That little sprayer also is only hitting a small part of the intercooler, multiple sprayers or the small misting garden hose works very well for wetting the whole intercooler.
Using the spray inside the pipe is even better, water droplets will enter the intake and the compression stroke will increase engine's thermal efficiency, while the water droplets absorb heat, and if they become steam, increase exhaust gas pressure, achieving top boost sooner
Another good idea and also on a budget is actually using one of the windshield sprayers which actually has a little motor that jet sprays just extend the hose and run it to your intercooler and spray just by pulling your wiper controls instead of pumping while you driving and come with own little water tank! :)
+shawn upole Windshield washers aren't required for inspection. At least not in Texas. Here you technically don't even need a windshield. If you have one, you need to be able to see through it though.
Even though this video was really short, I'm still so happy you guys made a video. Best subscription I've made on youtube is to you guys! Keep it up! And I'm looking forward to the s2k mods :D
petey2crazy Not aluminium. Definitely true for tempered steel, but mild steel/iron or aluminium is fine. This is why watercooling for brake discs (which get way hotter than intercoolers) is fed to the mild steel core of the disc and never the tempered friction surface.
Try a CO2 chilling system. Much colder than water & no issues with water that doesnt evaporate & then ends up under your tires. The liquid CO2 in the tank will turn to gas as it sprays therefore cooling much better & zero will drip onto the road.
I've got something you guys should test. It's an old trick that no one really does anymore. I don't know if it really works or not but always wondered. For N/A cars, people would re route the A/C compressor lines that have freon in it, you know, make up another line, and actually wrap that line around their fuel rail. Supposed to drastically decrease the temp of the fuel being injected into the cylinders. The reason I wonder if it really works, is if the change in fuel temp, actually makes it burn better. In theory it should work, maybe that would make a good mythbusting episode?
Brandon Camejo should lead to no measurable difference. fuel density does not change that much with temperature as air density does. The amount of fuel injected in comparision to air is extrem. Cold fuel has a higher viscosity, this will destroy your fuel injection system faster in the long run, as more work has to be done. (especially for diesel)
You could always rig this to a secondary tank with a pump that activates with a micro switch under the gas pedal that way it only turns on under high load.
They have an aftermarket ECU, with some tinkering there is probably a way to map the sprayers to engine load/manifold pressure/ambient temperature and have it automatic.
Several people are saying that Moog saying it's a 10% drop is wrong because when done in the Kelvin scale it works out to be a drop in temp from 313 to 309 (or something like that). I think only way you could measure the effectiveness would be in measuring change in temperature (or deltaTemp if you will!) from ambient. It'd have to be from ambient, because a basic air-to-air intercooler with no cooling spray or anything will not get the intake charge cooler than ambient. It's impossible. So, Moog says that the ambient temperature is about 30C. At 40C the change in temperature would be 10C, but the extra 4C drop from the spray brings it down to 6C. That would mean the intercooler would be 40% cooler! Let's look at the second set of readings. At 48C, the change in temp would be 18C. Spray the intercooler and get an 8C drop, to 40C, which is a roughly 45% drop! Not too bad! (Edited because I didn't realize they mention the ambient temp.)
that they achieved as much as they did with such a small setup (single nozzle) with relatively low water flow speaks to how well the concept works. If you have a multi nozzle setup triggered by boost it would be much more effective when needed.
I plan to spray paint mine black for 1) stealthier look 2) ur video proof of it helping with temps 3) fight chances of rust from doing a IC spray set up Marty was talking about with cars having 2 windshield washer pumps and using the rear one for IC spray instead. How much area is ur spray covering? For ur next test maybe add multiple sprayers covering more or all of the IC fins and see if that makes a significant difference. I plan to use old windshield washer sprayers I took from the junkyard and hook 2-4 of them up. See how that goes. DIY life :p
That's pretty good for something worth under $50. But my computer runs hotter than that on idle. No it's not broken, that's normal computer temps for someone on stock cooler. But still, I think it's time for an upgrade. Thermal compound must be burnt at this point.
My old 6970 used to idle at around 50 and would jump up to 85 when i was gaming. my new 290x runs nice and cool idling around 30 and only gets to about 45-50 when gaming.
U do understand that is the temperature of the air coming from the atmosphere to the turbo? Its not the same as the radiator stopping the engine from overheating which would be the equivalent of you comparing the temp of ur cpu on ur pc.
You said 4C drop from 40C is a 10% drop. That's not actually correct. Celsius is measured from 273C above absolute zero. So actually its a drop of 4C from 313Kelvin, as 1 Celsius is equal to 1Kelvin. That's 1.2% difference in actual temp lost from the system.
In the end it's about air density, which is inversely proportional to the T° in K at constant pressure (ideal gas law). Gain in density = (1/T1 - 1/T0) / (1/T0) = (T0 - T1) / T1 = 4 / 309 = 1.29% Almost the same as the drop in temperature for small variations.
What if you guys used a mister system with several heads to cover the entire intercooler. A mister system would cool the air before it hits the intercooler. I live in Arizona in the states so I know a bit about evaporative cooling. I can relate to you guys lol. Cool show by the way. Love watching it
Water is better; it has a higher specific heat than rubbing alcohol, so it takes more heat away. Rubbing alcohol will just evaporate faster; but water, especially at speed, on a hot intercooler, should be more effective.
Jesse Nicola Evaporation, yes. But alcohol will definitely have a negative effect. Alcohol evaporates easier; it requires less heat to evaporate; therefore, alcohol takes less heat away; that is how the evaporation cooling process works. Trust me, we did this in chem class with calorimeters. The heat capacity of the liquid (or fluid) and initial temperature (for overall temperature change of fluid, which when you multiply in Q=mcdeltat (deltat being change in temp. c being specific heat and m being mass) are what matter most. With alcohol and water, both at room temp (most likely, in a car), because the specific heat of alcohol is lower, you would need much more alcohol to match the cooling potential of water. No, sorry, a 50/50 or any mix is a bad idea. At room temp, water is the best. Now, if you have a freezer or a fridge, then things may change; liquid nitrogen spray, for instance, in limited quantities (so it doesn't freeze your intercooler), would be proper damn mad.
Would probably be better if you live in a cold area to just put windshield wiper fluid in it. That way it is cheap, readily purchasable, and if it gets cold out then you don't have to worry about flushing the water system in the fall.
