NEW Manley H-Tuff Rods compared to other rods
Manley has responded to the needs of the market by creating a new, stronger h-beam rod and we very excited to start using the new rod once it is available to the public. Our Power Factor SS shortblock will be using these rods as the new standard length h-beam rod which means phasing out of the MPS Budget H-beam.
Currently the plan for the new 'H-Tuff' rod is that it will be released in a few months. It should cost a little more than the current h-beam rod. The new rod is quite a bit heavier than the old rod so the choice will still be there to use either rod for builders. Some will prefer the lighter weight of the old rod while some will prefer the size of the new rod. I prefer the bigger size. I ran some dimension comparisons to other rods available on the market that we use here at MPS. All in all, the new Manley rod is what I would consider the best bang for the buck hands down. Comparison: Since I lack the ability to perform destructive testing on these rods, I can only resort to measurements. So I performed a bunch of measurements and put them into a spread sheet. Obviously there is more to a rod than just the measurements, like material quality, but geometry does matter. I measured the main beam in multiple locations. Since our Super H beam had a lot of taper to it, I wanted to be able to represent that. Starting at the small end I measured the thickness 10mm, 40mm and 70mm in an effort to portray a "profile". I also measured the thicknesses of all the legs of the "H" in the beam, the big end cap thickness on centerline, the small end, and the thinnest point of the big end where you see rods fail from high rpm. I don't think there is much more that I could have measured that would have been beneficial for this comparison. All in all, the data shows that the new H-Tuff is a serious rod and I look forward to seeing just how serious it is. Just to cover a few things again: The rods are not complete. This is a pre-production rod that was given to me by manley so that I may see the new forging. The final rod will also be available with 625+ rod bolts. Also, these are not scheduled to be released until March. Super Storm Sandy affected most of the east coast including New Jersey where Manley is located. Had that not occurred, these would probably be available now.

just did a search online and they are in the new Manley catalog. So I guess I'm posting data and pictures in a minute.

So I was planning on using your budget H beam rods for my build in the next month or two. Are you still selling them or should I wait for these new rods? Any ideas on the price I'm guessing $450-500 range.

I still have a lot of the MPS Budget rods in stock and the Manley rods aren't available yet. When they are available, I'll be using them when I'm out of budgets. Both rods cost the same. So I don't see a reason for me to continue carrying both. Plus, I don't want to have to have my own rods made forever in STD length. I've only been doing it because I didn't feel any of the rods around $500 were strong enough to be offered in our engines. My budget rods have only had one failure and that was at 622whp on a mustang dyno when two rods folded simultaneously. I am very excited to see a shelf rod option for $500 that I don't have to have built. My +2mm and +4mm rods are still going to be produced. Very soon I'll be offering a $500 +2mm rod with my engines again. I had to stop offering a budget +2mm rod because the process was changed and I didn't like the new design. They obviously had changed it to lower cost and sacrificed quality. Now thanks to Manley, I'll have a new rod to fill the hole... er gap..... in my product line. |

So everyone always talks about power when it comes to rods, but what about speed? You mentioned the big end of the rod being a weak point at high RPM. For my current build I'm only looking for low 400WHP, but I'd like to be able to spin it to 8K RPM. How do the two Manley H-beams compare to the I-beam as far as high RPM use is concerned? It seems that the I-beam still should be the best, but how will these H-beams handle an 8K redline?
Thanks for the info! |

The new h beams are going to handle 8k no problem. I've seen the normal h beams run to 7800 and that engine had around 20k on it.

Can you add a squirter to the big end of your rods? Or do those not make much difference?

That does not mean EVERY factory liner will hold that kind of power.

Do you have the total weight and pin/big end weights?
I'd heard of these through a beta-tester shortly before x-mas but he didn't have a scale. Regardless, it seems like a nice and cheap rod option for the platform. |

I can't wait to get my hands on these. They are going to be a game changer in the connecting rod department.

Dom would you mind posting a picture comparing the H tuff next to a stock EJ257 rod? or stock vs Manley H vs Manley H tuff?
We are hearing 3 weeks ETA for production units. |

Oh damn, you knocked it out of the park. Thank you.
Loving that custom rod. It looks like it is leaning over to throw up after a night of drinking ethanol. |

oh that rod was just cruising down the highway when it decided to bend itself.... says the teenage customer. It's a rod for stroking the BRZ and getting around the cylinder liners |

It was easy. I just swapped in a new block for a customer and let him drive it on a break in map. He was very interested in how our rev limits worked. He didn't realize that when the tach stops at 5500rpm it doesn't mean that the engine has stopped accelerating even though he continued to downshift while going down the highway...
