I see your point but my boost gauge dropped 5 psi. Looked further into the cause and found my collector pipe to the turbo let go on the turbo but otherwise never knew I had a problem. 19 psi to 14 psi was a big difference but did'nt feel the difference until it was fixed. Happened so gradually until 1 day I said to myself......self....something is not right here. Happened on my 7.3 powerstroke. It can still be used as a good measuring tool.

[@larrygrogan4408]

I see it being useful, but I also see it being useless. Certain programs trick the ECU in to using an altered boost number. If you are obtaining the boost number via the ECU then the information displayed is probably inaccurate. I would prefer to see what the ECU is being told the boost is and also pull real data and display the actual boost being administered, but at some point you run out of data to display on a unit such as the live wire plus. Obviously each motor has different values of interest. I would prefer to monitor fuel pressure and degas pressure before I would concern myself with MAD or whatever it was he called it. In my mind my intercooler is not going to change what it does mid drive and I can not control; ambient temperature, air density, or humidity. I can however control how much boost I am pushing and would prefer to see the boost scenarios my right foot and gear selection are creating. Now if you were going to fog the intercooler, then maybe this would be good info display, but it seems you could simply display MAF data...

[@Dieseldickrick]

I feel like this was just stating the obvious, no one was ever disputing any of what he said. Cool to see, but it’s been intuitive to understand for a very long time. That’s why manufacturers started inter cooling....

[@blow0me]

If the video had been maybe 30+ years ago, it might have been news. But the video is purely to advertise the product he is selling, nothing more and as you say, the detail is all basic common sense. And his MAD is pretty much the MAF almost all OEM's use anyway, some of which dont even take boost into consideration.

Thanks Gale Banks for a well presented video. I saw a GE portable high wattage electric generator setup. It consisted of two full sized truck trailers. One trailer carried the generator and a full size turbine. A turbine is a jet engine tuned for torque. The second trailer carried an intake air chiller. They claimed that by using some of the generator output to run the chiller, total electric output of the system increased. This agrees with everything Gale Banks said. With a completely different style of engine. Good work.

Exactly right! There is alot more to making power than boost percentage. People forget about things like speed velocity, density, air temp, resistance and flow of cylinder heads, valve lift vs duration, etc..etc..

[@sethalton205]

While the boost gauge isn't great for tuning, it is a great way to identify if your vehicle falls outside of expected tolerances. If you're over-boosting, you know that something is wrong with the wastegate operation. If you're under-boosting, that's a sign that you have a boost leak :D

[@cassiuspuckett8789]

Wow Mr. Banks!!! That was amazing!!! I knew cooling the air would make a difference in the air density and you would make more horsepower, but wow, that was a major difference from not cooling to cooling the air. Amazing test results. Thanks for sharing.....

[@davemcdaniel4856]

Love it! I've been saying for years that boost is just a measurement of restrictions. Better flow with cooler denser air is king.

[@HPFarm]

Love Gale's innovation. Answers the age old question of what's more important boost or air flow, neither its all about getting MAD.

[@RobertBeck-pp2ru]

I understand the air density thing. Was taught that when I learned to fly airplanes. I don't think the boost gauge is dead, as it has alerted me to a pressure leak at the turbo outlet on my '91 Daytona 2.5L . The Idash is the cats ass for seeing the entire picture. Am seriously considering the purchase. Just need to know more details about fitment and sensors.

[@BluesyBor]

I doubt any sane person uses boost gauge as an engine performance data. It's role is to tell the user if the charger performs as intended, is it making enough manifold pressure and not more, because both situations are signing a problem potentially leading even to engine's destruction. It's just the simplest way to know there are no immediate major issues with the charged intake while driving.

[@joshbobst1629]

As a former truck driver, I used boost gauges as a rough estimate for how much fuel the engine was using per cycle, and therefore what percent of its rated output it was producing.

boost is great for overcoming intake reversion but unless you could manage to have extremely high pressure waiting for the intake to open and somehow manage to drop the pressure to nothing and still manage to fill the cylinder to get an ice cold intake charge :) (if only our atmosphere was r134)

[@norman_sage2528]

[@Levibetz]

I love this perspective shift, really makes much more sense. I wonder how do turbo dynamics change (or do they) with temperature and humidity. Like does the turbo's compressor map change as air density changes?

[@josephcottone9613]

I didn’t watch this video yet but thank you for making it!!! Psi is just a measure of resistance through the system. People can’t seem to grasp that a bigger turbo will flow more cfm and make more power at a lower psi than a small turbo.

[@ryanmalin]

I knew you were going to talk about manifold air density good work Mr. Banks thank you for sharing your knowledge. You are a legend

[@fordmud]

So this is what I already mostly knew about, but my question is, which I have never tested, can you set the waste gates to adjust for density instead of pressure? Or would the pressure difference needed to compensate for density cause to many other problems when the boost has to rise above what it's normal setting is to compensate for hot and dry air?