I don't know if somebody else have said it but I think it would be better to use the water pump of the wipers (sorry if my English is not very good, my maternal language is Spanish). It's a button and spray water with good pressure. Just an idea. Great show!
Sure would but since the water in your radiator has a much higher heat capacity than the air in your intercooler you'll need a whole lot more water sprayed onto it to see a drop of 1 degree; good for emergency cooling, not practical on the road or track as part your cooling system. Also be mindful how much water is going to end up in the engine bay if you decide to hose your radiator.
If your car has problems with overheating, your best bet is to increase the reservoir capacity. This provides more of a "buffer zone" to keep it cool until you're slowing down again. Since I'm guessing you're driving a non-turbo, you could add a second radiator into the bonnet where the WRX STi has its stock intercooler. Really though if you're getting that much temperature you should just get a new bumper and radiator with more area.
bringingtherukas Aluminium isn't as prone to tempering as steel, and it certainly won't happen at the temperatures a radiator or intercooler will see. Your pistons would be melting before the water would damage the radiator.
It wouldn't do anything. All cars have a thermostat fixed between 170-200F. Your engine temp is only going to move out of that range if something is wrong. Radiators keep the engine temp in the right place with antifreeze and intercoolers are optional and used to cool air for boost.
Way don't they use a cheap window washer bottle. cheap takes up little room and u just use a button rather then pumping it every time you want a little spray. Lol
You guys should do water injection directly into the intake after the intercooler. It will be more efficient at cooling intake temps and have the bonus of cleaning the top end of your MX5. Water is not compressable so don't add too much. Repurpose your windshield washer resevoir and pump. Fill it with water and redirect line to inject water through a nozzle into the intake. Mount a switch so you don't look like a fool pumping that bottle of yours. Come on, MX5s have a bad enough rap without you pumping that ridculous thing.
That is called water injection, you need a new tune for that. And this was supposed to be a supreme low budget thing, they could do it up nice if they really wanted to.
That also means you have more water inside your cylinder does it not (be it as condensation or vapour)? Water has high specific heat capacity, meaning the actual combustion temperature in the engine will be lower -> bad for efficiency
Bramnero Not bad, it means you effectively have higher octane gas (because the cooling keeps it from detonation [knocking]), so you can run more boost, and more advanced timing. BIIIIG power gains can be had with a water injection system.
10 % drop in temperature? it rally depends where you start measuring. like is 1:48pm a 10% drop from 2:00pm? I'd still be interested in some power figures. that presumably is the ultimate point. you could start with a garden hose on the dyno and work down.
To get a 10°c drop they should have started at a ambient temp of -32°c. The real % drop was actually higher, for example, if you consider a 24°c ambient temp, the drop would be of 33.33%, considering as constants to the other temps given.
flagpoleeip yes, you would be right if you were considering range values of the universe, which we are not. We are talking about the operational temperatures of the intercooler, as you can't achieve -273°c in this case. The % drop referes to the minimum and maximum temp variations that the intercooler suffers from this modification (RANGE is the key word people are forgetting).
ArgentineGuy So if I have 10 apples, but I'm only considering 5 of them, then 20% of my 10 apples is 1 apple. That is exactly how you're portraying this. At say 40°C, absolute zero still exists. You can't just ignore it because it's not within the operating temperature. Seriously, go to a local library or college and pick up a textbook on chemistry, general physics, or thermodynamics. The first two are likely to have a chapter on this, especially chemistry. A thermodynamics textbook may or may not discuss this because it's a very basic concept that should be learned in basic chemistry or advanced general physics prior to taking thermodynamics.
A black intercooler increase the temperature because it absorbs heat and reduces the rate of cooling because the paint reduces the air flow through the intercooler.
The standard gain is about 1%Hp for every 10° reduction of intake air temps. The better road traveled is injecting a 50/50 water/ methanol mix which will drop intake air temps depending on the forced induction type and boost from 70 -150 °. The added benefit of methanol is the ability to increase timing, reduce boosted air temps and add even more boost . A win/ win/ win. Only downside is having to refill the methanol mix. A injection system using the before mentioned system with added timing can net alot more hp. 40-50% more rwhp is attainable. If installing on a intercooler car. Inject after the intercooler.
Magnum Opus Actually water injection is used on thousands of high performance cars all over the world, and it reliably reduces intake temperatures to BELOW ambient temperatures, and exhaust gas temperatures to below stock configuration. The best and most well designed air intercooler in the world couldn't do that... ever.
So it seems most people are tapping into the windshield sprayer system to spray the intercooler. My question is how would you be able to do that without triggering the windshield wipers since they swipe whenever you spray washer fluid. My car runs an intercooled centrifugal supercharger kit that uses a really high boost pulley that makes more pressure than the stock intercooler was designed for. A larger intercooler would cause a pressure drop and I cant make my SC produce anymore boost to make up for the loss so Ive considered creating an intercooler sprayer kit to use during our 100°F summers here. However i do not want my windshield wipers to trigger every time I use the sprayer
+Everett Ariaz Painting an intercooler any colour is stupid. The paint only presents an insulative barrier to the cooling process. The best intercooler is clean metal.
Exactly, MCM tested it, and proved that the non painted intercooler was more efficient in the video but for some reason didn't seem to realise it at the time. They were basing it originally off doing it without airflow through the cooler, which is not how it works, intercoolers rely on convection to transfer heat. So as soon as they had an airflow source we saw the non painted cooler had a larger temperature drop, and that was only with a little hairdryer. Testing isn't always showing the true nature of it, it depends how the data is interpreted, as is the case here.
Please do a video on water injection for engines. Its benefits are well-known with forced induction, but there are also anecdotal evidence that it can help improve MPG on NA engines with carbs. It would be nice to find out if there are benefits to fuel injection setups.
Sigh;....I think you actually want a 'Hot Air Intake'* to start the combustion process quicker. *(HAI) Engines need to run Hot.... NOT COLD! . Ever hear of an Adiabatic engine? Huh?
You're getting your facts wrong here, the combustion needs to be as hot as possible to work efficiently, but the air entering the cylinders should be as cold as possible. Colder air is more dense therefore a greater amount of air can enter the cylinder for a given volume. Sending hot air into the cylinder can also increase the risks of pre ignition and/or detonation.
