How intercoolers work. Air-to-air intercooler vs air-to-water intercooler. Bar and plate vs. tube and fin. Intercoolers are used to cool the intake charge of forced induction engines. By cooling the intake air, the air is more dense and thus has more oxygen, allowing the engine to burn more fuel in each cylinder, and increasing power. There are many types of intercoolers; this video features an air-to-air bar and plate Yonaka intercooler.

Superstuffed i was going to say the same thing

@EngineeringExplained 10 лет назад

Correct, there are several solutions to this however. Vacuum brakes will also have a 1 way valve to hold the vacuum in the chamber to use for braking, so when the car idles or loses boost, it will create the vacuum again. A vacuum pump or hydraulic booster could also be used.

@EngineeringExplained 10 лет назад

Bigger turbos will typically be used for higher boost, yes the correlation is there, but of course they are not all created equal. You want to match the turbo to the power you'd like to make, so that it doesn't have much lag, and spools up quick enough.

@CenobiteBeldar 4 года назад

*taps cowbell 4 times* 🎶We just got a intercooler We just got a intercooler We just got a intercooler Wonder how it works! 🎶

@EngineeringExplained 10 лет назад

Depends of course, but it could easily be 50-100 deg F. Higher or lower depending on boost levels and intercooler size.

@EngineeringExplained 10 лет назад

I hope to eventually!

@EngineeringExplained 10 лет назад

It's been requested many times, so yes I'll need to get around to it eventually! :)

@goutvols103 7 лет назад

Great video. It would be great to include some temperature data and the drop in temperature that could be expected. Thanks.

@EngineeringExplained 10 лет назад

more* of a pressure loss, but I think that's what you meant. And yes, TMIC often do have the advantage of less piping (and less pressure loss).

@BanditoCGET 10 лет назад

Love your videos man. Great job at explaining things and making it easy for other people who don't know what this parts do.

@EngineeringExplained 10 лет назад

Not necessarily, but it does improve efficiency. At 1.1 bar you'd probably see a healthy gain with an intercooler.

@MisunderstoodKid101 10 лет назад

These videos are amazing. I learn so much. I'm in auto and I have a air to water intercooler and I wasn't sure how it works. Thanks!

@snowy5299 9 лет назад

#1. It is not just restricted air flow that drops the outtake pressure of an intercooler, it is also the drop in temperature, as almost any gas cools it will also decrease in the amount of volume it tends to use. for example, A pressure cooker does not pump air into itself to heat up the contents (as you all know), it heats up the liquid, creating steam (expanding gasses) and thus the rise in pressure, and with a rise in pressure you get a rise in temperature, like in a diesel engine, but once you turn off the pressure cooker... the pressurized chamber will begin to condense until the humidity and pressure return to normal and now your left with cool air again. #2. What about the condensation from hot to cold, will it get into the engine?

@EngineeringExplained 10 лет назад

There's not really any reason to in a road car, as the frontal area is big enough that you can use a rectangle. Ultimately, a big thin rectangle will yield the best results, provided that the space is there.

water intercooler is interesting and was wondering about how they made that possible. Now that I know, I don't think I will ever get one. Way to complex and I would have to do more maintenance in the long run then I really want to. Keep up the great video's as usual :)

The pressure remains nearly the same, because you keep forcing in more air, but the temperature decreases.

@earthdreamsuk6657 4 года назад

Great video, I’ve just installed a larger intercooler on my civic fk8 type r, but now the turbo takes longer to kick in, is this what’s known as turbo lag? I’m getting the car remapped soon, is there a change that will help with this problem. Many thanks 🙏🏼

@1InfinityShade 3 месяца назад

HAHA! I've been watching your channel for years. Now that I have my first turbocharged car, I wanted to learn more about forced induction. Enter Engineering Explained's baby face from 10 years ago XD. I would really like to see an updated version of this video, which delves deeper into the correlation between air temperatures, CFM at given RPMs, and intercooler size.

