- Huge thank you to @EFI University for helping us improve the valvetrain on the Sorceress 640ci Pro Mod Engine! Also thank you to Billy Godbold and @comp for knocking us out two new cams to test out and allow us to spin the engine higher than ever before safely!
As soon as we get the new rocker stands from @JeselValvetrain we will be back with even more testing!

10,000 rpm and 640ci of pro mod pure awesomeness! Every enthusiasts appreciates this more than you can imagine.
Thank you sir! We appreciate it more than you know!
No such thing as luck at your level. Thanks for taking us along.
Ben we appreciate your support!
Thanks
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!
Six hundred fourty cubes spinning at ten grand.
My god man,that's amazing.
And that needed to be spelled out for emphasis.
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.
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!!!!
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
Tom has the quickest ET, but Sorceress is the fastest @260 mph.
Tom Bailey for the win
@Lord Commander
I stand corrected
Fastest and quickest are two very different things
Forgot bailey’s MPH, Mid 250’s would seem about right with that ET
This car doesn’t run coolant in the engine so I don’t know why they think they can call it a street car. It wouldn’t last one day on a drag and drive event. Bailey has the quickest and fastest street car period.
@@lordcommander3224
The problem is that Sorceress is not a street car. Drive that thing for 50+ miles and see how it fairs. It's a solid block engine.
Thank you for the free education, for a guy like me this is GOLD!!!
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.
Congratz on the improvements.
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. :)
Im sure you had more fun than the over the top tech , its racing, not a laboratory
Great info. Crazy the valve springs harmonics almost knocked the lash cap off
INCREDIBLE!! Pragmatic expertise proving out at it's highest level... 💎
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.
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
This is the gear head stuff I can nerd out on all day!
I love this monster!!!! It sings beautiful music!!!!
That at 2:25 must be one of the coolest knowledge enhancing slow motion clips for me I've ever come across!
Hell yeah guys,
Well done Ben
Love the Emtron controlling the rpm curve too
I still think people are waiting for Sorceress to go on Drag Week
It would never last. It’s a pro mod they drive on the street which is not a street car. No coolant/radiator means it’s a race car and they run a rich enough mixture for short street drives to not overheat.
It's not a drag 'n' drive car. Solid engine. Race car with plates.
drag 'n' drive cars have plates and drive hundreds of miles and then pull off a 6:40 time slip.don't claim to be the fastest street car if your not gonna back it up is all I'm saying@@AB-80X
Very interesting and informative ! Thanks for that. PS: love to see this car at an event competing against others of this caliber.
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??
Love the video and info but I would hate to cut a nice set of custom billet valve covers just to make this video ! lol I’m sure that wasn’t a cheap replacement , let alone have to weld them back up and keep using a beat up cover on such a nice engine .. would love to see this video on a turbo ls motor so some of us reg folks can see how much a street strip engine is effected with around .650” lift springs .
Love to see and hear the power when you fire 🔥 it up
The engine isn't running- spun by an electric motor.
I think the noise is just air moving through the engine, no combustion.
yo the spintron is a beast
Those oil squirts coming from bottom springcollar really shows how the collar comes off the surface and pumps oil to a squirt.
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?
I wondered the same thing.
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
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
@Daniel
It’s not streetable, There’s no coolant system
It would never survive Hot Rod drag week where you must drive 1200-1500 miles in a week
@@mrvwbob156 really? I've seen videos he posted driving on the street, maybe just very short distance but I thought it had coolant.
@@totensiebush
The engine is a solid block Proline mill. Not a street car. It can do super short drives, but no actual drives for many miles. Drag Week, Sick Week, RMRW etc. demands that you drive between 100-300 miles per day and about 800-1000 miles per week.
I like this car and I think it's impressive, but calling it a street car is definitely a stretch.
@@mrvwbob156
None of those events has ever been over 1000 miles.
@@AB-80X that makes it *far* less impressive... I had seen video of it on the Vegas Strip etc and assumed it was at least marginally streetable (maybe less than an SMX but in the same category)
Thats incredible!
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.
Done any drag n drive events.? . . . Not a street car unless it does
Violent is an understatement. That explains the wear on the locks.
Be cool to see this with a behive spring also
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.
What seems like a straightforward question is actual quite complex, even if the manifold air pressure (MAP accounts for atmospheric pressure also so 60 psi MAP is actually 60 - 14.7 = 45.3 psi boost) remains constant, the cylinder pressure is changing with RPM and that cylinder pressure is working against the face of the valve (whilst ever positive pressure exists) pressing the valve on the seat. Once the inlet valve opens the MAP may have an extremely minor impact at very low valve lift.
The a possible problem with this engine, and an issue PRO STOCK went through, is the cylinder pressure is still so high when the exhaust valve tries to open the cam lobe, lifter, pushrod and rocker keep coming but the cylinder pressure is holding the valve closed. This can be minor and only cause minor deflection in the pushrod or it can end up being broken rocker arm or the valve lofting ends up pulling the head off the valve destroying the engine.
Spintrons are great for testing the stability of the valve train and are a valuable piece of the puzzle, however, without cylinder pressure, running temperatures and the harmonics created from the rotating assembly, all other accessories and being mounted in the chassis they are not giving a 100% indication of what the running engines experiences.
Get video of the lifter and pushrod. They are the true culprit of valve float.
Now that was brilliant viewing…
That sounded so smooth at 9 grand it's scary
Ben Strader is the man.
Are you guys going to eventually offer camshaft and valve train packages that have been tested and verified?
Not sure if they ever read the comments.
That would be awesome.. most of us cannot afford to buy a bunch of different valve train components to test them on a spinatron.. so a package would be ideal..
