The air has to go through a single valve. Get a steel wheel and drill holes for 100 valve cores and try again with single line and single valve per pump.
@@theo_7212 You can have a line long enough the same way they did here, just withing joining them into a single line. Is it really that hard for you to think it through 😂
For a higher resultant pressure, all 100 pumps must be operated synchronized. What happened here was you reached a maximum possible pressure which could be sustained in the weakest of the pumps. Any further work was simply wasted in shifting air around the different pumps, nothing was directed into the tyre. Even with synchronized pumping, you would likely not have reached a much higher pressure, as one of the pumps inevitably would fail and leak. Great video! Haven't seen anything like it since Pumping Iron...
Appears all 100 pumps are in parallel on a single line. Split the hose with multiple Y connectors close to the valve stem into multiple lines say 10 pumps per line. Same amount of hose with a shorter air path for 90% of the pumps and less over all resistance. The pumps should be easier to depress and you should get a hell of a lot more air in the tire. I'm STONEDay and could be wrong...so hopefully the internet will like/upvote so Garage54 sees this comment. Happy new year all!
The pumps are hooked up on a series, not parallel. What is needed is to design and build special blocks milled on a cnc to combine many lines into one, with one way valves to prevent backflow. And then a pressurized tank (like in a regular motorized compressor) to collect and feed air into the tire.
The pumps contain check valves so really only need a manifold to get them in parallel. The problem is both volume and drag on the inside of the tube. Shortening and fattening the path will correct this, but not too far... If it's done right it'll be left with about the same loss as the current series layout in the video in terms of volume to "precharge" to get to a specific pressure. A 4" dia, ~4 ft long section of modest wall black iron comes to mind for the pressures any car tire could withstand, would flow much better. Pumps into individual ports on the pipe, extend tubes only as much as needed, and then the single tube to the tire just as if it were a normal air compressor. And FFS put the gauge on the line right next to the tire, and another one on its own port on the pipe. When they're equal, "you're as there as you're gonna be for now" They'd be able to drop the pumps normally for any given pressure and be done with the pumping part in a few seconds, leave the cylinder to equalize with the tire for a minute and call it 👍
Definitely the hose is a factor. More hose, more volume. The pressure will stretch all that hose enough to throw the results way off. Great experiment, I'd sure love to do any of the things you guys in Garage 54 do!!!
I had a flat tire in my car one time. With my bike and air pump, and no spare tire, I pumped up my tire with the bicycle air pump. It took a while, but it worked.
Bike tires are usually higher pressure than car, so it’s the sheer volume that makes the work, but it’s clearly not beyond the pump’s ability. (Nowadays it would be beyond mine.)
Do the independent brakes - 4 master cylinders connected to a joystick in an X layout and the master cylinders separately connected each to a respective wheel. Drive, and use the joystick to activate each brake independently to steer. (or use 4 brake pedals?) Also, hook up the throttle to the steering wheel.

@@Swansen03 UA-cam has not been de-monitising any channels because of this. Quit with the baseless batshit theories already. Prove it or GTFO back to the fringe bunker.
The individual pump plunger has it's limits on creating positive pressure. And when you daisy chain all those pumps it creates a line pressure differential. The pumps closer to the outlet has to overcome the already multiplied pressure created from downstream. So the last guy downstream has to overcome all the built up pressure, that's why Yuri (I think that's your name) had the hardest time to push the pump. Also keep in mind, that the plunger in the pump has limits on holding pressure so some of them will be leaking when trying to pump. In order to do this experiment correctly, each pump needs a one way valve to help minimize losses since the plunger allows leaks to built up back pressure. Enough said buddy, this was an interesting experiment indeed! Thanks for posting!
This needs to be revisited and many of the great ideas in the comments need to be tried. Can't wait to see the follow up video Garage 54! Ya are pretty awesome.
It reminds me of the saying, "Having 1 guy unload a truck of bricks is inefficient. Having 1,000 guys unload a truck of bricks is also inefficient." XD
More pumps equals more pumping loss, and also i reckon some pulses of air are travelling into other pumps, maybe try with check valves ore one way valves in each line.
