General Supercharger Thread

Yes, we just did it on my old man’s truck and I’m moving to it from my maggy here shortly

 

Any chance if something broke free, or got tangled up, when you added gas? It would seem like something physically shifted once the tank filled up if it was fine before that.

 

I think it was coincidence. I erred (too bad for me) on the side of caution, not wanting to clamp down too hard & possibly cut the line on the hoseclamp at the pump. It slid off when I opened the basket so I can only hope that was it. I made sure it was all the way down & gave it more pressure. The full tank allowed a slew of gas out when I opened the hatch so after cleaning that up, reassembling the basket & dropping it in, I'm cleaning gas of me having some coffee then I'll go back out & see what is up. Hopefully, that is it, I ordered a foot of proper hose from Napa in case I need it for pickup when they open at 9, hoping not to need it, thieves are charging 50 bucks!

 

Back to having pressure. I need to button it up. Hopefully for the last time.

 

Butond up, lost fuel sender GAAAAAAA. I know I connected it but apparently not tightly. Not pulling the tank again today, it is full, I'll fill it in 200 miles if I don't drop it again before.

Going to pick up the 50.00 hose & see whats what.

 

Went to Napa for the golden hose, the truck is amazing!

It’s over 60lbs fuel pressure at all times, goes up in boost, went down to 8.7 (that I saw) afr & peak boost 9.4 It's not bogging, feels amazing and apparently I never really felt it the way it shoud be.

0 & the fuel gauge decided to come back to life.

 

That is good to hear, glad you got it sorted out.

 

Don't forget to RMA that 450, see if you can get your $$ back, tell em to shove it!

 

They refused to take it back, they said only replacement. I said no, I just want to return the defective pump. This went back & forth about 3x I said I'll dispute it. & I did.

 

Anymore insight into why your truck shit its cats?

 

Talked to a few guys on Boosted Tundras FB and was told it's common due to a rich tune lol

 

Thank you.
In terms of AFR how rich is rich if they've discussed it?

 

I'm seeing low 10's for WOT afr. Couple guys were saying they go through multiple cats a year

 

Jeezus. I've tuned mine for ~10.8, time will tell. I guess it's cats or engines, huh?

 

Weird haven’t had a cat issue (fingers crossed). And I’ve done some long pulls

 

What cats???

 

I'm just looking for an excuse to get LTHs.

 

Found mine! I need to figure out the cel issue once cats are deleted. Prospeed won't tune the light out for me due to epa

 

I'm sure someone here can help you with that.

 

Yea I've done like multiple minutes on end where I'm in boost (or near boost) towing up a hill and it's just chugging at 10-10.5

 

cat question...
How does the ECU know there are cats present?

It's a dumb piece in the exhaust path.


and...what are the symptoms of damaged Cats?

 

Pretty sure the reading difference between the 1st & second set of O2 sensors.

 

Regarding symptoms I experienced..

CEL came on after I hit it at a stop light and looked in the mirror to see a cloud of white smoke/dust. Proceeded to get on the freeway and the truck didn't accelerate when I gave it ~75% throttle. Got to work and I heard the fronts rattling followed by both my tail pipes almost clogged with the honeycomb shit

 

Yeah, some say that it can cause engine damage if the exhaust gets blocked by the remnants of the cats.

 

I read that too.. truck still feels down on power as I couldn't get the driver cats out myself so I banged on them pretty good and the remnants are continuing to blow out. Going to baby it until I figure out a muffler to tie into the trd cat back. Arh headers are ordered

 

If it happened to me I’d likely just remove the midpipes and clean the remaining guts of the cats out and then address the codes either via tuning or O2 sensor spacers, etc. but that’s just cause I don’t want the expense of headers right now.

 

O2 sensor spacers?!

 

Something like this, moves the sensor out of the exhaust stream, kind of tricks it to thinking the cats are still there by getting reduced readings:
