[@bongosock]

That Monte Carlo is an absolute sensation! :)

[@Rrottweiler]

Bubbles form during cavitation. As the pressure in the pump increases, those bubbles collapse in the form of an implosion - equally as violent as an explosion. The implosion causes shockwaves to travel through the liquid and hit the impeller causing mechanical damage.

[@Hydrazine1000]

Almost there! At the trailing side of a blade you can get such an under pressure that it creates a little steam bubble. That's when the pressure is locally so low that the boiling point reaches the ambient water temperature and little steam bubbles form. When those bubbles collapse they _directly_ impinge on the trailing surface of a blade. That's what causes cavitation erosion. (It can also occur in, say, gear oil pumps. So it's not just in water, or on the low pressure side of blades. It can also happen where gear teeth in fluid separate.)

[@cmsracing]

Same thing that happens to ship propellers.

[@fawnn1644]

It happens in the coolant on the outside of an engines cylinder sleeves too

[@Rrottweiler]

@@Hydrazine1000 Few weeks ago did see video of SBC oilpump with clear cover. Damn there was alot of bubbles and cavitation.

[@AB-80X]

It's cavitation burns you're thinking of. The supersonic implosion of the bubbles erode the surface. Happens to propellers on powerboats sometimes as well.

[@JamesTK]

Extremely high temperature when that happens too

[@ben94cobra]

and also, the same basic physics behind ultrasonic cleaners

[@hkguitar1984]

The Mantis Shrimp utilizes the Cavitation/Implosion phenomena to unleash a deadly blow with its front appendages. The cavitation bubbles formed and then popped release a shockwave that can crack mollusks shells, break glass, and, apparently damage dynamometer torque absorber components.

[@JamesTK]

[@hkguitar1984]

[@TheScottib1]

Allan's Monte Carlo is one sweet ride with power to boot... 😊

[@michaelmcduff2263]

Cavitation will only occur in the absorber if not enough suction pressure (feed water pressure) is maintained on it. You must keep the water in a liquid state as you add HP (heat) to it. As the absorber temp rises the supply pressure needs to rise and stay above the boiling point of the fluid. The minimum flow required can be determined by...........HP x 5.5 divided by the Allowable Temp Rise of the fluid.

[@brandonreed70]

Didn't they say they had plumbed compressed air into the absorber? Bubble implosion associated with cavitation is typical of a poor suction condition resulting in vaporization, but the independent introduction of air could induce the same result once it reaches the high pressure zones of the absorber.

Steve is the type of guy you want working and building your shit. It doesn't matter what he's doing his brain is just churning data and info. Him hypothesizing with the dyno guy was fun to listen to. Crazy knowledge and you can tell he just loves to figure out and know exactly how each little thing works.

[@mmnootzenpoof]

cavitation bubbles can produce so much energy when they collapse that sometimes it emits flashes of light, called sonoluminescence, so of course it'll erode metals.

I recognize that guy from across the pond. Since I made the switch to Your Dyno, ive had zero issues from my dynocom dyno that was broke down more than it wasn't.

[@phreeradikill]

Just an observation from one tradesman to another. I've been working with PVC for over 25 years. The swept tee at the bottom of the pipe is meant for drainage applications where there is no water pressure. The glue sockets are halve the depth of a schedule 40 fitting meant for pressure. That is defiantly the weakest point of your setup. PVC glue is supper strong it's aloud to cure, but that Tee is not meant for pressure, the plastic isn't as thick. I'd keep an eye out for cracks.

We had that problem with water ring vacuum pumps. The end plates would get scalded from cavitation that by outgassing of the water that created bubbles that would cut into the end plates and rotors. We installed water vapor gas eliminators on the top of the end-plates, and it eliminated the problem. By allowing small amounts of air into the end-plates it passed the bubbles through and out the exhaust side of the pump.

Steve always on an adventure to improve everything!😄👍

[@michaelmcduff2263]

The brake is just a simple pump. It will only boil the water if there isn't enough pressure on the water to kept it in the fluid state. Nothing wrong with the water getting hot (very hot) if enough pressure is maintained on the fluid to keep it in a fluid state (no boiling) so long as the temp is within the limits of the absorber. Refer to a publication called 'Cameron Hydraulics' to understand the pressure / tempreture curve required to keep the water in a liquid state at any tempreture or pressure.

[@briananderson5284]

Awesome Thanks for sharing, love it can't wait to see more.

