Cooked KO4

[GTIjames]

Well my car is been put back to standard with jkm at the moment and they discovered this when looking at the turbo..







not too good and not sure on how much longer it could last like that, so its been replaced as I dont want the engine eating it and it costing more 
 
couldnt tell anything was up myself but i use to get a jingling sound on spool up when the car was cold, once warmed up it stopped, boost was still cracking 28psi and holding at 25psi despite the damaged turbines

anyhow not 100% sure on the cause but it will be looked at further but just a few photo's of caution to those maxing out their k04s

i take it the bolts loose as it looks like its been hitting the sides   but good on them for spotting it

what software are you running, 28psi is a lot, I'm sure on stg2+ mine is max out at 22-23psi

was just thinking the same

Ouch that looks expensive!!

It's difficult from the pictures to ascertain if the tips have been hitting the casing or if it has been caused by stressing of the blades.

I see something shiny on the outside

thats boost gauge figures so might be slightly out, not been logged since i had it back from my accident as lost interest..

but running stage 2 + but with a forge actuator which i think might be the culprit as it increased the boost, i was running b7t5f8

turbo is just over 40k miles and been mapped for about 30k miles part bluefin and past year recently revo stage 2+

not going to blame software etc, i like to use the boost and have had 40k miles using it pretty much constantly   been great fun  

[gazbutS3]

Yes, an uprated actuator, but doesn't the software still need to request the max boost?

[MAT ED30]

who set the bluefin up for u ? as it looks like its been like that for some time  and was the bluefin setup for the uprated actuator ?

[Hurdy]

I've logged mine with the Forge actuator and had over 27psi on VCDS logs. This was due to overboosting with the actuator rod set incorrectly on the wastegate and the car was only requesting 25.5psi. Once it was set correctly it still slightly overboosted at 26psi, but it was within 0.5psi and so was regarded as being within operating parameters. Maybe your actuator was set a little too tight to the flap opening and wasn't getting the flow right. Not the reason for the blade damage though, just the overboost.

You can't setup Bluefin and I believe James changed to Revo last year sometime.  

[MAT ED30]

but would the overboosting make the blades get even hotter and the weak point are the tips as they are so thin hence why they have just come off

i thought superchips could set it up for u for the mods u have as i am sure nath had his changed a few times

Not in the scheme of things like you can on Revo. I had maps changed but they were just tweaks. I think the most boost they run is about 21-22 PSI even on stage 3.

[GTIjames]

it was revo before the forge actuator  

i thought the actuator was a fitted a bit tight as I was logging and getting overboost when it was first fitted, so i reduced the boost via the sps switch and had plans to get it back in to be looked at but never got time as i was manic at work and then pranged it..

probably my own fault for not sorting it sooner  

anyhow my next car is not going to have a turbo and no after market mods