I know this is an old video but knowing very little about engines and the different components you explained the basic principle really well :P

@EngineeringExplained 10 лет назад

Engine knock, combustion could start before the spark plug fires, and of course a loss of efficiency (and thus, power).

I believe the only difference is straight cut gears vs. helical.

@erikestrada2408 3 года назад

Thanks for the video and all the info. Quick question, I've heard that too big of an intercooler creates lag is that true I want to upgrade for my a5 2.0t b8 also for the piping whats better silcone or aluminum?

@EngineeringExplained 10 лет назад

Long term goal!

@scoobystichris790 6 лет назад

Hi, love the video. Question; would putting gold heat reflective tape on you intercooler reduce heat from the turbo and engine on a top mount intercooler? Or it stop heat from leaving the intercooler? Many thanks 👍

@TrevorGoodchild999 10 лет назад

Great vids! Could you please help me out with the following question. What would happen if I buy bigger aftermarket piping for my front mount intercooler? The stock piping that goes from the turbo to the IC and the one that goes from the IC to the intake manifold have a 2.25 inch diameter all the way through, while the aftermarket ones use silicon couplers to connect to wider 2.75 inch diameter tubes. Would this provide a better flow of air to the engine if the turbo, IC and throttle body are still 2.25 and only part of the piping gets wider?

@rithwikj 10 лет назад

@navyman8903 10 лет назад

So I am guessing since you only spent a short amount of time on the Air to Water it isn't as great for an all around car as the Air to Air. I have a 2008 Bullitt mustang, and I am looking to put a Vortech V3 Air to water intercooled or a Paxton Novi 2200SL Air to Air. For a street track car the Air to Air is probably going to be better/more consistent? It is going to be a DD/weekend warrior on 1/4 mile tracks, and road course tracks. What are your thoughts?

@dham99 5 лет назад

lol glad I'm not the only one who thought instantly of Blue's Clues when I saw this haha... On a side note...the reason I was weary of my heat exchanger (water to air) on my supercharged Cavalier was because of the reliance on a pump. My pump failed during a very spirited run and then on some heavy highway pulls. Well I wasn't monitoring my IAT's at the time and the motor went (piston literally splintered). You wont have that with an air to air, the worse that happens is a charge pipe blows off which you'll know right away. But I've had both and having a sufficient intercooler is definitely key.. my stock Focus ST intercooler is basically useless except for daily driving. Its the only part I need to go stage 3 but it should have been the first part I upgraded to for peace of mind! thanks for another good video! the car community is definitely a better place with people like you taking the time to help others understand how things work!

@jamesgrueser 6 лет назад

I recently purchased a GTI, and I’m hoping to get some good miles out of it. I’ve wondered if installing an aftermarket or upgraded OEM intercooler (Golf R?) may help reduce heat and therefore stress on my motor. If the goal was logevitiy and an OEM+ style of tuning, could a well designed intercooler help extend the life of my engine? I live in the southeast where it is hot and humid. Temps can regularly crest 95-100° from late May - September or November some years. My concern is how heatsoak from normal operations or spirited driving and anything in between could affect longevity when considered in totality.

@chunkymunkey153 10 лет назад

super well explained also the reason sometime you don't want a taller or thicker intercooler is because if you are not running that much boost it will take a longer time for you to hit the boost level your set at aka lag a turbo will lag harder trying to fill the system at 15psi of boost with a big intercooler vs a smaller one

@johnnyohness6610 3 года назад

Great video. As a intercooler newbee my question is (94 Ford f250 IDI diesel) How does one determine the size of a intercooler when in front of the radiator is the AC condenser. Would adding a intercooler restrict airflow to the radiator? Should the intercooler be no bigger than a certain % of that given area in fear of to much air restriction to the radiator? Or does the reduction in temp provided by the intercooler offset or compensate for the reduction in airflow to the radiator? Just wondering. Thanks for making this video.

