80% of the entertaining factor on your videos is the way you narrate. Please do not change.

This is the slowest highly modified car on KZfaq and I love it!

Keep in mind, a one pound improvement in boost to six pounds may not sound like much, but it is a 20% improvement over five pounds of boost. I think the take away for today is that your little Kubota diesel likes boost.

I love how you always add the metric conversions when you mention a unit. Even when the conversion is just "KM" because you said "Let's put some miles on the car."

All I can say is you better keep the gnomes away from Alexa.

The unit conversion just before the road trip was very helpful and the traffic comments had us Virginia residents laughing almost off the couch

Ah rush hour in central Kansas... Brings back memories of being stuck in traffic jams behind a car for several seconds.

“The good news is, I don’t care.” - Jimbo Love it!! 😂

Flashing "KM" on the screen when you say "putting some miles on it" is a nice touch

GLaDOS would have been proud of your, "The cake is lie' reference.

Glados coming fer ya

Glad I always stick around until after the jingle at the end of your videos. 😉

So entertaining! Thanks for all your hard work and editing. I always look forward to your Sunday videos with my coffee and toast.

It's always a pleasure to see a Robot Cantina video hit my subscriber feed. Very rare for me to see this while at 0 views!

Ratman knows about the cake!

I know the intake hose that you are using is *Reinforced* and in theory should work fine, But id like to see how inefficient it is compared to rigid pipe. Of course, you would still use the reinforced flex tubing as couplings at the joints. But i image that the *entire run* of the pressure side being flex tubing is not helping. Its worth a try 😊😊

The kabota must just like 5psi no mater where it came from. I like the speed comparison between cars. Very insightful 😄

Oh Planet Aluminium, that’s where my cousin is from! What a coincidence!

Diesel tuning thoughts. 1. They like a lot of boost. To simplify things, think of it this way. ( this all happens because a diesel runs so far south of stoicometric afr) fuel makes the power. Boost is just to lower egt and smoke to acceptable limits. 18-20 psi is where O.E's start with diesels. Most O.E. stuff is around 30 psi, and the tuner boys get into the hundreds. 2. Your egt limits are low. You could safely use easily at least another 100 deg. C 3. You need to investigate ways of modifying the pump to provide a diffrent fuel curve. You already have more than enough fuel at low rpm, you now need to add fuel only at higher rpm. Currently, the way you increase fuel, increases fueling everywhere, leading to too much smoke and high egt before the engine is really into its stride. 4. This is probably the best thing on KZfaq ❤

I enjoy the purposeful positioning of self-deprecation in these videos. Refining that technique was the key to my survival as a child. Smart kids got no love in the GenX era. Lol

This car deserves a diesel badge. Only 4.5 seconds, that is truly impressive. Great episode again. Thank you!

Love the Karate Kid reference. Cut away anything that's not a pulley.

making a pulley on camera for the first time: I follow a KZfaqr from the UK that moved an entire pipe organ into his workshop. he ditched all the primitive electronics and built his own controllers. The armchair warriors have been telling him "you don't know what you're doing" since day 1 yet he has a playing instrument that was not working when he bought it! And he wrote a song using the words "you don't know what you're doing" that he played on his organ. So, kudos to you for sharing your education and experimenting with us . obligatory "you're doing it wrong." 😊

The effort you put into these videos is mindboggling.

I'm not even a believer, but Sundays are my Robot Cantina worship day! Cheers from Portugal! 🖤

Remember when you had to import aluminium all the way from the UK? That's when the sales of domestic aluminum started taking off

(Napoleon Dynamite voice) This guy has lot's of automotive & machine shop skills. Girls only like guys who have lot's of skills.

The bit at the end was interesting. I didn't realize you were getting so close. Also, the Portal jokes had me rolling on the floor! 🤣🤣

Richard Holdener did a vid on the AMR500 and the most important take away was how incredibly kludged the intake/output manifolds were for it. You might want to look into some 3DP replacements that don't feed that small round hole into the large rectangular port & vice versa; when the supercharger can breathe better, you'll get more boost for the same amount of power taken off the crank...

"the cake is a lie" HA! love it!

You Yankees get all the good stuff! I tried that over here on my side of the pond and Alexa just said "I'm sorry Dave, I'm afraid I can't do that!"

“The cake is a lie.” Outstanding.

9:05 the “km” sent me 😂😂

Love your scientific approach: one thing at a time, record and monitor changes.

