- Season 3 Episode 7. Jimbo installs an intercooler on the turbocharged Kubota D722 diesel engine in the Saturn coupe. Will the intercooler make a difference? Also Jimbo bumps up the boost from 8 psi to 10 psi... because MOOR BOOST! As a special treat Jimbo compares the Saturn's acceleration to a Trabant that is owned by another youtube creator.
Check out the Aging Wheels episode where the Trabant is tested

great fun with great mileage!
I bet this this can outrun the laws radio . . 😂

I think it's worth stating, lower intake temps will primarily serve to lower egts less than make more power. The intercooler probably gives you more room to increase the fueling before egts get crazy.
Yep. Just fitting an intercooler does nothing more than lower intake and exhaust temps.
Then you increase fuel and turbo pressure until the intercooler doesn't help anymore.
Then you mount a larger one. And then more boost, and then...
This is called the ''more boost'' syndrome. 😂
On 2-stroke race engines it’s 15-20 degrees IAT per jet size. That makes a significant change in power output.
Fuel does need to increase, but lower intake temperatures are the equivalent of more boost.
It's fascinating that so many people know better than Mr Robot, but have zero videos showing off that knowledge.
@@eriklarson9137 not every knowledgeable people can make a good video showing off said knowledge.
@@eriklarson9137 So what you are saying is that.. None of us have any kind of experience with this because we haven't uploaded a video ?
The diesel Saturn is almost matching East German levels of common man performance. I'm intrigued
Iirc the trabant did it's 0-60 run down a highway on ramp, so it had gravity helping.
Since your temp gauge has another spot, you may want to run another thermocouple back to the rear brakes so you can monitor the emergency brake temps. Good work on everything!
lol... yes that would certainly help.
ive watched Rob Dahm build a 2000hp AWD 4 rotor rx7 and i can honestly say im more excited when i see another upload of this little red saturn every week. keep up the good work! you're doing amazing stuff out there!
If the sound of a 3 cylinder diesel interests you more than a 4 rotor Wankel engine then there is something wrong lol. However I know what you mean, Robs car is amazing but his videos are too long for me. I love the 10 minute episodes here and the humour 😊 I think we need an update on the Gnomes
Dahm is a little too excited to talk about damn near everything.
You should be able to add a smidge more fuel with the lower intake temps. Colder air is more dense than hot air and all of that.
Until he turned the boost up the egt warning was still coming on so its a balance.
@@ElPants21 he just added intercooler and made a cut, but didn't install a scoop. Colder, denser air - profit.
He can add more than a smidge.
@@ElPants21 fuel is cooling
running lean is hot and rich is cool
@@danhard8440 in a gas engine, somewhat yes. In a diesel, no
Your microphone quality is impressive
his whole production quality is impressive for someone sticking lawnmower engines in a piece of shit car
One of the early videos he shows his setup. Apparently an old cheap PC and a 20$ USB microphone.
The WRX hood scoop has been shown to flow backwards at higher speeds. Generally, your engine bay ends up being a high pressure area. A forwards facing scoop means you don't have much delta in pressure across the top mounted intercooler. Now, your front bumper block will change the flow/pressure characteristics but the important thing is to maximize the pressure and temp deltas across your IC. Like many of the high performance WRX builds which kept their TMIC you likely want to go for a reverse scoop setup. - Additionally, the lack of a belly pan will alter your engine bay airflow and pressure characteristics. Typically, in a negative way. Plus there's additional aero drag from the aerodynamically dirtiest part of the car (the underside). Likely an easy way to make multiple improvements. The guides on ecomodder can be helpful. Same for tuft-testing the airflow around that TMIC which is a great way of showing your airflow patterns at various speeds. --- Keep up the very interesting work!
Came here for this. Make a scoop that looks like the old Camero cold air induction that faces the window. After about 35 MPH the air over the hood will get pushed down that intercooler.
Louvres would work for this purpose then and he wouldn't have to change his aero at all that way. As was discussed at length in his aero mod video, it's hard to modify the aero on a slippery car like the SC and actually improve it. Louvre the existing piece and weld it back into place if you're going to go that route IMO.
Just move it to FMIC.

