Powershift posted:top truck challenge 2014! I am actually legit impressed by most of the trucks in TTC 2014. The previous years have been a bunch of banjo-playing, sister-loving rednecks for the most part, you know, the sort who think that body lifts, giant leaf spring lifts, and 44" gumbo monster mudders on an F350 is the pinnacle of off road vehicle construction. Glad to see some real functional well designed suspension this time around.

Torn Quad Jones posted:we have reached maximum bro truck! loving awful. Those are *probably* one of a few axles - rockwell 2.5 ton, rockwell 5 ton, eaton fuller heavy OTR axles, or a variety of loader and military spec axles made by Eaton, Rockwell, ZF, and a few other companies. They're widely available parts wise and sometimes even come stock with selectable lockers... and ARB and other vendors produce aftermarket lockers that can be installed pretty easily too. No excuse. Also, that suspension is loving awful by way of having about 2-3 feet too much lift. The control arm angles look pretty decent by mega truck standards, in fact the LCA angles are excellent, but the upper control arm lengths are shorter than the lowers which will result in pinion dive when the suspension compresses. Also the rear UCAs appear to slope upward to the diff end rather than being mostly parallel to the LCAs. I fail to see the point of putting that much lift in a vehicle only to make a monstrous jungle gym of a subframe that completely negates the increase in ground clearance.

Timage posted:Since there was a moment when the Jeep was stationary, would it have helped if he shifted into reverse and dropped the clutch? Obviously you'd need amazing reflexes but would it have saved the car if it was heading for a flip? Yes, but then you're going backwards in reverse and probably aren't looking where you're going. Better response probably would have been to stab the clutch and let it roll back naturally, then brake gradually. In fact, this is a perfect example of why I prefer wheeling a manual, because you can do that. I watched a friend go through a harsh triple roll because he was frantically fighting with his ratchet shifter trying to get it into neutral.

wolrah posted:I was always under the impression that ideally you want to do dyno pulls in as close to a 1:1 gear as is available. Obviously sometimes uncooperative automatic transmissions or speed/torque limits of the dyno prevent this from being a viable option, but it seemed like that was a "if you can do it this way, you should" type thing. Is that not correct? You typically want the direct gear because it reduces transmission losses to a bare minimum (since direct gear is usually just a synchro connecting the input shaft to the output shaft and the gearing that drives the countershaft and all the mainshaft gears is just along for the ride) and gets you the most accurate dyno reading possible. Usually on a 4 or 5 speed manual that means 4th, with autos it really depends.

I know you're mostly a Subaru guy and Subaru 5MTs are wacko territory and don't work like what I said, so I'm not gonna be a dick, but all RWD/4x4 mantrans I've ever worked on (NV4500, NV3500, NV3550, AX15, AX5, AX4, SM420, NP435... etc) work how I said they do. The input shaft and output shaft are collinear in MOST such transmissions, so (for example, in an AX15) when you engage fourth gear, you're just sliding the 3-4 synchro collar forward over the 4th gear synchro stop ring onto the input shaft's rear end end, so it links the input and output shafts directly. And yes, like Enourmo and I said, the input shaft's drive gear, the whole countershaft, and the 1st/2nd/3rd/5th counter gears and such are all just along for the ride, but since they're under almost no load there's not really much parasitic load. I'll see if I can find a good video on youtube, actually, seeing as this is the youtube thread  e: here's a Toyota R150, which is the same thing as an AX15 in every way except the input shaft, output shaft, tailhousing, input bearing retainer, and shift turret. https://www.youtube.com/watch?v=vOo3TLgL0kM e2: 14:15 or so in is where 4th gear is covered. kastein fucked around with this message at 23:56 on Nov 24, 2015 |

