S3 E12. Testing different modifications to the intercooler on the Kubota turbo diesel Saturn.

[@evil_me]

The intercooler is to lower intake temperature, that in return lowers the EGT on a diesel it allows you to add more fuel. So it's not going to directly make power but it will allow you to make more power by the ability to add more fuel.

[@squeakers27]

Exactly so ADD MORE FUEL and then you get your POWERRRR in this 3 cylinder turbo charged diesel lawnmower go kart Saturn coupe

[@otosere2857]

Also, this engine was designed to run at 75% rpm under hard load for long periods. What they are doing here could be improved with a different cam. I really like the work they do---thorough and technical. Top Notch!

[@butstough]

@@otosere2857 they could try to advance the injection pump by a gear tooth, although thats sketchy and imprecise

[@bertgrau3934]

​@@butstough They did advance the fuel timing already, they also increased the fuel pressure. To the point they don't want to burn the engine down. And it did help the power. I assume they don't want to ruin the engine just because they can. I think they want as much power and fuel mileage as they can get without hurting the engine.

Yeah, I do kinda feel we've been here before with this. Expecting a performance boost without tuning to take advantage of the performance boost enabling tweak is.... Optimistic.

Try a water spray/mist on the intercooler like on some Subarus. Can be done with the windscreen washer parts so basically free

[@G1Z1]

The intercooler probably does its job like its supposed to, but you'll need more fuel to compensate for the increased air density

[@KI4HOK]

Came here to say this!! Cooler intake air means cooler turbine inlet temps.

[@averyalexander2303]

Yes, but adding more fuel would probably make more power anyways, of course at the cost of less efficiency and higher EGTs. I suppose adjusting the fuel settings to maintain the same air/fuel ratio with and without the intercooler and, if necessary, adjusting the boost for the same manifold pressure to compensate for the pressure drop through the intercooler would be the most fair way to do the test.

[@mommapanda5736]

@@averyalexander2303 good comments here.

[@G1Z1]

@@averyalexander2303 Completely true! The intercooler also increased the amount of turbo lag the system has, so more boost to compensate for pressure loss and volume increase is only fair

[@KagoK]

The point isn't more power, though. The turbo exists just to keep the temperature inside the engine down, so adding more fuel would be counterproductive

[@chucksherron]

Cooler intake temperatures don't make power by themselves. You need more fuel to take advantage of the denser air.

[@RickvandeS]

If you really don't want the hood scoop, you could try using something like those flexible dryer ducts to scoop up the air at the front bumper towards the underside of the intercooler. The spacing might've just created enough space to do it. It would make plan C work better I think. I also think it needs more fuel to really benefit from the denser air. Thanks for the fun experiment!

[@someonesomewheresomdeday]

[@anthonyshaw9383]

Like others have said, the idea of an intercooler on a diesel is to lower egt. This, in turn, could be used to add more fuel for better performance or to use as a safety buffer for egt. I actually like the foward facing scoop as it is reminiscent of the WRX.

[@crackedemerald4930]

I think you could install the fans over the intercooler without turning them on to see which way the airflow makes them rotate

[@alskjflaksjdflakjdf]

I'd be curious to see this as well. My guess is air is getting sucked downwards because of the air dam installed on the front of the car results in less air under the car, but my intuition could be wrong. I thought the sideways scoop would work better than it did. :)

[@HamRadio200]

With intake temps of around 120F, there won't be too much gain with an intercooler. However, if you are able to run significantly higher boost pressures the temps will be much much higher, and inter cooling becomes an advantage. My Cummins 6.7, stock fuel settings at 40+ PSI boost will run in excess of 300+ degrees on the compressor side. The intercooler will drop the temp to around 20-40 degrees above ambient temp. That's a huge improvement.

[@terminallygray]

I believe that you are forgetting the biggest benefit of using the intercooler>>> decreasing the exhaust gas temperature !!! And when that happened, you were tickled pink about it and glad it improved the chance of solving that problem. It also helped to increase the boost from the turbo. Just a friendly reminder from a follower of this project. I like it a lot and wish there were more people on youtube that did these type of things.😃👍 And (of course) installing the fans to pull air into the intercooler from under the ram air scoop is the way to go (puller fans). There may be some benefit from reversing the fans (pusher fans) and trying the cowl induction scoop again, but you have the final say on that. It's your experiment and video series.

[@MichaelJordan-jv6ic]

One thing that can help the intercooler cool even more is using cast aluminum pipe on the HOT side. I discovered this inadvertently when I was modernizing the intercooler pipe on my 1990 Dodge Cummins (It actually has an old, factory-fit Banks intercooler!). The only pipe piece that I could find for my 3" dia., 6"-long 45 deg. bend requirement was in cast aluminum. As we all know, aluminum dissipates heat, and I can definitely feel the heat coming off of this piece of pipe before the air even gets into the intercooler.

