Turbo Technics S280

[wetwea33]

Still leaning out a lot up top.. Surprised that AFR isn't flat across the pull.

I'm hitting like 12.1 past 6k that really isn't lean but it's still not my final tune I'm sure it will get cleaned up once we add some more boost.

Just surprised to see it trending that way on aux fuel. From working with different tuners, my experience was always they start rich on the aux fuel and then rely on the STFT of the OEM ECU to take out extra fuel to hit an 11.5-11.7 target.

I get that but we added in some boost up top for this revision and it's a working progress and the weather has really varied here recently and the da is all over the place.

Vdyno from my latest revision on 93/aux

did you hit the rev limiter?

 

[wetwea33]

Yes but I remove that data from my logs for vdyno

I've always found that even if deleted it still makes for a wonky graph. Still really good spool and tq

 

[wetwea33]

For doing logs it's good to get redline data. Once it's finished I'll try to stop right before it to get a clean graph.

If he really cared enough, he would invest the time to take a video for us and post it up here rather than trying to describe a noise over the internet in less than 10 words..

Well here is the video

View: https://youtu.be/-1JHfLA4ep0

around 7 or 8 seconds when i give it the beams is the sound i am hearing
intake: ramair crossover - silicone elbow - s200 airbox
exhaust: whoosh catted - stock exhaust
14psi gate
I have triple check for leaks, no leaks
Something tells me is the exhaust that is so restrictive, or idk, whatever
like to hear your opinions, thanks

That honestly doesn't sound super normal but it's definetly not the exhaust. Almost sounds like metal rubbing on metal.

Sounds like a your turbo is failing to sneak a fart.

I know, don't know what to look for

I have run 1k miles since install, did an oil change, the oil looks spotless, super clean. No leaks, no white smokes, nothing rubbing, etc
only thing i could think of is to put back on the stock bov and see if the one i have on is leaking boost, sounds plausive. if it was the turbo bad, it would had granneded by now with 1k miles on it

yeah, alot like high speed grinding of the walls of the turbo. Taking out the intake tube and a few picks or vid while the car on to see if it has any shaft play

Probably not bad just rubbing somewhere. Or the turbo is resting on the block too much (not enough clearance) and what you hear is resonance. Could actually be a ton of things.

Hopefully not a failure....[emoji852]

Is cleared by a mile from the block, i make sure of it. My money is on the bov slight leaking. Tomorrow will post about it if the shaft went to heaven

Now that I listed to it with headphones it definetly sounds like a leak or seals rattling. Probably the seals in the bov or it not being tightened down. Sounds like air escaping out of something.

Yep, that is what i am thinking also. Can you post a video of yours to give me a comparison? Thanks

There is a video of an s280 with a 2j in the fiesta nation Facebook group I'm not able to and probably won't be able to tonight.
