Hey yall I was wanting to know if anyone knew the hp rating of these rods? K1 TECHNOLOGIES CH6125ALLB-LS8S. These seem to be decently price billet h beams. Are there any other companies in this range or better?

I just bought the exacte set and plan on pushing 1300fwhp through them,

K1 doesn't put a hp range on their stuff. Too many other factors to consider like rpm's. I did send them an email asking about the same rods. Told them I'm looking to make 11-1200hp and they told me they would be a good choice.....take that for what it's worth. Sometimes you get what you pay for, but I have heard a lot of good feedback about K1. So I'm gonna buy Callies "I" beams for piece of mind and I know what they will hold.

Imo most "hp" ratings on hard parts are underated when applied to a FI application. Reason being that FI power is spread over more degrees of crank rotation. Ie longer burn time per power stroke. I have had engines na or n2o that have blown and then been able to achieve 20-30% more power when turbocharged with the same combination of parts. Like I said just my opinion. Sure someone will have a contradictory one but I have seen it first hand.
As for your specific question ni am not familiar with those rods but almost and will probably handle more than 90% or us will ever need.

What is your hp and rpm goal with your motor?

very true... alot play in the hp rating of a rod, a bad tune, bad fuel system will kill even a set of callies/oliver rods

I'm looking for no more than 750-800

i have a set of these rods going in my 365" ls2. looking to make 1200hp with twin turbos. this is going in a dragster. was going to use the k1 crank as well, but i am thinking of trying it with the stocker. make sure you get the arp 2000 bolts minimum. the first set i ordered, had 8740 bolts. sent them back and got the ones with 2000's.

So your going to use the stock crank for 1200 hp? Do you like throwing away money? I would just wait till you can affortd a good quality crank. Because IMO durability starts with the crank and moves up the chain from there.

The stock crank is a quality piece. Lots of us here pushing them hard. Fwiw, my rods are rated for 650hp and I've been running them for five years now with no issues. Making right at 1000hp now, and most of that five years was at around 800hp.

thinking and doing are two different things, but show me a stock crank that has failed with a turbo setup. besides, i am only pushing a 1650lbs car down the track. hp is not was kills a crank, it is what is attached to the end of it resisting it from rotating. a 3400lbs car at 1200hp will hurt a crank well before a 1650lbs at 1200hp will. i know it will be harder on bearings, but i will be tearing it down way more often than alot of guys.
back to this thread, the k1 rods are quality pieces, but every one is marked made in china. but then again so are eagles and compstars. alot of guys are running those rods with good results.

Wht would be a good kit for like 4.190 bore and 4.250 stroke that would be reliable and wallet friendly?

Reliable "and" wallet friendly cannot be used in the same sentence!

LS_Dreamin'

So what exactly would you suggest for the least amount of money possible? not cheap but reliable for less
