I received a shipment today to begin building a few motors... I snapped some pictures of the eagle rods vs the Pauter rods..I would feel comfortable running the Eagles making 600wheel horsepower!...These are definateky a very beefy design.

Enjoy!

 

Don't forget about the weight difference

Pauter = 630-640 Grams

Eagle = 550 Grams

 

It looks, and seems to me that the Pauter rods might be stronger.

 

It's nice to see the Eagle rods gaining some traction in the VQ community. When we finally have ppl making 600+whp with the Eagles, then the whole issue regarding their strength and reliability will finally be answered, especially for those in doubt.

 

so the beefier but LIGHTER eagle rods would be an obvious choice?

 

nvm...just looked through the pics again and realized the the Egales are solid all the way, so yeah def would restate the the egales will prolly hold more.....but im no pro,nor do i have any experince in motor Tech

 

What i have heard is that pauter or crower rods were the badboys for big hp motors

 

They pretty much are, however there is a dispute whether or not eagles can handle powers up to 600whp. Some dispute that they'd rather go with the pauters for its tried and true design as well as many Z owners that are in 500 and up horsepower range have yet to bend one of the pauters. Yet, some cannot justify to pay that much for pauters where the eagles are more economical. From what i have seen, no vg owner has even tried to push limits on the eagle rods and because of that there is no real definitive truth on how much power they can hold.

 

Eagles look nice but i remember all the rod bolt failure problems back when i used to mod Hondas.

I'd go Pauter anyday.

 

The bottom line is that they are more expensive up front. But IMHO it makes more sense to spen more up front and not worry about bending or breaking one. If you are building your engine, you may as well do it all right the first time as rebuilding it if something blows is A LOT more costly. Do it right the first time and save a TON of money.

 

I agree if the power goals are over 550-600 hp...the fact of the matter is, there are not enough motors out there with eagle rods to PROVE what power they can or can not handle, this is ALL speculation...

i would feel comfortable running 600 wheel hp on the eagles...when i build myself a darton sleeved motor, and run 23-25psi, i'll use pauters, until the research is more conclusive

 

Im building a new shop on my property after losing my lease of 10 yrs on my old one. One of my first prioritys is to build the motor in my 03 Z Vortech. The eagles are so much more reasonably priced. And u have to relize that with the bigger companys ur paying for overhead and their name. Im going to give the Eagles a chance to prove themselves to me on my build. Structurally both look sound --I would be curious as to The material used in both and u have also got to relize the weak link being the Bolts. Its interesting as far as the weight difference. Much more research on my part though before I start. This is new territory for me but Iv been building motors for almost 30 yrs and am excited bout creating a new life form which obviously has good Genes !!

 

Eagle uses 3/8" ARP2000 bolts in both the VQ and VG30 rods. I have personally used the Eagles in a VG30 making 850 Rwhp for 2 years now with no problems from rod failure

 

If I remember the rod bolt failure on Hondas was because they were not ARP bolts such as those used in the VQ rods.

 

Anybody who believes that EITHER of those rods are going to bend or break at ANY power level that you'd make on the street knows very little about engine internals. The only way you're going to snap one of those is with detonation, and by then it won't matter which one you have....

Either the pauters or the Eagles are overkill for anyone under 800whp....but overkill isn't a bad thing. I love some of the very "educated" comments in this thread about how the rods "look" coming from people with no experience building motors.

 

overkill is the best word to describe these two rods, but like you said, overkill is a good thing when building a motor that is going to see a lot of abuse
I put the pics up to visually give poeple a baseline comparison, it helps to SEE them side by side...but eagle has been making rods for years and the exact same design has been used in several, higher hp applications compared to the numbers that we are commonly pushing with the vq's

TODD

 

Put me in for a set of the lighter, cheaper, very proven rods

 

If I am not mistaken- also from an engineering standpoint based on stress distribution the H-design would be stronger anyways. Obviously other things play in to the strength such as material and processes. But I would think that would be a good reason why the h-design is so widely used by other companies. This does not mean that the Pauter lack structural integrity of course as they are well proven.

 

The Pauters are still way stronger than the eagles. You cann't compare forged to billet

 

I dont think anybody would deny that... but unless you are approching 900whp, you dont have to worry about either one.... as long as you arent detonating like briguymax said
