Be nice.

 

That "IS" me being nice..lol

 

It's far easier to crack an aluminum ring land, than to bend or stretch a 4340forged steel rod. I am not disputing you. I use Pauter and GTM rods in nearly all the buildups. But for a 500whp setup, Eagle is PLENTY. The 300zx crowd has been using Eagle in 700-800whp for many many years.

Not every customer is interested in pushing 600whp+ with their cars. And 500whp is nowhere near the limit of an Eagle rod.

 

Are you kidding me??? Who said anything about cutting corners, Julian..that is pretty insulting.

We choose parts (as there are many choices) after careful and thorough consultation with our customers...the people that pay our bills!

 

And?
In a perfect world with a controlled fast burn of intake charge, bugger all timing is the perfect situation.. full presuure buildup with no knock, straight down against the crank leverage.
Of course you're pulling timing.. you can have 45deg in the mid range in off boost and 15 deg at full load.. thats a heap of timign pulled.
Whats the big deal?
The lack of decent dynos in the US and an inability to dead head load the engine may be a reason that you are 'detonating the **** out of your built motor' but we can take std Nissan and Honda engines and have them run 10-15psi boost at 9.5-10.5:1 compression and not have any issues.

And someone should listen to you when you can't even spell the brand your are trying to push on people??? CARRILLO
FYI I've never seen a CORRECTLY fitted, sized and not overreved Eagle fail at 150hp per rod at the wheels.
I have seen Eagle, Carrillo, Arrow, HKS, Tomei rods fail from overreving, incorrect sizing and oil film failure @ 100hp/rod.

Eagle don't know how to rate their own product either.
They use the same rod in a 4cyl as a 8 cyl.
4cyl is 550hp set (137hp ea)
8cyl is 650hp set (81he ea)
SAME rod, 30% more revs pulled in the 4cyl and greater cylinder loads.. you do the math...

 

You seem angry ... when you are so defensive in your posts, and aggressive towards others...ultimately this just makes you look bad...let's have an intelligent conversation without the attitude...remember "disrespectful members will be banned"

-TODD

 

Is that "In House" GT Motorsports Southern California or Par Engineering Sydney Australia ?

 

our facility in Australia is stricly devoted for manufacturing ,nothing more or less .on the other hand our facility on southern California is devoted for performing the finale mashing of the components that we manufacture then installing these components on our test engines then dyno testing before it get distributed to our network of distributors and end users . things have been working out very well with this set up .I had noticed that you live in Australia .if you would like .pm me and I can arrange a tour for you in our facility in Australia .and if you ever visit the states your more than welcome to visit us here in California .don't forget sema is around the corner

Seems like everyone is jumping all over me for some reason.I simply stated we dont feel confident in Eagle rods.period end of story.Personal choices.Im done debating with anyone on this isssue.

 

And what? We use a Load based Dyno Dynamics, same one used widely in Europe and Australia FYI. And when I was reffering to timind Im reffering to on boost full load timing. Example: the ECU wants to run 23 degrees, we will say run 13 or 14 degrees at that load point.


Thank you for the spelling lesson, I never claimed to be a perfect speller ot typist...
And I have seen stock rods to top fuel rods fail for the same reasons what on earth is your point??
Is this ricer math?

 

Not meant as an insult, what I meant was if your already spending the money on an engine build, what is a few hundred more for a real beefy set of rods? You and I both know the profit margin on a set of Pauters and a set of Eagles is the same.The failure potential for the rods would be the same under certain conditions:detonation,oil starvation,incorrect installation/sizing,over revving,ect...
However, the failure rate under normal conditions are greater for the weaker rod than that of the stronger rod, so my question to you and the point I am trying to make is this.
Do you feel comfortable running an economy rod over a top quality rod? (Economy was the term I was given by an Eagle rod distibuter themselves,I did not make it up.)

 

Dyno Dynamics: A machine that have demonstrated will read 18% different between gears and with the their sales rep standing there babbling like a drunk idiot trying to explain to no avail.
Its a simple calculation of toque and rpm, something that it fails to do accurately.

The ECU only wants to run as much timing as YOU tell it.
13-14deg advance at full load is what should be expected on short stroke big bore engine... whats your point?

Point is that installed, machined etc correctly Eagles will and do, exceed any limitation you perceive them as having.
You wouldn't put Eagles in a 600hp engine, but RB26 std rods will stand up to 600hp at the wheels every day and have nowhere near the same spur or gut strength let alone beam design of a Eagle.
Perhaps you should do more engine work and experience these things instead of reading about it and making off the cuff comments.

As mentioned by someone before, you seem to be on the defensive.. somehting to hide or just tightly strung??

 

Im finished debating with you..I am entitled to my professional opinion as are you..It is obvious this debate will go nowhere..You have resorted to bashjing not only my knowledge but the equipment we use when you probably dont even own a dyno.What is your background? I am curious to see what you know with your 30 something posts here on the 350Z board.

 

It sounds like everyone else is on the defense due to MRC's personal opinion. I happen to agree with his theory as well. Do it right the first time and end it..a few hundred bucks shouldn't stop you in a such a complex process when you are already putting in top notch components....

 

I,m not taking sides here but what I think MRC means is what the stock 350Z ECU is doing.

When using the Utec for tuning & opperating the Z the software allows you to see what the OE Ecu would be doing with regards to timing & fuel in real time.

 

Exactly what I was reffering to, thanks, I assume Spanners with his almighty knowledge knew what I was reffering to, but obviously he does not.

 

Until I see a built engine fail due to an Eagle rod, I see no reason not to use them if you're just looking for 500ish whp.

 

Back on topic, the issue was a failed JE piston that was obviously a design or material flaw. It really sucks to have to rip apart the motor to see that...

 

Bashing equipment.. indeed.. I seem to recall it all stemming from an uneducated comment based on Eagle rods made by yourself, and hp claims on a machine with very obvious flaws, 'fudge factors' employed and alot of "tugging of the ol' saus' "
In my professional opinion, I wouldn't run a Dynamics machine if it was gifted to us.
The setup we take possession of in the next few months 2nd hand is US$120k and have been using that same machine now for 3+ years.
Same hp every pull, every gear.. dead head can see hazard light current draw as the lights flash on and off.
No variables for wheel spin, rack down, weight.
I've been building and tuning performance engines in my own business for 6years.
Motors built for customers all over the country and world.
Typically 10-20 Turbo Nissans in my workshop at all times, 3-5 fully forged engines built per month and approx 15-25hr week on the dyno.
Never an engine failure nor a tuning failure.
The fact I don't spend 1/2 my life on here and have hundreds of posts a month, means maybe I have something better to do.