FanjitaUK2k8 The key idea here is "air density"; not "air temperature" and predetonation issues. Engines have a more complete combustion when the air intake across the valves is around 92 degrees Fahrenheit; why do you think gas mileage and efficiency and power go down when it gets below freezing? In the arctic regions; the air has to be preheated just so an engine will run. Increase air density (oxygen) and addressing predetonation, gets us on the proper path. But for fun look up Adiabatic engine...an engine that keeps it's heat for greater thermal efficiency, rather than dispelling all that energy out the radiator and tailpipe..
Kenny J Power goes down when it's cold? I think efficiency is increased as well as power. Gas mileage may decrease, but that doesn't mean your car is running less efficiently. The car with a dense air charge will use more fuel (the car's computer will alter the a/f) but can utilize it better than warm air; therefore, produces more horsepower.
Kenny J Fuel efficiency decreases when it gets that cold because the engine itself is colder, not because the intake air is colder. A colder engine is less efficient. Colder air, however, is more efficient, in terms of power output per amount of fuel rather than distance per amount of fuel. The air must be heated because you want the gasoline to be gaseous or at least in a fine mist. Lower temperatures prevent it from vaporizing and/or increase the viscosity, making it harder to maintain a fine mist. If it gets below -40 degrees Celsius in the arctic winters, you risk freezing the gasoline. It's very obvious that there are many more factors involved than you believe there are. Theoretically, a hot engine with cold air and warm fuel would be optimal. Not a hot engine with hot air and hot fuel.
TheSmileyFacedPizza Hey;...Aircraft have air intake pre-heaters to heat up that incoming air....... If you have ever run engines in arctic conditions; low air intake temperature is a major factor along with gelling diesel, and gasoline separation. Believe me, I know from experience working in the north slope of Alaska. We knew when that frigid air hits the combustion chamber no amount of air/oxygen density is going to make good combustion when the air/fuel mixture is still freezing cold. But like you say, and I say; there are many complex factors in the combustion process in relation to producing power. "Hot air intake charge" is one design parameter for certain applications. (BTW, my first post was kind of trolling for arguments)
Hi Marty and Moog. I live in Melbourne and I'm thinking you guys live in NSW because a lot of your episodes where you film at your garage, I can hear the crickets outside and I also noticed because you went to the eastern creek track and there are lots of gumtrees. I always wished you guys lived in melbourne so I could go to your store/mechanic garage and ask you guys for advice on buying a new car. I want Nissan Skyline R33 GTR or a 1998 Toyota Supra (single turbo on both). You guys are the best and you really inspire me to become a racecar driver or a drifter or something like that! :D
Because it doesn't work. Black radiator/ intercool only makes it cooler at a stop if you don't have a fan going. It would be a complete waste of money since modern cars come with a fan to pull air through the radiators at a stop.
Doppelkupplung it's an intercooler not a radiator. most cars don't have fans attached to factory intercoolers. side note: ive seen you commenting a lot of incorrect information lately on other videos, please read up before you post. there's too many young minds that soak up everything they read and immediately think they are mechanical engineers. the outbreak of idiocy on youtube is more of a concern than ebola, don't be a part of it
steve6493 except he's right... if you'd like proof of it you can watch MCM's video on it where they say that exact thing. Black only assists if there is no airflow, if there is airflow the black does nothing..
Do you want to install this on your own car? HELL NO FOOL! Just imagine that you are at a drag strip or traffic lights with this setup, you start pumping and people around you will look at you thinking that your wanking, come on now! If you are gonna do something then do it properly and correctly.
1. no 1 would blame you for doing so. 2. they only did this for gags really, he'll prob. do a setup using a window washer tank/ motor in the engine bay. also just a cool thing for the drags, my buddy wired up 2 window washer tanks in the trunk that would spray right behind the tires so u spray, back up, burnout, ready to go.
Sticking with the budget theme, locally I can get a 2 gallon pump up sprayer for $10 USD. I use it on weeds. It will spray for a few minutes without issue. I really think that would have kept with the budget idea and really saved some work.
Just under $50, that's amazing. I'll probably do the one marty explains in the previous video where you can connect it to the rear winsdhield sprayer instead, but I think having a giant water sprayer duct taped under the dash really adds the +25 kilowatts.
I have a mondeo st tdci in england all i have done with mine is took the light washer jets out and face them towards the intercooler andit works fantastic :-) did it about 6 months ago
Perfect, exactly what I was looking for. My BMW is known to be limited by its mediocre cooling and as it is an old car and I am a broky I dont wanna by a new intercooler for >500$. This might be my way to go.
Actually I would love to see a proper 2 door Laser TX3 turbo build. What you guys did the last time was quite sad for me. As an owner of an NA TX3 myself, the car has served me very well. It would be a dream to see you guys make some serious power out of a Turbo Laser. :)
What about removing the intercooler, and misting water upstream from the turbo, I've heard great things! you should try it! Also, helps prevent detonation!
You could use some type of venturi valve and run it off vacuum from the intake so a pump isnt required at all. After all your car already has multiple pumps. The main concern would be making the spray bar simple and efficient so that it doesnt require a large tank and muddling up your engine bay with a ton of weight and crap... hmmm. I wish my miata had an intercooler to try this.
How about using a cheap 12 volt electric windshield washer pump with the water reservoir in the trunk or under the hood and instead of that drip type sprinkler use a couple of mister tips that will help to mist the water all over the intercooler. Would be much more effective and have more of an evaporative effect. Good that you guys showed the actual intake temps.
Hi guys,i'm loving yours show Have watched all your episodes,but missing one that you dont have done yet...a DIY about a oil radiatorl! i want to put one on my car but dont know where to connect it right.. plus can you tell what is the + and the - about that?for low power engine? best of luck from Portugal
this is really only practical for turbocharged cars that see red hot turbo manifolds. you dont know the meaning of heat soak until theres a glowing hunk of iron sitting under the bonnet for a few minutes. a DIY electrically operated water mistifier is quite feasibly obtained and could actually make a noticeable difference in power. Its crazy how much power loss i had when the IAT sky rocketed on a hot, muggy ozzy summer day.
