I was wondering which was stronger and which was lighter comparatively. Looking for real numbers here, not opinions.

H beams

Hbeams are usually heavier, from what I've seen.
Pauter makes one of the stronger rods and looks like it would be one of the lighter ones. Design is neither H or I type beam.

anybody have any tensile strength numbers?

b18sihatch

i know alot of mfgs have hte h beams over the I beams for strength

There's just more material on a H-beam rod vs an I-beam rod, and this is why they weight more. So I would assume the H-beam would be stronger if the materials are the same, say 4340 Steel....

b18sihatch

true, i wouild tihnk that taking off material would effect the integrity of the rod.

unless one rod was h beam e4340 and one was I beam titanium then maybe the titanium would be stronger even tho its a I beam?

But then again that would be comparing the integtites of the metals and not the rod itsself.

if both rods were titanium one was i and one was H, you would still get the ''well the h beam has more material so it must be stronger'' even tho both are from the same strong materials. the integrity might be greater with more material, and even greater if the rod is well balanced with more material.. thats just my theory

Mugencrxsir1

exactly

I-beam's are actually the stronger rod.. thus if both are made of the same materials and such..

you have to think about which area of the rod is receiving the most stress from each stroke.. its is not the front or back of the rod that takes the force.. its each side.. compare their designs

H < picture this as looking straight down on a rod cut in half.. notice that the force is only being displaced though 2 thin bars of material

like so:


notice how all the stress force is located across the 2 thin strips of steel

now look at an I beam.. in which the stress force is located over a much broader area

like so:




although don't get my wrong H-beams are very strong indeed..

but if you want to get technical about which one would be stronger/displace stress and combustion force better and more efficiently.. the I-beam would take the cake

Thats what I was thinking. I mean, think even of commercial building construction. Those huge pieces of steel are all I beam construction. And I dont even want to know how much titanium rods would cost!

on an eagle box it has a check mark for I beam or H beam but i never even seen ANY I beam eagle rods?

pauters are "X" beam or whatever.

im going to be running Tuner Toys I-beams and SRP pistons in my sohc build. should hold up to my hp goals pretty easy



next to a set of stock LS rods

i still cant forsee the i beams being structurally stronger than the H beam rods

SPOOLINmatt

has anybody bought any of the manley h beams yet to compare side by side between them and the eagle.

I assume the manleys can hold 700ish as well.
