Most of all the H beam rods are being made in China with better known brands being finished in the US. The only issues I have seen with the Maxpeeding is sizing on the big end being off. If you measure everything though, all is repairable.
Wont aftermarket rods not influence the lubrication of the cylinder walls? Original GM rods had oil thrower tabs on the outer side (crank side of the bearing pocket) most aftermarket rods have nothing? Will I need to modify the rods with oil channels or the crank before use???
Honestly bro, I love your videos. I LOVE YOUR KNOWLEDGE!!! I’m coming from building SRTs to redoing my rustless Del sol. My question for you, I want 450WHP and I have obtained a b18c1 entire long block. What’s a budget minded piston rod set up for that ho range?
sound logic, subbed. what do you think about the cross beam or xbeam rods. interesting concept for sure. I know of one company here in the US that makes them.
maxspeeding rods are solid stressed the hell out of them in a sti made 650 lol and motors still running for 2 years of abuse and we all know how long a subaru motor lasts
Why would you not use an h beam rod in higher hp applications? I know of builders using them without issue in 2500 hp+ builds. H beam rods are stronger than I beam on compressive loads. I'm going back to steel rods in my build, and I'll be using H beam as well. I'm going to be in the neighborhood of 1600+ before I hit the bottle.
@@BC08 Here's a quote from Tom Molnar, regarding rods...He's forgotten more about con rods than most people have ever known...Message him sometime and talk with him....Here's the quote: With all rods, on the combustion cycle, you are trying to drive the wrist pin through the rod like a wedge splitting a log. An I-beam has the big, main beams in the sides which means they are not under the wrist pin. As that beam becomes over loaded, the thin section that IS under the pin crushes and the main beams blow out like a banana peel. Keep in mind, I have been designing rods for over 42 years including I-beams, parabolic beams and H-beams which means I can design anything I want. Look what I put my name on.
@@markgoulette5056 I know Tom and have run his rods in many engines. Amazingly good product for the money. However, FEA shows I-beams are superior at resisting compressive forces. Look at the form virtually every aluminum rods ever designed has taken and ask yourself once material strength is reduced why does every manufacturer choose the I-beam format?
@@BC08 I'm going to post another quote from Tom, but before I do, here's some information to chew on. First off, aluminum rods. It's a well known fact that aluminum is not, nor will it ever be as strong as steel. In order for an aluminum rod to have strength comparable to a steel rod, the mass of the rod must be at least doubled. Even at this, the aluminum rod is a sacrificial part, needing to be cycled out to prevent failure. Aluminum, as temperature increases, looses strength and becomes more "plastic". It's a popular rod for use in very high rpm/horsepower applications just for this reason. However, aluminum rods are NOT I beam configuration. They are a solid beam. Many versions will pocket mill the middle of the rod, but this is done to lighten the rod further, and when ultimate strength is not needed. Additionally, aluminum rods CANNOT be of the h beam design simply due to the fact that they cannot put enough mass into the rod in that configuration to achieve sufficient strength due to the material. Steel rods are a different matter altogether. First, they have virtually no cycle life, with the exception of extreme applications. Secondly, they not weaken as the temperature of the rod increases like aluminum does. Because of this, and it's comparable strength, beam design options can be considered. Tom has done the FEA analysis on all types of connecting rods, and went with H beam for a reason. You cannot cherry pick parts of data without showing the whole picture, and merely stating "FEA shows I beams superior" is doing exactly that. Tom is the original designer of the Oliver Parabolic I-beam rod, the K-1 H beam rods, and now his own line, Molnar rods. I think his background and experience speaks for itself, as well as his reputation for the product he delivers. Here's the quote from Tom as of this morning: "You cannot compare different designs when you you do not use the same material. FEA only shows you data based on what you input for loads. A lot of the FEA done on rods does not even include gap elements. I will also add that a lot of the H-beam rods are made wrong which is why they do not do well in FEA testing. The bottom line is, I will put our parts in the field vs failed parts up against ANY other rod on the market no matter where they originate including the very high priced rods on the market today." One last point. Carrillo makes what is considered one of the best connecting rods available today. They are the H beam design. Only recently have they started making i beam rods. Not because they are stronger, but because they can offer them at a lower cost due to near net forging, which requires less machining to finish the rods than a comparable h beam. You can do a google and pull up 10 different answers to the same question. Which is better for what? However, I'm going to listen to the people that actually do the design, testing, and manufacturing of the final product. Just an FYI, Carrillo also recommended an h beam rod for me, stating the I beam was not the better choice. I chose not to go with them simply due to cost. At $5000 for a set of rods, I can buy a lot of other parts and still have money left over.

The rods usually aren't the issue its clearances when people just toss it together and send it.

Maxspeeding rods FTW
If they're anything like their coilovers or turbos, it will be for the loss.
@@LostMoneyGarage they are direct copies of Eagle rods and use genuine ARP hardware. Proven time and time again.

Scat rods with nippon racing pistons
Maxxpeeding rods in my d16. They are shit hot. Im also puting them i my 800bhp k24

When you gonna test out the k20a3 rod bro from maxpeeding rod?
Whenever they decide to gimme a set. There’s a whole story there that it seems you missed

Hey which engine is better for boost K20A or K20A2?
How much u sell b18b1 scat rods with arp2000 bolts for bro?

That’s actually wrong. I-beam is stronger (per gram) when talking compressive loading.
