Something's Wrong Here - Off Road Wrecker Problems! 

Of course bleepin jeep would be in the comments with this kind of joke 🤣

That joke is deadly funny.

Badum tish!

That’s silent butt deadly! Lol

You stole my joke lol my grandfather said that to me growing up it was funny as I did live but that gas had my confused at the time till that rat I thought was my grandfather stopped talking to me. Man what a day that was

Truth

It's on my to do list for tomorrow matter of fact 👌

I spend a lot of time tryin to save a little time

@@brapbrapmafucka all the time

OR you just finished a 3 hr job. then saw the way where it would have only been 1 hr.

Or turn the beast around so the exhaust is facing out the roller door.

@@johnt.848 lol, it seemed an obvious solution ...!

Little creepy doll head on his hat....

I once saw a rolling truck chassis being delivered to coach builders, which was being driven with no body parts. The driver was out in the open, wearing a motorcycle helmet. Thinking about the Heavy Wrecker, it can surely have room for no more than two, or three at a stretch, people, so they'll still have to take the Morvair or Jeep for the crew.

@Stu Nick I was thinking about the Snow Cat the other day as well. News last night was showing snow in Co. already. Sooo much to do, So little time. The Frankenana is Job One for now though.

It is all about "emissivity" which varies with the material and the surface. In the mid 80's I worked for RayTek building and calibrating IR temperature measuring systems.

Its a waste really when a laser point heat gun will tell you all you need to know. Though i do love FLIR cameras for finding shorted electrical issues

@Grant Davis I came here to mention emissivity but you beat me to it

@@rickstorm4198 Laser points also have limitations with reflective surfaces. My laser point came with a reflective surface chart based on material if I recall correctly.

@@rickstorm4198true, but if you had a FLiR camera laying around you're NOT gonna use it??

Is that those things that just poke up out of the ground? 😆

@@Bryanja81 no it’s the things that hang from the heaven

I appreciate that they’re using for all intents and purposes a junkyard engine. I can’t stand the shows that have $1 million budget ordering crate motors and thousands of dollars of merchandise from specific online retailers which turns the entire build into a commercial. I love the way Matt and the crew just make a deal. And transform regular cars and trucks with just stuff anybody could get.

@@hidel308 That's why I stopped watching one of the channels that does it. I couldn't take any more of the commercials.

​@@Bryanja81😢🎉😢

I was like this with the Morrvair and now even more so with the wrecker, can’t wait to see it on the trails

Who

Even in this century, many times you still have to adjust your crank/cam sensors to give signal when you are actually at position. So you are not tuning the system with it, just calibrating the sensor to give TDC reading when you are actually at TDC and you are done with it on the mechanics side.

Hahaha! Love it!

You could go into the fuel table add or take away then add or regard timing kinda same as what you said but newer engine it seems like Matt always has to go through the hard way

Lol I wish that was still the way. I think you mean 14mm by the way

Gap the points with a dime, advance timing until it just starts to 'ping' under load, back-off timing just enough to eliminate ping under load & your done ! ! !

There's a huge difference between welder and fabricator. She is becoming a very good welder. No doubt about that. Every time you weld it's practice.

Okay, but wouldn’t the highest temperature differential exist between the hottest coolant and coldest air??

@@buellb0y ​ Sure, that's how a single radiator works too, and that's basically what you'd have in this configuration because the rear radiator won't have enough of a delta (temperature difference, or thermal gradient) to dissipate much heat. If you're feeding 170F air into the rear radiator from the front one, and then you pump 170F coolant through the rear one, you're going to end up with 170F coolant coming out, meaning your rear radiator did absolutely nothing for you. It's not quite that drastic, but when your cooling air and coolant are close together, dissipating heat requires an exponential increase in surface area dependent on the thermal gradient. In layman's terms, that means if your coolant and cooling air are nearly the same for the rear radiator, dissipating the same heat as that front radiator with an ideal delta would require 4x the surface area for the rear radiator. So why bother with two if you're getting virtually all of your cooling from one? Ideally, a simple baffle separating the two radiators would give even better cooling than having the coolant lines properly routed, since you could give the front radiator ambient air directly from the grill and pass it up and over the rear radiator to the engine bay, while the rear radiator is pulling ambient air from underneath the chassis and pushing it directly into the engine bay. Then it wouldn't matter which radiator gets the coolant first because they're both getting the best delta possible from air at ambient temps. There's enough room between them that it won't affect the volume of airflow going into either. It would be a simple matter of dropping in a flat sheet of aluminum diagonally between the bottom of the front radiator and top of the rear radiator, boxing in the sides between the rear radiator and baffle with two triangular sheets, then securing them all in place. Air leaving the front radiator will be able to go over the baffle and around the sides, while the air going into the rear radiator is coming entirely from the bottom. It doesn't need to seal perfectly, but it wouldn't hurt to minimize gaps either. It would also have the additional benefit of having some airflow in the vicinity of the other coolers located in that area, since it'll be moving air in that vicinity any time the engine is idling, rather than letting it sit and hope the wind is blowing over them. Make everything work to your advantage by having everything work together.

