What did you do to your S550 Mustang today?!

[shogun32]

This is my first catch can so no clue if it's a lot or normal. I will say I notice zero difference in how the car operates. The supposed robbed HP from blow by doesn't hit my butt dyno at all.

This is the first I've ever seen people claim about blow-by being an influence on HP. The reason to capture is to keep the intake and the valves clean, nothing to do with "power" as such.

Hold please. Looking up the sellers page where it says it...or realizing I'm crazy yet again.

Found it.

Your 2018-2021 GT Mustang has a PCV (Positive Crankcase Ventilation) system that directs the pressure from the crankcase vents back into the intake system. This, unfortunately, allows oil vapors to also pass through and collect in the intake tube, which can result in dilution of your gas and decrease the octane in your fuel, which can affect your Mustang's performance.

right, but that's just marketing jargon. 18+ cars are DI, and whatever minor "dilution" from Port-FI might occur is extremely minor at best. coking up valve backside is the more "relevant" concern.

So basically, a catch can would actually hurt your Mustang performance IF you used high octane oil.

Drove to work and 10 minutes in I get a service advancetrac notification and ABS light goes on. 5 minutes later I get the wrench notification engine sounding weird sluggish has trouble over 3k rpm limped to work and unplugged the battery

At lunch reconnected negative terminal got service advancetrac notification, abs light, and hill start assist unavailable. Drove around 5 minutes everything went away. Turned off, ate lunch, restarted and no more lights

Gotta clean the battery terminals AGAIN tons of green and white powder screwing with the connection

I will say the oil collected is really great looking. The weeds seem to like it too. So basically you're just prolonging the need for a walnut blast. Should have put one on my Mini.

Today I converted my never used Gorilla lug socket into a strut top nut tool.

Took me about 100 minutes as an unpaid tool grinder. Again, clearly I have too much time on my hands.

I was curious if you had copper terminal connections. The copper reacts when electricity passes through it and creates copper sulphate, the white power we see at the terminals. Try changing the terminal connections to a non-copper metal and that should stop the acid build up unless you have a battery problem.

Excellent description of my ex wife ..................... She suffered from extreme blowback.

Went to kick off meet in Myrtle Beach Monday. A big turnout.

Are you going Friday?

 

[Tang]

Exact same sequence (service advancetrac > check engine) happened on the drive home so I dropped it off for service not optimistic about it

Walking around the different events at Mustang Week and thinking how vanilla my car is.

What'd you do, just chop the end off and weld a spare bit onto it? I'd like to do this, hah. It's such a pain to juggle the tool and the sockets.

 

[Konamoth]

Not today (again...) but threw on a set of wheel spacers to fill out the fenders proper. 25mm in the front, 23mm in rear. No rubbing, no added ride harshness—while it's likely placebo, it does feel a bit more planted. Admittedly, this is for looks alone though.

Pics!

After:

It's just covered in morning dew in this last pic—I'm not negligent, hah.
