(Their general answer to that car is to take a rando cheap engine, add a giant blower, and see how long it takes to blow up. Note that none of that involved work below the valve cover gasket.)

Only reason the Rotsun keeps coming back is everyone wants to see them suffer to do stuff to it since it was unsavable when they got it with all the rot.

MadScientistWorking posted:There is something entertaining about them taking a hunk of junk like that and seeing how much power they can generate. That's why I like Sloppy Mechanics and all the power they get out of turbo'd LS junkyard motors. They don't have the budget of Roadkill though.

Even as a civil engineer that has taken classes on pavement mix design, I'm always amazed at how catastrophically a road can fail in hot weather.

In places where the heat actually starts to soften the asphalt. Concrete's fine. Asphalt turns into a nasty sticky mess when the temperature's in the 40ºC range for a week or more. People driving fast actually move it all around and I know many places where you get waves in the road from acceleration/braking. I've never seen a road tent up like that from heat, though. That said - I've only ever noticed it in cities and other busy areas. In quieter areas, like in the actual outback where it can be 40º for weeks, I've never had problems.

This happened on 94W in Wisconsin close to the MN border, less severe but the same effect. July 4th weekend the road heaved right before an overpass, leaving maybe an 18" hill of buckled road. Luckily being right before an overpass there was an exit 50 yard before the buckle and traffic just got off and back on the interstate.

MadScientistWorking posted:Is the issue with the Rotsun that whatever ancillary stuff besides the engine just not capable of handling the power? The chevy 4.3 made power, but had massive lag and kept breaking the motor. The new ford 5.0 makes massive power, seems happy doing it, but now breaks everything downstream. Expecting a T5 to hold up to 550 hp and 600 ft-lbs of torque was a loving joke, so naturally it broke bad on the second drag pass. The Subaru diff with 3.90 gears will be next to go, if the axles don't act like fuses in the driveline. If they want to do it right, a TKO500/600 and a better rear end situation will fix it. But that won't happen.

I'm trying to remember the roads when I lived in the Mojave and I feel like there was way more contrete than the east coast. The only roads made of concrete in the Phoenix area are the interstates. Asphalt is just so much cheaper to put down, that no municipalities use concrete. Most of our interstates/freeways in town are concrete, but they cover them with rubberized asphalt... so nice, smooth and quiet.

The asphalt does heave down here, too, but it's not as noticeable due to the replacement schedule. The biggest place to notice it is where asphalt meets concrete, like at an overpass or underpass on surface streets. You'll get a dip or a bump from cars dropping a bit from the concrete-asphalt transition, which compresses the asphalt into a trough, which makes the drop even bigger, etc in a feedback loop. You'll also get a wave/bump on the asphalt-concrete side from cars braking for stop lights. The underpasses for Mcdowell and Thomas where the 51 goes over are the biggest examples I can think of RN, though they just repaved McDowell.

I haven't noticed it in cars with stock springrates, but once you get into track car territory it seems like you get feedback loops that lead to vibration on the repaved area of the 101 and some other areas. 101N starting at 202 interchange up to like Thomas comes to mind first.

An IR thermometer in Death Valley is the best, I recall the pavement temp being somewhere in the mid 60s.

It is almsot like they formulate asphalt mixes for the expected temps of the area.

They tested a big chunk of the ring road in edmonton with concrete and ended up replacing most of it 3 years in a row. My old dodge used to hit a harmonic frequency with the shape of the pads and start bouncing.

Think i found out why my rear wheel carrier was difficult to open and flopped around like a soft dong... And i think i found out what the pivot point was once the bearing siezed solid...  Theres a retrofit kit from ARB that replaces the tapered roller bearings with a pair of sealed flat roller bearings and a spacer tube. Except it took nearly two hours to get that loving bolt out after it galled in the nut.