On a hot summer day with 15lbs of boost, I have had IAT in the 180°s pre intercooler. Most of the boats I work on that get run hard have twin 24l v12 diesels with a tripple turbo settup.

Not to mention (dead horse) you would be installing plastic fans over the hottest part of the engine. Plus, the hood scoop looks fuggin' rad! Love the content RC crew, thanks so much for making it!

[@tihzho]

The ram air scoop needs to have a higher profile to get into the airstream. Try taping short lengths of yarn on the hood to visualize the air flow.

[@drippingwax]

Tuft-testing is always good, but this is how car manufacturers have done it for decades, and it is appropriate for much-larger engines than this. It would take longer to test than to implement and his regular camera setup would work. Someone suggested tuft-testing to see which way the air is flowing on the intercooler, but since the scoop worked best facing forward, arguably the air is flowing down.

[@tihzho]

Cowl induction works because the engine creates more negative pressure than the air around the hood. In this application, there's actually positive pressure below the intercooler, and that's actually drawing air in through the grille, which is being heated up in the engine bay and exhausted through the reverse-facing hood scoop.

“Spring is the time of plans and projects.”

[@TykeMison_]

Optimizing the turbo temp isn't just about possible power output, but the intake air temp directly correlates with the exhaust temperature. That 50F reduction helped EGTs. I'm sure optimizing the temperature for another, I'd hazard a guess, 15-20F maximum, won't mean much of anything, but the input>output relationship of an intercooler isn't so simple anyways. Higher loads, and higher ambients, will allow the intercooler to dump more waste heat (up to it's thermal equilibirum limit). Just for easy example, that 50F during colder times might be as much as 75F during the height of Summer. An optimized placement, heat shielding, airflow and routing might allow 100F or more turbo out > intercooler >intake in reduction. This would make a vast difference during a 95F day as compared to a 60F day. The absolute temperatures matter just as much as the power density gained, and the absolute temperatures have an effect on part lifespans as well. Just my two cents.

Glue a small freezer to the rear deck lid, modify a weed-eater so that it pumps water (roof mount the pumping system), and then mount the intercooler inside of a large hood-mounted ice chest.

[@antoniovillanueva308]

Wiper-mounted dual intercoolers is also something that seems feasible.

[@IstasPumaNevada]

Having seen wind-tunnel test results, cfd simulations, and testing from lots of people obsessed with fuel economy, I've learned that there's an area of high pressure on the hood just in front of the windshield when the car is moving at speed, and that if there's just a hole in the middle or back of the hood, air tends to flow down into the engine bay rather than up out of it. This makes me believe that without any scoop in place, the air was pushing down through the intercooler instead of up through it. So I predict that with no air scoop, the fans pulling air down will be more effective than the ones pushing air up out of the engine bay. Or it'll be too small an effect for you to measure reliably.

[@PsRohrbaugh]

The necessity of an intercooler is directly proportional to how much boost you make, thanks to the ideal gas law / adiabatic heating. If you were running the boost seen on some engines (2-4 bar or 30-60 psi) the air would become significantly hotter than ambient simply from being compressed in the turbo. But you're not even breaking 1 atmosphere, so there's very little heat generated. There's still unwanted heat, both from the turbo housing and the compression you are doing, but the intercooler isn't nearly as important as if you cranked up to boost. So don't worry about the intercooler unless you plan on cranking the boost. This will be a much more important at 30 psi.

The fun thing is that the air isn't being drawn into the hood scoop, it's being pulled out. The high pressure area right outside of the scoop is forcing the low pressure air inside the engine bay to move out. Cowl induction is just that, induction. Meant to create a low pressure differential area for a NA engine to pull cooler air from. But I'm here for watching you attach PC fans to a car.

If you want airflow across a radiator you need to have an effective pressure difference across it. As is, the hood hole will likely act as an air outlet since its in a low pressure zone and you are probably allowing more than stock pressure build up in the engine bay past that small radiator (if you haven't shrouded it that is). Closing off the intake hole a bit might make the ram air setup more efficient (and the other radiator too). Enough regurgitating Julien Edgar knowledge for now, am enjoying your series a lot so far.

[@Madnessnunky]

I think it'd help to put some adhesive foam around the intercooler to force the air that enters it directly through to the hole in the hood. It'd basically be like ducting. I have an old Corvette that has foam like that under the hood to ensure air goes through the radiator and not around/over it instead. I'd expect it to make zero real world difference but ensuring the air you do get is forced through the intercooler would at least be a nice "fit and finish" aspect to the design.

Heating the intake air makes sense given that diesels use the heat of compression to ignite the fuel, so starting from a higher initial temp just raises the final temp a few degrees making ignition more positive.