I think you need a one way valve per pump as the pressure from the first pump is “lost” by the second pump etc... Also have a central “block” where all Jose attachments connect to. The farthest pump (pipe length wise) would have to do more work to produce the same pressure as the closest (shortest pipe). Only my theory! Great videos none the less! Merry Christmas!
The length of the hoses does significantly increase the volume of air that needs to be pumped, but it shouldn't be too bad really. Any leaks in connections or pumps would pose the greatest pressure loss for the system. The last and the most important bit is the opening in the tyre valve itself, check out how much compressor pressure you need to pump that tire in what time, and you'll see that you're actually limited by how much air can go through that valve each second. Anyways, a really fun video as always!
@@carcrashcompilation9459 Kind of a low way to get views on your videos ... and they appear to be videos comprised of stolen clips that have been around forever on UA-cam
I think someone else said the exact same thing but the entire volume of air in the hose in the entire volume of air in the tire is what's soaking up most of your air input
Each pump hoses needs to have a one way value hooked up to the main air hose that is connected to the tire so the air cannot flow back or in the other pumps but forward into the tire. Start with the far back pump and pump working closer to the tire.
Good stuff guys. The right angles and the extra volume create inefficiencies, you will always lose a lot just through the angles. Try, a y angle for each hose, better still a y with a straight side, if that makes sense. Love it.
You need one way valves on the system and then a couple pumps to charge the system, then you have to pump in sequence so as not to over pressure the line itself. The losses are being created in air traveling in both directions in the system and then cfm of what the line and valves can handle

If you did the pumps in sequence last to 1st the pressure would be pushed down the line and not fighting the pump infront of it, also could you connect the handles with some iron bar and do say rows of 5 or a circle of 20?
The flexible nature of the rubber hose from the pump expands with pressure. More hoses, more pressure, more loss. Use a hard line & one-way check valves to get the best pressure to the tire, not to other pumps.
awsome stuff they should put non return valves before the the T pieces,thats why it was difficult to pump all at once,the pressure pushing back into the pump and they fighting it.
By putting the pumps in parallel you are effectively putting a bigger and bigger cylinder pump in reducing the macanical advantage each time you add one so it takes more pressure to push down on one part of it . Also with the thin tube it is getting pressure locked because it's using the same small space . Good job though and good fun 👍
I am surprised they did not pump it up better than it did with all 100 pumps I like this you tube channel some pretty cool stuff also it's amazing that one air compressor can exceed the work of all those people I expected better results but it was still fun and interesting to watch.
A T in the line before the tire could have a permanent gauge in situ. The early results were interesting and the effect of pumping sequence of ganged pumps was significant and somehow counter intuitive, as you said. That would be an interesting exploration.
@@MNDashcam Myth. That's not how it works. Coronavirus is suspended within moisture droplets which get trapped by masks. The virus isn't just floating free in the air. Molecules that you smell are much smaller anyway. Don't get your news from Facebook 😂.
The air is back pressured thru the other pumps. If there was multiple one way valves all thru system there would be less pressure loss. Especially one way valves right at the very end of the the last few pumps in the line system that might make a difference I'm thinking?
So many "you need check valves" posts. Learn how pumps work. They already have check valves built in. Two of them, actually. One opens to allow fresh air in when pulling up and closed on the down stroke, the other opens on the down stroke to allow air out the hose and closes on the up stroke to prevent pressurized air from flowing back. The losses seen make some sense given the amount of hose, and the fact it appears to be fuel line and not a pressure rated hose. The pressure will equalize throughout the entire system, meaning if the tire is at 10 PSI, the air in all that tubing is also at 10 PSI. I did the math and it doesn't account for everything, but does account for most of the losses if you factor in some 'stretch' for the tubing under pressure. Given the amount of tubing, lets say (looks like 24 inches of tube from each pump to the 'main line' and about 24 inches between each pump, conservatively guessing, so...) 400 feet of 1/4" ID tubing, and ignoring the fact that fuel line isn't pressure rated and will expand, it's still about 240 cubic inches (about 4 liters) of volume in those tubes. I don't know the exact volume of the tire in question, but it looks like a 15 inch rim and about 3 inches of rubber so a rough estimate is a volume of about 1000 ci (16 liters). So with the math done, the tubing holds about 1/4 of the air in the entire system, likely more like 1/3 when the stretch from the pressure is accounted for. Add another margin for leaks in the system ans a chunk more for the fact that these sort of pumps will lose air if not pushed straight down, which the one pump per hand method is really bad at, and it accounts for most of the losses seen, with only about half of the air pumped ending up in the tire.
