Cunningham Titanium Rods
All Cunningham rods are made to order. We got lucky and saw these sitting on the shelf, otherwise they've got orders to fill for the rest of 2005 (we have 3 sets of regulars K20A(2) due May).
These Ti rods weigh 318g total and 222g rotational. They are rifle drilled for wristpin oiling and feature Cunningham's own 296,000psi rod bolts. They are 5.572" center to center, so we'll have a custom piston made with a shorter compression height to accomodate the longer rod. Without changing the stroke (86mm) - rod/stroke ratio is improved from 1.616 (stock) to 1.645 with the new rod length. They also feature a wider big end width at .938" which is the F20/F22C/H series B.E. width. So, we'll have the stock journals widened or have a custom crank made for the recipient K-series motor. Lastly, they are plasma coated to achieve 82c rockwell hardness.

Re: Cunningham Titanium Rods (edo)
Going by the specs, sounds like a titanium H23 rod set up at .938 width (F20C/H22/B18 are all .935).
Whats the price on Ti rods from cunningham, $400 each?

Re: Cunningham Titanium Rods (Innovation)
You're pretty close, they were originally ordered for a long rod non-vtec H-motor. I don't know my H-series very well, so you'd know better than I.
Normal Ti rods are 475/ea. These are rifle drilled so they're 525/ea.

Re: Cunningham Titanium Rods (edo)
For those asking how to hit 12,000+ RPM. This is it. A longer rod with improved R/S ratio and huge rod bolts. And oh yeah, they're light as f--k too!

Re: Cunningham Titanium Rods (ceLtic)
Cast? wow, thought they'd be machined, oh well... i thought titanium sucks as a metal choice since under rapid temperature changes its very brittle, anyone have comments?

The reason aluminum is the material of choice for the top pro teams. Aluminum rods are also 1/4 the price of titanium

Re: Cunningham Titanium Rods (edo)
Hey Edo
What compression height are you going to run. I don't drive a KA but I will be getting custom rods made. JE says they can make a piston with a 24mm compression height but im not clear if that's a full skirt 2 compression ring piston.

Theres soemthing wrong with your scale then, eagle 5.636 rods are around 530 grams

Re: Cunningham Titanium Rods (Innovation)
t likes to grab other metals...but i am sure you know this.aluminum is lighter than ti......but no where near as strong..plus the al rods are good for about 6-8 passes so they say.but ti...well till you sling one?
either way very nice rods.....

I can tell youve never actually used a set of alumunum rods.
Alumunum rods are good for a lot more the single digits in terms of passes. Jager rods are currently being tested in OE vehicles for longeivity and reliability. Jager was recently banned from the NHRA so they are now looking into other markets to market their products,The hemi and sport compact crowds included. Theyve been known to last quite a few miles with no problems what so ever.
BME, MGP and even Howards rods have been known to last well over 300 passes. As high as 600 in some cases.
The only downside is that they require more attention when in use and some MAJOR attention when the motor is being assembled. I run a system 1 filter with screen to keep an eye out for shavings or any material after any hard running of the motor. Its nothing out of the ordinary really, that kind of precaution should be taken anyway. Also, they are a lot bigger than ti or steel rods so they require some clearancing in some cases. The girdle/oil cradle needs to be modified or have spacers put in between the cradle and main caps for clearance. Thats not much of a big deal though. If it is a big deal for you, you probably shouldnt be using alumunum rods anyway.

That's why these rods are Titanium Nitride coated to prevent galling. I had my Titanium retainers coated to prevent that.
That's some sick **** right there!

If you're going to run JE, you'll have to speak to engineering and design a custom piston for your application. They'll need complete specs on your motor, especially what cams you're running. Without getting into the oil ring, it looks like we can run a 1.08" CH for our most aggressive cam, but we're still looking into where the necessary valve relief is in relation to the top ring.
