No such thing as luck at your level. Thanks for taking us along.

10,000 rpm and 640ci of pro mod pure awesomeness! Every enthusiasts appreciates this more than you can imagine.

Valve stem deflection is far more that I would of thought thanks for this

That you share this tech with us is SOOO appreciated!! Setup the experiment, collect the data, analyze it, and only then make changes -- science. Thank you!

Real data! I love the instrumentation on this and other videos. You presentation is easily understandable by most of us who really care to learn. Thanks far taking the madness away from racing valve trains.

Six hundred fourty cubes spinning at ten grand. My god man,that's amazing. And that needed to be spelled out for emphasis.

You guys are Freaking awesome. I'm an aero engineer and watching all of this is truly fascinating, really makes me wanna switch fields and work alongside you guys, Definitely keep it up!!!!

I wish we would have had this kind of info back in the late 80's when I was running a blown alky 426. This is cool info. :)

Thank you for the free education, for a guy like me this is GOLD!!!

Actually Tom Bailey owns America’s fastest street car Verified 5.99 during hot rod drag week, And a few 5.60’s during testing

Great info. Crazy the valve springs harmonics almost knocked the lash cap off

Congratz on the improvements.

The improvements made weren’t cheap but is absolutely worth it when you factor in reliability in not having to replace parts after every run. I believe this would be absolutely a winner at endurance racing like Le Mans.

Good stuff. I was following along when Ben was working on the Spinal Tap stuff, and I got a lot from it and to see more on the subject is cool. Best of luck to you and Ben. Oh, and to The Cam Whisperer,,, Billy Godbold,,, lol.

INCREDIBLE!! Pragmatic expertise proving out at it's highest level... 💎

Very interesting and informative ! Thanks for that. PS: love to see this car at an event competing against others of this caliber.

This is the gear head stuff I can nerd out on all day!

Many years ago the company I worked for sent me to a class that taught us about vibration and frequently of equipment. How things can go into a resonant frequency, how to use equipment to measure and plan maintenance based on those readings . I remember years ago a company how they used a large electric motor to spin up there engine to see how or what was going on with the valve train . I thought you had valve train problems and that your using a spin tron to solve those problems makes a lot of since . I been told that the oil helps cool the valve springs . Being able to spin up the engine and have it reliable seems to be a winning process. I don't know anything about building the engine you have but I was told that some of the very high rpm engines have loft designed into the valve train . Good luck with your engine

Great stuff man

I still think people are waiting for Sorceress to go on Drag Week

Thats incredible!

I love this monster!!!! It sings beautiful music!!!!

Rod your passion as an owner is beyond impressive!! Thank you and Ben one of the top three of most informative videos I’ve ever watched!! With the new spring how far off of coil bind are you??

That at 2:25 must be one of the coolest knowledge enhancing slow motion clips for me I've ever come across!

Love to see and hear the power when you fire 🔥 it up

yo the spintron is a beast

This is BadAss!

Those oil squirts coming from bottom springcollar really shows how the collar comes off the surface and pumps oil to a squirt.

Amazing!

Now that was brilliant viewing…

Hell yeah guys, Well done Ben Love the Emtron controlling the rpm curve too

Get video of the lifter and pushrod. They are the true culprit of valve float.

Violent is an understatement. That explains the wear on the locks.

Be cool to see this with a behive spring also

That's awesome content! Better understanding about Spring Frequency. Do you think there is much of a different if the engine is fired up, with cylinderpreassure and different Frequencies during the combustion?

About 30yrs ago I was laying block inside of crane cams and heard a dyno making runs, I expressed my interest in it to one of the crane guys and he said he`d walk me down there, It wasn`t a dyno it was a spintron. The noise was really loud, all valve train noise. I believe thats the noise you hear in the in car cameras and not the exhaust sound. They had 3 of them and a Harley one too along with dozens of blocks. I guess comp cams owns them now cause they been gone a long time now

Done any drag n drive events.? . . . Not a street car unless it does

That sounded so smooth at 9 grand it's scary

Whats going on at the spring and retainer is not much more dramatic than DOHC at the same RPM and i was surprised how stable the rockers were.

Awesome, so i I have to ask , what will the heat do for it ?

Wow!

Ben Strader is the man.

Every time he says "RPM's" I wanna gouge my eyes out

Im assuming this is a solid roller set-up, but what's your clearance to coil bind?

How do you account for combustion pressure on the exhaust valve?