Aging Wheels is a great channel. Robert does some really interesting things, and his sense of humor is awesome. This has been a very interesting project, keep the videos coming. 👍
I am glad that two of my favorite channels are at least aware of each other. I was hoping for an actual collaboration!
I like how you call out the viewers. There are wayyyyyy to many "experts" on you tube comments.
Can't get enough of this series
You should for sure add a small WRX style hood scoop, it might not be your "style," but I think it would look cool and increase the efficiency of that. You could also add some little pieces of plastic inside to guide the air directly atop the intercooler. I do recommend adding a little more fuel now, I think that engine can handle it. Then again, I feel like swapping that engine into the insight would be ideal at this point.
NACA duct! :)
If he does that it will add at least 40hp at the rear wheels and almost certainly get him a girlfriend.
@@jerbear7952 what a stupid fucking comment and not at all what I was saying
@@jerbear7952read all the comments.
You win.
Agreed. Hoods are made for air to go over the car, scoops are made to pull it in. Without a scoop, he should at least add 2 6-inch computer fans to pull air though the intercooler. Otherwise he’s just slowing down compressed air from the turbo.
It's actually very impressive to see how much that mini refridgerator unit diesel engine survive so much load and modification. Clearly the Japanese make good engines. Jimbo, love the content. Good stuff. This is what the internet was meant for, I think.
Thanks ! Yes, this little engine seems to be holding up well with an estimated power increase of 50%. I'm not sure how many other viewers actually realize that.

I'm still amazed at how you can finish (and we all know what the word finish implies for a project car) one project and then immediately jump onto another
Oh boy!!! I got my coffee fixed and now going to sit on the back porch while everybody is asleep and get to watch another episode of the coolest project on youtube! Hopefully you will continue to make the neccesary supporting mods and keep bumping the power up Gale Banks style! Lets see what you can get out of that little Kubota!! Thanks Jimbo!

Wow... that Renault looks to be in amazing condition 😮
its nice to see how little power you really need to counter coefficient drag unlike what car sellers would have you believe
True, but keep in mind this car is driven on flat roads. Once you start climbing hills thats when you need a lot more power.

On the 7.3 diesel the cold side of the intake from the cooler is wrapped with insulation tape from the factory to not reabsorb heat from under the hood
I did not expect the Aging Wheels crossover today, but here we are!!
Some more test ideas. Attach some streamers around the hood hole/intercooler, I wager air is coming out not into the hole/intercooler. That tube and fin intercooler needs airflow across the core. A bar and plate style core would be better suited for that style as its much better at passively rejecting heat since your hood is vented allowing air out. Plus less pressure drop across the core with bar and plate. (not sure where your measuring boost from). in order for a hood sccop to actually work and create a high pressure area to promote flow. the underhood area would need to be low pressure so blocking the grill may be benefitial in that scenario. Happy testing!
Guessing the air direction is tough because right in front of the windshield tends to be a high pressure area, but so does the engine bay. I'd wager not much air is moving at all and it really needs a scoop and some simple ducting
@robert rochacz easy to see with some sticky notes or paper ribbons with tape. I would have probably suggested to have the scoop exit air instead of force it in the hood, but that could be an issue if the engine ever has a problem (smoke). So forced in is the only way, or close up the bonnet again, and use case fans.
@robert rochacz yeah Subaru has a shroud on the hood that seals to the intercooler and deliberately open space around the transmission and firewall to allow air to go down unfer the car. The air flowing under the car and seal from the scope to intercooler really aids pulling air through the intercooler.
Raising the cooler up into the cut out and sealing it to the hood might be a simple way to improve its function. Blocking off more of the front of the car should lower the pressure under the hood and might make it try and draw more through the hood also.
Fascinating engineering. The epic struggle of man vs. technology!
Maybe instead of a hood scoop, you could use a naca duct.
Sure you may have some hot air going through the intercooler, but it's at least a forced. Cooling setup
You should do an end of season episode where you have someone interview all the neighbors in the area and see what they think of the crazy guy hotrodding a saturn and a honda insight. That would be interesting. On another note, i truly enjoy all of the engineering and experimentation you do.
Honestly one of the best series on TH-cam.
I'm normally not one to get bothered (anymore) by a missing screw like at 4:55, but it did make my day brighter
Really enjoy the Saturn Diesel Videos. I hope the car does not end up scrapped. It would make someone a great little commuter car. Looking forward to the next adjustments. Thanks for the videos.
Like many others have said, cooler intake doesn't mean more power until you tune for it. Otherwise it's like putting high octane in my knock sensorless car - Unless I optimise the timing, all I'm doing is burning more money per mile.
That's really not how diesels work.
We stopped using the parking brake 30 years ago, because when you live in the snow, if you set your parking brake, there’s a good chance that the cable will freeze, then you have to climb under the car with a hairdryer in order to get it unfrozen!
This is what I love to watch on utube. A guy who is doing cool things and documenting what he does.
Great to see you referencing aging wheels! I love his channel too! Yours and his are 2 channels I've watched pretty much the entire back catalogue!
Did not expect a Renault 10 to pop up at the end!
I knew it looked familiar, but I couldn't figure out the model, not quite a Dauphine, not exactly an R8, an R10 indeed!
Another way to optimize the hole in the hood for the intercooler is to extend the vertical cuts and bend the leading edge of the hole down into the engine bay. The boundary layer of the air on the hood will better follow that path and get more air into the engine bay and over the intercooler. As you said, a scoop is better but until then this is a simple way to improve the hole as-is. Right now most the air is flying over half the opening of the hole and missing the intercooler, the benefit you are seeing is just allowing the surrounding cooler air into the lower pressure area in the hood.
congrats on the 31.97! Thats a big step up from you started. Now that the temp is under control, the next logical step is to increase the length of the fuel rack.

