What are the differences?

i.e. -

manufacturing
ways to distinguish the two
application(s)

Which, if any, would require the block to be notched?

Thx

I-beam



H-beam



dunno what the advantage of one over the other is though...
i-beam is better for twisting forces... h-beam better for pressure... if i remember correctly...

thanks man...anyone else have anythin to contribute?

I beams are basically a lightened H-beam, pretty much only for all motor applications. Identified by the thinner section in the middle for weight savings.
H beams are made to take a lot of power and the extra weight is nothing for reliablity assurance. Look like a basic rod.
X beams (pauter) are beefed up H beams, built to weigh a little more but can take alot more power. Looks like an H beam with an additional "support beam/brace".

All forged rods are made thru the same forging process and most aftermarket rods are close to the same width and usually only require block notching on D's or weird combo B's (b16 w/ an LS crank).

i found that...thanks tho...good read has some more info. http://www.eng-tips.com/viewth...ge=28

I was under the impression that:

I beam were the stronger item?

H beam were higher reving because of the slimer design?

idk, but my manley turbo tuffs are I beams

based on that, i'd imagine that the I-beams are stronger than H-beams. That's how i thought it always was, but i'm waiting for someone w/ a little more technical input in this thread

bump for more info

I am under the impression that an all motor setup would benefit from an H beam, as the load increase is constant, unlike boost where there is a spiked load after the turbo is fully spooled...therefore an I beam would be better. also the H beam has less material in-between so there will be different lateral loads on each 'lip' of the rod which sounds kinda shady...can someone verify this?

honestly buy what you like then get it cryo-treated and TRY to break it if you can im sure you it will take more abuse than you could ever throw at it

I'll break it down again, this time with pictures
All this info should be right, but correct me if I'm wrong anywhere and I'll edit it accordingly

I beams (or A beams with Carrillo) are basically lightened H-beams and meant for allmotor apps where saving a few grams can help performance and still give you reliablilty. I'm not sure of other companies but I know thte Carrillo A-beam (basically an I-beam) is made from the same blank as their H-beams.

H beams are a little heavier/beefier which is needed to support more power, as the more power you're pushing the higher the cylinder pressure at detonation. I think it's pretty obvious when you look at an H-beam vs an I-beam which is heavier, and if it's the same company's rod, which is stronger.
Carrillo's strongest rod:

X beams are made by Pauter, i think they're the only company, and are basically beefed up H-beams.

The streamlined contour also provides subtle benefits in the form of windage reduction. The main beam rib itself continues around the wrist pin boss, perfectly integrating the beam to the pin boss, a small but important contribution to overall structural unity</TD></TR></TABLE>
Pauter vs Eagle

if i put eagle rods on my ls engine( stock) would i need to notch the block?

no notching is needed.