What about power gains/loss? Perhaps a Dyno run without the spray as a "before" or base figure then manually spray the inter-cooler fully, wait for the difference in temperature and then do a run? that would be awesome, as i and i'm sure a lot of other people are left wondering, hmmm i wonder if this makes any difference in the power? that would really be a decider as to whether the mod is actually worth undertaking on a car. If it offers power gains of any form i will definitely DIY a second pump onto my washer bottle so i can chop people on the "track" Thanks :D
hey you should paint the spray can black to match your interior and leave just a little line on the side to see how much water you have in it. changing the color will improve your skids mate! MAAAAADDD!!!!
a drop of 4 degrees CELSIUS is not a 10% drop in temperature, since the 0 degree mark is virtual and physically there can be no negative temperatures. but cool videos, I like the myth buster things. :)
If you measure the temperatures as a difference from ambient then its actually about a 40% decrease for both tests. If you measure it as absolute temperature its 1.3% and 2.5%. If you measure in farenheit its 7% and 12%. The 40% figure is probably the useful one.
Actually the useful thing to measure is the difference between the intercooler input and output temperatures, quite like in the BLAAAACK intercooler test. "Does painting it black make any difference?" is pretty much the same as "Does peeing on in with a silly green pump make any difference?"
I was waiting for Moog to say "just make sure their not the ones that go into your bottom" lol at the end.. That would have made this video so much better
Great DIY project, guys.... but I'm worrying about long term effects like rust and corrosion because water normally doesnt get into those areas of the compartment / under the bonnet. Any opinions on how to angle the install or just aim it straight at the intercooler and simply have the intercooler take full brunt of spray blast? Any opinions on over long term effects, potential negative impacts (if any) it may have?
Guys, You are only seeing a few degrees drop. The delta is way too small to make a big difference. Please try a water methanol injection setup. You dont have to manually pump anything, and it drops your intake air temps DRASTICALLY! 140 deg F, to around 60 deg F. Its a MASSIVE difference. The MX5 is begging for it. In addition, the methanol acts as a huge octane booster, giving you the ability to run more timing...which means more power.
Not to mention you can rig up a system like that on the cheap, and kits are still cheap when bought. You can also run it on just water and see improvements as well. Water-Meth is the way to go for sure.
Well it does work 8 degrees is ok for a pretty crude set up probably not as effective as spraying the water into the charge air itself tho still a decent VIdeo thanks guys
I'd love to see you guys do some Mitsubishi cars, like the early gen EVO's or get a Galant VR-4.....I know you guys didn't get the eclipse/talon/laser line up (which would be right up your ally) But did you guys get the 3000GT's?
Keep in mind the air speed at the upper end... Where is that water landing and would more nozzles be better. The faster the air moves the fast water evaporates.
Im getting 65 to 70 in this years summer when running the AIrcon and with 98 at 1.82+ per L ive been thinking about doing a water mister not simply a jet of water but high pressure misters that also cool the air, whilst wetting the intercooler (better Evap) Hopping it will cool the aircon and the intercooler behind it.
How long did it take to cool down that much? For instance if you were racing, you are only boosting for so long, so would there be any HP/TQ gain in this?
![ปฏิเสธไม่ไหว (Crush on you) - LIPTA feat. No One Else [Official MV]](http://i.ytimg.com/vi/NBw1jF342vw/mqdefault.jpg)
I love it when you guys actually test out your cheap DIY mods properly on the dyno
same
same, shows how cheap things can be effective too
That little sprayer also is only hitting a small part of the intercooler, multiple sprayers or the small misting garden hose works very well for wetting the whole intercooler.
Tyl3rKrupa Yep. This test was about as half-assed as it gets
Using the spray inside the pipe is even better, water droplets will enter the intake and the compression stroke will increase engine's thermal efficiency, while the water droplets absorb heat, and if they become steam, increase exhaust gas pressure, achieving top boost sooner
Another good idea and also on a budget is actually using one of the windshield sprayers which actually has a little motor that jet sprays just extend the hose and run it to your intercooler and spray just by pulling your wiper controls instead of pumping while you driving and come with own little water tank! :)
I think this was suggested in the other video. Definitely the most efficient and cleanest way of doing it.
Thats actually a great idea
WOW! You guys have come a long way in the last 6 years!
Just move your windshield washer lines to in front of the intercooler
Actually not a bad idea, 😂
+shawn upole Windshield washers aren't required for inspection. At least not in Texas.
Here you technically don't even need a windshield.
If you have one, you need to be able to see through it though.

I expect Leon Duray used to aim for puddles to go faster.

Even though this video was really short, I'm still so happy you guys made a video. Best subscription I've made on youtube is to you guys! Keep it up! And I'm looking forward to the s2k mods :D
That's an impressive drop for something so simple and dodgy... I LOVE IT
For a DIY project of common household items, that pretty awesome to see such a decent amount of temperature drop. Good on you guys
Can u imagine seeing that at traffic lights lololol@ 1:23 sorry guys cameraman nailed you Martin
Great to see u guys back in the driveway doing diy. I like these episodes better.
Throw some ice cubes in the pump and u got yourself even colder water.
Might not want to do that. Throwing ice cold water on a hot metal can lead to cracking.
petey2crazy Not aluminium. Definitely true for tempered steel, but mild steel/iron or aluminium is fine. This is why watercooling for brake discs (which get way hotter than intercoolers) is fed to the mild steel core of the disc and never the tempered friction surface.
petey2crazy its not THAT hot.
Yeah that makes sense. Radiators and intercoolers can withstand freezing rain and snow. Please ignore my previous statement.
Or, just get a small refrigerator compressor and put the pipes up against the intercooler and basically freeze it.
Guys are on the other side of the world and doing mad stuff! Brilliant.
Test Methanol & water injection
was awesome meeting you guys yesterday! hopefully see more behind the scenes stuff! MAAAAAD
Try a CO2 chilling system. Much colder than water & no issues with water that doesnt evaporate & then ends up under your tires. The liquid CO2 in the tank will turn to gas as it sprays therefore cooling much better & zero will drip onto the road.
Thanks for not taking something that can be explained in 2 minutes and stretching into a 30 minute episode like so many modern TV shows do these days.

For N/A cars, people would re route the A/C compressor lines that have freon in it, you know, make up another line, and actually wrap that line around their fuel rail. Supposed to drastically decrease the temp of the fuel being injected into the cylinders. The reason I wonder if it really works, is if the change in fuel temp, actually makes it burn better. In theory it should work, maybe that would make a good mythbusting episode?
Would be a lot more useful to cool intake air.
Eero Vuori
it's for the longevity of the engine and turbo system.
