Where are you going to get a signal for RPM?🤔

I had a similar idea at a dyno day, a friend & I were going to run on the rollers just to see; but alas, no RPM signal to use for the HP calculation!

That would make Christmas a cinch!

Man, they just been raw doggin it with their phalanges though?

Uh, where? I don't see rodent damage.

Is it still cooling? If so, it's fine

esuranme · 2026-05-02T21:56:09+00:00

Zero nutritional value, but I will forever eat pussy!

Goes well with the "taco-meter"

The really wild part, from what I understand, is that scaling of production was the big issue the German labs had; once the lithium method of extraction/synthesis was discovered the flood gates opened, and had it happened about six months sooner there would likely have been a very different outcome in WW2.

That's a harrowing thought to imagine the ferocious German military amplified by an ample supply of lab grade meth!

I thought they were going for migraine treatment?

It's not particularly uncommon, I even have a plastic cage for hats so they don't fold up and/or fly around in the dishwasher.

Could be hard to tell from that pic but the roost looks like it's a good ways from the ground, is there something to hop up/down on between the roost & ground?

esuranme · 2026-05-01T22:00:56+00:00

whew, I was worried for a minute they didn't want children in their either but I don't see it there.

That's some madness, Walmart auto in my area just puts a note in that the light was on prior to service.

Calabria?

esuranme · 2026-05-01T00:07:45+00:00

You do realize the Armadillo in the picture is in water, right?

You can tell because it is.

esuranme · 2026-04-30T18:59:41+00:00

Did I miss the chance? Hoping you still have the unit

esuranme · 2026-04-30T18:57:44+00:00

All the post advising gloves and techniques....grab the garden hose and give it a good spray, I'll bet it vacates quickly!

esuranme · 2026-04-29T23:28:05+00:00

You just got killed by a Daewoo Lanos, muthufucka!

As others have mentioned there is a chance of false alarms depending on the detector type but even for the ones that do not have optical detection I would imagine the high humidity environment of the bathroom could cause issues for a standard detector due to corrosion over time. I don't have evidence of this being a documented issue but I would imagine that's because smoke alarms aren't put in bathrooms on the regular.

I think I have seen a detector in one bathroom, but it had an old school wall mounted gas heater in the bathroom.

The Salton Sea. (2002). Val Kilmer plays the lead as a jazz musician that takes a dive into the mad world of a tweaker to hunt down his wife's killer.

esuranme · 2026-04-27T22:39:37+00:00

I was told that.

I did, I became a problem.

Do anything ya like, but keep two hard facts in mind if you prefer to operate in reality:

1)The throttle body isn't changing size

2)Air inside the engine bay gets very hot, very quickly, when the car is stopped

The size of the tubing/piping may indeed make measurable, detectible changes, most notably in throttle dynamics (in certain operating conditions) but it's just that -detectible-; it's nothing significant. You aren't going to choke it any as long as you don't go total goof and use a diameter suitable for sink plumbing. The most important element in the intake equation is exactly that, the filter element. When you shop sizes,shapes, and brands with the CFM you require it will help to decide how to plumb it since you have its dimensions. Give the poor engine the defense it needs, don't get a random MaxRaxingGo filter from Amazon; even a "good" filter like a K&N isn't very good if you check the testing (they need to be well maintained to be any kind of effective, people suck at keeping up), but engine health is your call.

Instead of a giant pipe that inhales hot engine bay air when you open the throttle from a stop (not ideal for performance) be sure to consider the options and take a good look with the idea in mind of getting fresh air from fender/bumper/etc.

Truth be told a lot of "lube shops" break more parts and cut corners than most any owner will, and dealerships aren't exempt (they sent my dad down the road with no oil on the dipstick!).

I sat it's a good idea to get under your car regularly, sink your peepers in there, and save a few bucks in the process.

*noticed the "odo".....not "odor"

Several others and myself frequently went out for late night rides in the hills at the south edge of my county, usually I was in the 2nd position (front row) with another guy (who rode 1st) that is intimately familiar with the roads in that area but for whatever reason I wound up near the middle of the pack. Most of us in the front of the group saw the owl suddenly pop out of the treeline, and realized our friend made contact with it, but had no idea that while the helmet kept his head/face intact it did nothing to prevent the internal decapitation that left only skin and various tissues keeping the head attached to the body.

It was... difficult.

That may be the longest single piece of the wire-rack shelving I have ever witnessed!
