Volvo K24 turbo in audi application.

[Rocco]

so then,why the bearing failed??

did you heard some extrange metallic noise from the engine before the fail?

Because the guys who rebuilt my engine probably re-used the rod bolts and did not measure it over.
Just a theory.

Log on the last run, when oil pressure went, with very low timing:

Sounds like you should have put the k24 on instead.

Would have happened sooner or later anyway...
This is no way the limitation of the stock engine, bad mapping or knock.

[Error404]

bearings spin because of insufficient crush so you need to get your big end bores or mains resized

[andy10v]

that is quite steep, i paid $50 shipped for the one on the turbo that dimtri showed.

Can you remember who the courier was?

[andy10v]

Tired?
I had all rings, all bearings etc changed a year ago...
No, my engine was not tired.

Will take off the pan, cut the filter and see wtf...

That is sad to hear, hope you get a relatively straightforward fix.

What is the plan for the engine then? Or will you decide when you get it apart?

First pull apart and see how much damage is done.
Probably "new" crank, new shells, and I have a set of H-Rods that'll get put in...
This is if the block is OK.

[Ross]

That sucks, sorry to hear that... just be glad you didn't put a rod through the block

Still, looks like it's making you peak boost around 3900, not bad for an old-skool 420hp turbo?

It's not bad at all. Pull is in 3rd gear

[Thuppu]

...and I have a set of H-Rods that'll get put in...

So this was a good thing after all. The rods don't need to collect dust on the shelf anymore.

What kind of noise did the engine keep? Do it still run, or is it jammed?

[prj]

It's big end bearing knock and oil pressure is gone.
I did not run it like that for more than 10 seconds.

It's of course running, so I don't think the block is gone.
Will see when we open it this weekend.

1.55bar to near enough 7k rpm as well :mischeif:

What injectors are those for 78% duty at that power level?

[Billman]

@Prj
do you have a log of a big turbo engine you mapped? Log from the final map.
How log do you need on the dyno to map an engine?

510cc ev14, I have stock head, stock ic on this car.

Bad luck Dmitri but it does seem like re-used bolts contributed to this failure - thats my opinion from long distance without seeing anything of course.

@Ross - these are same injectors that shipped to Sonic, and will come to me for some playtime - Dmitri proved the latency numbers to be close to theory on his car. I will take a second set of measurements for comparison. It looks like these are good to go for you and others as you can see from the IDC on hefty power levels for K26/27 sized installations. This must be in 430-450bhp territory.