Brandon Camejo should lead to no measurable difference. fuel density does not change that much with temperature as air density does. The amount of fuel injected in comparision to air is extrem. Cold fuel has a higher viscosity, this will destroy your fuel injection system faster in the long run, as more work has to be done. (especially for diesel)
You could always rig this to a secondary tank with a pump that activates with a micro switch under the gas pedal that way it only turns on under high load.
They have an aftermarket ECU, with some tinkering there is probably a way to map the sprayers to engine load/manifold pressure/ambient temperature and have it automatic.
"Tested on Dyno", I tought I'd see horsepower improvements upon WOT accelerarion!
That's what I was expecting too, where's the dyno chart showing an improvement to bhp?
Several people are saying that Moog saying it's a 10% drop is wrong because when done in the Kelvin scale it works out to be a drop in temp from 313 to 309 (or something like that). I think only way you could measure the effectiveness would be in measuring change in temperature (or deltaTemp if you will!) from ambient. It'd have to be from ambient, because a basic air-to-air intercooler with no cooling spray or anything will not get the intake charge cooler than ambient. It's impossible. So, Moog says that the ambient temperature is about 30C. At 40C the change in temperature would be 10C, but the extra 4C drop from the spray brings it down to 6C. That would mean the intercooler would be 40% cooler!
Let's look at the second set of readings. At 48C, the change in temp would be 18C. Spray the intercooler and get an 8C drop, to 40C, which is a roughly 45% drop! Not too bad!
(Edited because I didn't realize they mention the ambient temp.)
Watercooling for your watercooling!
+BrainSeepsOut Mcm xzbit style.
+BrainSeepsOut this watercooling fpr your aircooling but no problem.
that they achieved as much as they did with such a small setup (single nozzle) with relatively low water flow speaks to how well the concept works. If you have a multi nozzle setup triggered by boost it would be much more effective when needed.
I was just about to go to sleep. Glad I didn't.

That's pretty good for something worth under $50. But my computer runs hotter than that on idle. No it's not broken, that's normal computer temps for someone on stock cooler. But still, I think it's time for an upgrade. Thermal compound must be burnt at this point.
My old 6970 used to idle at around 50 and would jump up to 85 when i was gaming. my new 290x runs nice and cool idling around 30 and only gets to about 45-50 when gaming.
U do understand that is the temperature of the air coming from the atmosphere to the turbo? Its not the same as the radiator stopping the engine from overheating which would be the equivalent of you comparing the temp of ur cpu on ur pc.
Mine idles at around 22 degrees celcius with an ambient temperature of 32 degrees, god I love big air coolers.
Nitris Yeah I know... But I still don't like the fact that my computer is at 30-50 on semi idle mode.
Tank77 I was talking about my cpu -_- And I really don't like you. I still have my crap 660 and was wanting to upgrade.
so glad they've done something proper DIY again
You said 4C drop from 40C is a 10% drop. That's not actually correct. Celsius is measured from 273C above absolute zero. So actually its a drop of 4C from 313Kelvin, as 1 Celsius is equal to 1Kelvin. That's 1.2% difference in actual temp lost from the system.
it's all about the delta T, when it comes to cooling performance
Yup. Delta T is more important than percent from absolute zero.
In the end it's about air density, which is inversely proportional to the T° in K at constant pressure (ideal gas law).
Gain in density = (1/T1 - 1/T0) / (1/T0) = (T0 - T1) / T1 = 4 / 309 = 1.29%
Almost the same as the drop in temperature for small variations.
What if you guys used a mister system with several heads to cover the entire intercooler. A mister system would cool the air before it hits the intercooler. I live in Arizona in the states so I know a bit about evaporative cooling. I can relate to you guys lol. Cool show by the way. Love watching it
Mighty Car Mods I sorta miss the "Old Australian guys" intro thing you guys had for the Gramps video. :( lol
Now guys test the water methanol injection system to see the gains in a dyno and awsome vids like allways
In America we mount the spray nozzles on the dash aimed to cool down the driver.
Yeah!..... 'Merica!
good to see some actual results.
How about 50/50 mix of water and rubbing alcohol
Water is better; it has a higher specific heat than rubbing alcohol, so it takes more heat away. Rubbing alcohol will just evaporate faster; but water, especially at speed, on a hot intercooler, should be more effective.
Evaporation is a cooling process however, it may have an impact.
Jesse Nicola Evaporation, yes.
But alcohol will definitely have a negative effect.
Alcohol evaporates easier; it requires less heat to evaporate; therefore, alcohol takes less heat away; that is how the evaporation cooling process works.
Trust me, we did this in chem class with calorimeters.
The heat capacity of the liquid (or fluid) and initial temperature (for overall temperature change of fluid, which when you multiply in Q=mcdeltat (deltat being change in temp. c being specific heat and m being mass) are what matter most.
With alcohol and water, both at room temp (most likely, in a car), because the specific heat of alcohol is lower, you would need much more alcohol to match the cooling potential of water. No, sorry, a 50/50 or any mix is a bad idea. At room temp, water is the best.
Now, if you have a freezer or a fridge, then things may change; liquid nitrogen spray, for instance, in limited quantities (so it doesn't freeze your intercooler), would be proper damn mad.
Would probably be better if you live in a cold area to just put windshield wiper fluid in it. That way it is cheap, readily purchasable, and if it gets cold out then you don't have to worry about flushing the water system in the fall.
rambow70 Yeah, cold weather, you can even just fill it with vodka #justRussianthings
I don't know if somebody else have said it but I think it would be better to use the water pump of the wipers (sorry if my English is not very good, my maternal language is Spanish). It's a button and spray water with good pressure. Just an idea.
Great show!
Would this work at all on a normal radiator since there is already liquid inside? Kinda a dumb question, but I'm curious.
Sure would but since the water in your radiator has a much higher heat capacity than the air in your intercooler you'll need a whole lot more water sprayed onto it to see a drop of 1 degree; good for emergency cooling, not practical on the road or track as part your cooling system. Also be mindful how much water is going to end up in the engine bay if you decide to hose your radiator.
If your car has problems with overheating, your best bet is to increase the reservoir capacity. This provides more of a "buffer zone" to keep it cool until you're slowing down again. Since I'm guessing you're driving a non-turbo, you could add a second radiator into the bonnet where the WRX STi has its stock intercooler. Really though if you're getting that much temperature you should just get a new bumper and radiator with more area.
