Connecting Rod Questions

[s15specR]

Can someone with knowledge on connecting rods break down the differeneces between H, I and X beam rods, advantages.

Also what's recommended (Manley, Eagle, Brian Crower) for what HP, also I was told by a shop locally that Eagle H beams are good to 500hp.


Any help would be great.

I talked to eagle a while ago and they have upgraded the con rods bolts so now they are able to hold up to 900+ hp,

I forgot the size though to look for, give them a shout

I'm also running their Con rods. holding up 2+ years I like'em

Thanks for the info, thats good to know, when building a 400-450hp engine I rather use 600hp + capable connecting rods that 500hp max you know.

get a set of carillo rods with CARR bolts and call it a day.

first of all what is the intended use for the car? that question will dictate your rod choice more then how much hp it can hold. you can really judge a rod by the hp "capability." on a full out racin motor with high comp and revving close to 10,000rpm and making only about 250hp will have more rod loads then a motor making 450hp that is daily driven and barely see over 6000rpm if at all.

here is a good discussion i was a part of on SF about rods and just general discussions on them.

read it and then PM me if you have any more questions.