And here's a video on how synchros actually do their job, since it's widely misunderstood: https://www.youtube.com/watch?v=MXsRfbOiBhE And here's how a crazyass folded-in-half Subaru 5MT works, which is why anyone who's used to Subarus and AWD Audis has a different worldview of the internals of a mantrans: https://www.youtube.com/watch?v=4Ca5Muoz1fs The front pinion gear shaft is actually INSIDE the output shaft. The input shaft is on top, all the gears drive down off it onto the output shaft (the outside layer of the lower shaft), which drives the housing of the center diff. The side-gear of the center diff that faces forward drives the front differential pinion gear directly through the center of the output shaft, while the rear side-gear of the center diff drives a set of helix gears that drive the rear output shaft of the transmission. e: It's kinda mindbending to me as a RWD/4x4 transmission nerd. Actually, really mindbending. It's also why Subarus don't have an exact direct gear - you should never design a gearset so the ratio is an integer since it'll wear the teeth unevenly (as each tooth always contacts the same 1, 2, 3, 4... teeth on the other mating gear) so Subaru "direct" gear doesn't link input to output directly, nor does it have a 1:1 ratio. e2: also note that the 1/2 synchro assembly is on the output shaft while the 3/4 synchro assembly and 5th synchro assembly are on the input shaft on the Subaru trans for packaging reasons. If they'd just put the 3-4 synchro assembly on the other shaft and left even a little bit of space between the 2nd and 3rd helix gears on the output shaft, you could build a girdle with bearings that would hold the input and output shafts together in the middle of that space, which would prevent shaft flexure way better than a case girdle and prevent the gears from going out of mesh under load and producing the well known 2nd and 3rd gear Subaru 5MT failure. kastein fucked around with this message at 00:16 on Nov 25, 2015 |

The guy isn't describing it well - the gearset right at the front isn't involved in 4th gear. Those two gears are how the countershaft gets driven. The gear on the input shaft next to 4th is permanently fixed to it (in fact it's machined into it), not being engaged by the synchro. I've been meaning to do an AX15 teardown/rebuild video for NAXJA, maybe I should do it soon. It's pretty obvious when you're holding the pieces in your hands what's going on, but the video can be confusing. e: this is all one piece of metal, the synchro cone is sometimes pressed on but the gear's integral and machined from the same forging as the rest of the shaft:

A regular washer spreads the load and allows the fastener to tighten better without galling the surface. Which is why I really like to see washers on cylinder head bolts, especially alloy cylinder heads. This is also why a grade 8 washer is important if you're using grade 8 hardware and torque specs. If the washer deforms conically and only contacts the part directly under the bolt head, what good is it?

Fo3 posted:Looks cool, but I don't understand their point. They are saying other fastening solutions relying on friction are bad, that theirs doesn't rely on friction, but IMO it does. No it isn't. If you watch the video, Nordloks are designed so that the slope of the ramps is actually higher than the slope of the threads, so if you try to back the bolt out, it increases the tension on the bolt, not mere friction.

I'm really split on this video. It's got some really cool stuff and also some incredibly hick poo poo in it that no serious engine builder should be doing. And it's not like they're fooling around with cheap poo poo, either, that motor is like 100% super-expensive aftermarket parts. https://www.youtube.com/watch?v=xJFYw-Ykxu4 Hackfab poo poo: - fat dude #8 smoking a cigar over the motor being assembled, I guess cigar ash improves ring breakin or something - hey we're halfway through assembling this shortblock, let's deburr some things on the head gasket surface of the block now and just drop the shavings into the lifter valley gently caress it who cares - dude loosening and retightening head stud nuts uses the drat torque wrench as a breaker bar, then immediately retorques with it - apparently these guys don't know how to calculate the correction factor for their torque wrenches when using crowsfoot sockets? - tiny bead of sealant around water ports on head gasket looks like it was applied by a parkinsons victim - putting pistons/rods into the block: fumble that poo poo in there with no protector wrapped around the big end of the conrod, send a dude under the motor to get it lined up with the crank, then he fumblefucks around with the bearing cap and nearly scratches the crank journal with the bolts - demonstrate the lifters by fumbling around with them and repeatedly jamming them into the lifter bores dry/misaligned - clean parts off over the open motor you're about to put them on  Amazing stuff: everything that isn't hacky. I'd give my left nut for that motor. I'm not arguing with their results, but seriously, I take more care than that assembling a shitpile junkyard-sourced EJ22 or jeep 4.0L in the woods behind my house. What the hell?

Agreed. If someone finds an open source or reasonably priced way of tuning Mopar motors (short of sending an ECU and money to some asstard with a copy of SCT Tuner who throws a canned tune on it and ships it back) I would be more interested. That being said, I still have two mopar motors to put in jeeps. Just... sadly at stock power levels/etc.