I was just taking to my son about this engine! It seems like a forgotten gem…

@@roninkraut6873 definitely! Cheers!

Two bucket list goals achieved in one vacation. Not bad

A Custom Built Fury Road BEAST by Matt's Off-Road Recovery! Basically, it's a Rock Crawling Tow Rescue Vehicle like no other. Remember - this thing is going to have 54" tires on it - six inches shy of FIVE FEET!

Where are you on your bucket list vacation The Dave?

@@MrEvanNoyes Better tell NASA !!

@@derekisthematrix New Orleans.

I didn't see Lizzy doing anything... what's up with dat?

@@edbenson98 then who was the blonde welding the exhaust?

@@edbenson98 It appears you weren't paying very close attention to the video.

Pulling a tour bus out of the sand...

It's going to overheat under load. Electric fans are for Camry's. NOTE: This engine does not come with electric fans... for a reason. Mechanical fans use 4 hp for a reason. They move more air.

@@TheBandit7613 racing teams use electric fans all the time. Why wouldn't it work in this situation?

@@mrpasciak92 probaly because when race cars are under heavy load it's not that long. Also they have methanol etc to help cool aswell. But I'm not saying you're wrong. Watching race week might makes sense.

@@mrpasciak92 Not enough CFM. Don't see them on any trucks do ya? Nope. There's no magic to moving air. All it takes is energy. The stock belt driven fan can be what, 3 to 5 horsepower? There's a reason. Imagine the electrical system it would take to turn two, 2 hp fans. That's a LOT of juice. Fans are a frequent discussion on our Jeep forums. Matt's Jeeps (and Rory's) are usually running hot all summer. XJ's are at a disadvantage. Stock, they came with a smallish belt driven fan and a med size electric fan. They automatically run hot here. (I live 30 min from Death Valley) My Jeep can handle any heat on Earth because I had a radiator custom made by a shop in Henderson Nevada. ($$$$) It's huge, takes up the whole front of my Jeep with a custom shroud. YES, the fan robs a lot of power when it's hot but it doesn't ever overheat. Matt will eventually get it worked out, that I'm sure of. Cooling systems are my specialty.

I think that is the power of the tech they called in for help as he knew what to do. I think I once bricked a PC a good number of years ago by trying to upgrade the BIOS and it all went sideways but at that time, I think the answer was, you were done for. Now, not certain if you can fix it or not but anyway, I do not bother with the BIOS. I have updated all the drivers however for the motherboard on several occasions successfully.

@@johnhpalmer6098 In the old days, a failed BIOS install could really only be fixed by replacing the BIOS memory (like literally removing and soldering a new one in). Nowadays, they have a redundant chip that they'll reload from, sometimes if you switch a jumper and sometimes just automatically if the BIOS fails to initialize.

@@JGuraan That's true, but most of us likely didn't know that we could just unsolder and replace the chip, let alone thought to do it, at least it never occurred to me in the past. I know more about computers now than I did back in the day.

@@johnhpalmer6098 Yeah, I don't know how easy it ever would have been to get ahold of one of those chips anyway. It'd probably be something you'd have to send the board to the manufacturer for, and who knows if they'd even be willing to do it. For all intents and purposes, prior to the redundant setup, a failed BIOS flash was a bricked mobo.

@@JGuraan That too, however, there are often markings on the top of the chip and a quick Google search these days can reveal the info on it, then you can likely find it's a common type of chip that can be had at places like Mouser and then replace, reflash with the correct BIOS info. Harder to do on older gear that's not been made in years or decades though, unless you can find an archive of older bios' from various manufacturers somewhere. Mind you it's all conjecture now since as you say, more modern computers have redundancies onboard the motherboards.

