Gas popping the fan blade might be from some kind of thermal contraction/expansion. If the blades were warm and the gas was spilled on them, the evaporating gasoline would have caused those blades to cool down rapidly. This may have caused enough stress internally to the plastic fan blades to cause them to break/pop off.
Yup was going to tell the same, looks like temperature shock.
My guess as well.
Considering they're most likely nylon, I doubt the gas itself has anything to do with it, rather just like you said thermal shock.
Computer fan blades have rather strict tolerances for expansion, considering the cost, since it affects performance. That means a stiff material used
it's probably bc the gasoline dry rotted them/ corroded them
Not only that, but I also bet the fan blades were already quite fatigued from the high temperatures in the engine bay, these fans are only meant for computers after all.
The fan blades might have been thermal shock or just crappy injection molding with a lot of internal stress. That's an interesting issue however.
I had oatmeal for breakfast, but I am a mechanical engineer, and agree with this hypothesis.
theres also the fact the stream of gas would of slammed the blade into in the rad, compounding any defects wether they be a moulding issue, installed wrong and rubbing, or ate some gravel whilst driving
The top of the fan blades are also matte which gives more surface area for the fuel to evaporate off, and gasoline has very high calorific values Btu/gal (when it evaporates like butane it gets much colder) which made it act like a freezer. plastics do not like rapid thermal expansion/contraction and POP!
I had lucky charms, and I'd concur. Between the molding, the possibility of a prior internal fracture, and pouring the fuel onto a warm blade (assuming they were sitting in the sun).
I ate breakfast at mcds and U guys are all wrong it was those damn Gnomes they broke the fan blade to sabotage this guy's experiment!
'We replaced the crappy gasket with an identical crappy gasket......." 🤣🤣

SO, there is a really interesting thing that happens when you get ethanol on acrylic. It hydro cracks. If you have seen all of the spit barriers in the stores cracked its because someone cleaned them with the ethanol containing sanitizer. I don't know if this is what happened with the fan blades, but it a possibility. As for the test, ethanol evaporates pretty quickly so if the test sample had been out of the canister for a while maybe the ethanol was evaporated off enough.
Captain Crunch for breakfast, I can tell!
It’s called crazing and Ethanols and alcohols will do that to Acrylic. The material used for the fan blades is typically a nylon either 6 or 66 depending on the temperature exposure. My guess is there was some molded in stress and the stress was relieved from the thermal shock of the gasoline hitting it.
@@TheOriginalLugnuts that would also make sense. I am not sure what the mold for the fans looks like but there might be a "weld line" where the blades meet the hub.
@@mitchfillbach1115 A light bulb just went off in my head. 📡
@@kansasrose2909 Is it because JImbo is a genius????
the plastic blades, when they moulded them at the factory have a high stress area in the corner. this is caused by the plastic cooling fast on the outside and slow in the middle. the middle shrinks causing the high stress area.
if you get some clear plastic cutlery or look at a set of plastic headlights with a pair of polarized lenses sunglasses, you can see the stress areas in the plastic.
acrylic plastics are very susceptible to solvents, where if there is a high enough stress moulded into the plastic the plastic will break down a little from the solvent and the internal stress causes the plastic to crack and split.
very similar to safety glass or "tempered" glass
Sounds about right. I've had the same happen to the cheap plastic buckle on a shoe when it got a little splash of gasoline. Instant disintegration!
Same principle is what creates the Prince Rupert's Drops.

