Can someone show me results where a rod failure in a 996TT caused an engine to blow up? I've always heard how "weak" the rods are, yet every time I see a post about an engine god bad it's a result of detonation / lack of fuel / lack of a quality fuel. The rods look pretty beefy from what I've seen in comparison to other aftermarket and OEM products. I guess there's only 1 way to find out firsthand.
the pauter rods have totally different construction from the stock rods

i agree , knocking on the 700 awhp door on a stock motor , sooner or later you will hear the rods knocking through the heads.

Have you looked at the factory white paper detailing the 996tt rod construction and material used?
You may be surprised how similar it is to many aftermarket rods, including the ones you have in your car.
I will post the white paper if I can find it again.....
Also, what boost were you running when you feel your bent your rods? Do you have any pictures of the internals? Specifically piston tops and combustion chamber?

the reason for the bent rods in my car was cold weather(around 40F) 1.34 bar and 92 octane fuel
i do not have photos of the combustion chambers but here are a few others

Stock Injectors at the time ? What Tune at the time? Sure sounds like a recipe for detonation to me that may have led to additional stress on the stock rods.

Do you happen to have any pictures of the rod bearings or tops of the pistons?

Well after adding our bosch 044 inline fuel pump kit we decided to hit the dyno again. Running a little bit more boost we were able to achieve 670whp and 700wtq. We will continue to extract more power from this setup but for now we are out of injector (630cc's). Big thanks to Tony at EPL for his incredible tune. On a side note the spike around 125mph is from the dyno loosing the rpm signal. Run was done on ms109.
car set is:
k24/18's
EPL software tune
USP motorsports intercoolers
USP motorsports turbo inlets pipes 2.5"alum
630cc injectors W/ USP injectors spacers
USP motorsports 3'stainless race exhaust
USP motorsports 044 fuel pump kit

Keep in mind that a k16 car that is detonating repeatedly will have much higher cylinder pressure than then a k24/18g car at high boost with a tune that doesn't detonate.

no i hve not looked at the construction white papers... i have held both the stock rods and the pauter rods in my hands.. i have no clue as for the materials used. i do know that the stock rods are an h-beam construction and the pauter rods are a +-beam construction what this means is in the +-beam construction the thickest part of the rod rests on the center tangent of the upper and lower bearing surface... the stock h-beam construction the thickest part of the rod rest on the outer tangents of the rod bearing surface thus leaving the center thinner allowing the rod to bend and not snap off under extreme loads
the reason for the bent rods in my car was cold weather(around 40F) 1.34 bar and 92 octane fuel
i do not have photos of the combustion chambers but here are a few others
