H Beam vs I Beam Connecting Rods | Which is For Your Build?

What engine internals do you want to learn about next? Comment down below!

I'm going with H beams and going to push 40lbs of boost h beam handle side load better which boosted applications have

Aluminum has no endurance limit meaning it will fail and get weaker over time. Steel will hold its fatigue in the same spot indefinitely.

😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂 I think someone got the Teleprompter sideways are something better redo this one

Hbeam Eagle rods here! 38psi 650hp/500tq running strong.

I was also told I beams are lighter and better for n/an and H berms dominate the boosted world?

Do NOT listen to this guy. He doesn't even cover aluminum rod stretch. Typically, aluminum rods MUST be replaced once a season, due to rod stretch. If you want longevity, always go with a steel rod. I say this, because none of us can afford the best rod out there, which is titanium.

This dude is completel wrong! He claims that the longer rod will wear out sooner than a shorter rod, because it has a 'larger deflection' than a shorter rod. This is completely false. It's the exact opposite. Now lets talk about piston speed... Yes, piston speed is the determining factor for piston integrity. A shorter rod will cause a piston to increase speed through it's stroke faster and higher tian a long rod.

I don't know why anyone would create such a falsehood of a video. Longer rods are always better, for the reasons I listed above, not to mention that your timing advance is more forgiving. The only downside to a long rod motor is oil ring to wrist pin clearance. But with modern technology, and the ability to manufacture very short pistons, it's all the better to long rod your motor.

Some of the information here don't sound right imo

12 months with Eagle Rods on 39 psi, fully built Evo 8 at 650hp/505tq on e85, just pulled out and inspected last week and still in great condition. The most important step in making them last is getting them re-sized by a machine shop, because the majority of the time the clearances on the big end are to tight or to loose right out of the box. You HAVE to get them checked! The people who Ive seen with blown motors running Eagle rods just "dropped them in" and didnt pull bearings after to inspect the wear.

Misinformation mate. On N54 engine tho the rods are forged they still bend, so in theory of boosted applications the H beam handles the abuse better than I beam.

how mush would the eagle beam hold? .i just resently get the h beam for a rb25 engine

Good information 👌🏾

Wont aftermarket rods not influence the lubrication of the cylinder walls? Original GM rods had oil thrower tabs on the outer side (crank side of the bearing pocket) most aftermarket rods have nothing? Will I need to modify the rods with oil channels or the crank before use????

What are your thoughts on the Manley H Tuff rods for turbo applications?

I want h beam rods for my nissan 3.0l maxima

Sorry, but by in large, longer rods use lighter pistons, and cause less side load, hence less wear and tear on components! Longer rods have many more advantages over shorter rods.

How about the boostline rods? Do you guys have experience with them.

The Short Rod and Long Rod limitations are switched… Longer Rod increased dwell times and better Rod/Stroke Ratio… meaning higher RPM and Rev friendly.

I think there was a lot of misinformation or oversimplification in this video

I'm guessing aluminum rods isn't meant to be DD

Really enjoyed this, tons of great info, I learned a lot

That's what SHE SAID !!!!!

The longer the rod the faster piston speed to giving RPM and the higher the torque.

What is the maximum value that you consider as low RPM? 7-8K?

Yes.