Can someone answer me a question? Here it is. The atmosphere psi is about 14.7 right? So do how tires deflate below that? Let's say if we deflate a tire opening the valve it will only deflate tô about 14.7 psi is that right? If that's it so why the tires sometime deflate below that?
I can't see if the pimps are connected in series or parallel, but the main problem I see is the main line is the same diameter than the individual pump's tube; so the pressure is leaking or inflating the main line that goes to the tyre, that is why you still had pressure after removing the tube from the tyre. As someone said in another comment, connecting the pumps to a main steel tube and then the tube to the tyre would work better.
The only issue here is the small volume bicycle pump. And of course the low flow rate of the tiny valve at the tire. You can inflate car tires with bicyle pumps just fine... it just takes some effort. Take a high quality bicycle tire pump ( rated for track bikes ) not these cheap ones. Some are rated up to 14 bar. So with enough time ( and arms ) you can make your car tire explode off the rims.
I think it's because the hose is only wide enough to allow one pump's worth of air to flow through. When you pump multiple pumps at once, only one pump's worth of air can make it through. That's why when you pumped in an alternating fashion with two people, you were able to achieve similar pressure, but when you pumped with two people at once you weren't able to achieve that pressure. Also, if the connecting bits don't prevent backflow, then a pump closer to the wheel would simply pump air away from the wheel due to there being less resistance to the air in that direction.
The pump engineers (not me) call this problem "dead volume"..... This is the volume of air that is located in a space other than the target (in this case the tire). The amount of air that is in the pump body, before the check valve, will re-expand with the next stroke. The hose contains air at the same pressure as the tire - that loss could be eliminated with a valve in the tire 'chuck'. Reciprocating compressors are notoriously inefficient, most industrial high-output compressors are of a 'twin-screw' design with effectively zero dead volume and far higher energy efficiency.
I could just see someone being on the side of the road, with a flat and 20 people pumping one tire at once with 20 pumps. xD People in my area: "Whaaat? They're crazy."
Try using shop air to pressurize the hoses and test for leaks in water, then plug the end into something that will seal it with a gauge and see how many pumps it takes on one pump to start reading, then compare to a single pump hooked to a gauge, then give that many pumps before you start counting, and print numbers 1-100 on sticky notes, then give those numbers to 100 people and have them remember their number, then just call out as you count to 100, that gives you no line losses and 1 pump per pump and one at a time to avoid valve losses

@@MNDashcam Myth. That's not how it works. Coronavirus is suspended within moisture droplets which get trapped by masks. The virus isn't just floating free in the air. Molecules that you smell are much smaller anyway. Don't get your news from Facebook 😂.
The air is back pressured thru the other pumps. If there was multiple one way valves all thru system there would be less pressure loss. Especially one way valves right at the very end of the the last few pumps in the line system that might make a difference I'm thinking?
So many "you need check valves" posts. Learn how pumps work. They already have check valves built in. Two of them, actually. One opens to allow fresh air in when pulling up and closed on the down stroke, the other opens on the down stroke to allow air out the hose and closes on the up stroke to prevent pressurized air from flowing back.
