To see better at night you want good light far down the road while minimizing the foreground light. So those fog lights might make everything seem brighter but that light is not going anywhere useful and actually hurting your night vision.

That said most fog lights are pretty useless and mostly for decoration. There are cars where they just come on with the headlights and you can't really notice if they're on or off. If you want actual useful fog lights in fog you generally need to buy them on your own and they're only any good for going very slowly with poor visibility.

The slot is there so they can use the same pitch stop and mount on the trans between the regular legacy/impreza and outback/forester, which space the subframes, suspension mounts, and drivetrains down.

Also "a 14mm" wrench doesn't tell you the thread pitch and unless the hardware store has JIS fasteners there won't even be any of that size.

No, the safety sensor is on the clutch pedal.

As far as I know most transmissions neutral position sensor.

The problem is not just leaving the car in neutral though, it's actually installing a system to use the neutral switch. Years ago working at a shop, I moved some cars out in the morning, obviously parking them in gear. Later that day, another guy goes to pull one back into the shop, uses the remote start, and sends it right into the bushes.

See the little window underneath the nose of the aircraft? The frame holding the glass panels is composite. It's no thicker than a pencil but handles the aerodynamic forces at Mach. It's tremendously strong but still smaller than most of the failed components on any of the examples in that video. I guess they use cheaper materials.

Most of those are probably from crashes and hard impacts and stuff. Failures while "just riding along" is pretty rare. But there are a lot of cheap/knockoff carbon bike parts floating around too.

This guy cuts apart a lot of carbon bikes and parts

A lot of cvts have paddles so you can pick preset ratios and will fake shifts.

Plus people tend to seriously underestimate the aerodynamic forces. I learned that lesson when a few splitters didn't hold up so well around the banking at cal speedway.

They're diesel pistons, and they're very broken.

Not really because then there are discrete exhaust gas pulses going into each turbine vs a smoother, more continuous flow when they are all combined into 1-2 collectors. Plus, generally I want to say that one single larger turbo is more efficient than two smaller ones at the same total airflow and pressure ratio.

E- multiple, smaller turbos tends to be better for response and low-mid range power but that's not what these things are going for.

The whole point of the solid white line between carpool and regular lanes is so you can get in/out of it wherever you want vs having a double yellow and designated entrance/exit points. Phoenix vs LA for example. It's also common for a carpool lane to be a regular travel lane during non-peak times.

The real answer is that almost no one loving pays attention to what they're doing when driving.

The time attack car i used to work on didn't have a bov.

so that chirp between shifts is surge. Turbo is a gen 1 gtx3582, think peak boost was 38psi and it made 747whp?

The engines blew up a lot but the turbos seemed to hold up fine. To contribute to the thread this happened the next morning on the first hot lap

I thought it was funny.


In real life with a non-synchronized transmission in a race car you still wouldn't double-clutch the upshifts btw. Downshifts probably.

A couple years ago i got charged by a black bear with cubs and yelled at it and it stopped, so that's an option sometimes. Have also had my loud mtb brakes scare a bear away on two occasions that I know of. A number of other times they've just ignored me/us and continued eating berries in the bushes. The other day I saw a bear and actually had bear spray in my frame bag. Heard rustling in the bushes above me on a road, look back, and a bear comes down on the road, then runs off the other way. That made 3 sightings in a week.

50 years ago, there were more sticks, as I recall. But even if not, as rndmnmbr notes, the air- or electric-shifter splitter and range boxes won't shift while there is still torque applied. There's too much mechanical force. It's not really the computer doing it, it's physics.

edit: At least, that's how I understood it.

Yeah you can experience this yourself. Just try to pull the shifter out of 3rd or whatever while you're accelerating. It's not coming out. Then let off, and it pops out of gear.

Driving something like a manual sequential dog box that's a good technique. Preload the lever so when you lift or it the rev limiter it shifts to the next gear (and yes I've actually driven one). You can even use a strain gauge on the shifter so that when you pull hard enough it cuts throttle and lets you shift.

In my experience water pumps tend not to last as long as two timing belts.

The outlet of the water pump goes directly to the radiator, yea?

Usually the radiator goes directly to the water pump inlet.

You guys should hear about how the mzr timing gears are held in place.

It's just from the bolt being tightened.

All the ones i've used had a big ball valve on the top of the tank so you raise the drain pan up above the valve, close it, and then apply shop air to push oil out the drain tube. Looks like maybe that ones doesn't have a valve so he needs to raise the pan way up and then be really gentle with air pressure to keep oil from spraying out the top?

I don't even like torqueing the lugs with the full weight of the car on the ground, I'll lower it so the tire is just touching and won't slip.

Oh, that reminds me, I noticed a broken off stud with a lug nut on it on the road at a light on a bike ride the other day.
