It's pretty cool to see the little bit of older tech with the blow through carburators. Whoever engineered those carbs is a genius. So complicated.

[@randalljames1]

Not really that big of science product. Is all about making the carb think is lives under boost as well as supply fuel. Learn what it needs one piston at a time.... we did this in the 70's when no EFI was possible.. We also built mechanical fuel injection to work with turbos.. Is all a lot of fun when you peel open the float bowls and find floats smashed flat... It really is the most responsive and best way to go but it is fraught with headaches... EFI made it stupid simple.. What is sad is some of the "facts" being put out. A certain tuber promotes high compression pistons (not a good idea).. That water/methanol makes power (it is used to prevent detonation, not make hp) What I love about Steve is that he learns as he goes and is not bashful about being wrong.. I have wronged a lot of engine parts over the years but each busted part is a le$$on... :)

[@CGT80]

@@randalljames1 I have been taught that air or oxygen and fuel burn, but water does not burn. If a percentage of the flow going into the engine is water, then there is less space for what makes that explosion and power. As a person with an open mind, the only way water would help is if the loss of that fuel mix volume cooled so much that the engine could make more power than what the lost air/fuel mix would account for. I'm guessing it isn't going to happen and it is better to control the heat through other methods such as not making excess heat in the first place.

[@joelg6740]

The thing is water turns to steam at 1600x original volume ​@@CGT80

[@CGT80]

@@joelg6740 Yes, I forgot about that, but have experience with it. water plus lead=tinsel fairy. It is fine when it hits the surface of molten lead, but let it go under and it blows. So, does the steam help make more power or is it purely just cooling?

[@bigbearvenom6145]

You lose power even though the water turns to vapor extracting heat it still doesn't have the expansion energy as fuel so it drops in power because of sharing displacement with fuel, and air, but it keep parts down lower in temps from reaching critical melt temperatures so you can spin engines to higher RPM where you can make exponential more power where boost fixes everything. Power.

[@theatomproject007]

Just a little Joule - Thomson action going on there. Whenever you have a gas mixture go from one chamber of high temperature and pressure to another chamber of lower temperature and/or pressure, there will be adiabatic expansion causing condensation. This is just a case of a gas mixture going from a chamber of about 44psi @ ~100degF to a chamber of about 14psi @ 70degF. The change in pressure alone caused all of the water molecules in the gas mixture to condensate. This is actually a common process in most hvac systems. Putting a blow off valve on the cold side of the intercooler will also cause this type of behavior and it's even more of an issue as relative humidity increases.

[@wobblysauce]

Yep. Some good pressure differential right there.

[@stevelacker358]

Correct… if you took the air in that dyno room and used a compressor to put it in a tank at 30 PSI, let it cool a little to remove some of the heat from compression (simulating the intercooler), and then suddenly vented it to atmospheric pressure, it would instantly cool far below room temperature and any remaining vapor in the compressed air would turn to mist.

[@slaith77]

I do work with gas and liquid analysis for chemical plants and refineries and have to take the Joules-Thompson effect into account all the time. Especially with analytics that have components that either boil or condensate depending on it's state What's also pretty cool is that almost all gases go cooler as the flash from the drop in pressure. Except Helium and Hydrogen, they actual increase pressure. Which can actually lead to hydrogen fires in plants that uses that under high pressure and get leaks. What's dangerous is that Hydrogen burns without a visible flame too But seeing the effect of the pressure flashing like in the video is really cool. There are also so many interesting discussions about how quickle temperature drops in a gas, because of how badly it transfers heat. I really liked your explanation 🙂

Fun fact: water expands 1,600 times its volume when it flashes to steam. 1 liter of water makes 1,600 liters of steam.

[@IronWolf_the_1st]

And that is why the yellowstone geyser exploded not too long ago, steam explosion

[@scottwheeler2494]

Every time it blows (geysers) its a steam expansion / explosion. When it draws in extra water it flashes extra large with potentially disastrous results. A few gallons more I suspect is all it takes. Happens every few years they report. It is really too dangerous to allow people that close.

[@kleetus92]

Cold air moisture, but you're also getting a bunch of instantaneous pressure drop which also lowers the temperature which basically makes a cloud. It's like cracking the cap on a 2 liter of pop when it's hot out, if you crack it just right it dumps the pressure, but you'll see a little grey cloud in there swirling around for a few seconds until it warms back up. Here you had a couple hundred liters of pressurized moist air rapidly cooling down. PV=nRT works!

[@greggiverson7606]

compressed air always has lots of water in it. The water doesn't compress with the air and settles in the tubing. That is why you must drain the air tank on an air compressor regularly, especially in high-humidity climates.

[@scottlagasse3182]

Dew Point. The temperature when the moisture in the air condenses. Droplets on the outside of a cold can on a warm day. When the charge tube blew off, is what it would look like in an AC system when the high side goes through an orifice tube to low side. We saw the mist due to a rapid drop in pressure. The air would have been colder than ambient air temperature in the room.

[@jeremymyers5643]

Yep, rapid pressure loss.

Thank you for going through this! I had always wondered how carburetor setups for forced induction worked, seeing it explained by you it makes sense with your comparison to a boost referenced fuel pressure regulator.