The losses seen make some sense given the amount of hose, and the fact it appears to be fuel line and not a pressure rated hose. The pressure will equalize throughout the entire system, meaning if the tire is at 10 PSI, the air in all that tubing is also at 10 PSI. I did the math and it doesn't account for everything, but does account for most of the losses if you factor in some 'stretch' for the tubing under pressure. Given the amount of tubing, lets say (looks like 24 inches of tube from each pump to the 'main line' and about 24 inches between each pump, conservatively guessing, so...) 400 feet of 1/4" ID tubing, and ignoring the fact that fuel line isn't pressure rated and will expand, it's still about 240 cubic inches (about 4 liters) of volume in those tubes. I don't know the exact volume of the tire in question, but it looks like a 15 inch rim and about 3 inches of rubber so a rough estimate is a volume of about 1000 ci (16 liters). So with the math done, the tubing holds about 1/4 of the air in the entire system, likely more like 1/3 when the stretch from the pressure is accounted for. Add another margin for leaks in the system ans a chunk more for the fact that these sort of pumps will lose air if not pushed straight down, which the one pump per hand method is really bad at, and it accounts for most of the losses seen, with only about half of the air pumped ending up in the tire.
I enjoy seeing this teamwork
Hmm 50 guys all hand pumping in a room together, not a video you would normally find on UA-cam 😂😂
LOL
Sounded like the voice over guy was pumping air too at one point lol
Can someone answer me a question? Here it is. The atmosphere psi is about 14.7 right? So do how tires deflate below that? Let's say if we deflate a tire opening the valve it will only deflate tô about 14.7 psi is that right? If that's it so why the tires sometime deflate below that?
Tire go BRRRRRRR
Boom* no bbrrr...

Put a cap on the exhaust with an airline fitting and use the engine to inflate the tyre???:)
I wanna see that!
I think its already been done. I'm gonna check YT for the vid👍
Is that even safe for the engine?
@@jamesshamley6577 to a certain point!:)
then you get some water in the tire.
I can't see if the pimps are connected in series or parallel, but the main problem I see is the main line is the same diameter than the individual pump's tube; so the pressure is leaking or inflating the main line that goes to the tyre, that is why you still had pressure after removing the tube from the tyre. As someone said in another comment, connecting the pumps to a main steel tube and then the tube to the tyre would work better.
@Garage 54 I wish you guys had tried this with the valve core removed and an inline gauge to eliminate the massive restriction of a Schrader valve.
I was hoping they'd try running some air tools with everyone pumping like crazy
The only issue here is the small volume bicycle pump. And of course the low flow rate of the tiny valve at the tire. You can inflate car tires with bicyle pumps just fine... it just takes some effort. Take a high quality bicycle tire pump ( rated for track bikes ) not these cheap ones. Some are rated up to 14 bar. So with enough time ( and arms ) you can make your car tire explode off the rims.
I love this, just pure fun
I think it's because the hose is only wide enough to allow one pump's worth of air to flow through. When you pump multiple pumps at once, only one pump's worth of air can make it through. That's why when you pumped in an alternating fashion with two people, you were able to achieve similar pressure, but when you pumped with two people at once you weren't able to achieve that pressure. Also, if the connecting bits don't prevent backflow, then a pump closer to the wheel would simply pump air away from the wheel due to there being less resistance to the air in that direction.
*Car tire is a bit deflated * "YO IGOR CALL EVERYONE FROM THE TOWN"
This is how the pyramids were built! A lot of manpower!
The pump engineers (not me) call this problem "dead volume"..... This is the volume of air that is located in a space other than the target (in this case the tire). The amount of air that is in the pump body, before the check valve, will re-expand with the next stroke. The hose contains air at the same pressure as the tire - that loss could be eliminated with a valve in the tire 'chuck'. Reciprocating compressors are notoriously inefficient, most industrial high-output compressors are of a 'twin-screw' design with effectively zero dead volume and far higher energy efficiency.
I could just see someone being on the side of the road, with a flat and 20 people pumping one tire at once with 20 pumps. xD
People in my area: "Whaaat? They're crazy."
Next "Can you start and run a car without flywhell?"
I mean what are you trying to accomplish here? welding a clutch to something else (crank)? Running no clutch?
Try using shop air to pressurize the hoses and test for leaks in water, then plug the end into something that will seal it with a gauge and see how many pumps it takes on one pump to start reading, then compare to a single pump hooked to a gauge, then give that many pumps before you start counting, and print numbers 1-100 on sticky notes, then give those numbers to 100 people and have them remember their number, then just call out as you count to 100, that gives you no line losses and 1 pump per pump and one at a time to avoid valve losses
