Whats better for FI application, H-Beam or I-Beam?

 

H beam rods will handle more boost but they weight more than I beam rods. I guess it just depends on your goals.

 

I beams are a stronger product. I know the lunati I beam rods i had claimed 1500 hp rating and the H beam rods they sold were only 700-800 rated

however stock rods are strong to begin with so either H or I beam will work in your build well

 

exactly if you look at the high end stuff the i beam is usually rated for the most power.

im running the same rods in 427 as george mentioned (6.125 lunati pro billet i beam )

get something rated for your power , if you can find an i beam i would choose that . there are a few good choice in the 5-600 range and they can get as expensive as the pro billets ( 1500 ) and even go to aluminum rods which are big bucks and need to be replaced every so often.

 

depends on what they are made off too. a 4340 rod in H or I, the H are stronger. I -beams weigh less. billet I beams are stout!!

 

I’m going to have to agree with the other gentlemen, an I-Beam rod tends to be the best choice where price is not a concern, but not always. I say just buy the best 4340 rod that you can afford, while still being rated for you power level. There are definitely some quality pieces in both configurations. Some manufacturers such as Oliver only build and specialize in I-Beam rods. Crower is another that specializes in I-Beam rods, but also have them available in Titanium for those indiscriminant folks that just don’t have a budget and need the lightest possible combination of parts, but also can afford to change them out as necessary. Carrillo builds some terrific H-Beam rods.

I would choose a forged rod from just about any of the top manufacturers, as most of them have excellent products. I also prefer to purchase items from this continent, but some of even the best names out there are at least sourcing components off-shore and bringing them here to finish machine them. Their argument is the machining operations can be held to a higher tolerance by doing this while still keeping costs down, well what about all the other operations involved in manufacturing? Don’t get hung up on the whole billet deal, as a forged piece can and usually is stronger. Billet pieces are handy for one off or other custom pieces where it is too costly to set up dies, but is limited to the grain structure of the base metal. Whereas in forging, the grain structure can be controlled, ending in a superior product.
