New Eagle Rods for MZR DISI engines!

And there isn't anything beefed up rods are going to do under the same circumstances.
If something is going to go from too much power on a very solid tune, with nothing going wrong, just too much power, it'll like be in the form of lifting the head.

A little early in the day to start drinking man...

Forged rods will take a HELL of a lot more abuse and sustain more room for error than our factory rods.

If that were true there wouldn't be aftermarket internals lol

Every popped motor, regardless of what caused it to go, has resulted in a bent/broken rod because it's the weakest rotating part we have from the factory.

What are you trying to prove?

[Tokay444]

That our rods aren't as weak as you're making them out to be.
A beefed up rod will put up with a little more abuse, but it's not a safety net for a bad tune.
You're still gonna fuck your couch if you mess up your tune.

Nobody's debating the need and importance of a solid tune...

I'm just saying that rods are usually the first to let go in most situations and that upgraded rods offer the most "Insurance" benefits among any other internal part. (Crank, pistons, etc)

What everyone is trying to tell you is that no tune is ideal in all situations. The fuel will be different from tank to tank, the weather is always changing, and sometimes you get knock and you cant explain why.

If tunes could be made perfect, then yes you would probably be correct that the oem rod is plenty strong.

Btw, what's the story with cylinder #3? I don't remember seeing anything on the forum about that or a solution. can anyone point me to some info about this?

Reduced oiling due to the balance shaft assembly...

Flow imbalance with the stock intake manifold causing #3 to run lean...

Maybe a combination of both.

Cylinder #3 seems to bust its rod more often than any other cylinder.

I seem to recall people throw Cylinder Misfire codes for #3 more than any other, as well.

It was #4 for me and i can 100% assure you it isn't the balance shafts fault that the bearing spins. i will have to take some good pics of the rods to show you guys that when these rods bend the beam it causes the big end to pinch tighter. I was lucky that i caught it before the cap gave in and spun the bearing becuase i can show you how good these bearings looked for 104000km of use.

For me i am starting to think that this is a hydrolock issue caused by fuel system issues but i am still looking into this so i will leave it with this 1-3-4-2.

I blew #2 when my factory motor blew up and my KMD fuel pump internals were the cause they were failing during a WOT pull and the car sputtered a bit and went BOOM, while WOT

my rod came out the block and busted my Passenger axle bracket...... when i built new motor and went to install axles i could not get the bolts in and it was because the bracket was fucked.

When you guys says hydrolock, I relate that to when water gets into the motor and causes it to seize. That is your typical definition for that. When you guys are talking about bending rods, and or burning rod bearings causing rod knock/failure, I relate that to something else entirely. These rods caps do not have a tang on them for the bearings to sit, and or snap into if you will. What happens is when there is an excessive load on the motor and your get any type of movement, be it thrust from the crankshaft, or the rods starting to go out of round the bearings will basically come together around the journal and melt together. When that happens, more often than not you will burn that journal on the crank as well as block that oil passage. That can eventually lead to creating enough tension as the rod will no longer want to turn/rotate and start to bend and or break. For the most part, you would be able to hear that onset of rod knock, but depending on your driving style (music, exhaust, or just the fact you may not know the sound), you may not even hear it.

The COBB AP will be a great indicator if your timing is wack and your are detonating. It will be absolutely visible on a log file. Obviously another way to tell is if you do pull the motor out and disassemble it. Look at the under side of the piston as well as the wrist pin. If you have severe detonation, that wrist pin is going to be discolored from the heat. Now the oil squiters will be able to help with that somewhat, but it will be a tell tale sign of that. Usually you will see an area on the wrist pin that shows where the rod has essentially changed outside diameter from the heat.

I have done some individual cylinder testing with EGT/AFR. I have seen these motors run very similar to a Honda motor (they have the same firing order), and cylinder number 3 is the one to keep an eye on. COBB does have the individual cylinder trim for timing, but no fuel at this time. Hopefully they will be able to write code for that in the future.

How much do stock rods weigh BTW?

Stephan, waiting for a message from you)

[Tech/Sales@EM]

Yes been out of the office and will be out of town the next month. I will still have answers for you by tomorrow tho before I leave.