Tom Ault
what about the fact its cold water on a hot surface, is there possible damage that might occur ?
bringingtherukas
Aluminium isn't as prone to tempering as steel, and it certainly won't happen at the temperatures a radiator or intercooler will see. Your pistons would be melting before the water would damage the radiator.
It wouldn't do anything. All cars have a thermostat fixed between 170-200F. Your engine temp is only going to move out of that range if something is wrong. Radiators keep the engine temp in the right place with antifreeze and intercoolers are optional and used to cool air for boost.
Good video guys, almost at 1 MILLION subscribers!!!! Congratulations!!!
Way don't they use a cheap window washer bottle. cheap takes up little room and u just use a button rather then pumping it every time you want a little spray. Lol
danny watson Because the way they did it was cheap, quick and simple.
You guys should do water injection directly into the intake after the intercooler. It will be more efficient at cooling intake temps and have the bonus of cleaning the top end of your MX5. Water is not compressable so don't add too much. Repurpose your windshield washer resevoir and pump. Fill it with water and redirect line to inject water through a nozzle into the intake. Mount a switch so you don't look like a fool pumping that bottle of yours. Come on, MX5s have a bad enough rap without you pumping that ridculous thing.
That is called water injection, you need a new tune for that. And this was supposed to be a supreme low budget thing, they could do it up nice if they really wanted to.
nutnfan1 water meth would be pretty badass on gramps...
That also means you have more water inside your cylinder does it not (be it as condensation or vapour)? Water has high specific heat capacity, meaning the actual combustion temperature in the engine will be lower -> bad for efficiency
Bramnero Not bad, it means you effectively have higher octane gas (because the cooling keeps it from detonation [knocking]), so you can run more boost, and more advanced timing. BIIIIG power gains can be had with a water injection system.
nutnfan1 Interesting! I didn't thank about that effect, could be cool =)
I do appreciate the lengths you go to just to test a 10$ mod for us. Good work Gents
10 % drop in temperature? it rally depends where you start measuring. like is 1:48pm a 10% drop from 2:00pm?
I'd still be interested in some power figures. that presumably is the ultimate point. you could start with a garden hose on the dyno and work down.
To get a 10°c drop they should have started at a ambient temp of -32°c. The real % drop was actually higher, for example, if you consider a 24°c ambient temp, the drop would be of 33.33%, considering as constants to the other temps given.
you can't measure temps in percentage terms unless you start at absolute zero. −273.15°
flagpoleeip yes, you would be right if you were considering range values of the universe, which we are not. We are talking about the operational temperatures of the intercooler, as you can't achieve -273°c in this case. The % drop referes to the minimum and maximum temp variations that the intercooler suffers from this modification (RANGE is the key word people are forgetting).
flagpoleeip And as you are considering a RANGE, calculating in kelvin is also irrelevant, as the ΔT° is the same in °c or kelvin.
ArgentineGuy So if I have 10 apples, but I'm only considering 5 of them, then 20% of my 10 apples is 1 apple. That is exactly how you're portraying this. At say 40°C, absolute zero still exists. You can't just ignore it because it's not within the operating temperature. Seriously, go to a local library or college and pick up a textbook on chemistry, general physics, or thermodynamics. The first two are likely to have a chapter on this, especially chemistry. A thermodynamics textbook may or may not discuss this because it's a very basic concept that should be learned in basic chemistry or advanced general physics prior to taking thermodynamics.
glad to see you back on TH-cam guys :) !!! Keep it coming
But....Your intercooler. It's not black! What is up with that???
A black intercooler increase the temperature because it absorbs heat and reduces the rate of cooling because the paint reduces the air flow through the intercooler.
The standard gain is about 1%Hp for every 10° reduction of intake air temps. The better road traveled is injecting a 50/50 water/ methanol mix which will drop intake air temps depending on the forced induction type and boost from 70 -150 °. The added benefit of methanol is the ability to increase timing, reduce boosted air temps and add even more boost . A win/ win/ win. Only downside is having to refill the methanol mix. A injection system using the before mentioned system with added timing can net alot more hp. 40-50% more rwhp is attainable. If installing on a intercooler car. Inject after the intercooler.
1 million subs comming up what car do u guys want them to buy ??? Me i want to see a r33 or r32
Why something different why not something people have
2015 Rolls Royce Phantom, then mod the hell out of it!!!! lol
Some sort of Rotary
xLeionx yessssss even better the a skyline a 93 rx7 or a rx8 would be sick
Nato Ward
well JDM is heavily influenced on the show.
Worth hooking up a proper system, like you guys suggested with the rear window washer bottle
Or just inject that water into the engine... way bigger cooling effect
risk of thermal shock in my opinion
temp diff isn't as high as it would be with the engine with the intercooler
Magnum Opus Actually water injection is used on thousands of high performance cars all over the world, and it reliably reduces intake temperatures to BELOW ambient temperatures, and exhaust gas temperatures to below stock configuration. The best and most well designed air intercooler in the world couldn't do that... ever.
My bad
Magnum Opus All good dude! Look up water methanol injection... it truly does wonders
Magnum Opus it's cool technology that's been around since ww2 in use in supercharged airplanes.
So it seems most people are tapping into the windshield sprayer system to spray the intercooler.
My question is how would you be able to do that without triggering the windshield wipers since they swipe whenever you spray washer fluid.
My car runs an intercooled centrifugal supercharger kit that uses a really high boost pulley that makes more pressure than the stock intercooler was designed for. A larger intercooler would cause a pressure drop and I cant make my SC produce anymore boost to make up for the loss so Ive considered creating an intercooler sprayer kit to use during our 100°F summers here. However i do not want my windshield wipers to trigger every time I use the sprayer
black paint intercooler with and without water spray
+Everett Ariaz Painting an intercooler any colour is stupid. The paint only presents an insulative barrier to the cooling process. The best intercooler is clean metal.
+keith sachs (Flukz) No, they tested it wrong. Check out Engineering Explained for the full explanation.
Steve S I take it you have an engineering degree?
Exactly, MCM tested it, and proved that the non painted intercooler was more efficient in the video but for some reason didn't seem to realise it at the time.
They were basing it originally off doing it without airflow through the cooler, which is not how it works, intercoolers rely on convection to transfer heat. So as soon as they had an airflow source we saw the non painted cooler had a larger temperature drop, and that was only with a little hairdryer.
Testing isn't always showing the true nature of it, it depends how the data is interpreted, as is the case here.
