Aftermarket Rods?I beam vs H beam??

[EuroxS4]

So its a proven fact that I beam rods are superior in strength compared to H beam rods.Im just wondering if anyone here has tried RPM I beam rods??They are listed as lightweight but truth be told they are in fact heavier and stronger.All the builds I see,everyone is using h beam rods.Just looking to see if anyone is using RPM's I beam rods and how are they holding up.

When I poured over RPM's website I saw that the I-beams were not listed for the 2.7t but just about every other import platform.
Unless they just added them recently.

[EuroxS4]

under sport compact they are listed under vw.

VW 2.7L ULTRA-LIGHT I-BEAM ROD 6.063" B/E 2.269" 6PC/SET

I would like to know if they are indeed lighter or not.Same dimensions as the h beam rods.I-beam rods are normally stronger than h beam rods but also heavier.This is why im wondering about these i-beam rods.I-beam rods in general are far superior to h-beam rods.I am wondering if anyoen has run these and is this indeed the case??

From all the threads I've read on here the majority use their H-beam design.
Hopefully someone else chimes in with the info your looking for. Also just FYI
if you don't mind spending a little extra money IE just released their tuscan
I-beam rods.

[EuroxS4]

Anyone?

[zillarob]

Id be more worried about the strength of the block than the strength of the rods.

^^^ You'll never reach the limit of either rod before the engine block cracks, so it doesn't matter.

I have them, they are indeed lighter than the H beams, not sure about stronger but the 1.8t's put out 600 whp on these rods. that's 150 per rod so for us that would be 900.....don't think anyone here will push that limit..

You have it backwards I beam rods are usually lighter than H beam.

[landfill]

Yea I was wondering why he was saying I beam are heavier. They reduce weight from your rotating assembly.
As far as the I vs. H beam I think the H-beams will outlast your motor from what I've seen on here.

[924Carrera]

The reason I-beams are lighter is simple physics. The I-beam design is far superior for resisting shearing and bending around the x-axis than an H-beam. It's why they use steel I-beams in construction but you don't see them being turned 90 degrees and used as H-beams. To achieve the same degree of strength in an H-beam, more material has to be used, resulting in higher weight. I'm really not sure why aftermarket companies are making H-beams unless it's simply an easier and less expensive shape to manufacture. However, the H-beams that are available for the 2.7T are all very strong. It just makes more sense to get an I-beam if you are willing to pay extra because it will be lighter for the same increase in strength (notice how OEM rods are all I-beams).

[landfill]

From what I've seen you are correct. The H-beam design is considerably cheaper to manufacture. That's probably why they are still
being mass produced.

I think the real question here is wtf is Pauter smoking?

[EuroxS4]

Thanks for the input guys I do appreciate it.I have a BEL engine out of a a6 supposed to be stronger than apb.I believe the strongest is the diesel block from Europe.

I believe the casting are different internally.but I think BEL should be enough for me.

This guy^ didn't read the thread topic Posted about blocks in his rod thread.

American made with superb metallurgy and quality control ?

Easy killer. Wasn't a jab at Pauter. Just commenting on their unconventional design. Kind of like the topic of the thread, ya know?

[LINDW4LL]

So what is the consensus? The RPM I and H beam rods are essentially the same price.

[aysix]

What's the weight difference? Without balancing i'd probably stay with the H beams probably. If the I beams are significantly lighter then maybe they aren't worth it for just a rod swap.

Isn't that the op? I think he can change the topic of his thread whenever.

[spd579]

I chose the I beams because they're lighter.....no one ever bends aftermarket rods so the lighter the better IMO and less rotating mass to crack my block.

[EuroxS4]

Agreed to me the lighter the better if they are stronger that's just another reason to get them.The price isn't a whole lot more so why not.

That's my thinking, I just hadn't seen anyone running the RPM I-Beams which is why I was curious.

Same here.

[slow ride]

Can anyone answer what the actual weight difference is between the RPM I vs H? Sorry for the bump, but it's the right place for it.

[tasinb5s4]

I got RPM ultra light I beams they not installed yet !
They 60 gramm lighter (per rod ) then OEM 2.7 rod
They weight 525+_ 1 g with Arp bolts

[slow ride]

Excellent, thanks for the info.
