Re: Manley rod Breaks (96BlackPearl)
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

Re: Manley rod Breaks (Turbocivic94)
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.

Re: Manley rod Breaks (Turbocivic94)
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?..?

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...

Re: Manley rod Breaks (96BlackPearl)
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.

Re: Manley rod Breaks (96BlackPearl)
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.