You have so much more discipline than I do with my projects. I would already have wired the waste gate shut, cranked up the fuel and as they say here in western NC “let’r eat”😂😂
All the hugs! So here for this! We have all needed more hugs and love during these times, and it has just really proven to bring our family closer together. Our son says he is the cheese in the sandwich, and that my husband and I are the bread! If someone is having a tough time, inevitably someone says - sandwich time! - and we all get together for a hug.
This is for when families start traveling again. When my kids were little and we were traveling, I’d alway have them pick out some postcards along the way. (I purchased postcard stamps before the trip too.) Then when we were at a restaurant waiting for our meal, it was a great time for them to jot a quick note to grandparents or family back home or even a note to themselves!

You and aging wheels are two of my FAVS!!!! Love all the content, especially the insight, since I own a swapped turbo one!
I have a Kubota tractor with the d720 engine and I in the process of adding a turbo. Your videos are very helpful, thanks for all the work.
This is literally the only TH-cam channel I’m excited for upcoming episodes
Keep it up it awesome
It looks to me that one of those plastic newspaper boxes that attach to your mailbox would be about the ideal size for a hood scoop lol.
These videos are ridiculous. And I love every moment. Good job man.
Something I learned as I am messing with my first diesel, fuel makes more power- and that's the only thing that makes more power. More boost or colder Temps only reduce smoke, or let you add more fuel.
Add fuel till it smokes, add air till it stops, repeat until something blows up.
Oh come on, i was expecting harp sounds when you touched the intercooler 😂
To your credit this is probably the fastest diesel swapped Saturn on the internet and quite possibly the only diesel swapped Saturn on the internet. I think a call to Guinness World Records needs to be made.
Yes, I believe you are correct, this is the fastest diesel Saturn on the internet....
@@robotcantina8957 I love seeing these industrial motors being put to the test in an application they were never intended for. Moving a car with a 200cc motor at highway speeds is very impressive.

I love that you mention Subaru using top mount intercoolers in their WRX and then show a Forester.
Subaru still uses top mounts in their new cars, they just have a duct from the grill to the TMIC.
The intercooler will give you more overhead on how much fuel you can put in it. It should help you keep the engine from melting down from extreme egts
I love the intense sound effect "BIG BLOCK" bit
My OCD thanks you for adding that screw.
I love that insignificant results are also shared here. Real science.
The screw made me chuckle.
The reason for top mount intercooler is to avoid rocks from making holes in intercooler.
Keep up the good work! This channel is as entertaining as Top Gear, but much more informative.
The music is back 😊 glad to see this still in action
I would have thought the intercooler would have made a big difference since manufacturers that save money where ever they can uses them. Maybe you have a point-warm days with high under hood temps might show a benefit. Especially with a couple of catalytic converters hanging on the exhaust manifolds heating the sheet out of the engine compartment.
Thanks for sharing the video sir!
you knocked off 3 seconds to 60 with 3 more pounds of boost - Not to shabby 🙂
Can we all appreciate the 10psi 0-60 test and the fact that that little diesel sounded more like a mini powerstroke... spooling like a turbodiesel should!
I couldn't hear it over the wheel bearing drone🤦
Your show is the most anticipated show I wait for👍😸
Freaking awesome! Love seeing the youtubers I follow working together! ♥
It'd all about how you have the air flowing (THREW) you rinter cooler right now you have air going across it rendering it almost useless. You need to put it face on with the air or make a ram fir it to be useful
Once the Saturn can match the Trabant, you should see if you can convince him to take a break and meet you at a drag strip.
I'm loving the turbo diesel goodness. With the lower intake temperature (and presumably lower EGT), you should be able to add more fuel for Moe Powah! 😛
Hey Jimbo, enjoying your toying around as usual! Any ideas on how to advance the timing on that injection pump? I know literally nothing about that engine or pump beyond what you'd already stated regarding its use... Feel like if you could get the injection advanced, coupled with the turbo and cooler induction, you should see some pretty big gains out of that little guy!
The injection pump timing can be changed by removing a shim that fits between the engine block and the injector pump. We do plan on doing this soon.