[@peternewman958]

STEVE as usual another great video mate. There are so many younger people who only have experience with EFI, they never grew up with or learnt the intricacies of carburettors and how they wrok with vacuum and airflow through tiny passages. Back in the 70-80s I had a 4cyl with twin DCOE Webers and that was as close to fuel injection as you could get for the street, of course we had mechanical injection for race cars. But nothing EFI, my first experience with that was CFI on Ford Falcons here in Australia, and you also had the Bendix injection from Europe. Keep up the great work and hopefully we will soon see the exit of the Right Royal PITA Hemi.

The simplicity of carburetors is just so darned elegant. All that control with no external power, just direct the pressure differentials to the right places, through the right restrictions (jets) and applied against the correct springs… and it WORKS. No matter how much I like EFI, I’ll always have at least a couple of good old carbureted vehicles around.

[@jesseshort8]

[@anomamos9095]

Tip There’s an issue with some Holley type carbs that if you’re unaware of can drive you nuts. The issue is that after a time of use the gaskets in the metering blocks swell into the channels partially blocking them off. It can also be intermittent and or progressive depending on throttle position. A temporary solution is to shave the gasket in the channel areas thinning it out so it causes less restriction. Using two gaskets with shim stock between and completely cutting out the channel area on one is a more permanent solution.

[@throttlebottle5906]

I don't think it's as bad an issue or maybe not at all with the blue reusable gaskets. now the other gasket type do all sorts of bad things, especially if allowed to sit dry of fuel. I have seen the cork and other composite type completely pulled in over passage holes, crossed passages or even so far the bowl was not sealed at all anymore. old power valves so stiff they don't work hardly or stick open/closed and of course the accelerator pump diaphragm. old enough to have learned and rebuilt piles and piles of carburetors and you know how that works, rebuild a few then everyone, their brothers, sisters and neighbors come running with them. distributors, points and all ignition types too, lets give alternators/generators a mention also. 😑

[@anomamos9095]

@@throttlebottle5906 I haven’t touched a carby in so long the last one now has grand kiddies, so improved gasket technology should have come along long ago. I vaguely remember there being a rubberised aluminium gasket similar to an LS oil pan gasket being developed to counter the issue I described but that was long after I gave up on carbureted vehicles

[@bds598]

The rapid change in pressure also causes an instantaneous temperature drop. If it went from 30 psi of boost (44.7 psi absolute, psia) to atmospheric pressure, 14.7 psia, that's a pretty big drop over a very short period of time. Think of an orifice tube or expansion valve in an AC system. The tube upstream of the orifice is usually warm, and immediately after it's cold to the touch (and sweating if it's humid outside).

[@michaelloth5870]

Steve, Compressing air forces water to condense out of the air. That is why we have to drain our air compressor tanks. I think your ice water inter cooler was a big part of it and the boost level contributed to it also (water in the tube). I'm sure it is as humid in MI as it is in WI this time of year.

I had a Spearco air to water on my supra in the mid 90's that started doing the same thing. The intercooler core had a leak. The plugs are getting steam cleaned. It would suck water into the intercooler at idle then as boost came on it would blow into intake stumbling until it cleared up. I had an old Accell DFI pro sequential on it that I bought from Lawrence Conley who had it on Tweeked his buick grand national. Fun times!

The intercooler dropped the air temp below the dew point of the water. Also, the inlet tube coming off allowed a drop in air pressure to near atmospheric which also causes a big drop in temp - like what an expansion valve in an air conditioner.

Condensation yes but could also be the manifold backdrafting through the carb and pulling more fuel out. Carbs work in reverse.

[@gordowg1wg145]

Cool. I don't know if it's relevant with the US carbies, but there were some cabs with thin-walled brass floats, and they would collapse with even mild boost, causing the float's needle valves to fully open and flood the engine. With the float design used there, some would paint then with a fuel resistant varnish, as some would otherwise absorb fuel under boost pressures, which also caused the engines to run rich.

[@bigskunk801]

I remember a 7th grade science lesson on air. When compressed air is suddenly released the moisture in it will condense into a cloud. That’s why you need a water filter on all air compressors, especially when using it on a paint gun.

[@bo-dine7971]

Correct me if I'm wrong but the condensation explosion is because the room-temperature-ish compressed charge escapes & rapidly loses pressure, due to ideal gas law this means that the charge's temperature must also rapidly drop and so the de-pressurized charge is actually colder not only than the surroundings but also the intercooler, that's why the amount of water is so high and since it's on a molecular level the condensation is insanely fast.-forming. For those who don't know Ideal gas law basically states that for a given amount of change in gas pressure there is a linear change in gas temperature, that's why any kind of forced induction greatly increases the temperature of the charge and the higher boost the higher the change, that is also what happens in the cylinder & why compression-ignition works so well.

[@geniferteal4178]

The floats work just like the toilet bowl😊

[@finnroen2334]

Good info and fantastic vibe / atmosphere in this video.

[@trevorjlewis]

what is interesting is that with the boosted air under pressure that moisture would never be seen, just the rapid expansion of the hose blowing off is what condensated the moisture out. There is a few BHP in that moisture too. If you were to feed air from a dry air source or say sealed then filled that dyno room with dried air do you think you would see less horsepower?

[@K-Effect]

When air gets pressurized the water molecules in the air get closer together and that’s why you see “water vapor” when the charge pipe decided it didn’t want to play anymore. You’ll see the same water vapor when a truck tire explodes

[@ToolinAround2025]

I want to say that since this forced induction engine, the cooling effect of the water condenses the air charge such that there is more O2 with the water. Assuming there’s not more water than can be vaporized by the heat. That water was vapor until it hit the atmospheric pressure and turned to liquid water.