[@ericmiller4285]

Its hard to have a single dyno cover a huge power range. An eddy current large enough to absorb that kind of power would be huge, and it would have so much inertia start ups and shut downs would be brutal. And as you can see, a water brake designed to absorb several thousand horsepower, does not flow enough water to stay cool with engines that create "low" torque. You will know when the water in the absorber turns to steam... steam doesnt hold back any power... instant rev limiter. Also, bi-directional dynos are very commonplace in automotive engine development. First shift runs the engine on one side, second shift runs the engine on the other side... minimal downtime. Andddd, Alan's car is amazing!

[@user-sg5ws7zw5h]

Thats a beautiful Monte Carlo

[@stevenraymer6682]

Thanks Steve great content

[@Screwdriversteve1]

The pitting that Steve is talking about is when micro bubbles form on the vanes, and when they collapse they create an ultrasonic shockwave that hits the metal so hard it begins to erode

[@SNAKERADIOS]

Wow man that Monte Carlo is so bad arse!! Its one of my all time favorite Cars next to Camaro and Corvette C2 and C3

We call the dyno mule a master. It’s the good unit or control. I run and maintain a transmission dyno

[@LAENGRACING]

Love my your dyno stuff, works great on my 902 dyno, Question though, why not use the servo valve on the outlet side, after plumbing in adequate volume capacity, and put a variable static valve on the intake side to control the servo percentage on starting the sweep, at say 70-90%, thus keeping water pressure in the brake, and maybe keep the cavitation down a little. Just a thought. Jostien is a great guy, his customer service is second to none. Enjoy your channel, I don't know how you don't burn yourself out...lol!!

Big diesel engines have specific coolant to combat the "cavitation" that your explaining. It will actually erode the liners from the vibration and explosion inside the cylinder and create these bubbles.

I cannot wrap my head around how those seats can be race legal in something that fast and powerful. Just seems insane to me.

[@keefershotrodshop]

The seats have good headrests and, additionally, the foam pads on the funny car cage is a great method of helmet containment. He has proper harnesses in the car and also notice that the bottom of the seat is modified for a proper anti-submarine belt. It's actually a pretty nice setup that looks really nice visually and is probably a lot more comfortable/less fatiguing for street driving.

[@AB-80X]

@@keefershotrodshop The integrity of that seat was never meant to restrain someone in a racing harness. I have seen actual racing seats get torn apart in crashes. When that happens, you are no longer strapped in, and flop about. Additionally, there are no side bolstering on those seats, and a racing seat is not safe because it's soft, quite the opposite. It needs to keep you strapped in firmly. That is nearly impossible to do when you get strapped against something soft. That old headrest might not hold up in a crash either, so it might not support your head at all - crashing while wearing the additional weight of a helmet and nothing to support your head, that's bad. There's a reason why we use containment seats in our FIA approved GT3 and GTE race cars. This is a 200+ mph car, that governing body does not even demand a HANS. As a racing veteran, I cannot for the life of me understand how that is allowed.

[@danmyers9372]

@@AB-80X- At least this car actually has padding on the bars around the drivers head. I would say many, and perhaps most of the drag and drive cars with funny car cages do not have padding on those bars. Just imagine the drivers head were the car to get in an accident while the car is being driven on the street. And the driver is not wearing a helmet….

[@jagharingenyoutube]

@@danmyers9372 agreed, and thats why you need a padded containment seat so your head doesnt get a lot of speed/movement and hitting the cage in case of an accident

[@bcbloc02]

I have literature from the early 70s where Clayton recommended buying an absorber with dual inputs so in the future when engines got even more powerful you could add another absorber to handle the power. They are rated 2500ftlbs individual or 5000ft-lbs in tandem. They are awesome for steady state because they used closed water in the absorbers so the torque load can be held constant. They also use air pressure thru the vent to add dyno load as it is easier to do 1% increase in torque with air than trying to get an ounce or 2 of water into the brake

[@18_DriftBox]

I would try to experiment with ventilation pressure. Perhaps high air flow instead of ventilation creates cavitation and airing. I'm very interested in the end result. Steve, please make an episode in which you fix the problem

@@steveletson6616 TBH the yourdyno guys have been around for ages. Steve has used Yourdyno ( DAQ and valves for a long time on the big engines. This absorber is a brand new concept and is under going testing (what you see here). It is not yet a consumer product. I have no doubt it will progress to the same point the control valve has (one of the best available anywhere). This kind of gear isn't developed overnight and its also extremely cheap compared to other offerings, i think pricing (when i enquired for my own shop) was around 14k for a full conversion with a billet absorber (when released) compared to 30k plus for other manufacturers. For some perspective many US / Australian companies charge 20k just for the software.. .no hardware.