Definitely add a scoop. Mount it "backwards" as a previous comment suggested. Make a seal from the hood to the top of the intercooler. Air will then be pulled through the intercooler from under it. Enjoy the lower temps. Add more fuel and boost thus rapidly decreasing the time it will take to reach full destruction!!
Toyota's KD series diesel engines used in a variety of their cars including the Hilux uses this intercooler setup, it is mounted on top of the engine with a small scoop on the bonnet.
Well Jimbo I'm sure glad you pointed out that the temp probe wire was being installed the lazy man's way, after you were done I thought what Derek Bieri from Vice Grip Garage says - "It looks factory..." Interesting results with the intercooler!
The cross-over I never knew I needed - until NOW!!!! : )
More boost next time please! Looking forward to more episodes on this plucky Saturn!

YOU NEED TO START FLAT FOOT SHIFTING THAT THING! DRIVE ANGRY!! LOL
There is a risk that your intercooler becomes "interwarmer", as hi pressure air from your front dam enters engine compartment, and escapes through scoop. OEM's usually mount intercooler in sandwich with radiator. IC first, then radiator. In this case, I assume that you can do the same and solve two problems: IC will be getting cold air first and radiator will have somewhat less air flow (which would take care of thermostat not being able to regulate). Then pile up more fuel and you will be getting places! P.S. That rear bearing is annoying...we want to hear the turbo! :D Great content!
The Robot Cantina-Aging Wheels crossover episode that I've been hoping for!
I saw someone say renault and I was like "aging wheeeeeeeels!"

