do u have any pics?

I'm running manley rods and I dont want that happen to me

 

I havent seen one break at that power level but then again anything can break at a certain point?What you need to worry about is why it broke?Bad tuning .bad installation or whether or not it was just a bad rod?Post up some pics and you will get a better answer to why it broke

 

send the pics to someone and have them post em

 

show the pics to Erl performance and they are still trying to figure it out i have to send them moe pics..... all the other bearing look like new and it was tuned by a good tunner
.... oil pressure was good...if you want pictures email me at Civictruck88@aol.com

ill say it broke from a bad install......or probably might have gotten a bad rod....who knows

 

How many miles are on the motor?

 

have they recently changed the amount of ethonal in the fuel in florida? that could possibly throw off the tune.

 

it was on c16.... and the rods only had about 1000 miles

 

Here are pics

 

what fuel did you use? maybe you got bad fuel?

With Mase as the tuner.. thats a given that a bad tune has been ruled out as the problem, lol.

 

What does your rod journal on your crank look like? What do the bearings from that rod look like?

We've built and tuned at least 50 or more customers engines with Manley rods without a single issue. We've also had great success with the lightweight all motor rods in N/A applications.

 

were these the "turbo" Manleys? i know they have 2 different ones..also Im no expert but that looks like a cap may have come loose and the peice that broke off the rod came from the crank smacking against it at high RPM?..?

 

they all look new..... no scares........

 

Looks like "spun rod bearing gone wild" to me, but I'm no expert..

Who built the motor?

Check and see what the rod and mainly the main bearing clearances were, you had alot of heat around the big end of that rod...

 

the rod still has a bolt screwed in it and the other side is broken off..... these were the turbo tuff manley rods..... who nows maybe it was just my luck....s**t happens

 

Looks to me like a bearing failed and the rod let go

 

they were oem honda bearins

 

Do you have any pics of the crank and the actual rod bearings from that journal?

 

i guess i found a way to break them,,, not sure how though

 

Andrea is asking the right question. Sometimes you can freeze a bearing to the crank so tightly that it actually breaks the rod because it can no longer spin with the crank. That would be much more of a builder's fault than a rod fault. The spinning crank just snaps the rod in the weakest spot. Let's not be quick to blame Manley or yourself on this.

 

Who built the motor?

 

what time frame would something like this happen at

FRANCO TECH!!!!!!

 

Looks like a lot of discoloration on the big end. Can you get more pictures of the crank and rod bearings? Is this the black coupe that Shawn drove at Bradenton? If it was Dan said the datalog showed 10,200RPM.