[@Ozgrade3]

Very interesting video. We actually use a MAD gauge in aircraft, only we call it Manifold Absolute Pressure.

[@kleetus92]

[@justinphilbin8313]

One question... as a consumer looking to modify a vehicle, especially a diesel, first thing that’s always said is you must have gauges. So your first mods are intake, exhaust, tuner, and gauges. Other than your initial test to make sure you have improved the performance of your truck, what is the purpose of gauges? When using your truck on the daily, you can’t change your environment to anything other than what it already is, and as long as your tuning is good your truck won’t enter a danger zone, so for most of the average Joes I’m not sure where these gauges are helpful.

[@bankspower]

"So long as your tuning is good." How do you know if your tuning is good? This gauge will tell you. How good is that turbo you just bought? The gauge will tell you. Is your intercooler doing anything or is it just a shiny piece of pretty aluminum? This gauge will tell you. What's the point of watching Boost or EGT on a gauge. Can you do anything about boost? Not unless you're a tuner. But you're right. Parameters like Density may not be for everyone. There are 80+ parameters on the iDash for everyone. For this video, rather than focusing on the features that all digital gauges have, we chose to focus on what sets the iDash apart from all others... and that's Density. Along with a few other calculations we're about to bake in. But most importantly, thanks for watching. 👍

[@Catrik]

I'd say this (or these types of) gauges would be pretty good on a daily. Because it's a small and compact gauge you can have it hidden if you dont want to see it but you can still have multiple datas visible on it when you are tuning or checking stuff. It's not even expensive compared to getting many high quality "normal" gauges that only show 1 or 2 data. But it's not for everyone, I don't like the look of it and I like looking at gauges so I would just have mechanical boost and intake temp gauges.

[@kleetus92]

​@@bankspower How are you going to know your tuning is good? I'd hope to God the dyno pull results from the tuner you just spent a couple grand at for starters... And so this gauge is going to differentiate between the infinite list of variables from parts, manufactures, weather conditions, fuel quality and how it's tuned? What's the magic number for MAD? At what RPM? Diesel or Gas? While it's neat to see more blinking lights on the dash, (I'm an engineer myself, I get it), at the end of the day it's just a meaningless uncontrollable number as it's being used as a daily driver. Perhaps with the possible exception you drove through a puddle of concrete and totally clogged the intercooler, and then decided to go drag racing, but I find that scenario rather unlikely in the end.

[@Steve_I]

when I bought my duramax, my first two mods were exhaust and a set of gauges. egt, boost and fuel rail pressure. granted the truck was stock so you don't have to worry as much. but it is nice to keep an eye on those. egts are important to keep an eye on while towing, boost gauge let me know when my power steering line rubbed a hole through the intercooler pipe. I wouldn't have known other wise until it got really bad. and fuel rail pressure let's you keep an eye on the injection pump and the health of the fuel system to an extent. when I watch the rail pressure drop when it should be climbing. that tells me something isn't right, even if its as small as the fuel filter. they get significantly more important once you start tuning and modding tho. at the end of the day, the more things you can monitor the better in my opinion.

[@flinch622]

Intake air temperature affecting hp is something most notice instinctively, but it really is nice to have real numbers. My little old pickup truck generally picks up noticeable horsepower whenever ambient temperature drops below 60F. Never dyno'd it, but it is real and thats using the same grade of fuel. Should we call temperature/humidity corrected numbers Boost Factor to get away from blind reliance on Boost Pressure? What I couldn't say is where to set the benchmark numbers of humidity and temperature to either add or subtract from the pressure number - maybe 100F and 50%?. Some people still like to know boost pressure numbers just to keep tabs on if their wastegate setpoint has drifted [or gone completely pear shaped] and maybe spot other problems. Perhaps one gauge with an over/under display of both numbers is all a driver needs? The rest can be data logged. And... could the next performance step be a variable [computer controlled] wastegate? I would still want something mechanical backing it up as a safety device in event of control failure however - put a sensor in it for the driver to know if it ever trips just in case.

[@jhowe67]

So it's a must have for bracket racers. This way, no matter the track, you can always run at the same power level.

[@njinthemj52]

Well, I'd say for people who don't have an unlimited supply of turbos, the boost gauge can give an early indication of an issue. Combine that with an egt sensor and someone may be able to save their truck before they unknowingly drive it into the ground. IMO having a gauge is never bad, unless you can't trust it.

Great presentation. As always. What you showed is great knowledge. That being said..I don't believe the boost gauge is dead. Most drivers are intercooled and don't have control over humidity. This leaves our variable left to MAP. It's the same principle as to why I dont have an IAT gauge or even a water temp gauge on a pillar. The boost level changes with driving attitude and style. It's what our foot has control over. What did surprise me is that essentially you only gained 10% of your HP from intercooling. And by the look of those EGTs and the sound of surprise in your voice when your turbo supported 600 cranking horses...I think you have more HP to gain just by increasing your CFM numbers. Hm. A CFM efficiency % gauge....

