LSX454 swapped 95 BASS burb.

Little lower, little cooler, bigger sounds.
.... :thinking: :whistle:

No.... Couldn't be..... :rolleyes:.

Seriously, I guess it's possible. Lol
 
What could have possibly vibrated that nut loose?

That’s intense if the subs caused it.
 
My engine vibrates everything loose, your stereo does the same. The loudest system I ever built was only about 140db, I'm guessing you're way beyond that.
 
I'm guessing not tightened correctly.
It's a castle nut, the type with the top pinched a bit to be like a locking one.

Admittedly, it IS on a slap shifter. So that could have helped it go bad. But I wouldn't have thought this soon, since a don't slap shift unless I'm doing 1/4 mi, or 0-100 runs.
Off which I haven't really done many this year.

But... As stated , the stereo has caused a few issues too lol.
Swapped a bunch of nuts for brackets and suck like exhaust, etc. to Nyloc style. Because a few things have come free.

Between that, and RTV as loctite, think I found most of the places it was happening.
 
It's the castle style from all Ive seen.

And really, I would hope I'd only need to tighten it once lol.
But, here I am, planning to tighten it for a second time.


In the vids I watched, putting a bunch of them head to head. The nylocs were best overall.

They just don't work in every location.
Like probably submerged in oil, or as a header stud nut lol.

Started the process of finding them because I kept vibrating exhaust hangers off the frame.
Lock washers on the 1/4 and 5/16 bolts weren't cutting it.
 
Now, keep in mind I have 300 or more pounds of sound deadener on the panels of this thing, every surface that's flat ish on the entire inside.
And added latches top and bottom of the barn doors pulling them tight down into the seals.

And that song is all lows. It doesn't even get into the higher buzzing bass.
 
This part was easy.IMG_20261003_234239138_HDR.jpgIMG_20261003_234218938_HDR.jpgIMG_20261003_234101749.jpg

But.... This part, sucks. :notworthy:

I lose this MFr it'll get an 8HP or something next round.
Won't be doing a 4l80 again I guess.
Just don't seem to be built for high HP launches in 6000+# vehicles.
 
Not sure where all the brass came from? But I'm sure it's not supposed to be in pieces in the bottom of the pan lol.
 
Double checked my dipstick while the pan is off.
Setting about 1/8" above the lip.
Easy enough to use that.IMG_20261003_235013801_HDR.jpg
 
I think we should email these pictures to the builder and see what he says.

It may just be a bushing wasn't quite under flush and it clearanced itself, and now its done. Or it may mean that something is going to go out.

You said its brass? It doesn't appear to be stuck to the magnet.

I’m with him on this. No way I wouldn’t try to warranty it. I’ve seen 4l80’s hold up to way more power and abuse than you are putting it through.