The car performing better in the heat probably comes down to drivetrain losses;
Grease in CVs and wheelbearings is thick, gear lube in the manual trans ( diff) is thin, but thinner when warm all reducing parasitic losses.
Warmer temps also generally means suspension components settle better because all of the bushing, rod ends etc move more freely, having everything settled and neutral is very important for low rolling resistance.
Speaking of low rolling resistance, heat will increase tyre pressure reducing rolling resistance, so thats a plus.
Can also try ATF in manual transmission to lower drive train losses. Some 4x4s here in Australia use atf in manuals so mustn't hurt anything
hey jimbo, speaking of fan blades, remove the fan from the flywheel and put an electric fan on the he head, something like a delta tfc1212de. pretty much all of those fixed mounted mechanical fans are super inefficient compared to modern fans, i wouldn't be surprised if it was using up a whole(!) horsepower.
I cant explain the fan blades cracking, but I can recommend getting some industrial fans to replaces them. Noctua makes some very robust fans, fiber reinforced blades, water/oil/dust resistant, etc. Not cheap, but maybe worth considering if you are still going to use that little pc cooling radiator.
Unfortunately the way that cooler is designed combines the motor for pumping and fan in one unit. As-is the whole unit is compromised, but should™ last the life of this experiment
@@gutserker A lot of this is completely unexpected.
@@kansasrose2909 We have come to expect genius from JIMBO.
I'd like to see this with classical clutch and just the 5 speed, might be faster due to higher efficiency.
Hes gone over this in previous episodes, these engines dont have a thrust bearing like a car so the tension from a clutch would destroy the engine rather quickly, these engines bearings are made for side loads instead, so to run a clutch would require him to either use his engine to run a secondary flywheel that is just powered by the engine via belt or chain or he needs a whole different type of engine
After fully sheet metaling the bottom of my old race car I noticed better gas mileage, smoother at high speeds and less wind noise.
i’m upset i found this series last episode, but so damn happy i found it in general
A lot of this is completely unexpected.

@@mommapanda5736 Is it honey bunches of oats??
Take the gearbox out of the occasion; a fixed custom made single gearset replicating your current 4th gear ratio will reduce driveline losses and most likely improve 1 to 2 seconds on your 0-60 (my 2 cents).
Keep us posted on your ventures; loving the series!
4th in a 5 speed is often 1:1 but can vary a little, either slightly over driven or slightly under driven. A fixed ratio between 3rd and 4th, but closer to 4th may prove better. Dual cvt setup could be an exercise in crazy futility, or something amazing!
You can add washer to stiffen spring witch will raise engagement rpm
Plus if he'd get a damn shorter belt.
@@midixiewrecked7011 Damn right!!
@@mommapanda5736 💖💖💖
We use to drill out the steel weights inside the sliders to get the desired weight reduction. I would recommend you do the same. For as far as the fan blades, some injection molded parts, especially thin and long parts like fan blades, can have high internal stresses due to cooling too quickly and shrinkage. If it's a stiff polymer and it's hot (probably was) then dumping gas on it which extracts heat very quickly to evaporate, you could cause the part to fail. It's just my best guess.
👍👍👍👍
1:44 - slipping due to light pucks is not the root cause, but an effect of increasing horse power at given rpm. The spring is the one that drives the tension, the pucks adjust the rpm the CVT shifts at in combination with the spring. But for tuning, you normally increase the spring first to get higher torque transfer without slipping (which also increase the rpm), then adjust the pucks to make it shift at the optimal rpm (peak hp) 🤓

@@kansasrose2909 Is that because Jimbo is a genius??
Yea, get rid of the plastic as much as possible
I remember a long time ago we talked about the injector :) I was packing some garage stuff to move recently and found perfect injectors for this, thought about your car immediately when I saw them! Problem is that I live in Sweden and you probably got injetors by now :)
New project car is a Fiero 🤣
Thanks for adding some SI Units for us non-Americans
could be the fact that it did react a little with the plastic and where the blade meets the hub is just a high stress point
If the HG pops again, try to find a multi layer steel gasket. Those can hold up to some serious boost.
Or just make your own HG out of annealed copper sheet.
Good call on that exhaust leak. Every time an exhaust pulse passes the leak it creates a low pressure gaspocket behind it which in turn allowes ambient air to be drawn through the leak into the exhaust which in turn will be pushed past the O2 sensor scewing the reading. The sensor will detect more O2 and the ECU will start dumping more fuel in, more then is really needed.
These are both great ideas

No Capt crunch, I had some "Love Crunch" this morning, which is kinda the sidekick of Capt'n Crunch, and she's telling me, that most likely the blades have been hit by a small pebble, or a bug during operation.

The Suzuki Maruti 800 had a 3 cylinder, 800cc engine making ~35hp, and it could hit ~140km/h with 0-100 in just under 21 seconds. Now, the car only weighted like 680kg, but I feel like little cement mixer engine has to be churning out at least 25-30 horsepower with the performance you're getting from the ~870kg Honda Insight.

