Maybe not too much power for me, but too much power for the car.

At what point is the depth of the jank so deep that it becomes a better solution to rip out the entire harness and start fresh?

Around firms making predictions about auto sales patterns, the fact that new car demand was going to cool off has been known for a while...the somewhat hairy question of *when* that would start to affect sales is a lot more difficult to pinpoint with any accuracy. It was similar in energy...we all saw the writing on…

As the original comment states: “Context, sampling mechanism, and research design means everything.” The example was meant to indicate that a sample of 1000 out of 500,000 is as valid as a sample of 1000 out of 300,000,000. The argument about geography is a strawman because, while it delves into the nitty gritty of…

If the question was about visiting Wyoming, then a sample of people in Wyoming wouldn’t be random in the context of the question. The original point is right not only for a reasonable definition of “sample” but also for a reasonable definition of “random”.

Generally speaking, strong results from a company don’t move the stock price unless they outperform their own projections. Companies with big fixed costs don’t have huge bumps in earnings seasons because, barring a 2008-level catastrophe, they don’t deviate from their own earnings targets either up or down in a…

In retrospect, yeah. The power mods that weren’t mentioned in the article are way more of an issue, and the CAI itself, fouling the MAF or not, is not a good mod for turbo Subarus.

It’s a K&N, they all use oiled filters.

It’s less direct spray or flow, and more that eventually the entire intake tract gets coated in oil. That said, it’s been pointed out to me that the car’s running a full K&N CAI, which is almost certainly the actual cause.

Yeah, once I read the ad and saw the guy had an intake, that was the more obvious conclusion.

After reading the ad I came more to the conclusion the MAF probably died as a result of the CAI.

The BMW is stock, other than the wheels.

I read the ad and the owner had put a full CAI on the car...MAF fouling was most likely caused by that. The tune, TBE and other power mods also make this just another janked Subaru, spec.B or not.

The MAF dying at 85,000 miles is a symptom of something else, not a cause into and of itself. The oil in the intake tract that causes the MAF to fail is also a symptom, where the problem is oil seals in the turbo (though turbo Subarus get some oil in the intake normally, but not enough to kill a MAF sensor) or other…

A full CAI on a turbo Subaru is a worst case...if not tuned well these could cause serious engine problems and are generally not good mods for making power. Reading the Craigslist ad the engine is much more modified than this article let on, so my assessment is even worse.

Yeah, this time I went and read the ad...not just a panel filter, but a K&N Typhoon! Ugh...CAIs do *not* work well on turbo Subarus. Beyond that, the power mods are much more extensive than noted in the article. I wouldn’t touch this car at any price without a doctor’s note from the tuner who wrote the “custom Stage…

Excess oil routed back into the intake system via the PCV valve. When the turbo oil seals start to go you get not only oil in the exhaust but also oil in the intercooler tract that gets picked up by the PCV system. It happens in all turbo Subarus to a degree, but it gets much worse when the turbo oil seals begin to…

That’s true, I forgot about just having an oiled panel filter. Nonetheless, because so many of the turbo Legacies had turbo oiling issues, that’s still my first guess.

Best case scenario the MAF was fouled by oil blowby, meaning this Legacy is about to have the turbo problem most of them did. Budget another $2-3000 for a stock replacement.

Mustang dynos tend to be more conservative than other brands and calibrations. As it is, you can’t really compare two cars across dynos, the external conditions and software differences are too great...for before/after, though, they’re great.
