blocks pulled apart and what i have found today tells me that it is possible...
will upload pics when i get home. Just installing new h beam rods found cylinder 1 and cylinder 4 rods where slightly bent... hmm... any thoughts?

detonation.

Yeah.  High mile ones are known to bend at standard power, let alone a mapped one.

Its called the rod lottery, you might get lucky, you might not.

If its bad enough, it'll hit the squirter too.  That said, I'm running NLS and AL and mine gets death on a daily basis.  128k so far, and it seems reet.

So yeah, very possible.

Not bad but def bent old and new rods... just picked up a gonzo gttx turb and 630cc injectors for $600 so I figured before I destroyed my block I should throw some rods in her can't wait to get back together with new lsd too... and that was with 221,000mi

Was there any signs that the rods were bent, knock or rattling? Out of interest what's the part no on the bent ones, what engine did they come out of?

Honestly I couldn't tell cam chain was a little noise that was the main reason for the over haul... one thing led to another pulled apart to find to my surprise. Its a 2002 awp engine code factory 180 hp... rods are in the scrap heap next time im up there ill take a look at the #

uh ohhh, thats my engine code and I'm running a k04-023 on a 200000+ mile long block. Guess I should invest in some connecting rods. At least the stock ones bend instead of break..

Can you post a pic of the rod bearings?

not at the moment but Ill take a pic tomorrow when i get back up there.

Peak cylinder pressures will bend a rod.  they will go if you spike silly boost on a k03s.

It was quite high... was using forge waste gate... was going for 250 wheel...
... was happy with dyno... didn't last long... I'm just glad I decided to pull it apart when I did... was stupid bought a co2 cooler for my frontmount to get more from the excessively high temp stupidly high boost (poor turbo and reason for new turbo) thanks to the waste gate and I'm sure it wasn't set right

what was the best dyno run?

No need to run a k03s over 21psi tbh.  Anything else and they just turn into a heat blower and have no effect on power.

This. And... detonation.

were you using the hard LC/NLS at all?

you FWD? If so, what are your LC/NLS settings?

What make you so sure? You  have not seen any logs of what im running (even tho the first time you mentioned it I sent you a pm asking you nicely if you had the chance to look over my file) and got no response...  So what your telling me is that antilag launch control and or high torque would have absolutely nothing to do with it?

You don't understand how many PM's we get. It's nothing personal.

As for the detonation comment, he's likely correct. Cylinder pressure is what bends rods. Detonation causes a lot of abnormal forces. That's not to say antilag didn't have anything to do with it, but don't discount what he's saying.

yes launch is 2800, speed threshold 19kph, ftomn 0.0, rmp cut threshold 4250, ignition cut duration 300ms

cool thanks

I'm not sure. Just sayin it is a possibility, since if you are within the k03's compressor map, you most likely won't bend rods unless something else is causing high cylinder pressures


So post them.


See my sig re PMs. Also I don't typically have time to dig around in .bin files... there is no way of knowing what is goign on there w/o looking at each and every map. Generally logs are more useful since you can gather a lot more from that than digging through somebody's bin in a given amount of time.


Could be. No idea.

... stuck my foot in my mouth on that one... Sorry I didnt see your sig  :-[

I have seen plenty of broken AWP style rods from high boost K03 setups. The turbo can make plenty of torque for a very short range.

Every 4-5 months somebody is patching up a block with a hole in it from that. Always the guys with water / meth, spiking huge and clamping the w/g nearly 100% at all RPM.

Those stock 19mm rods are not strong whatsoever.