You can get old fashioned gas can spouts online, if you're tired of the California approved one that seems determined to spill gas every time you use it and leave its o-ring in your gas tank.
Or get a No Spill gas can. They are a bit pricey, but also the only decent one I have seen for sale these days and it's very easy to use since it's operated by a button instead of some stupid sliding spout mechanism. I'd suggest trying one if you use gas cans with any regularity, it makes life so much easier and is worth every penny.

Hey man, huge fan here: Was just thinking and I'm sure it's been mentioned but in future videos if you upgrade to the 670cc 22hp HF engine it might be more interesting as well as useful to some people as that might be a legitimate engine swap for certain vehicles, albeit quite underpowered but definitely an option with new engines costing a literal fortune, mechanics shops booked for months ahead of time, and gas being over $5 a gallon-I could see some enterprising poorer folks dropping in a 670cc and just rocking it. Anyway, it just popped into my mind, have a great day and I appreciate all your videos.
It would probably work fine in a subcompact like a Ford Aspire. It only had a 1.3 to start
The 670 is in the works!
As a non united states habitant, and may i speak for the rest of the world, THANKS for the metric conversions on the edit, yall northamericans have me converting everything in another tab or on the phone to make some sense to view!
Regarding cvt slipping and temperatures: i have seen paints at racetracks in pits that dissapear or change color within X temperature is reached, this is applied to disc brakes to monitor cooling, top temp, and whatnot. Im not sure how this paint is called but you paint stripes direct in the edge of the disk or in this case clutch!
Also you mentioning removing the gearbox, what about a direct coupling to the honda gearbox, but with a centrifugal clutch, and a one way bearing or sprocket like the ones on the rear of bycicles. The combination of these two may make the gearbox more usable without the need of an axial clutch, just let go the gas, wait for rpm to drop a bit and next gear shoud enter..¿easier? and not waste any precious kg/m on slipping and heating a belt!

The fan blade may have already been stressed in some way or maybe even partially fractured and the corrosive addition of the gasoline may have been enough to finish it off. Also I'm a 19 year old from Michigan and am modifying a chevy trailblazer with a stock 4200 vortec with parts from a gmc envoy. My plan is to find out just how much power you can safely get out of an inline 6 with a stock transmission. Also the gmc will likely be used in a demolition derby in the near future. Let me know if you want to meet up and work on a project.
The flex joint spurting exhaust out probably means its unwound on the inside and creating a serious amount of backpressure. Just something iv seen time and time again.

Wheel bearings and drivetrain while cold are much harder to turn, warmer weather like 90°F+ you'll find MUCH lower rolling resistance. As we know the less resistance in the powertrain equals more power transferred to the wheels. This may sound counter intuitive however if you do a top speed run 1st, then the 0-60 you might shave a second off due to less drivetrain resistance when at operating temp. The transmission oil weight might also be something to look into as well as open bearings in the wheel hubs instead of sealed (much better rotation at the massive cost of longevity).
Great video series!! Thank you :)
Yep, this is a theory of mine as well.
The tranny oil to intake trick was a fun thing I did in the 70's to back off tailgaters on the highway. I used an ANCO wiper fluid motor drawing the tranny oil from container, using a push button placed inside of my '77 Dodge 360ci truck at the time, I could smoke out a dangerous tailgater when traveling on interstate, and they always fell back, or quickly passed me at first chance. Since the truck came without catalytic convertor in those years, damage to such wasn't a problem.
I'm the guy who recommended the PC water cooler, snap 1 fin on the opposite corner so it's (mostly) balanced with 4 top and 4 bottom fins, I've serviced quite a few computers where that was done "temporarily" to stop vibration
Thanks! A few more blades have fallen off since we shot that segment of video. We ended up snapping off all the blades so the water pump would still work.