I really don't care, I just think it looks cool
Please do a video on water injection for engines. Its benefits are well-known with forced induction, but there are also anecdotal evidence that it can help improve MPG on NA engines with carbs. It would be nice to find out if there are benefits to fuel injection setups.
Sigh;....I think you actually want a 'Hot Air Intake'* to start the combustion process quicker. *(HAI)
Engines need to run Hot.... NOT COLD!
.
Ever hear of an Adiabatic engine? Huh?
You're getting your facts wrong here, the combustion needs to be as hot as possible to work efficiently, but the air entering the cylinders should be as cold as possible. Colder air is more dense therefore a greater amount of air can enter the cylinder for a given volume. Sending hot air into the cylinder can also increase the risks of pre ignition and/or detonation.
FanjitaUK2k8
The key idea here is "air density"; not "air temperature" and predetonation issues. Engines have a more complete combustion when the air intake across the valves is around 92 degrees Fahrenheit; why do you think gas mileage and efficiency and power go down when it gets below freezing? In the arctic regions; the air has to be preheated just so an engine will run.
Increase air density (oxygen) and addressing predetonation, gets us on the proper path.
But for fun look up Adiabatic engine...an engine that keeps it's heat for greater thermal efficiency, rather than dispelling all that energy out the radiator and tailpipe..
Kenny J
Power goes down when it's cold?
I think efficiency is increased as well as power. Gas mileage may decrease, but that doesn't mean your car is running less efficiently. The car with a dense air charge will use more fuel (the car's computer will alter the a/f) but can utilize it better than warm air; therefore, produces more horsepower.
Kenny J Fuel efficiency decreases when it gets that cold because the engine itself is colder, not because the intake air is colder. A colder engine is less efficient. Colder air, however, is more efficient, in terms of power output per amount of fuel rather than distance per amount of fuel. The air must be heated because you want the gasoline to be gaseous or at least in a fine mist. Lower temperatures prevent it from vaporizing and/or increase the viscosity, making it harder to maintain a fine mist. If it gets below -40 degrees Celsius in the arctic winters, you risk freezing the gasoline. It's very obvious that there are many more factors involved than you believe there are. Theoretically, a hot engine with cold air and warm fuel would be optimal. Not a hot engine with hot air and hot fuel.
TheSmileyFacedPizza
Hey;...Aircraft have air intake pre-heaters to heat up that incoming air.......
If you have ever run engines in arctic conditions; low air intake temperature is a major factor along with gelling diesel, and gasoline separation. Believe me, I know from experience working in the north slope of Alaska. We knew when that frigid air hits the combustion chamber no amount of air/oxygen density is going to make good combustion when the air/fuel mixture is still freezing cold. But like you say, and I say; there are many complex factors in the combustion process in relation to producing power.
"Hot air intake charge" is one design parameter for certain applications. (BTW, my first post was kind of trolling for arguments)
Hi Marty and Moog. I live in Melbourne and I'm thinking you guys live in NSW because a lot of your episodes where you film at your garage, I can hear the crickets outside and I also noticed because you went to the eastern creek track and there are lots of gumtrees. I always wished you guys lived in melbourne so I could go to your store/mechanic garage and ask you guys for advice on buying a new car. I want Nissan Skyline R33 GTR or a 1998 Toyota Supra (single turbo on both). You guys are the best and you really inspire me to become a racecar driver or a drifter or something like that! :D
Why not spraying it black for more hp
Because it doesn't work. Black radiator/ intercool only makes it cooler at a stop if you don't have a fan going. It would be a complete waste of money since modern cars come with a fan to pull air through the radiators at a stop.
Doppelkupplung it's an intercooler not a radiator. most cars don't have fans attached to factory intercoolers.
side note: ive seen you commenting a lot of incorrect information lately on other videos, please read up before you post. there's too many young minds that soak up everything they read and immediately think they are mechanical engineers. the outbreak of idiocy on youtube is more of a concern than ebola, don't be a part of it
steve6493
except he's right...
if you'd like proof of it you can watch MCM's video on it where they say that exact thing.
Black only assists if there is no airflow, if there is airflow the black does nothing..
ei8ht 6ix That's his point.
steve6493 Apart from the fan thing, he's correct on everything else
That's what you should have done with the black painted radiator video! Other than that just a great piece of information, thanks guys!
Do you want to install this on your own car? HELL NO FOOL!
Just imagine that you are at a drag strip or traffic lights with this setup, you start pumping and people around you will look at you thinking that your wanking, come on now! If you are gonna do something then do it properly and correctly.
thats what I do right before a race...
1. no 1 would blame you for doing so. 2. they only did this for gags really, he'll prob. do a setup using a window washer tank/ motor in the engine bay. also just a cool thing for the drags, my buddy wired up 2 window washer tanks in the trunk that would spray right behind the tires so u spray, back up, burnout, ready to go.
Have seen it on TDI's the used nos on the intercooler it realy helps when you tune your diesel !
Sticking with the budget theme, locally I can get a 2 gallon pump up sprayer for $10 USD. I use it on weeds. It will spray for a few minutes without issue. I really think that would have kept with the budget idea and really saved some work.
Keep up the good work, guys! I really enjoy your guys' stuff
Just under $50, that's amazing. I'll probably do the one marty explains in the previous video where you can connect it to the rear winsdhield sprayer instead, but I think having a giant water sprayer duct taped under the dash really adds the +25 kilowatts.
I have a mondeo st tdci in england all i have done with mine is took the light washer jets out and face them towards the intercooler andit works fantastic :-) did it about 6 months ago
Perfect, exactly what I was looking for.
My BMW is known to be limited by its mediocre cooling and as it is an old car and I am a broky I dont wanna by a new intercooler for >500$. This might be my way to go.
Actually I would love to see a proper 2 door Laser TX3 turbo build. What you guys did the last time was quite sad for me. As an owner of an NA TX3 myself, the car has served me very well. It would be a dream to see you guys make some serious power out of a Turbo Laser. :)
HAPPY 1,000,000 SUBCRIBERS!!!!!
Good job of testing.
The results are better than I expected.
Tested intercooler water spray on my old 200sx with front mount on a hot 38 degree day was good for 14 hp at wheels. good mod..
What about removing the intercooler, and misting water upstream from the turbo, I've heard great things! you should try it! Also, helps prevent detonation!
