I don't think mine is blown but I'm not a Turbo expert. It had a bad boost leak and looked like the wastegate loosened up. That was probably why I was getting surge in the mid range. It was still making plenty of boost when i took it off...

Lars i think 29psi is way too much for this turbo and that probably killed it. Just curious, what was your maf lb/min @ 29psi?

I dont see why 29psi was to much it was still not flowing 49lbs on 29 from what i remember.
I wanted to crank it over 30 if possible just never got there.


Now keep in mind people my post does say ZFR and thats technically wrong. I called it a ZFR cause it was converted to be that.

THis is technically the first EFR out then eventually converted.

Its a great turbo but at 29psi it did not give me what i want or scare me one bit. Maybe i have issues not sure.

ANd yes the compressor wheel is pretty much stuck hard to turn with massive amount of up and down play in it.

@29 psi I was at 47lbs/min on 100 octane with my ZFR. Same thing happened to mine man, exact same way. The thump or pop and no more boost. So sad to see that turbo go, I loved her.

I was seeing around 48-49 maf/lb min on 26psi 93oct. Both of your numbers seem weak for 100oct/e85. I wonder if its the zfr mani?

Edit: I mean stock mani/ zfr housing.

From what i have heard the people that send them in get nothing done. THey offer them a rebuilt one for 1300 ish. THere are no rebuild kits for these either.

There was a second revision put out. Like i stated before i got this EFR the first two weeks they were released and then later had the ZZP exhaust housing done.

It is what is is.
