I am raising the factory redline to about 9000rpm to get the most out of my 280 cams, i was told eagle rods werent good at rpm levels higher than the factory redline.???

which rods are most people using and what is your new redline?



cheers

I haven't heard about any bad reviews about any forged rods for the 63 some are heavier thought which are marketed to hold more horse power but never hear of any forged one's faulting, maybe someone else has if so share the story.
 
Sorry Godfather, but whomever told you that is full of it :) You need only look at who has used Eagles in the past and who continues to use Eagles now to know that people like Rob Barac (used to) and Buschur (still uses them) dont know what the word 'stock redline' means :lol:

Matt from The Hitman in penrith told me personaly that he has seen them fail at higher rpm...

as far as i know eagle rods are awesome, but, i told him that i was going to use 280 degree cams and he told me not to get a set of eagles as they fail after 8500rpm...????
 
i found these http://www.extremepsi.com/store/customer/product.php?productid=18352&cat=458&page=1
but after what Hitman said and also another post in here which says to stay away from Wiseco pistons im having 2nd thoughts.

Rob, I've got a 1mm (copper, doesn't compress) headgasket .. and the deck height isn't standard either.

I don't have any direct experience with the CPs, but I'd avoid wisecos if I were you - we were very careful with the tolerances on my motor, but they're still noisy as all fuck on startup.

can someone set things straight please, lol

Most of the time I don't think its the parts that fail, its the engine builder/machinist who fails.
 
The first time i ever heard anything bad about Wiseco Pistons was here. And the user claimed they had a loud slapping noise (which can be expected from forged pistons before warmed up), however i know people with Wiseco pistons installed and you could barely tell theres forgies in there.
As for the eagle rods:

Eagle "ESP" H-Beam Rods
Mitsubishi

"ESP" connecting rods are forged form 4340 steel and utilize 3/8� ARP 2000 cap screw-style bolts with alignment sleeves for a perfect fit. Packaged in weight-matched sets (+/- 1g). Sizing is done on the state of the art Sunnen Krossgrinding system. "ESP" connecting rods are the perfect choice for engines up to 900 HP.


-Same ones i'm using.
 
Rob Barac used to run Eagles during one stage in his engine development, and Buschur still uses them on a lot of customer cars.

Liberoz is right, I dont think I've ever come across reading about one failing from a manufacturing defect or not handling the power, moreso from tuning when the cause is from running lean or knock.

Do some homework and you'll read time and time again about 600-700whp DSM's running Eagles :) Buschur himself said that 9,000rpm would be the safer limit even though one drag car ove rthere has run 10,000rpm with them :twisted:

When you see a lot of 4G63 owners running them without problems and endorsing them like this you kind of wonder why anyone contemplating a high powered street car would use anything else: "I've been running the same Eagle set of rods for 3 years making between 600-700whp, 50-100 dyno pulls, and passes in the high 130mph to low 140mph range. I have absolutely no complaints about them. The Crowers may technically be a stronger rod but they're also a good bit heavier. Until I see a reason, I have no desire to switch to something different."

Matt and the guys at Hitman are top quality tuners and one of the best there are around. Sometimes a tuner can make a mistake and blame engine failure on an engine part (aint that a fact) :lol: . Did you ask what make of engine they were experiencing Eagle failures on? were they 4G63's? did they build the engines?

i dont remember if Matt said 4g63's, all i remember is he said not to get eagle rods cause they are shit with higher rpm, he said they stretch etc etc and they wont take more than around 8-8800rpm
 
The context in which he said it is important. If they are experiencing problems with Eagles on other motors then its an entirely different thing as different engines experience different kinds of loads on rods per rpm. ie smaller capacity engines with small strokes would handle 9000rpm better than say a larger capacity engine with larger stroke at 9000rpm. Even on an identical engine if it were the same bore but different strokes, the engine with the longer stroke would have more load placed on the rods.

yes of course...

i will call him again and ask what motors he heard of that were throwing eagle rods.
 
they are custom with over 300 duration :wink:
the rods are the way to go, dont let anyone tell you they dont work.
 
I thought you replaced the Eagles when you went the bigger motor Rob? If you still have them then thats testiment to how good they are because you certainly gave them a good workout :lol:
 
the only thing i have heard about eagles is that you have to check for out of round as they may require some machining before use. this is the reason i got SCAT rods instead. nothing to do with direct load capacity though.
