Matt's Off Road Recovery.

So this thing is snapping outputs just dinking around testing and the intent is to able to drag a dead rig out of a trail? :laughing:

Possibly the intent is to get people to watch YouTube videos. I’m not sure, all I know is from this thread because I don’t have the patience for the videos.
 
So they snapping output shafts on a transfer case that they had to use because their beefy one wasn't finished in time?

I think it was installed and briefly tested but both front and rear popped out of gear badly so it was swapped for a 205 with stock outputs (possibly).
 
Some of the irate commentary on this is pretty obnoxious. You guys are acting like this should be as engineered as an Ultra4 rig. This is the towing world’s equivalent of a farmer making his own grain truck because he can’t find one that fits his needs. Trial and error is how the world progresses. Except for on here, where we’re all geniuses at everything EXCEPT surrounding ourselves with loved ones and making an independent income with them as a part of it.

I would’ve built this thing differently, too. I would’ve analyzed 8000 things until I hated the idea of it, and never started. Matt’s way is infinitely more effective than my way.
 
Agreed, web wheelers love to show how they would NEVER be able to do it.:stirthepot:


Heres my math, this seems like something I might have fucked up too.
This is mostly guessing, anyone know of the loaded radius of those tires? I just used 54" diameter, thats probably not right.

The questionable part, 203/205 doubler ? stock ratios? 54" tires?

Road speeds, I'm not sure but 226 mph is maybe too fast for hydraulic steering. :homer:

The problem with a lot of these you tube guys is that they're stumbling over issues that have been figureed out a long time ago, but don't want to put in the research to figure it out.

OR;
Like a newspaper/magazine columnist; rewriting a story/article of a topic, that was written many times before, for the nOOBS.
Having a Fourwheeler mag subscription for 15 years; I've seen the same articles circulate time and time again.

Oooor....they already know the fix and are waiting for parts, but they can drag the trial and error out over a half dozen new videos. That last "testing" video made him about $15k in ad revenue.

Matt's way is public and for-profit; "comment, like, & subscribe" - it's an entertainment project more than a fab project.

Like any other type of whore, discreet ones get less heckling than street corner cocksuckers :laughing:

Even so it doesn't look like fun changing those broken parts and he's definitely gonna have a hard time being competitive against the others in the tow truck Olympics with plastic transfer case shafts.

I'm not arguing that the dude isn't an idiot mechanically; rather, I'm arguing that some of the dude's mechanical idiocy could be intentional to generate more content for his entertainment venture. Dunno :confused:
 
Anyone ever hear what ended up happening with Matt’s court case AAA had against him?

He has an ORD Magnum-- 2.72. Only the NP205 got swapped in when the other case wasn't working.

Updated with magnum 2.72
Still no where enough reduction in the axle to get the shaft speeds high enough to keep from boom.
3000 engine RPM = 263 drive shaft RPM.

More dumb ass math says 250 hp into a 63 rpm shaft = 20841 lb ft of torque...
Every doubling of shaft speed reduces the torque output by half.

Am I way off base? This is the first time I have gone this far into drive shaft speeds, gear ratios etc.

What are you using to generate that?

I did the shaft rpm on my own so they are possibly no good, any of it might be no good actually.

Like was said here or in the MMW thread their final drive ratio is the same as 31.5"s and 5.14 axle gears but they have all that rotational mass and back-drive through the planetaries.

The concrete truck drop boxes are massive. I’m sure he would not be able to wreck one. The front discharge mixers go through some real shit :lmao:. You can run these thing on the street np. The guy we crush for drive 3 front discharge trucks from sc to wi none stop going 60-65 mph.

1:1 ratio though

Honestly, a SCS box is what they need.

I guess he'd lose front digs and all that fancy shit.
That seems like converting to that would be major surgery.
I wonder what ratios Midnight PAnic is running?
