Can't find any info out. At what power level have people had failures and what kind of setups. Inbox is fine if you don't want to post it here thanks

 

Great question greekc6!

Even though his inbox is working, post here please. I may consider this option also.

-Far as i know, most choose Carrillo today.

-Do we feel that paying more gives more with this?

-Has anyone conducted a "side by side" comparison far as composition of materials and strength?

-Rods cost nothing in comparison, to the labor. Choose it right the first time and forget it!

 

Need the H beam Carillo design with the Pauter rod cap

 

both rods cost about the same. within 100$. theres also l&n rods by one engineering but not many know about them. i guess I'm going to find the limits of the pauter rods since I'm shooting for as close to 1000 rwhp as i can get and i have the pauter rods.

some obvious differences. i bean vs h beam
zero oil pump clearancing needed on the pauter rods carillos need clearancing on 3 rods
carillo rods are slightly heavier

 

I am running Pauters. Very good product. I looked at both Carillo and Pauter when making my decision. Cost is not a factor as both are about the same.. Pauters are slightly lighter that Carillos which is a plus if using them in a higher rpm application. This was a big seller for me. The design of the Pauters also lends itself to less rotational drag. Finally, Pauter is also infinitely easier to work with when you need custom spec rods as was the case in my application since I'm running the double oiled RSR crank. It only took 2 weeks for Pauter to build a set of custom rods for me while Carillo was quoting 6+ weeks and a large up charge. No thank you. All these factors made the decision easy in my case as the Pauter was a better fit for my engine. Pauter quoted their rods to be good for 1200whp by the way. Both Carillo and Pauter are fantastic rods. Ultimately Carillo H beam is probably a slightly stronger rod but that is generally of zero consequence for 99% of applications which will be at 1000whp or under.

 

Both are fine for 1300whp all about the torque!

 

Great Reply! I would probably choose Carillo if this was the case though. Your point on the RSR shaft really makes sense in regards to longevity.

I'm confused on the rotational drag with Pauter. If the rod has less weight, I would think it would have slight less rotational drag unless, you alter the rod rotational angle.

Torque would be my concern as Anthony stated.

 

i would guess its not so much about weight but rather the shape of the rod. pauter is an Ibeam rod and carrillo is an Hbeam rod which might trap oil in the cavity causing slightly more drag

 

I don't see any chance of that happening at any RPM. Just because of that cavity there it doesn't mean it will keep any oil in there when rotating.

 

I dont mean it as it traps the oil but rather that its a cavity it has to travel thru vs a sloping design of the Ibeam rod. I dont know if any of it would have measurable difference

 

Highly doubt it. I would say no effect. However I have been around motor builds for a very long time. I don't know where all the fascination with H beam rods comes from as it is the I beam design that is the strongest. Pauter has a great design to be honest and I have no idea where the forums get the Carillo H beam superiority over Pauter unless it was influnced by vendors using them. Vendors don't always use parts as they are best keep that in mind. If anything considering all details Pauter has a better design of the two and should withstand the same torque levels as a Carillo. If you don't believe me send both out for a test to a 3rd party and confirm.

 

it may be because some of the early high hp engine builders for porsche motors had issues with the seating area for the rod bolt not being strong enough. they went to carillo and the issue disappeared. i actually have the pauter rods in my engine, not by choice but rather that was what the previous owner installed and that was because it didn't require any oil pump clearancing. my hopes are that they hold up well since this is a huge build with everything new and very costly to achieve the desired goals. time will tell

 

I don't think the difference in the rod bolt area between the two is of any significance between the two as both have plenty of material there. Early builds are also prone to failures due to learning curves and I would take those initial failures and conclusions around failures with a grain of salt.

 

Ive been running these rods for years across various cars with zero issues. https://www.pureperformancemotorspor...onnecting_rods

Just throwing a different brand into the mix.

 

See, the I beam design in there case is there strongest design, not H. Pauter is also an I beam rod, Carillo is an H beam design. Thanks for sharing that. Arrow and Manley are top shelf for anyone thinking of other options, more expensive than either Carillo, Pauter or the ones above.

My choice if going full custom on the 997 turbo would be a drop in I beam rod out of 300M material but there is much more than just that which goes into making the ultimate rod design.