[@IgnisMan]

[@hayzeproductions7093]

Diesels are reliant on heat, its what makes them operate. During the winter and late fall months I usually unplug the cooling fans on my jetta, seems to drive much better regulating its own operating temp. Sometimes it gets a little too cold down into the 20's that when you stop at a street light, engine temp will drop then the car trips itself into warming back up and the RPM's raise up to try and keep itself warm. I end up loosing fuel mileage keeping the cooling fans plugged in during winter temps. This was an exciting video to see for a new viewer! However I will vouch for that little diesel and say fans or cooling solutions for diesels are not always necessary unless ambient temps are above 75 degrees, or its an engine the size of a Cat C15 doing heavy hauling.

[@blackstorm86]

It makes perfect sense that "plan B" worked so well. You said the intercooler didn't provide any performance increase, but I think you might be overlooking something. I've found that, for every 1 degree decrease in intake temp the exhaust temp also (usually) decreases by 1 degree. You had issues with exhaust temps in previous videos. The ram air scoop decreased intake temps by 13 degrees. Did you notice a corresponding reduction in exhaust temps (Maybe not the full 13 degrees)? That might allow for some adjustment of the injector pump and/or you can push the engine a bit harder on acceleration. The fans should yield similar results as the scoop but I think it goes without saying the pushing air though from the engine bay will increase intake temps. Great videos! I always enjoy seeing what contraption / combination you'll come up with.

Be deliberate “For fast-acting relief, try slowing down.” -Lily Tomlin This simple yet effective calm quote from actress Lily Tomlin is the quick reminder we all need in our lives: that going slow and being deliberate will end up taking us further than rushing about.

Rise and shine “Today start your day with a smile, calmness of mind, coolness of emotions, and a heart filled with gratitude.” -Anonymous Ever heard of first thought, best thought? If you begin to incorporate mindfulness and gratitude practices into your morning routine, you’ll find yourself becoming that much closer to finding the inner peace and strength you desire.

Patience is a virtue “Be patient. Life will offer you another chance as soon as you find calm within, for abundance is born out of calmness.” -Leon Brown Ever feel as though something fell into your lap when you least expected it? That’s often how the world works. Continue to be calm and allow things to come your way in their own time. Simply doing that can open up a universe of possibilities.

Greeting from NE Kansas. You should try to get Gale Banks to give you some input. He's a legend in engine performance, especially turbo-diesels. I bet he could set the record straight whether or not this engine benefits from the intercooler in some way other than performance numbers.

Your channel is great and inspiring. Its so cool to put a small diesel engine into an cheap and ugly car. My son doesn´t understand. Guess 32 years is way too young to feel the magnificence of your work.

I love how many people are saying you need to add more fuel, when the point is to lower exhaust temperature.

[@MsJon52]

got to love a hood scoop, plus fans to-boot, your gota put a fiber glass super scoop on, oh yes you're scrapping the car, hopefully on another future project then,thoughrouly enjoyed this series.

Most of the suggestions I had were actually covered in this video so I’d say you’re on the right path with your train of thought, or at least the same one I have. I think the additional volume you’d have to compress to mount the IC all the way up at the bumper would actually hurt performance so leaving it in a direct line to the intake is a good call, if the object was to test the effects of engine inlet air temperature, you could use an air to water cooler and use chilled ice water in your water tank like a lot of drag and sled pulling guys do, or if you had enough boost to get the air hot which it doesn’t really seem to look like it, you could cool the water for the intercooler with a radiator mounted where everyone is saying to put the intercooler and the air to water system wouldn’t add much volume if any to the air between the compressor and intake, I think that fact is overlooked by the people suggesting to mount the IC at the bumper.

I honestly love how the ram air scoop looks (in theorey, I'm trying to imagine a more proper-looking setup haha). Reminds me of those cool little kei cars with top mounted intercoolers and tiny off-center hood scoops

The reverse cowl only works if you have a full flat bottom. That way it pushes air through the bumper and forces it up and put instead of allowing it to escape you the bottom. That in combination with air passing over the scoop at speed creates a vacuum effect to help drawl air out of the engine bay. The problem is, this will only be a benefit at speed. So without a cooling fan pulling air into the bay through the bumper, you'll continue to climb in temp at low to no speed. However, ducting really plays a huge part in this. Forcing all the air from the bumper into the engine bay with good ducting plays a bigger part in the cooling effect than you might think. Cardboard and duct tape molded to the shape of the hole in the bumper as a duct between the bumper and bay will drop more degrees than most combinations.

I keep asking him to do a full stealth belly pan, but no!

[@faitkeeper]

@@drippingwax I remember seeing that mentioned on the last video. Odds are he's gonna have to step up to it.

[@branemadder]

I love how you use a nice mix of incredibly well thought out and engineered solutions alongside wing and a prayer bubba duct tape testing. No where else can I find this!
