impressive..