You could use some type of venturi valve and run it off vacuum from the intake so a pump isnt required at all. After all your car already has multiple pumps. The main concern would be making the spray bar simple and efficient so that it doesnt require a large tank and muddling up your engine bay with a ton of weight and crap... hmmm. I wish my miata had an intercooler to try this.
How about using a cheap 12 volt electric windshield washer pump with the water reservoir in the trunk or under the hood and instead of that drip type sprinkler use a couple of mister tips that will help to mist the water all over the intercooler. Would be much more effective and have more of an evaporative effect. Good that you guys showed the actual intake temps.
You just took the washer pump idea from the previous episode lol try again
Supermotard454 Nope, I never watched the previous episode. Just makes sense is all. These guys hack cars up.
Hi guys,i'm loving yours show
Have watched all your episodes,but missing one that you dont have done yet...a DIY about a oil radiatorl!
i want to put one on my car but dont know where to connect it right..
plus can you tell what is the + and the - about that?for low power engine?
best of luck from Portugal
this is really only practical for turbocharged cars that see red hot turbo manifolds. you dont know the meaning of heat soak until theres a glowing hunk of iron sitting under the bonnet for a few minutes. a DIY electrically operated water mistifier is quite feasibly obtained and could actually make a noticeable difference in power. Its crazy how much power loss i had when the IAT sky rocketed on a hot, muggy ozzy summer day.
What about power gains/loss?
Perhaps a Dyno run without the spray as a "before" or base figure then manually spray the inter-cooler fully, wait for the difference in temperature and then do a run? that would be awesome, as i and i'm sure a lot of other people are left wondering, hmmm i wonder if this makes any difference in the power? that would really be a decider as to whether the mod is actually worth undertaking on a car. If it offers power gains of any form i will definitely DIY a second pump onto my washer bottle so i can chop people on the "track"
Thanks :D
Awesome vid:) so when u guys going to do up a Datsun 1200 ute?
Would this be any good on a radiator on a hot day ? , would of been nice to see a twin set up being on the intercooler and radiator.
hey you should paint the spray can black to match your interior and leave just a little line on the side to see how much water you have in it. changing the color will improve your skids mate! MAAAAADDD!!!!
Omg nearly at 1 million subs. Keep up the good work marty & moog 👍
a drop of 4 degrees CELSIUS is not a 10% drop in temperature, since the 0 degree mark is virtual and physically there can be no negative temperatures.
but cool videos, I like the myth buster things. :)
If you measure the temperatures as a difference from ambient then its actually about a 40% decrease for both tests. If you measure it as absolute temperature its 1.3% and 2.5%. If you measure in farenheit its 7% and 12%. The 40% figure is probably the useful one.
Actually the useful thing to measure is the difference between the intercooler input and output temperatures, quite like in the BLAAAACK intercooler test.
"Does painting it black make any difference?" is pretty much the same as "Does peeing on in with a silly green pump make any difference?"
Vladimir Jossifov
Either should work as they're both relevant reference points where-as 0C and 0F are not.
CONGRATS YOU HIT A MILLION YAYYYYYYY NOW DO ANOTHER VIDEO WHERE YOUR S200 GETS CHOPPED
Congratulations on one million subscriptions!!!!!!!!!!!!!
Now fill the bottle with 50/50 distilled water/isopropyl alcohol.. curious to see how low the extra evap will allow the temps to get.
I don't think spraying a flammable liquid through an intercooler and probably onto an exhaust manifold is a good idea.
Good follow up boys!
Almost at the million subs mark!
I was waiting for Moog to say "just make sure their not the ones that go into your bottom" lol at the end.. That would have made this video so much better
Would it help more if there was a coolant and water mix in pump?
Great DIY project, guys.... but I'm worrying about long term effects like rust and corrosion because water normally doesnt get into those areas of the compartment / under the bonnet.
Any opinions on how to angle the install or just aim it straight at the intercooler and simply have the intercooler take full brunt of spray blast?
Any opinions on over long term effects, potential negative impacts (if any) it may have?
I wanted to hear some sweet engine and snail noises, but still a good video like always guys!
wooh second! I was hoping there would be a video like this to put the water sprayers to the test!
Guys, You are only seeing a few degrees drop. The delta is way too small to make a big difference. Please try a water methanol injection setup. You dont have to manually pump anything, and it drops your intake air temps DRASTICALLY! 140 deg F, to around 60 deg F. Its a MASSIVE difference. The MX5 is begging for it. In addition, the methanol acts as a huge octane booster, giving you the ability to run more timing...which means more power.
Not to mention you can rig up a system like that on the cheap, and kits are still cheap when bought. You can also run it on just water and see improvements as well. Water-Meth is the way to go for sure.
Hey, got an idea, how about installing a more hi tech system of this DIY to the gramps, I'd like to see the improvements.
Would this be useful on a radiator as well or would it not be as effective?
It is not 10% drop since the Celsius scale does not start at absolute zero kelvin. It is a drop of 4/313*100 = 1.3%, still a nice drop in temp!
Well it does work 8 degrees is ok for a pretty crude set up probably not as effective as spraying the water into the charge air itself tho
still a decent VIdeo thanks guys
I'd love to see you guys do some Mitsubishi cars, like the early gen EVO's or get a Galant VR-4.....I know you guys didn't get the eclipse/talon/laser line up (which would be right up your ally) But did you guys get the 3000GT's?
+1 on VR-4
Keep in mind the air speed at the upper end... Where is that water landing and would more nozzles be better. The faster the air moves the fast water evaporates.
When you go to the drags you can put ice into your sprayer and get even cooler temps for more power.
Yeah been waiting for this
U guys need to visit the Gatebil Event in Norway next year!
I wonder what the test results would say with some alcohol in the water, cheap vodka or isopropyl maybe
Im getting 65 to 70 in this years summer when running the AIrcon and with 98 at 1.82+ per L ive been thinking about doing a water mister not simply a jet of water but high pressure misters that also cool the air, whilst wetting the intercooler (better Evap) Hopping it will cool the aircon and the intercooler behind it.
How long did it take to cool down that much? For instance if you were racing, you are only boosting for so long, so would there be any HP/TQ gain in this?
Better yet, do a water/meth/alky injection kit and test that. On the turbo Miata, it will make nice gains, especially with more boost/timing.
I got water/meth on a turbo Miata, impressive gains
great channel, just found it today
