The K1 stuff is a very good piece for the money. Some of the better " offshore" stuff, only second to Compstar in my opinion, but way, way better selection for the Mopar crowd. I was one of the very early users of their parts when they first came out. Dan ( DRAM) got involved shortly after as well. We have had very good luck with their products.

I use K1 stuff all the time. No negative issues so far. Last motor was 1000HP and it's running well at >7000 RPM.

I would ask Wild Bill.
He has gone through 4 rods now, I believe.
Pretty sure they are K-1..
So,,,, He could, and most likely would give you an honest overview of them. I'm sure they have figured out what happened by now, and whether the rods were the culprit.
It should be interesting..

The first ones spun a bearing I believe. The second just broke, if I remember the pictures..
I have no inside info here. Just waiting to hear as well. But I'm quite sure you can't predict a rod failure. Unless you have a crystal ball.. If you do can you loan it out?

his combo is a stroker i believe so the condition may be for that rod/stroke ratio.i doubt we will ever know unless someone else brakes some with that combo.if rod brke like that on my i sure would not get the same rod again.

Re: K-1 Technologies Conn Rods - 08/07/10 01:17 PM
I can assure you all of one thing. A H-beam style rod just doesnt break in half. Bills problems were clearly from something else.
Also, a spun rod bearing is not the fault of the rod. A spun bearing is either improper rod bearing clearances, poor lubrication, or an oiling problem or overstreched rod bolts ( which would almost always be an old set that are worn out). Lastly would be if there was an oblonged rod big end etc. IF the rod got hot enough, THEN it possibly break. You are talking about a total catastrophic set of conditions to break anyones ( assuming its a quality brand) H beam rod.I'll try and post some pics later of what some customers have brought me, when done wrong.
All I am saying, is I wouldnt be making this a K1 witch hunt based on what has happened to Bill. Those are other issues.
However, Wild Bill and "witch" anything might not be a good idea right about now !

Metalstorm,
You may in fact be correct.
After the fact,sometimes its just an educated guess, but this isnt Scotts first dance either. I would be willing to bet he has a very good idea what happened.
Just based on my experience/opinion and knowing his experience as well.

I used K-1 rods and crankshaft in the 427 inch small block. Nice stuff and didn't have any issues with either one. The crank needed to be turned down to balance it but I'd rather turn one than add Mallory.

I run the same rod/piston combo in my stroker and I have had it to 7000 more times than I would have liked but it's still going strong Well I hope I didn't jinx myself 
I think Bill's engine just had too many hands on it
You should be the only one touching that engine from start to finish IMO.
Anyways I love my K1's they were almost perfect out of the box,just a little honing on the pin end for a few of them.

I have to disagree here. There is nothing clear about any of Bills photos, except broken parts. I don't see heat in the rod, but it is broken. Parts DO fail.. And those were the 2 new rods.
Not a witch hunt here. I have a K1 crank in my 950+ hp B1, and it is running great. But I have GRP aluminum rods.

by looking at the pictures, i'd suspect either the wrist pin seized or the rings butted together, pulling the rod in two. once cooled back down the rings might be free again, making it easier to overlook that as the problem. a seized wrist can do almost the same thing, although galling will be very evident upon inspection. in my experience, the connecting rod itself is almost never at fault in that type of failure.

Re: K-1 Technologies Conn Rods - 08/08/10 04:25 AM
Where is the cap, bolts and whats left of the rod?
Ive seen the bolts fail for one reason or another, rod cap come off, crank cuts the rod in half with the help of the block and then sends whats left of the rod right up into the head while its turning.

I have seen this failure also but the piston usually rips apart before the rod

I will have to check a couple hundred of Bill's posts, but I thought he had plenty of ring end gap, 0.021"? As long as it wasn't sprayed with nitrous.

X2 Some kind of suspected cause of failure would be nice to see, from those who have the parts in hand. Accidents happen but some kind of avoidance plan would be a helpful thing.

I'm not trying to hide anything.
I was trying to stay out of it as I still don't know what went wrong.
I haven't been out to the shop since my last post about the motor as all of my free time since then has been consumed with my daughters racing.
I need to get back out there but the situation with my job has left me very little free time on my hands and as such my girls and their cars have gotten the priority.
FWIW, I think the K 1 rods are a great product for a good price.

That would be the fault of the machinist and/or engine builder for not finding these problems before assembly. Very few rods made nowadays are useable right out of the box and all need to be checked prior to assembly.

Re: K-1 Technologies Conn Rods - 08/12/10 02:39 PM
Thanks Chip, exactly.
If all those things WERE wrong, then you still cant blame the rod. Its the person doing the measuring and assembly.My point again was, rods just dont fail all on their own.
I think most people knew what I meant.
Then again, what would I know about that, I've only built one engine in my lifetime.....