@shawnstylez3523 8 лет назад

if you leave the stock oem intercooler on and put a Neuspeed MKVI FMIC & FID for example would it help to have a twin intercooler on a 2012 Volkswagen Golf R or GTI

@NaughtyGoatFarm 7 лет назад

I have a small 2.8L Turbo diesel engine in a small truck. In stop start heavy traffic the temperature climbs. The intercooler fins (air to air) are a bit beat up from stones etc. Would replacing the intercooler help with temperature in stop start heavy traffic?

@rob2859 9 лет назад

Great video, filled in a few bits I didn't know already. But i'm still at a loss on what to do. I don't know what's going to be the most efficient for my application. Could I send you some diagrams on my designs and give your thoughts?

@EngineeringExplained 10 лет назад

PV=nRT, everyone! :)

@Sawboyjr 6 лет назад

Can you do a video of what's more beneficial having a intercooler on top of the engine with a scoop on the hood sucking in the air or the intercooler on the lower front end of the car sucking in the air as a typical radiator set up?

@derekbellamy8040 8 лет назад

I have some questions about your video on intercoolers and how they function. From what I gathered width has more of an effect on the cooling process then length, is this correct? I also was wondering if the effect changes for engine types, I'm leaning tordes the idea that it doesn't. The reason I'm asking these questions is I am designing my v mount set up for my 13b and thinking of using a Subaru style top mount intercooler that runs top to bottom rather then the traditional side to side draft. Also I was hoping you could do a video on the v mount and explain how it functions

@EngineeringExplained 10 лет назад

We will see, I'll probably leave it up to everyone to see what they'd like to see most. Turbo, Vtec, k-swap. All in good time!

@sandeepsreehari5028 7 лет назад

Hey dude... you did a nice job explaining about intercoolers. I have a 2011 VW Jetta 2.0 TDI. Diesel engine. what type of intercooler is it? Air to air or air to water? And please give me a few points about how to keep the turbo cool even if I drive at high RPMs. like around 3000 rpm. Thank you.

@pr0jectSkyneT 7 лет назад

Hi Jason. Which woud you recommend if they are at the same price and size: the Bar & Plate or Tube & Fin?

@GnarlyBlade 5 лет назад

How do I pick the correct size of intercooler for my application? I know I need a 3" inlet/outlet for piping. I'm shooting for ~800HP max. I used flow rates to determine my piping size.

@cirotrinchese4926 Год назад

My congratulations for the explaination. Very cleaner and friendly. A curosity, what is the flowrate and velocity (average value) of ambient air that crosses the intercooler to cool the compressed air? Thank you.

@Spaghetti989 10 лет назад

How do you balance the pressure drop vs extra cooling in the two types of intercoolers? Are there specifications when you buy an intercooler to decide between bar&plate vs tube&fin to allow you to see what will give you the greatest molar flow of oxygen?

@pedr0g0mes1 9 лет назад

hello matte, just one more stone on the grave, maybe some kind of paint or maybe rough sanding on the intercooler could make the heat transfer better due to increase surface area? could the results shown by migthycarmods be caused by the increase in that contact area?

@nicolasbango221 9 лет назад

i see alot of the cons were losses in air pressure. will these decreases in air pressure effect how quickly, and how effectively your turbo spools? So to say if you have greater airpressure, will your turbo spool quick with more power? ( I'm new to the forced induction world lol)

@llv32_yere64 7 лет назад

Hey man, greetings from diesel enthusiast from Finland! I'd like to suggest a video topic: Make video about pro's and con's about water-to-air-intercooler vs. (normal) air-to-air-intercooler. Many vehicles that i've been working on have small engine bay, and it would be super great if you could do a video, where you put both water-to-air and air-to-air intercoolers on test. Just a suggestion thou! But i've seen lots of drag cars that use water-to-air intercooler method, and it would be cool if a wise guy like you could explain in a video about the differences of these two! I hope you read this message and even reconsider doing that kind of video! Thumbs up people if you agree with me!

@EugeneCapeder 4 года назад

@calvinchai8455 5 лет назад

Is it possible to run high-density polyethylene plastic as intercooler piping versus the typical aluminum polish? I know composite intakes exist, but wanted to know your opinion specifically with intercooler pipes.

