The force applied the shear the rod wouldn't simulate actual stress on the rod in an internal combustion engine.

 

Like I said I'm not a ME, I'm just saying they could tell us which was a stronger rod and have scientific evidence to back it up. And could design some tests to simulate duty stresses.

 

Can you please show me where in my previous post, that I stated a Pauter was a forged rod!

You guys are misinterpreting what I am saying here. NO where did I say that Eagle was a bad rod, hell I purchased them for my built block. I did this becuase I am on a budget and didn't feel the need to go past 6-700rwhp.

What if you did make 650rwhp at the wheel! Would you what to spend your time worrying everytime you boosted, knowing that your rods are rated at 750rwhp.

 

out of curiosity, where did you find the 750rwhp rating? please share

Thanks
TODD

 

I have also never heard of this 750hp(whp?) rating, Ill call Allen on Monday to see what your talking about.

 

One question men :

I was always told that h beam rods were made to sustain high spin and abeam were made to sustain high torque like high boost .

Why they aren't super strong a beam (or i beam) rods designed for boosted vehicles, we see always h beam?

 

Carrilo has come out with a Super A billet beam which I am using on my build, talking to Race Engineering and Carrillo they feel comfortable that it will handle 900+ it is not as cheap as an Eagle but a lot cheaper than a Carrillo H beam and I think about the same as the Pauter which is not an H but rather a design they call X beam.

I still say Billet is stronger then Forged.

 

Performance Nissan has the the highest HP VQ right now i think, that everyone knows about (1600 i think) and to my knowledge they use carrilo's.

 

Turismo, I want to make sure the information presented here is accurate. Race Engineering is a retailer. I spoke to Don Pauter himself, at Pauter Machine last week, and he told me they are forged, and explained the process in detail for me. Oftentimes, the confusion stems from people using the work billet and forged interchangeably, or even worse....the word billet forged, which is a misnomer. Even Pauter's literature is a unclear.

Pauter and Eagle rods are both FORGED, and then all rods are CNC machined finished. But the struture of the rod is forged.

In regards to reving past 7000rpm, with proper cams, intake manifold, FI systems, people will be making power well past 7000rpm in the future. Some are doing it now!

 

Forged steel is stronger than billet steel. This is a basic engineering fact. Talk to Eagle, Pauter, or Carillo, and they will tell you the same thing. And all of their product is forged as well...even the venerable Carillo H-Beam.

Billet rods are often used in custom applications, when a proper sized forging is not available. Also, Ti can't be readily forged, so they cut them out of billet.

 

The post was on the first page....but that's not the point. The point is they are BOTH forged rods. Futhermore, hp strength "ratings" mean nothing. HP won't break rods, CYLINDER PRESSURE or REVS will. So again, where did you get your magical 750rwhp number?

The next step up from cast iron is the forged steel crank made from either 1038 alloy steel or 1053 alloy steel. The 1038 steel is very basic and contains just enough carbon for heat-treating and a little extra durability. A forged alloy steel crank is very durable but it too has its limits. The strongest crank with the best material is a 4340 billet steel crank, but it is not inexpensive. These cranks are primarily used on high-end racing applications.

Basically he is saying, depending on what type of material is used, billet is stronger than forged.

 

This is confusing people..and I want to avoid misinformation on the boards. Please dont take it the wrong way. If you take two identical steels, lets say 4340 for instance...since this is the primary material used in high performance rods. In this case, forging is stronger than billet CNC...no question about that.

The guy writing the article merely points out that you CAN make something stronger in billet CNC form, by choosing a stronger material. Hence, Ti rods are billet, and they are stronger than a forged steel rod. The process doesnt make the rod stronger...the material does.

 

The great thing about the VQ35 crank, is that its already made from 4340 chromoly forged steel. The race teams usually start snapping them at 1300whp!

aaaaa!!! 1300whp!! wow !!

be proud of ur crank VQ35 guyz

 

so what vq we got out there using pauter rods getting 1500hp?
you dont want to take eagle rods on differant engines to use as a gauge of strength so dont talk about x engine using pauters making 1500+ hp.

and if you do want to use other manufactures engines into play with puater/eagle.
well eagles 4340 rods are in my sbc 434 ci stroker now . 670 rwhp and a 400 shot on top of it.

that would be 1150+ rwhp on an eagle rod rated at 750 suposed hp

and then there is my buddy making almost 1700 on his motor/nitrous combo in his nova using the same eagle 4340 rods



pauter makes an excellent rod. so does eagle (and in my opinion better , they are lighter and just as strong)

 

2 things worth note here:
1. When did a 400shot every make 400whp........

2. You're talking about a 8 cylinder engine there Socrates.

 

Nitrous shots are typically rated at WHEEL hp...not crank hp...

 

thank you
