Carrillo vs Pauter Rods
I'm sorry if this has been asked. But over the years, I seem to see more and more folks selecting Pauter rods vs the old Carrillo rod. Is it like the oil tread , where one person like X vs another?
Please educate me small brain. Thanks in advance for your reply. |

Carrillo rods - nice Japanese quality, some clearance issues on some combinations.
Pauter rods - Very nice American product, no clearance issues on any combination. Lots of other reasons but these are mine.

Carillo - Japanese?
Surely Carillo is owned by Pankl? |

I asked a similar question a year or so ago. I wondered why Carillo, which I'd understood to be the gold standard years ago, seemed to have been overtaken by Pauter. There weren't any responses indicating any quality issues with Carillo. And there was mention of Carillo being owned by Pankl now. Perhaps customer service is one reason. I haven't worked with either vendor firsthand, but I understand Pauter is good (and better than other vendors in general) in this respect.
There is a fundamental design difference between the two vendors' products. I don't have an informed opinion on this, but I think I have seen more opinions in favor of the H beam design that Carillo uses. Scott |

I asked because I've seen a Carrillo rod come apart in a Nissan...the whole engine was toast.

I can't answer that, its was an boosted GTR engine. When I asked them about why the rod broke in half...the supplier simply said that they needed a stronger rod.
I tend to think that Nissan motor was not turning say 9 + grand. One rod broke and took out the whole engine. I have Carrillo in another engine...and since I'm looking for a set of rods for a different projects. Thus the question. Last edited by 0396; 04-13-2016 at 12:26 PM.. |

I've seen plenty of rod failures and one cannot determine cause without doing detailed forensics.
![]() ![]() Rarely are good (Carrillo, Pauter, Arrow) rods are fault for metallurgical issues. In most cases, Human Factors lie at the root of the cause.

Steve, your probally correct as you build these motors day in and day out. But the motor in question was boosted to produce 1600 + hp. Im not sure if the rods in question was spec to hold up to that level of HP. I think that is why the vendor- they buy direct mentioned that they will need another version of their rods. Only one of six rods let loose.
Thanks Last edited by 0396; 04-13-2016 at 05:47 PM.. |

I'd say that may have something to do with it. That's like 4 bar at 7k rpm for a 3.8L. . |

I built a Ducati 748R engine and used Carrillo rods rather than the OEM Pankl Ti rods (due primarily to cost, the engine was going into an endurance race bike, and the fact that they only weighed a few grams more) - that engine spent over 40 track hours being shifted at 11.5k rpm during my ownership and no problems with the bottom end (this was around 2006 or so). It also did not lose any hp due to the slightly heavier rods (had to have the new, OEM crankshaft ballanced to suit them, however). Probably too much of an apples to oranges comparison to be of much use to the OP, butt just thought I would throw that out there . . .

I'm willing to bet the GTR turned far higher than 7K.
Most likely, just pointing out the ballpark kind of boost numbers involved. |

Carrillo Rods are American made I see huge boxes of them at the Blanchard Grinding facility I use and they are still 4340 Forged in Michigan.
There are Chinese look alikes such as Eagle Rods which can be a cost effective in use for Domestic engine kits. Scat is another company the uses the Chinese Rod for their product offering. regards |

I would like to add that this shop only uses Carrillo in there motors. But somehow this one rod of six happened to let go...as it cracked in half. For you that think oiling issue would cause the rod to break apart - please educate me.
This shop still uses the Carrillo rods on their lower HP buils. But I'm sure after talking to Carrillo they recommend another configuration of rods for their high HP application. |

I would think they "Carrillo" would recomend an Alumium Rod in Boosted applications the likelyhood
of a miss fire or premature ignition of the end gas in the cylinder would complicate things greatly. Al Rods are being used in Boat racing, Lucas Oil series off road etc. as well as the Shock Absorber for Drag racing. regards |