Enourmo posted:That ranger is a completely different line than the one north america got though the loving pile of poo poo one I've worked on for my family (dad DDs it) has convinced me to never buy a ranger. Why: 3.0L V6 in a freakin 2001 model year vehicle that gets worse fuel economy, less power, less torque, worse throttle response, and less reliability than a 4.0L jeep motor from a full decade earlier full-framed vehicle, yet has worse rot problems than, again, a jeep truck from a decade earlier (with the exception of the cab floor. For some reason, that isn't rusting on the ford.) IFS that inexplicably rides like a horrible lumbercart, even compared to, again, a solid front axle jeep truck from a decade earlier incredibly poor visibility ... and a higher price I guess it probably scores higher on crash safety...? they're both mini pickups, you're going to die in a serious accident. e: here's a video of one with accident damage having the back half of its frame cut off and replaced in under 2 hours by 3 shop workers. I'm somewhat worried about them oxy torching everything apart since if you gently caress up doing that, you can put a hell of a stress riser in the frame... I like to see rivet heads ground off instead. But at least the frame is riveted together in the middle so they can bolt/rivet it back together after instead of you worrying about whether the guy behind the welding gun knew what he was doing. https://www.youtube.com/watch?v=cudfDsz7CFI kastein fucked around with this message at 18:13 on Mar 4, 2016 |

I mean the 3.0L Vulcan V6 and the 4.0L V6 in the 02 USDM Explorer that has 3-4 timing chains, a balance shaft, and a jack shaft, all so that they could use the same cylinder head casting on both sides. It hosed him right hard and good and he ended up with a last-year 302 secondgen Explorer to replace it.

A large number of them are stolen. I'd rather see them returned to their rightful owners, TBH. Lawless dirtbike/atv troublemakers are becoming a serious problem in some cities though. Boston just started up the same sort of thing, they are mostly unregistered, uninsured, ridden like absolute dickheads, by absolute dickheads, and they're more than happy to run from the police if anyone even bothers to try pursuing them because they know a cruiser can't keep up. Quite frankly I'm surprised they managed to seize that many.

Civil forfeiture is absolute bullshit. Then again, it's a different issue from seizing the cars and bikes and ATVs of lawless fuckheads and teaching them a lesson. Not sure quite where I stand on that, especially if they aren't convicted. Youtube search for "boston bike life": https://www.youtube.com/watch?v=kfFCx69P7oI https://www.youtube.com/watch?v=YWdJNoOZqDU https://www.youtube.com/watch?v=AMsdw2IrSfE https://www.youtube.com/watch?v=AdkWbtyAmPE Here's a great example, those honks are frustrated drivers who are being blocked by a giant group of "bikelife" douchebags, they only disperse when the cops are on the way: https://www.youtube.com/watch?v=4uHzyieFhDw https://www.youtube.com/watch?v=yCLXau1vrR4 "New York bike life": https://www.youtube.com/watch?v=L-8QfpdlfEw 1:20 or so, there's a great example of why this poo poo should be shut down, a biker and an ATV collide when they almost rearend a squadcar with the lights on. 3:40, a "do not chase" tshirt, clear sign of a responsible operator: https://www.youtube.com/watch?v=09axl-GVIuY https://www.youtube.com/watch?v=q9ci06BzA5g Police arresting one in Atlanta: https://www.youtube.com/watch?v=zeP5cTvDqRc Wrecks, hit-and-runs, and police chases: https://www.youtube.com/watch?v=9oo-W3edSz0 more wrecks, more police chases, what looks like a really nasty compound ankle fracture at like 2:30: https://www.youtube.com/watch?v=9vR9UBKdaG8 Miami, gun stuck in someone's pants at 2:20, soundtrack is a great example of what's wrong with this too: https://www.youtube.com/watch?v=Eo56UBLBQ7I Wheelies everywhere, burnouts, no safety gear, no registration, no insurance, incredibly unsafe operation in general, running red lights, blocking traffic during green lights, riding in the bike lane, going the wrong way, crossing the double yellow, sideshows, you'll see it all. In a few cases dirtbike/atv gangs have decided they own the road and caused accidents with a car, then chased them down. It's like a cross between GTA and Mad Max and it's really not OK. It does look like a hell of a lot of fun, and there are some pretty skilled stunt riders involved who do some cool poo poo - if no one else lived there. Seeing as they're loving up the roads for literally everyone else in the city and not only don't feel bad about that, they're reveling in it, they can go straight to hell.

It's way cheaper for the town to let retards run into their guard beam (they never even hit the bridge - saves on bridge safety inspections post-crash) repeatedly after warning them a few times, because the retards and their insurance companies pay for that. And yeah sewer lines and railroad bridges are not easily moved and even without either of those, this would likely be a several million dollar construction project. Construction in the middle of a town is not cheap.