If you have a cold air intake with a heat shield do u recommend having one of these because cold air intakes are meant to keep the air cold right.

@brianwiththechaser9886 8 лет назад

i had a side mount intercooler witch wasnt that big on a mk4 jetta 1.8t switched to a pretty large fmic getting a few funky problems like car running lean or too much un metered air could this be caused by the new intercooler being so big?? awesome vids btw !!

@joebob502 7 лет назад

With the air-to-water system, using ice, is there an issue with condensation? It would seem that condensation would form thus allowing water droplets to enter the throttle body. If so, would this affect combustion?

@untasnaz 7 лет назад

Do you have any thoughts on turbo blankets? I've heard both sides but I would love your take on it.

@DanielKnocker 10 лет назад

great video man, one question you said that air to air has less of a pressure loss because it has a greater length to travel to reach the engine, does this mean that top mount intercoolers would't have the this problem? thanks

@geordanwilliamson5069 8 лет назад

Is there any set up of taking the AC and fixing an intercooler behind the evaporator to have just that much more cooling? Or would the power being taken up by the AC compressor negate the power gained?

@scugglebottom 4 года назад

how does the number of passes (single vs double) in the intercooler affect best design solution? Is it purely pressure drop?

@dfqnexxus3710 5 лет назад

So here is my question , I have a 2014 Volkswagen passat 1.8L I'm going to upgrade the intercooler, I use the car for driving daily ...which one should i use ?front mount intercooler similar to the one you holding on this video or just an upgrade that comes between the radiator and ac condenser ?

@TheSubienatic 10 лет назад

Hi, I like your videos and I have singed up to your channel I also have subaru wrx, does the size of the intercooler to make the car run cooler or a stock intercooler is better than an aftermarket, it would cool if you made a quick video on that subject. Thank you.

@tb303wpf1 2 года назад

@Silver17dragon 10 лет назад

Hey man ,, thanks alot for these video , they are very awesome and helpful , I feel like your channel is tailor made for car enthusiats like me ,, however I do have 1 question ,, your saying that the air gets compressed by the turbo then it passes through the intercooler ? so air filter then turbo then intercooler ? is this the right order ?

@gwho 4 года назад

does the intercooler use the same body of coolant/antifreeze as the regular engine cooling system? Or do they have separate working fluids / coolants that never mix with each other?

@skatecrete8813 4 года назад

It would be off of the outlet hose of your radiator so youre basically just adding the intercooler in the middle of the outlet line to the engine.

@journeyreuma6990 4 года назад

Do I need to re-tune my engine after an intercooler upgrade? Say 5.5 Depo Beast(stock turbo) on a Focus ST. Stock turbo for at least another year or two. I am running the Ford Racing Performance calibration at the moment. I was hoping that I didn't need to get a tune.

@jayfulf 10 лет назад

I've never actually heard of Yonaka before your videos and after a quick google search they're apparently located in my city

@1431darkblood 5 лет назад

Can I ask a question. Is it bad to have 2 intercooler on my daily? The one behind the radiator, and one behind the lower grill bumpers.

@EngineeringExplained 10 лет назад

If it was oversized, yes, you'd need a larger turbo to compensate.

@kedardesai3469 9 лет назад

Hi , thanks for the video . Very informative. Can you tell me if the bar and plate type intercooler can get clogged with engine oil ? I have blown two turbo hoses and the intercooler is suspected to be blocked . Thanks

@xaytana 9 лет назад

Why would you put oil into the intercooler in the first place? It's not made for oil, at most they're made for coolant.

@donaldkhogan 4 года назад

Thank you for saying "everyone"!! Like every single RU-vidr says "Hey guys" and I'm like wtf? That's only a portion of the audience!

@ctaylor1460 10 лет назад

Given the cooling limitations you point out, is there any reason why intercoolers cannot be designed to exploit the principle of countercurrent exchange? Thanks, good video.
