How's that a exception? Hince more power going into these engines. Locally in the last year I have seen 3 trucks with Carrillo rods take out blocks. 2 Cummins and 1 Dmax. Witch is odd cause tuning keeps improving. I'm just going off of what I see at the track. I am glad I paid a little extra for better rods on my build.



I dunno if I buy the tuning getting better thing. Maybe for the big builds and guys putting time in on the dyno.

But for the average joe with a mild build as in under 1000hp, there seems to be a lot of cookie cutter tuning coming out from everyone. And alot more supposed tuners that don’t really know what they are doing. It also seems to be getting increasingly hard to get tunes changed or fixed. All this I feel is putting more strain on parts that previously held up fine.

Good tuning for sure helps things last-like that dude on here running 9’s with a stock bottom end or whatever it is.

Yes, building an engine for the UCC is the exception. Absolute max effort performance, pushed right to the ragged edge for three days of pounding is not the other 99% of the people out there.

If you tell me that a guy with an 800rwhp truck has bent a set of Carillos, I'll come back with, "Ok, what other part of his build or tuning caused the problem?" Its not normal, at least not with Carillo's reputation for quality parts, so the root cause should be delved into further, b/c otherwise its just poor diagnosing on the mechanic's part.

More then one Duramax engine has failed with Carrillo’s with different tuners and different builders. Just because it’s not on the internet things can and do happen everyday. I doubt it was Guy Tripp or Marks Fault in the build I was involved in. Internet speculation gets nothing accomplished. Parts fail it is what it is. Everyone learns from it and the industry is better from it.

Oh I'm not saying it doesn't happen, shit happens I understand but just very uncommon, I pointing out the fact Mr negative Nancy was trying to say it happens all the time. I agree with Tom UCC is the exception.

I think we’re seeing more rpm and horse power than ever before. Big heavy parts at high rpm, high hp and torque are destined to fail at some point. I certainly wouldn’t blame the rod without knowing all the info behind the build/use.

I'm negative for pointing out what I have seen lately?

Most guys did NOT build trucks just for UCC. Get to more events and you will see most of the trucks in person. Interact with fellow racers. Tom. I like reading your comments how you would rather not attend these events..... That's where knowledge is learned.

As for tuning. If Mark is making stock bottom end trucks go 9s then that should say something......

But what do I know. Just a idiot.

I would like to cut up some failed rods and see what they got going on inside them, if anyone can get some, I'll pick up the shipping.

I just think it’s funny that the OP in the original WTB thread hasn’t even replied to any of this :roflmao:

...which is exactly why I went on a rant. A response was entered without there being a question in the first place...:rofl:

DO YOU HAVE RODS FOR SALE was the only relevant information needed.

This post actually cracks me up because lately I have seen many Carrilllo rod failures. I think we are getting to the power levels where they don't hold up.

How is the Carrillo HD rod holding up at that point? I know hey designed and released a new rod just for the 3k hp crowd.

Has anyone chunked a set of Waglers billets yet? My first set was far from perfect there was tollerance issues, called them and they made everything right sent me a new set and re balanced my rotating assembly at no cost to me. They paid to ship my complete rotating assembly both ways from NV I thought that was going above/beyond to make things right.

Until we get some info back on these recent failures of three sets of Carillo's it would be 100% speculation on the issues. First failure was Tony's UCC motor on my engine dyno and it was a used parts motor that was no stranger to 1600hp. He refreshed it and fixed a few problems he found when he opened it up. It made 1700+hp 2700ftlbs during testing on the dyno then spit a rod out the side at 1580hp with no reason for the failure but tore a bunch of crap up when it let go. It was purely a rod failure best the piston was still in the bore intact with wrist pin and all. At UCC we unfortunately watched Eric Merchant along with Mike Graves spit rods also. I can't speak on behalf of Eric's but on Mike's it was no where near the power level to be worried about it happening as we were only on tune3 fuel only when it let go. Yes it was making some serious power because it was on a pass when it popped. Up until these issues I have not had a single worry about these rods because I have beat the crap out of them at 1800hp 2300-2500ftlbs on the engine dyno without issues yet. Blocks have been the issue above 1400hp range and that has been more of my personal concern with these motors. Watching these rod issues lately leaves me feeling slightly uneasy but I hope it is just a fluke in the parts. As alluded to before, making a stock motor run a 9 sec pass is extremely difficult and was no accident as it was cylinder pressure based tuning that got us there and all of my tuning is based on the knowledge I have learned on both of my dyno's doing the cylinder pressure monitoring during tuning to relieve as much stress as possible on the motors while making the most hp as possible. With that being said I don't like the fact that parts have failed in built motors that on paper shouldn't have happened in my eyes. Only time will tell on this matter but I'm hoping for the best on it.:hug:

The rpms aren’t an issue at all. If it was we would be spinning bearings. Cylinder pressure/torque is what gets them in trouble.

Mark, do you know if anyone has sent rods in for analysis? Did they go back to Carrillo or an independent party? I would be interested to hear what was determined to be the cause of the failure. It would be nice if someone could send a failed rod or three to Mat to let him take a look. With his knowledge in metallurgy, engineering, and engines, I bet he could give some reliable information that would be untainted by a monetary influenced bias.

As for the comment on the Carrillo HD rods, it was my understanding they were only making those for the Cummins crowd right now.