I loved the post credits scene.

Well sir I sure am sorry the blower pulley didn’t get you to 10-11psi. I commented on the episode back when you did the crank pulley and shared your loathing and would also have tried the blower pulley first but it was inevitable. Just wait though, 3rd time will be a charm……good luck and great project! But…… you’re going to need intercooling above 6-7psi. Prochargers are about 6-7psi boost blowers and come with an intercooling setup because of this. Your intake temp is climbing noticeably with that 1-1-1/2 psi increaseas you noted. Just remember Boyles law, as pres increases, so does temp.

This really is an exercise in how much you can do with a little engine. I could get back and forth from work on less than a gallon of diesel. Your workmanship looks to be top notch imo.

Ahhh now that’s what we’re talking about 16 seconds in the stock insight! A goal has materialized and the gauntlet slaps the pavement! 🎉

2.28 Seconds Is Very Impressive in fact IN the world Of Drag Racing Thats HUGE Can't wait to see the Crank Pully Test

Oh Jimbo thank you for the surprise benchmark at the end!!! Thanks for the great content RC crew!!!

The portal reference caught me really off guard

Thr output for the supercharger could have a modified flange to make it flow better.

thanks for the miles to km conversion at 9:06

Jimbo. That friend you need who can test and fix any problem you might have. Great work, Jimbo. 👍

Nice! I saw your comment on that other channels supercharger video. Honestly, I was gonna link it to you, but you already were all over it.

I never expected robot cantina to be a Portal game fan. Love it!

I was having a really excellent day recently (A beach holiday with a mate, successful day fishing n boating, watermelon daiquiris as the sun goes down kinda good day), and found myself whistling a happy little ditty. thought you might like to know thats the headspace I associate this channel with. so your doing something right, just thought you might like to know that. also, Kudos to Norma Rockwell for that little ditty, Prizefighter

I can't believe how close the diesel is in matching the performance of a stock one, that's pretty amazing for a fridge motor

I love watching this vehicle progress. The fact that it uses a tiny amount of fuel and can do reasonable speeds is awesome! I'd like to see an intercooler and see what effect that has on performance and fuel economy

"...the good news is 5:28 I don't care...", Brilliant!

Nice new pulley! Looks like the belt will bottom out a bit sooner than the other pulley, but only a future jim problem at most. 🙂 Nice video 👍🤓

I don’t know why I’m always so excited to see the slowest Honda Insight on the planet, but it’s one of my favorites! I’m excited to see what a little more boost will do and what difference an intercooler may or may not result in.

That screw driver was my first project when I was in HS back in the 60's !! LOL

You are fulfilling a long time shade tree mechanical dream. When this chapter is finished think about scavenging the exhaust heat into small steam engine (via dead 2stoke outboard engine?) with pulley to rear wheel… you start my week off with a smile. Enjoy your cleverness .

I had that same supercharger on volvo b230 and i just randomly picked up smaller pulley from tractor parts store and hand filed the groove for the locking piece.

Awesome!! Over 2sec faster!! We can do it! We can make it faster! Break 19 secs!!! WE WANT MORE BOOST!! This project is more addicting than seeing a sports car. More boost! More boost! More boost!

That was fucking AWEsome, shaved 2 second off that joint. We want more Fuel and Air!!! Im excited to see this crank pulley!

Good move using the parting tool to turn the OD - saves time messing around with changing tools👍

Props for the Portal reference lol.

You might be surprised that the biggest performance mod could come from the exhaust. Should try testing with extremely long primarys, same diameter pipe as the exhaust ports, like three, 6ft long or more to target the low rpm torque. Then, merge them into a 2" collector.

Now that you have a benchmark of a stock setup, you have a goal you could go after and dethrone.

A bit of advice for sizing V-belt grooves. The top of the belt should be flush with, or slightly recessed from, the outer most surface of the pulley; but the bottom of the belt should never touch the bottom root of the pulley groove! The V-sides of the belt are what provide the friction and thus driving force for the belt. If the bottom of the belt contacts the root of the pulley it'll probably slip or ruin itself in short order.

As usual, interesting stuff. Supercharged Diesel wasn't really a thing we saw until Jimbo went for it... and the results are interesting. It's getting closer to "city car" performance.

Jimbo, nice job whittling down the aluminum puck into a reasonable pulley. As a bonus, it wobbles much less than an offset vibration weight! The post video stock versus diesel performance test was fairly impressive; not bad for a garden tractor engine retrofit.