Winner winner chicken dinner 😀

I love how much technical detail you're sharing, that's uncommon. I have no idea how you don't have dozens of times as many subs as you have... spinning a streetable mountain motor to 10k is insane

My question is what is the effect when boosted?

I know this is a different topic but I believe you will understand and can clarify this for me.I still have a hard time understanding the actual difference between what Measurement of Force HorsePower defines as opposed to What Torque defines. If I were to look at it as HP is the Highest Force reached and Torque is a calculation to do with at what RPM it reaches that Maximum Force, is that how it is calculated? Another way of asking for clarity would be, lets say a Motor has 1000 HP and 800ft.lbs. of Torque. I want the HP to stay the same. What component and/or characteristic do I change to alter just the Torque. What exactly is measured to determine torque? They are both just words given to Identify a particular Force rating. The word HorsePower has a logical reason for the use of that term. Torque confuses me. Way back in 1979 in Auto Class, We were told that the amount of weight and/or load 1 horse could move a certain distance on a loadable/repeatable jig equals 1 HP, did the calculations really start from that method? This R&D with that spinning device shows many things we would never see or understand are happening under all that load. This is ingenuity at its finest. I venture to say what you are doing here is groundbreaking as far as Supertuning. The old rule of thumb is the last 50-100 HP costs as much as where you are now. You are leapfrogging that theory. 2000 or more RPM over the industry standard is something never before seen in this category of engine. The fact that you the Owner and the tuner, are willing to let us see what you have discovered really speaks volumes about your character. Unbelievable video, catching that keeper coming out of socket saved you at least 1 blown engine.

Didn’t Frankenstein engine development do 10k with a 900hp na ls ?

why can't you create a cam with multiple different lobes for spintron data? with a clear rocker cover you'd be able to see the characteristics of multiple lobes in one cam instead of making multiple cams is that possible?

What engine is it based off of ? V8 V10 V12 ?

Are you guys going to eventually offer camshaft and valve train packages that have been tested and verified?

I can only guess how much you can't wait to put her together, and let her eat !!! Because, I'm like a crazy ass horse on crack blazing at the bit, to see her run ! hahahaha

Very cool . You're the Sheldon of the motor guru's. Lol

So my question is what happens when you add 60 psi of boost to the intake valve.Does the boost on the back side of a 2.600 valve effect control.

When is this car going to compete at a drive and drag event ?

I use 350 seat pressure springs on my big block Chevy 565

This is why you should get your car serviced!!!! Mechanics always put this level of care to your car!!!

😎👍🇺🇸

I just want a good 350 to rev this high. Ok maybe a 397!!

So, as a guy who can only afford to build $6K-ish race engines, and if you're already having issues at 6500rpm with valvetrain becoming unstable, I wonder what all is going on in my engine and it's valvetrain that could be better? A more stable valvetrain has to equate to more horsepower and a longer lasting engine! Without all of this incredibly high priced equipment, I wonder how a guy might be able to figure this stuff out about his own engines?

What are bore/stroke? 640 is pretty tiny for a 5.3 bore spacing, obviously TT rather than nitrous but since 900+ is common for nitrous I'd have expected at least well into the 700 range.

Luck = preparation, opportunity and execution

I’m here for all the pushrod haters whom say you can’t spin them!

It's a street car, not a streetcar, BTW.

The engine running under its own power will fly apart.

Do what Tom Bailey does, then you’ll have something to talk about. Tom is decades ahead of you.

Where's the headers?

Lol. Ls is the only thing that runs that good .. 😁😁😁😁 Sarcasm at it's finest

" They're the only things that run that good. " you lost me on that one. Worthless biased statement.

"Street Car" has been a diluted term for quite some time..........

“Street” engine’s don’t rev to 10k rpm unless they are routinely tore down every week depending on mileage that week. Good clickbait for the ignorant tho

What you have done in a few days took a long journey of trial and error before the spintron. Thanks for sharing.

Does anyone else feel like this takes away from the magic did an engine builder/ racer/ everything that was magic about building a car and engine? We all wanna know why we were born and what our purpose is but when it comes to racing I think the dark is what use to make it the best part. Engine building will never be the same as it use to. It’s now $$$$$ not experience

" America's fastest street car engine " How fast has this gone, how many times has it backed it up, and in what sanctioned event? Are you saying this engine has driven to the track, and then been faster than 250 mph in the quarter mile, multiple times ?

Go 9600 and quit playing
