You need to remember that this car originally was powered by a highly modified Predator 212 cc motor which drove the Honda transaxle using a Comet CVT. That was a lot slower than this and possibly the Cars and Cameras' King Midget. This version of the Insight might actually be useable as a daily driver or for road tripping, as long as you don't mind doing without creature comforts.
The gnomes are missing though.... they used to run a muck in the garage when Jimbo wasn't around, stealing tools and the likes. I think they must have been left behind when Jimbo made the move to Kansas.
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 can't remember where I read it, but I remember reading that a diesel engine's performance improves with added boost right up to the point of condensing the intake air to a liquid, assuming the stresses don't blow the engine to pieces. I've never seen anyone test that however.
@@leifhietala8074I could be wrong but what would make sense to me would be to design an overly strengthened block, crank, rods, pistons and heads for that to be tested. I think those kinds of pressures would be far too much for a normal application.
Its closer to 1/20th of what the engine is seeing consindering ambient pressure. I have no idea what elevation Kansas is at but at sea level its 1 bar or 14.7 psi so take out the elevation difference and you have the number.
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."
Miles can be a colloquial term, doesn’t necessarily mean ‘Miles’ or KM it’s generally just a fair or great distance or amount. At any rate, enjoy being entertained my the inclusion of metric measures…
I grew up driving in NoVA and the idea of having miles and miles of straight road with nothing in front of me nor anything climbing up my tailpipe is just strange.
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 TH-cam ❤
I just went to look because I didn't see it in my feed and I was very sad. That was about 20 minutes ago. And now I look and BOOM! I can have my moment of Zen. Because Sunday mornings are now Coffee and Cantina for me. :)
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 😊😊
At 6PSI it’s negligible,flexible charge pipes vs solid isn’t gonna make an appreciable difference in performance. Ideal material is solid aluminum charge pipes, but that’s a durability modification as opposed to performance. Those reinforced silicone flex tubes can handle 20-200psi…
If the pipe doesn't burst or leak, it's not really inefficient, any dimensional change is just storing boost to use later, which is an idea that was used on some pretty cool experimental rally cars back in the day before the safety karens ruined racing.
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...
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.
making a pulley on camera for the first time: I follow a TH-camr 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." 😊
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!!
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.
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.
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
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.
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 like how he's basically building a vehicle where he can pretty much say F-you to the automotive industry & their purposely overly complex expensive repair & maintenance costs & poor fuel economy. I'd like to build an aerodynamic velomobile type fully enclosed scooter vehicle using a 150-200cc scooter 🛵 engine & drivetrain. That has plenty of room for groceries, can cruise at 65-75mph on the hyw, with decent acceleration to keep up with traffic, gets 70+ mpgs. Make the seat so it can lay flat & convert into a climate controlled sleeping pod. Priced the same as a cheap motorcycle about $3,500 that could be drove year round like a car. That's also fun to drive, for extra storage, 3 removable aerodynamic locking storage cases could be attached to the sides & rear.
@@michaelbrinks8089you should check out the Lochead Quasar or the BMW C1. Sadly, they’re both out of production but I’ve been wanting to make something like those for myself
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.
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.
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
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.
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.
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
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.
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.
Excellent results. I bet you picked up another 1-2 psi on the acceleration test over last time. My guess is this pulley ratio is going to be the sweet spot, but a larger crank pulley is still worth the test to see which provides the best performance, mpg, and temp profile.
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.
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?
I'm always surprised to see how warm it is outside of here. We barely hit 61-62 this last weekend before it started raining then snowing again. I'm in Northern Utah.
Awesome as always! But without a hub, the pulley will be putting a side lad on those bolts. That will cause them to loosen and possibly break, possibly much quicker than you would want. Could you machine a recess in both the pulley and the mount for a 3rd part, such as a piece of steel tube or a piece of that go-cart axle that would act as a hub?
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!
Another entertaining video demonstrating fabrication skills way beyond my own. That lathe is one handy machine. My grand father had one that made its way to my dads basement, which I spent hours marveling at Asa kid. Anyway, having the gas hybrid vehicle on hand for comparison purposes is pretty cool. Finding 4mpg out of the diesel will be a reach.
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.
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.
WOW you may end up with some thing awesome!!! WOW very close already!!! WOW 70 mpg everyday driver is amazing !!! WOW I bet low maint cost and maybe a million mile motor??? I am impressed with what you are doing!
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!
Always enjoy these videos! You need to know that you are going to get me in trouble with my wife because your projects make me want to not finish my already overwhelmingly long list of open projects and start new ones.
You know, you could have Alexa open a portal your finished car...but I suppose you're a purist 🤣. Thanks for taking us along for the ride - your channel is my Sunday morning treat.
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.
Probably the best modified car content on TH-cam ❤❤ In my experience, alloy v belt pulleys wear pretty quickly, and deposit material on the belt, which can lead to odd noise and or slip issues. Altough given the usage, it will likely be fine in this instance. steel or even cast iron ( carefull with the diameter / speed ! ) might be a better option for future pulleys? 4.5 seconds is way, way closer than i thought it would be. Great work! 👍 Cant wait for the next one 😊
This is the slowest highly modified car on TH-cam and I love it!
Cars and Cameras' King Midget might argue that.
Yeah, but this clatter box will run longer than all the super duper turbo super charged clatter boxes...

My grand father had one that made its way to my dads basement, which I spent hours marveling at Asa kid. Anyway, having the gas hybrid vehicle on hand for comparison purposes is pretty cool. Finding 4mpg out of the diesel will be a reach.
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.
"the cake is a lie" HA! love it!
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.
WOW you may end up with some thing awesome!!! WOW very close already!!! WOW 70 mpg everyday driver is amazing !!! WOW I bet low maint cost and maybe a million mile motor??? I am impressed with what you are doing!
At 9:06 did you do a conversion factor for no miles to no kilometers 😂
"...the good news is 5:28 I don't care...", Brilliant!
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!
Always enjoy these videos! You need to know that you are going to get me in trouble with my wife because your projects make me want to not finish my already overwhelmingly long list of open projects and start new ones.
9:04 'Preciate the unit translation, there. We'd have had no idea you were going some distance otherwise! :D
You know, you could have Alexa open a portal your finished car...but I suppose you're a purist 🤣.
Thanks for taking us along for the ride - your channel is my Sunday morning treat.
That would be cheating....... Hmmmmm
Such a small difference on the pulley dropped 2.2 seconds I would have never thought that. Very interesting.
whoops. answered the wrong question. Yes, indeed the 2.2 second drop was way more than I expected as well.
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.
Best way to start a Sunday, week after week.
Thanks Jimbo!
Probably the best modified car content on TH-cam ❤❤
In my experience, alloy v belt pulleys wear pretty quickly, and deposit material on the belt, which can lead to odd noise and or slip issues. Altough given the usage, it will likely be fine in this instance.
steel or even cast iron ( carefull with the diameter / speed ! ) might be a better option for future pulleys?
4.5 seconds is way, way closer than i thought it would be. Great work! 👍
Cant wait for the next one 😊
crazy, during the accel test it sounded exactly like my neighbors civic when he leaves for work at 3 in the morning
The portal reference caught me really off guard
How could a perfect morning be anymore perfect, with an AMR500 video of course.
Looks like you are getting close to the sweet spot. I am guessing a few more PSI not a lot will will make that engine even happier.