That camera looked like the one I have, you can adjust them for varying emissivity if you know roughly what it should be.

@@marvindebot3264 Sure, if you know, but even if you polish the metal some level of oxidation will form on it especially once its hot and then what does the emissivity become? A painted surface should be pretty close to 0.9 or 0.95. It's not uncommon to paint something you are going to look at with an IR camera just to make sure the emissivity is consistent. It appears they are mainly doing comparative tests, so maybe it isn't critical to make sure the reading is accurate, but I just wanted to point out the common issue when looking at metals with a thermal camera.

careful folks, the reply to my comment is a fake account using Matt's logo to scam!

👍

You as Well

Once you've had a very stressful, complex job that's always changing, and thousands of people depend on you, a job assembling something starts to sound pretty appealing. Lol

I have 3 inch on my 454 sounds so good

@Dave Hancock Excellent observation. Back pressure increases low end torque. Less restrictive 3" pipes allow more top end power at the expense of low end torque. Torque equals pulling power. RPMs equals speed.

@@tomparker9966 that is an old wives tale. the gas velocity through the collector is the only thing that matters, having too large a collector will limit the scavenging effect leading to worse VE and less peak cylinder pressure.

That's not how it works

@@austindoud273 well not on a 2 stroke with an expansion chamber, but if we are talking about a 4 stroke.... yes it bloody well is.

And Matt was almost yelling towards the end of the video with the engine off which tells you it was doing damage.

Unsafe working conditions are their shtick.

@@zekeabercrombie3583 Bloody dangerous, IMO.

She don't wear make-up like her younger twin sisters.

Plus on hearing. You don't worry about it now but later it's huh, huh, whadda ja ya say, can you repeat that. There's always hearing aids but you want to avoid that. Music never sounds the same.

@@Jeff-jg7jh Agreed. It's the same thing with their haphazard eye protection when welding. You only get one set of ears, and one set of eyes - once they're gone, they're gone.

Yeah for real. I did just buy a 6.0ltr 400hp m120 v12 for a vintage Mercedes restomod project and I can't wait to see what it sounds like with minimal muffling. It's real hard to beat the sound of a V8 at idle or 6000rpm + though. My little 200ish hp 4.5 V8 sounds so good screaming 6500rpm.

Nah, the skills ended when electronics came to play

Maybe with the fat pipes you're really needing a bit of back pressure.

Crossover exhaust for 60 on 46s,

Heat-shield and a vent would also do the job.

I would coat it and put a heat shield on personally. Something like the OE would use, the hard foil covered plate stuff.

Compressed air isn't hot. Once it is released into the tank, it rapidly cools from expansion. Only the copper tube between the compressor and the tank should be hot. Just like when an air tool gets cold in your hand and starts to sweat, same thing with the air in those tanks. That exhaust isn't going to affect the air.

@@mikeworkman3593 that copper tube do be hot tho. source: experience.

@@Raindrops4891 Oh hell yeah, it'll melt your skin off lol. But as it expands into the tank, it'll cool off until it reaches equilibrium, where as it'll stop the compressor anyways. The small tube gets hot due to the small amount of metal to disperse the thermal energy it stores. This is why many times You'll see custom jobs take a long piece of copper tubing and make a long spiral out of it before it enters the tank, by the time it gets there it'll have kept the tube cool. The compressor heads are normally made with aluminum and have heat fins, so they wont get as warm as that copper. I work for government transit, so I deal with air brakes and suspension on a daily basis(well I normally work on the more complex stuff, like electrical hybris buses and a/c, engine codes, etc. But I've been doing this since I was 16, and I'll be 47 this month) so we have to maintain the air systems. Of course they don't use copper tubing anymore(they used to though), it's all rubber with stainless steel braided coverings. I'd rather have the copper though, it doesn't look at fancy but it lasts forever.

"Early days of PC building" with "USB port".... In the early days we used jumpers for the motherboard configuration AND cards configuration. Firmware updates were rare and you had to use floppy discs. USB is pretty modern.

Ya, sorry about that. Some of the bios/firmware code was to fix hardware issues that would be to costly to repair with new runs.
