Well, I blew my motor this moring and it's hurting bad. A rod went straight into the side walls of the oil pan. So hopefully my short block is okay and all I need is pistons/rods/oil pan.

I am going to purchase some Wiseco pistons (8.8: 1 compression which are 0.02 bored) for sure but was wondering if Eagle rods H beams were good enough so this wont happen again.

This was on an AT 05 g35c with only 22XXX . I had a vortech blower pushing around 430hp/350tq (blew in 3rd gear).

My question is how much hp can the eagle H beam rods take if my goal for the built is around 450- 475hp?

 

Sorry to hear about your G bro. Your G was one of the cars that helped inspire my build. I hope everything works out well for you. Keep us posted.

 

holy ****, catastrophic failure on a Vortech, I think you are the first.

 

Domestics use eagle H beam rods for over 1000whp, so yes they are fine.

 

H beams are good to about 550-600 WHP in the VQ, You should be fine.

 

I'm intalling Eagle's with Arias HD (best pistons out there, thanks Sharif) right now, I have the same question about it a few month ago and with all the info that I found I can tell you, go for it

P.S. There some members with Eagle's and 700+ whp...

 

The manufacturer rated spec is 1500 hp for the VQ. I posted a scan of their data sheet somewhere on this site some time back...

 

thanks for the help guys. I'm soo shocked at the moment that it blew bc for one its an AUTO and a vortech.

It's at the shop right now getting teared down for the rebuilt but my question to u guys out there is do u think my short block is still okay?? The piece of the rod went through the side of the oil pan and not the block so can I get away with just reusing my shortblock and building the internals?

 

Depends... in my opinion, I wait and see if the block is OK, a good maching shop can tell you if there some damage on it... btw I first found what happeng there because is seems to me that there is something wrong with the mix or another thing because with your whp and miles on the odo is not normal to break the rods that way...

 

Where are you getting this information? The eagle rods will laugh at 550-600rear.

 

^ he got that information as he is a sponsor and has higher priced rods to sell. Domestics use them all time for crank and rods, and make 1000whp+ on small block v8s.

 

Yeah I know, I just wanted to hear his explination. My friends have supras doing 800+rear on eagle rods.

 

I'd be more concerned about those pistons than the rods. The eagle rods are good for well more than those pistons/ringlands are capable of...

 

eagle makes a great rod, and it is light, too. the wisecos shouls be fine for your build, too....

 

That is WAY too conservative. Eagle rods are about the best bang for the buck engine component available for the VQ.

To my knowledge, I was the first one to run eagles in the VQ. I just did a tear down due to a headgasket issue to find a broken piston and a bad crank, but the eagles mag'd out just fine.

Engine builder I took them too said eagles are the ****. Asked him about the eagle's strength in relation to pauter rods and he laughed and said I would have been foolish to buy pauters. At half the price of pauters, eagle rods definitely are the ****

 

Even more bad news. They took the motor out and took off the head and block and found that my shortblock is gone. Worst part, is that it damaged 7 valves and took out my upper oil pan.

It will be going to the machine shop tomorrow to see how much the damage is on the head.

If my stock valves are bent, is there any aftermarket ones that are around the same cost as stock ones to replace? I will be running stock cams bc I dont want any check engine lite to pop up.

 

try and find a 2nd hand longblock. save machine time and money.

as for your power, no matter the combination, 400+hp isnt safe on a stock VQ. its all borrowed time

 

There are many who will disagree with you.

I can't believe this happened to you though Pharmd. Any indication on what caused it? Did you have gauges?

 

Rod failure is very rarely caused by anything other then running parts out of engineering spec. U can have other symptoms, like spun bearings etc, but most of the time you will find that the root cause is the rod distorting. I know there are many who disagree with me, i dont really care. Proof is in the pudding.

edit;

As for the topic at hand, eagles are a fine rod. I have never actually heard of an engine failure directly attributed to a eagle rod. They all come fully balanced and machined well. My last set of eagles were the only part of the engine to survivie 3 rebuilds, including 8 cracked pistons.

 

+1!!

I am very curious to hear what caused this. This sounds like some major damage. I feel for you bro. Who is going to be building your new engine?