They’re talk 2 feet of snow here today so I was hoping for like a…….6 hour video! 🤣

The comedy on this channel is what keeps me coming back. Great episode.

Thanks for the Portal reference 😂

Meanwhile in the news, reports that.. "Millions of peoples Alexas' have been asked to open a portal to a planet Aluminium ..." 😏🤣🤣🤣 😎🇬🇧

Thank you for your unique approach to tinkering with something.

9:04 'Preciate the unit translation, there. We'd have had no idea you were going some distance otherwise! :D

I love the dual language use when ordering the metal for the pulley

I look forward to Sunday with Jimbo. I enjoy watching you solve problems and get the most out of those little cars. Who needs an EV when you could make Kubota diesel cars that get 70 mpg. Shows what some common sense ingenuity can do. Great content, love your show.

Dude the reference to Portal was AMAZING Love the build, you have a different approach wrt install all the available high end parts on the market. Keep it up! I would also really love to see you tinkering with the electric traction part of this build.

The one thing I really look forward to on Sundays. Thanks yet again!

Oh man! I was always promised an aluminum cake after those trials. You're saying it's all a lie? No, Glados said it would be there, it'll be there. Genuinely nice lathe work btw.

I appreciate the time effort and quality of your videos!

crazy, during the accel test it sounded exactly like my neighbors civic when he leaves for work at 3 in the morning

How about a truck next? Some kind of mini Truck with a old 1,6D or 1.9TDI?

He narrates his ass off for sure this car is neat

This is easily the most interesting and fun build series I have watched!

Make a small party pulley and an idler to offset the belt from conflicting with the bracketry? I only fear the chinesium charger will make intake air temps an adventure in diminishing returns. Love the vids, thanks for making them!

Very cool. Thanks for that extra little bit. 😊

Best way to start a Sunday, week after week. Thanks Jimbo!

The Portal video game reference was excellent. The Cake Is A Lie!

Really appreciate the videos and your work on the Honda. Looking forward to the next Videos. Thanks.

The best 15 minutes of the week Awesome a portal fan The driving shots a great

Love that yall are keeping this project going and progressing. It ls one if my favorite builds to watch right now.

Well Jimbo at least if you do need the intercooler in the future it would be super easy to mount that puppy directly to the supercharger and run inline, that would shorten the charge tube and maintain direct airflow. You did great in positioning that supercharger for maximum airflow 🤙🏼

Love this series. I always look forward to the next upload. I had a funny thought though. If you built a strong enough starter ring gear, could you hook up a motor to it and have a "boost" button that activates the motor and push the car up to speed from a dig and then disable it and let the diesel take over?

Excited to see more boost! Your projects are all so fascinating and unique I love them

This channel kicks all the ass. 10 outta 10 Jimbo

Really enjoying this saga of making high efficiency motors. It makes me want to try and build my own too.

Keep up the good work! I love the narration and the theme of the projects, the diesel insight is definitely my favorite project so far.

Drinking a peach flavored monster zero while driving my daughter to gymnastics as I play this video. Your videos are always the best part of my Sunday. I really need to get the upper control arm bushings replaced on my trooper. I'm really starting to feel the slop lol.

That Portal reference was unexpected, I love it

Love this series! I wonder how much heat the "charge air" is pulling from the engine? It would be interesting to see if insulation wrap would make any difference. It would probably be as negligible as the difference the intercooler would make, at these boost levels. Keep up the great content! You can really tell how much work you put into it!!

Congratulations, you've made the car sound like an Aston Martin DB5. 😂😂

Great ep. Also been getting google telling me about your videos I've seen immediately in the past 18 months through a few different car websites. Can't wait for a turbo supercharged combination.

Love the videos...an easy way to lower air charge temps is the increase the diameter of your discharge tube. I went from a 3" tube to a 4 and change inch tube and my boost dropped from 13.5 lbs to 9.5 to 10 lbs and the decrease in velocity results in lower air temps. It's a cheater method that doesn't lose power as you are still moving the same volume of air. To help with things I had a wide mouth throttle body that decreases in size to gain the velocity back as it goes into the motor, but I'm sure a reducer coupler would have the same affect. Works great and have had the reliable setup for yrs.

That full throttle test was fun, that thing honestly sounds killer. Like a baby Cummins or old 2s Detroit.