Not surprised to see the headbolts lost their spec after a run.. We build several engines with ARP 625s that require a hot torque for this reason. My suggestion would be to source a MLS gasket (I found a few online) as well as studs if possible. Unfortunately, clamping force and gasket material are gonna be the life and death of that engine under boost. Luckily, looks like IATs are under control, so as long as you can figure out a way to keep the top-end and clutch happy, its time to add boost and fuel.
Also, really good call on the noise interference seen in the datalog- you're a lucky dog it actually showed up there though lol! With a lot of the in-depth electrical diag I've done on vehicles for noise interference, it will set DTCs but the scanner data stream won't show anything out of place due to the refresh rate of the scanner data vs what the PCM is actually able to see. Normally have to use a scope to find those failures..
As for the fan- nothing surprises me anymore when it comes to plastic.. Obviously certain plastics are very strong, and very reliable.. however I see failures almost daily with cheap CAIs, E-fans, etc that just aren't designed to handle the heat in a closed engine bay.
My father was a old school engine builder. We was very particular about head bolt torqueing. His method was 5 stages walking up to final torque. He would also ALWAYS hot toque and engine at the end of the cam break in, and then check it again hot after a week of operation.

I have a fiat 500L, 18hp, and it goes happily over 60mph :D but not by much. Maybe I should ask Jimbo for a supercharger advice🤣
Fan blade snapping is from solvent absorption. The test you did to check for susceptibility wasn't actually telling you much, because plastic+solvent behavior can be really confusing and weird.
Even if it doesn't melt entirely, it can easily soak up the gasoline and change the material properties of the plastic.

Cheerio eater here.
I have a couple of ideas for why the supercharger isn't giving the response that you expected.
1, It could be parasitic loss from driving the supercharger.
Try driving the supercharger slower, or alternately, try to improve the airflow through the head.
2, It could be drive losses through the variable speed clutch.
Try replacing the variable speed belt with a fixed speed chain, and use the 5 speed to change ratios.
You won't be able to keep the engine rpm steady, but it will help isolate the problem.

Have you considered ditching the TAV and just using the 5 speed? Perhaps a centrifugal clutch with about a 2:1 jackshaft from the clutch to the transmission? You'd have to hit every gear but I feel like you're losing alot of power through that cvt
It aint a cvt
But yeah torque converters probably lose a bit of power
Using both a torque converter and a 5 speed is a little redundant
Just use one of them to reduce parasitic losses
Idk tho
Dude has been working on this forever and probably knows what's good for this car

Replace fan and move on with life. I loved the gnomes are sabotaging the car haha and any restriction that can be removed in the exhaust can affect the blower. I’d expect improvements even if small with the 02’s reading properly
I dont know why it popped off, but ive had this happen to a computer fan in my computer because of wire obstruction and the missing blade cause excessive vibration. I had to snap off a blade from the other end to balance it out. You may not have to do this but you should run the vehicle with your cooler fans on to check if its vibrating too hard. If it does it could cause premature failure on the fan if left unchecked for idk how long. You should replace or snap off the opposite side blades.

See if the manufacturer of that gas can makes water cans of the same mold, then if they do, ask them about buying a replacement spout and vent cap for a _water_ can. DO NOT mention gasoline at all! I've heard you can do this with Blitz.
From working with fans in a professional environment one of the primary failure mechanisms of fans is the molding process leaving the plastic highly locally stressed. The glass fill may also be poorly controlled or too much regrind included for cost saving purposes. Nearly all cheap fans have blades that are poorly molded and can snap off at the most inopportune times, kind of like how an old rotten tree might fall down on a windless day when a storm passed through only a week before. I wouldn't think too much into this as it's a common failure in inexpensive or poorly sourced fans. You probably just thermally shocked it or something of that nature. There's a reason high quality fans cost so much more than the low cost ones. Any quality manufacturer tests the crap out of any fan they source and finds those flaws before it ever makes it to the customer. You don't have that luxury!
Thanks!

It's residual stress from the injection molding. There are microcracks at the surface that have high surface energy at the tip, when the solvent gets to them the cracks accelerate and release the stress. You can get the same effect if you have those old injection molded clothespins, clamp it on your finger and spray it with acetone. It'll immediately break apart.
👍👍👍
I've had many vehicles which were "gutless wonders", but this takes the cake. Not a bad car for a flatlander.
Makes sense that the inner part of the blade would have been the hottest and most susceptible to rapid temperature change. Gasoline boils/evaporates/etc at a lower temperature than water does too, which means something that wouldn't 'instantly' boil water might still do it to gas which would subject it to the greater heat loss of its 'latent heat of vaporization' vs if you dropped water on it. Just a thought. Continuing video now...
That sounds interesting..