For future reference when cutting holes in the hood consider drilling holes at the four corners then cutting while leaving the radius in the corner. Great videos, thanks.
I think the white car in the very end is a Renault... The clue I got was the 3 lug wheels..... the " Le Car " had those. I think ( without googling ) that is a Dauphine...... maybe... Cool vid
Love this series!
It will be interesting to see how far this engine will go. I think, being a diesel, it will take quite a bit. Hopefully it can take around 15psi, doubling it's naturally aspirated output.
At this power level, intercooling just doesn't make a noteable power difference, but as the boost increases it will play more and more of a role. A general rule of thumb I found is ~1% more power for every 10 degrees F. More than anything, the intercooler will lower exhaust temps. Maybe this will allow you to get more aggresive with fueling. Gasoline engines can respond much better to lower temps because of increased ignition timing with lower IAT when octane limited.
Would be interesting to have a instant reading on intake temps. I think it would tell a better story of how the intercooler is doing.
Edit: I see the the lower EGT and added fueling idea has been mentioned a few times!
A rear mounted engine 60s Renault… Oh boy, can’t wait for it!! 🇫🇷
Aligning the front end will lower rolling resistance as well. Under 100hp cars you will notice a difference when you align it!
Love the WRX STI style top mounted intercooler. all u need now is anti-lag (on a diesel?) and water injection.
I watch all of Aging Wheels videos.
Oh my gosh, one time I had trouble getting my Trabant up to speed, I left the parking brake on! Drove it about 36 miles!
I'm interested in that Fine piece of French engineering on the right. I'm wondering what Will you do with it? Also I'm excited to see how a Insight 1.6 diesel Will perform.
great video production, can’t wait till the next video! God bless y’all
You should also try a reverse hood scoop (hole facing backwards)
If the hole in the bumper creates higher than ambient pressure in the engine bay (which is hard to say, aero is fickle), a scoop will only fight the hole in the bumper decreasing air flow through the intercooler.
If the scoop is reversed however, it creates a low pressure area in front of the windscreen, pulling air through the intercooler.
Again, this only works if the bumper hole is indeed increasing the air pressure.
I get genuinely excited when a new video from you comes out!😁
I commented on that video that you 2 should do a collaboration! That wasn't exactly what I had in mind but we're getting closer!😂
Hey Jimbo, love the antique tape measure in the beginning, hahaha. Scoop, scoop, scoop!!! By now you guys know I love these videos, keep it up Jimbo, don't let the trolls bother you this is amazing content, makes my every second Sunday morning. Waiting for the next video, cheers!
Intercoolers really only make a huge difference when you're making big boost. Compressed air creates it's own heat by virtue of the compression - that's what they really help with. Removing any heat added by the turbo itself is only going to be an issue when you've driven the car long enough for the cold side to be heat soaked by the hot side of the compressor - so on short test drives it's nearly a moot point. I'm not saying that the turbo doesn't help with temps either way - just the temps won't be different enough to noticeably help power until your dealing with higher boost numbers.
Gotta get that boost up in the 15 - 20 PSI range, and increase fuel quantity to keep stoichiometric ratios roughly in the right ball park.. Beyond that - well, nitro injection, if you're crazy. Which this channel sometimes is. Good luck!
I don't know how much an intercooler will help but there is a chance that the lower intake temps will help cool the rings a bit better so you can push more power without having to teardown the motor and regap the rings. I think everything in the motor can handle more boost fine but i think the ring gaps will be your bottleneck. Also we like the project and I would like to see how much power it can make so i think it is a good idea to regap the rings to a big gap so you can try pushing some insane boost numbers without destroying the bores.
@Tap_profile564 lmaoo not even the right name, shutup
I reckon a mailbox mounted to the hood would make a great looking hood scoop.
Also, anyone not subscribed to aging wheels needs to do some serious evaluation of their life choices.
Can’t wait to see how the Renault runs. What happened to the tires?
I'd suggest you try an air-to-water cooler, at least this way you can dump the heat from the charged air into the cooling system to warm the engine block quicker.
another thing I wanted to, but never tried on my Diesel Volkswagen was installing electric heaters in the cooling hoses.
Couple things, the intercooler also increases intake volume and on small turbo engines intake volume will help. Try testing with the bumper cover in place as well. The bumper cover will lower the engine bay pressure and create a larger pressure delta across the intercooler increasing effectiveness. Tie strings to the intercooler and you can watch the flow.
May I suggest taping some yarn to your hood scoop to see if air is coming in or going out of it? With the front grill open you might just be blasting air out of the top of the hood
Oh wow! A Renault 10! Can't wait to see what Jimbo has planned for it!
Awesome video!!! I have always wanted to do this on a small Kubota diesel! Maybe you can get a horsepower measurment by measuring the acceleration and deceleration of say 30 to 35 mph and taking the weight of the car into account and running the numbers...but i bet there is a phone app that will do that now using gps for speed tracking. duh! lol. I am curious as to what the delta T is across your intercooler with the boost turned up higher. As the boost increases you will find the the compressor discharge temp will increase as well thus making the aftercooler more effective at keeping the intake charge down to improve air density and keep exhaust temps down. I have found that adding an aftercooler on a turbo system will will usually increase turbo lag due to the increase in air intake volume and the decrease in exhaust gas temp due to the cooler intake charge. Of course you will need the aftercooler as the boost continues to rise. I bet since the engine was not overfueling at the lower boost setting you will probably see a slight decrease in power and fuel economy at the higher boost setting due to the higher back pressure required to drive the turbo. You could verify this by measuring your exhaust back pressure before the turbo and your boost pressure at the intake manifold. Your turbo setup is better and more efficient when your back pressure is lower than your intake pressure. When you get into the higher H.P. levels do you plan on dropping the compression ratio to keep your peek cylinder pressures down? I figure if you drop the compression a few points and install piston cooling jets and an oil cooler the the little diesel to keep the temps down you will be able to make it live at the higher h.p. levels. It would be cool to set up a compound turbo system using three of those little turbos once you exceed what the single turbo can do. Have two in parallel discharging into the intake of the single turbo that is currently installed. It would be cool to put an intercooler between the turbo stages to further improve your efficiency and reduce the stress on the turbos. Maybe once you exceed the capacity of the stock injector pump and injectors you could convert it to electronic and common rail fuel injection. I know that might be a little more difficult since this is a pre chamber engine. Maybe a machinst guro on here might be able to come up with something. It would be so cool to see that car get 50-60 mpg and perform like the original gas powered version did and live. I cant wait for your next episode!
