i simply can't get over the skepticism on this board of the eagles. they've been proven on nearly every other platform......what makes the way the VQ work so different from any other motor fundamentally?

They'll hold the power that almost anyone on this board is making, I'd be willing to bet.

 

I'll never see anywhere close to 600, so it looks like eagle being lighter and cheaper wins for me

 

Do you know what billet means?

 

Definition:

bil·let (plural bil·lets)


noun
Definitions:

1. chunk of wood: a short thick piece of wood, especially firewood

2. metallurgy metal bar in semifinished state: a metal bar or block with a simple shape that requires further working

3. architecture part of decorative molding: one of a series of short, evenly spaced blocks or cylinders forming part of a decorative molding



All billet means is that its a solid metal. has nothing to do with how strong it is.

 

I agree. I did some reading on forged vs billet crankshafts and there was no definitive answer on which was stronger. The main advantage of billet parts is that it allows for custom fabrication since it is CNC machined from a block of metal. This is great for a performance shop where custom one-off applications are required. On the other hand, forged parts require an expensive die for every application which restricts you to the most popular forgings.

 

Yes it does, due to the manufacturing process the parts made from a billet keep the original grain structure of the original piece and will be stronger.

 

This is EXACTLY what I was talking about in my first post. People posting about something based on NO FACTS. Probably just what they "heard" from somebody.

 

Please show me 1 application where Eagle has made over 1200rwhp. Why do you think they rated it at 750hp. Pauter rods have been known to handle over 1500rwhp without a problem.

 

show me a Z making 1200whp

 

Good debate. I too would have no reservations about using Eagle rods in high whp applications, and I am sure its only a matter of time before people start pushing really big power through Eagle built VQ35's. 500 grams of weight savings on that crank is ENORMOUS when spinning up these engines to 7000rpm+. There is always going to be a balancing act between saving weight, and maximizing strength. Rarely do forged rods snap on their own...they nearly always break from detonation, hammering the rod bearings, and eventually spinning, heating, and snapping the big end.

Pauter rods are the most used and tested, and builders have established a comfort level with them. IMHO, the more choices the better.

Like the "what is the best turbo kit" question....the best rod question will never be conclusively answered. Use what you and your engine builder are most comfortable with.

Oh, FYI....Pauter apparently has some misinformation on their job cards. Even though their cards and marketing material say billet (implying they are CNC machined from a solid block of metal...they are actually forged...just like the Eagle rods. And for the record, all things being equal, a forged rod is stronger than a billet rod, becuase with forging, the metal grain structure remains uninterrupted; ie...the gain structure will follow the curves around the big end...for maximum strength. Pauter does make Ti billet rods, but everything else is forged.

 

I was informed by race engineering that the Pauters are billet rods and the Eagles where forged rods. To me I would feel more comfortable with the Pauter rods in excess of 700hp. That is why Eagle themselves have rated there rods at 750whp. Pauters have been tested on numerous cars pushing well past the 1200rwhp without any problems.

I forgot what company has the 1900hp 350z, but I think they are using Pauter rods also.

I understand what you are saying Sharif about the weight savings past 7000rpm, but if your not making power past that rpm, what difference would it make? (not being critical, just asking a question)

 

Why do you keep talking about cars making 1000+whp? There isn't a turbo kit out there that is capable of producing that horsepower on the VQ. The vast majority of FI cars will be in the 400-600whp range. People considering Eagle rods are building street cars not race cars. Therefore, they don't need rods capable of 1000whp.

 

Anyone want to dontate a couple of each, send them to the Mechanical Engineering lab at my university and let them do some testing on it? They could probably give you some definate answers instead of this talking out of your *** crap.

 

where are the cars making over 1000whp??? When a car makes over 800whp then it MIGHT be better for them to go with something that guarantees higher HP numbers... but up to those points the lighter weight is going to be more beneficial... and both pauter and eagle are more than adequate strength-wise.

what company is making 1900whp on a VQ35???

 

DreamWorks

 

how would your lab test them?? I am just curious to the process, not trying to argue.

 

Oh, I forgot about them... dreamworks works Miracles

 

I'm not a ME, but they have a pretty extensive lab. I guess they could test the amount of force to shear each rod? Maybe some other tests for bending? Like I said I'm not a ME, I just play with the radioactive stuff.

 

oh, okay. I was just wondering if they could test them in the actual motions and stresspoints they would endure in actual use.

Radioactive stuff??

 

So first the Pauters were forged and the Eagles were billet, and now it's the other way around??? You can't even keep your assumptions straight and you expect us to believe your BS on anything else?

It's very clear that you don't know WTF you're talking about.