This is BadAss!
Great stuff man
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?
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.
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
I promise in future videos, to only comment a couple words ! You gotta understand, that your badass videos make me feel like I'm right there with youz guyz, and feel the excitement you feel ! It's like watching a step niece, go from playing kickball in 3rd grade, to a world class soccer player ! I will probably piss in my Batman Underoos when I get to see her run ! lmao
How do you account for combustion pressure on the exhaust valve?
Amazing!
Every time he says "RPM's" I wanna gouge my eyes out
Awesome, so i I have to ask , what will the heat do for it ?
Didn’t Frankenstein engine development do 10k with a 900hp na ls ?
Im assuming this is a solid roller set-up, but what's your clearance to coil bind?
What engine is it based off of ? V8 V10 V12 ?
My question is what is the effect when boosted?
Wow!
This is why you should get your car serviced!!!! Mechanics always put this level of care to your car!!!
Winner winner chicken dinner 😀
Very cool . You're the Sheldon of the motor guru's. Lol
Do what Tom Bailey does, then you’ll have something to talk about. Tom is decades ahead of you.
Valve spring temperament time
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.
Making power when you have turbos is not the issue, reliability and longevity is.
I use 350 seat pressure springs on my big block Chevy 565
I had valve float before I went with the pack springs with an install height of 2.1 I had 350 seat pressure 1190 open pressure I spun that motor to 8600 all the way down the track from the starting line to the finish line for 12 years only thing I did was James spark plugs and oil so I don't understand why you're trying to reinvent the wheel you just need to get the right products for the job and you guys are expending tons of money to do that
And I didn't use tied on rocker arms like that I just had regular shaft rocker arms on a stud with a stud girdle on my 565 but I did alter one part of my 565 cuz I didn't like going faster than the sticker on my cage with allow so I opened up the orifice on the lifters change the spring in the lifters so if I run a 5:40 oil I never got full lift of my can the car would run a 9.06 ET at 154 mph
With my modified roller lifters
When I changed the oil to 2050 that's when the cam and the motor came to life
That's when I get told by the track officials that if I did the slow down I couldn't run the car anymore until I upgraded my roll cage so I went back to 5:40 oil and waited for the day some joker wanted to put money down saying his car was faster than mine I just changed the oil and collect the money
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?
Hate to say this, but if your valve train is getting unstable at 6500, you need to talk to someone else about your cam lobe choices and spring selection. I've spun a BBC to 8000 with 2.300 intake valves on hydraulic lifters.
$6500 engines are just as much fun as these dreamer over the top tech deals . If you can afford ti intake valves and a rev kit on top of your roller lifter you probably wont have valvetrain problems . I dont know why rev kits have become obsolete, i love em and run .700 lift on a pump gas sbc for 20 years and replace the springs every 3 years. Hundreds of runs . Im old , what do I know😅
Luck = preparation, opportunity and execution
I just want a good 350 to rev this high. Ok maybe a 397!!
I don't see why it wouldn't.
@@kensmechanicalaffair I have seen 7200, with a flat tappet hydraulic cam. Same engine runs 6500 flat out. But watching the valvetrain work better with less spring pressure has me thinking. I definitely want to look at shaft mounted rockers for a small block Chevy setup. I may even look at solid rollers for 8000rpm street operation. Back in the day small cubic inch engines were running to 7500rpms, with solid flat tappet cams. No reason with new stuff we should not be able to get the high rpm’s wind a good hydraulic roller or solid roller.
@@DavidB7474 I'm sure you have good flowing heads, and balanced internals. Should be a piece of cake.
9+k with solid rollers on an SBC is super easy.
@@kensmechanicalaffair circle track engines do this all the time with basically stock internals, good clearances, hyper pistons, flat tappet cams. Mine is nothing fancy: Cast pistons, stock rods, polished cast crank, it’s a mid 70’s .060 over, 4 bolt block, I’ve freshens this thing up three times. Clevite bearings, speed pro moly rings. Clearances are almost perfect, almost because it’s just a little to the loose side. Still in spec. Any stock internally balanced small block can handle rpm’s with the right attention to detail and the right valve train and valve springs. Now the 2.02/1.60 valve 882 heads with screw in studs and guide plates are ported to a 1206 gasket and I took out plenty of material. Guess they flow alright for this combo. It’s just a fun engine. If I build something with a good aftermarket rotating assembly, some big darts, and serious valve train, I would be dangerous. We shall see.
When is this car going to compete at a drive and drag event ?
Never. It's not a street car.
😎👍🇺🇸
I’m here for all the pushrod haters whom say you can’t spin them!
The engine running under its own power will fly apart.
It's a street car, not a streetcar, BTW.
" They're the only things that run that good. " you lost me on that one.
Worthless biased statement.
Where's the headers?
Lol. Ls is the only thing that runs that good ..
😁😁😁😁
Sarcasm at it's finest
"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
can your 4000 horse power car drive 2000 miles?
Sir, you can rev a Honda engine to 10k as much as you like, with a little bit of knowledge.
@@kensmechanicalaffair but then again, that Honda doesn't have 1" of lift at the valve ..LOL
Agree this is a click bait title, they have no business calling this car a street car. It’s not about the rpm’s. Motorcycles run over 10k rpm all day long. They don’t run coolant in the block and that’s the reason it’s not a street car.
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 ?
I've heard Bailey talk about it..... I personally haven't seen it in any drag and drive event.... That's interesting about the sanctioned event. Larson may actually be the fastest with the truck and that was 4 or 5 years ago at a NHRA event....
What you have done in a few days took a long journey of trial and error before the spintron. Thanks for sharing.
Go 9600 and quit playing