[@chrismonteith1]

Would love to meet mr banks one day. Amazing man. Keep the videos coming! Love them all!

[@ryanbrown918]

I dont think anyone has ever stated that boost level is the ultimate parameter to making power. The same level of boost pressure on different engines can result in a huge amount of power difference. 17psi on a Chevy Cruze (Stock pressure btw) is a whole lot different than 17psi on a Chevy Corvette. It's a measuring tool to base tuning parameters on.

[@Squanchler]

To everyone saying “Duh he’s saying inter coolers are good, everybody knows that.” You missed the point. He’s explaining that measuring the proper variables is more important than just boost pressure, and their product can effectively provide that information.

[@bankspower]

Greg Vinson for President.

[@GNX157]

He doesn't address the delta P across the intercooler, or the relationship of the flow thru the IC versus its resistance to flow as boost increases, and the inherent increase in air temp. When you force air thru an IC you reach a point where it can't flow the air without a drastic increase in resistance, and that causes the air temp to shoot up higher as the turbo works harder and super heats the air to a point you're negating the use of the IC

[@nealarcher1970]

Customer support was no help to me so maybe this is better: Air density consists of 3 different data inputs: air temperature, air humidity, and air pressure. So my question is, without installing a humidity sensor in your intake manifold, how do you accurately record Manifold Air Density? To my current understanding, you can’t take the humidity reading from the air mouse because as soon as the air is heated when it’s compressed and then cooled from the inter cooler, the humidity changes.

[@bankspower]

When you say customer support was no help, does that mean you called or emailed and go no response or was it that you didn't like the response that you received? The relative humidity changes but the mass of water vapor pressure doesn't. We use pressure ratio and ambient vapor pressure to correct for dry air manifold air density. You only need to know relative humidity in one location. So, an AirMouse is all you need to correctly compensate for humidity. The math is handled in the iDash.

[@nealarcher1970]

Banks Power first thank you for the explanation. And when I called, customer support was not trained well enough on their own products to answer my question (that fine, I can understand) so they said they’d call me back. Well they never called me because that’s too much for them too handle. And I sense a little booty tickle coming from Banks Support?

During the process, around video number two, Gale sat down to design one with our engineers. Then, after weeks of fine-tuning, it was tested, perfected and sent to production. We had hoped to share the data about the diff cover testing last September but it didn't make sense to share the info and have our competitors race to market with updated covers. We held onto the info in order to time it with our diff cover launch. We'll only get one opportunity to share the data and we want to make it count.

[@syx3s]

clearly the applications of this module are that you can fuck with your intercooling as well as the rest of the air system and actually see what is happening in the system with each change.

[@BJL2142]

for someone building their own motor and tuning at home, could someone use these to make educated decisions in regards to parts combos, turbo selection and plumbing efficiency? i understand it is not a dyno but by logic a higher MAD equates to more power production provided you have good af/r, engine/oil temp, so you could make a change and take a log to see if things improved or not?

[@kwittnebel]

If you want to do this yourself, you need an AEM dash display and datalogger and a bunch of sensors: pressure, temperature, humidity. They combined three sensors into one. It is easier to spread those around than to put separate temp and pressure sensors everywhere. It has a cool datalogging function, so you don't have to figure out where to mount a screen etc. I was looking hard at a CD5 setup with a 29 channel CAN module by AEM but have to say this little thing can probably do most of what I need for my project. Only thing is, I don't know if it comes with a great data analysis package like the AEM stuff does. And I don't think it will log turbo rpm sensors. Basically this is for guys who want to push more power through the motor and do it in an informed manner.

[@custommotor]

Maybe do a video with restrictors between the turbo and manifold? Show people how X PSI could differ between one motor and another. The restrictors could act like smaller valves.

failed to prove. without the manifold pressure he cannot calculate air density. what intercoolers are those?

[@44hawk28]

So boost is only giving you about 60% of the data you need to extrapolate manifold air density. So you add two more mechanisms to measure humidity and temperature Within manifold air and you will have a gauge that can then be more easily applied to the expectation of power output. Is that not a very simple explanation what is being discussed here?

You been living in a recluse somewhere ? water/methanol injection is huge, and has been for a very long time and there are dozens of suppliers, with tens of thousands of users. It is very common.

As the manifold air density increased did the engine ecu automatically add more fuel to avoid running lean?

[@kleetus92]

It better... that's it's job. It's getting that information from the mass air flow sensor.

[@kwittnebel]

Yes. It would have to.

[@kwittnebel]

That is the whole idea: more air molecules in the cylinder allows you to burn more fuel at the desired stoichiometric air:fuel ratio.

Yes