Does Jimbo have ties to NASA??
@@mommapanda5736 I bet Elon is trying to recruit Jimbo. Will need some heavy duty talent for that little mars project.
re: fan blades breaking on exposure to gasoline, my guess is either (1) the blades were glued together w/ gas soluble glue for w/ever reason, or (2) a tiny crack had developed in the plastic & filled itself in w/ brake dust/pollen/oil/grime/etc., & that material absorbs gas & swells, breaking the plastic on contact
love the scatches at the end of the videos ^^
Love those scratches🗯️🗯️🗯️🗯️🗯️🗯️
For your clutch issues if you would use roller weights instead of your pokes Rolla weights will sling in and out a lot faster and more reliable
I had a sausage roll for breakfast so im going to say the gnomes snapped the blades off.
This answer makes the most sense. ... especially the delicious breakfast.
@@robotcantina8957 Looking forward to the next build, Robot.
sausage roll, yummy
pro tip with the fan, just snap off the opposite blades .. good to go.
Those super Seal head gaskets are amesome
Gasoline has a deleterious (crazing) on some plastics and I suspect that is the issue, but it usually takes longer than 'instantly' to affect common thermoplastics. The Ethanol in the fuel may also exacerbate this. I did not have Captain Crunch this morning so I'm not fully up to steam as of yet.
I think you're right. I've seen alcohol crack some acrylics pretty much instantly. I wonder if some of the alcohol could have floated up to the top making for a higher concentration on that first bit that poured out and just happened to hit the fan, hence not being able to repeat the results by soaking it in more gasoline.

I knew it, the gnomes are loosening bolts on purpose. Since the next episode is #13 perhaps it's time to wage war on the Gnomes

The fan blades popping off might be due to being damaged before you bought it and the gas dissolving the glue they used to stick them back on. I've fixed many a pc fan with stuperglue. Once a blade has been broken, it's not hard for it to come off again at the most random disturbance.
@@JackHudler Yeah, I'm aware. But he got that radiator/pump/fan combo from the jungle site. There's no way to be sure that it wasn't damaged before HE bought it.
Make sure the engine's crankcase is properly vented or the crankcase could be under pressure while making boost and for the fan blade it may have been super glued back on from the maker so when the gas hit it it broke the bond
@@JackHudler correct I shouldn't have said maker but instead reseller I have a RTX 3090 graphics card and one of its cooling fans was glued back on seems to be fine but that was my experience with Ali express 😂
@@JackHudler I'm pretty sure my graphics card was used but when I got it it did look brand new besides the obvious blade being glued back on .... I'm thinking somewhere out there someone is able to get product that did not pass quality control fixed and then resell
@@JackHudler Robot, we love this channel.

I see the cereal crowd agree about thermal shock is likely. What I don't understand now is the gnomes seem to have their own film crew and they attach their content to the end of yours somehow. 🤔
Are you ready for the thermal heat dome this weekend? 😜😜😜😜😜 Those gnomes show some spunk!!🧙♂️🧙♂️🧙♂️🧙♂️😜
I'm guessing with the very low horsepower and torque numbers you're dealing with, you're probably dealing with drag induced by oil and grease temps in your transmission, wheel bearings and CV joints. I know from doing a bit of hypermiling with my old Saturn that it would get measurably better mileage on warm days for this reason, especially on short trips. Once you've driven enough miles to warm all of those oils up the difference probably becomes negligible, but you're not doing that with this car before your test runs, so that's probably what's going on.
Great comment here.
I'm really taking interest in what you're doing to this little Honda because I am in the process of buying a 1991 Honda Accord and the motor and everything is set up just like yours and gas is it's getting expensive
Your videos are awesome. Always have me cracking up over here. I love the bit about the cereal. Perfect amount of comedy injection for your unique style of video. It's been a blast to watch this channel mature into one of my favorites. We love you guys! Y'all do amazing work!
