Volvo K24 turbo in audi application.

What ECU was he running?

[prj]

Vems.

hmmmm

@Ruffiano
do you like to share your config file?

[Billman]

It seems that this happened due to very lean conditions. The timing map looks ultra safe.

tough mate,

check the map before making any assumptions about ECU Dmitri...

who mapped it then? what a bad luck..

Not making any assumptions about ecu. Ecu is just a calculator, I did not blame ecu for this.
I just said engine went boom due to knock or alternatively there was a mechanical fault due to possibly mistakes made in the engine build.
Stuff like that does not happen at 600nm with stock rods with everything running correctly, as I have been able to prove many times. This turbo is less powerful than even a rs2 turbo. How often do you see such engine failure on chipped rs2s?

[A80Avant]

knock control feedback is not all you need assuming that there wasnt a mechanical fault.

if this was down to knock, it could have still been avoided if the map was properly done. (ie so that there no knock in the first place)

[prj]

Again, I did not blame this on purely knock control.

Here is my original post:

That's not rods, that's knock.
Exactly what happens when you have no knock feedback at all and run too much timing/boost.

At no stage did I say "VEMS blew up the engine". Don't read into things too much
Possibly because it happened when cold, the map was not correct for cold conditions, and caused an excessive leaning of the fuel mixture for example... or injectors ran out, or whatever.
A million different reasons.

My point was to say, that 600nm does not cause a hole in the block.
I have seen holes in blocks with stock turbo also plenty of times now, but it is not because of some imaginary torque number.

[A80Avant]

sure, but i know you a little more than you think, and you have to admit that you did leave your hint there.

[Jamo]

Where's the map link out of interest? Dunno about this argument going on here it failed its getting rebuilt end of IMO
Only way to know what happened is to take it apart and analyse
Couldn't give a hoot what ecu it was

[prj]

I did not, and I have nothing to admit.
I said uncontrolled knock likely happened in combustion chamber, which likely was out of spec for the given connecting rods, and that you are not supposed to get holes in the block just because you are running 600nm on the stock connecting rods.

You are really reading into it too much. I have seen plenty of these engine's go boom on plenty of different ECU's.

Anyway, new block -> H-rods -> detcans on ears when driving for some time.
If this was not caused due to mechanical errors, then the knock that caused it with H-rods fitted will be enough to destroy the bearings. The weakest part always lets go.

how many rs2 turbos are making 360 ftlbs of torque at the wheels? which is right around 450ctq?

610nm a few I would say if they are running 1.9 bar chips

if anyone is interested.
