What do you think about Eagle Rods

My only comment here is on the mention of titanium rods.
They would kick alot of ass, leaps and bounds better than any steel rod you could possibly make. Ti has the highest strength to wieght ratio of any metal.
The reasons that it's not commonly done is because the market value of titanium is quite unreasonably high. Also, titanium is umung the hardest materials to work into tight tolorances, it's difficult and expensive... it's possible, but wildly expensive. To forge titanium requires much higher tempratures than steel, and much much larger equipment. Ti alloys (as well as many other high strength metals) also has a slight "memory" (similair to spring steel) that must be taken into consideration during manufacture.
Forging steel into shapes requires low tempratures and tiny equipment to get very nice tolerances... Ti just isn't feasable, which is why, I think, it's not commonly done. Perhaps Ferrari is doing it in their F1 cars, but in a Supra, the rods would cost more than the whole car and the difference would hardly be objectively measurable.

Well it depends on how much you paid for your car..
Mine were not more than what I paid for mine :icon_razz I work with many metals and would agree with much of what you said. Sometimes people like overkill parts to withstand anything :naughty:
Pic as requested but not good quality (sorry, only one I have) I don't remember the weight but can find out.
My Titanium rifle drilled rods for the 7M

Cunningham makes Titanium rods but mine were custom made for the 7M. They have also been rifle drilled.

i guess so does pauter, first thing searching came up with..
http://www.pauter.com/titanium.htm
tho i couldn't find 7m rods even in chromly on their site ???

No need to feel that way..I like custom parts :naughty:
pimptrizkit said:
Yes they make Ti but not for the 7M. They will need to be custom made (as mentioned on the site)

They make them.
I have a custom set in my engine
They also have them off the shelf parts.
btw I have to jump on with IJ.
Sorry all you weight watchers are dead wrong. Unlike the crank that is a rotational mass, the rods are reciprocating mass (up and down with a bit of side to side deflection). In otherwords cutting out 200 grams won't make you rev higher or faster. And it sure as hell will not affect rotating mass. and that weight diff. 100 grams. I highly doubt it is more than 50 gram diff.

no
they should put ZERO loads on the bearings if the lubricating system is working properly. Now if the lubrication system is not working properly, then the rods weight becomes irrelevant as the bearing gets disintergrated.
So try again
Lots of "theory" here and very little real world experience.......
It's nice to bench race but the reality is most of the "gains" people rave about are placebo nothing more and fall within the +- of most chassis dyno's.

What else do you have in stock??!!
thanks for weighing!
how close were they to eachother? +/- 2 grams?
Hmm, missed that.....
I didn't expect to find triva about a Mitsu here.
The eagles were all within +/- 1 gram per set.
Note, this does not mean within one gram, but actually a spread of 2 grams.
I went through them all to see how close I coumd get on 6 out of 12.
One set had 3) identical, 2) +.8, and 1) +1.
The other set was 5 within some miniscule amount, and 1) 1.3 grams lighter.
Unfortunately, the 2 sets were several grams different frome each other, so mixing & matching to come up with a 'perfect set' was not possible.
So I am going to have to spend time ballancing rods.........
( I am a bit of a perfectionist, I want those suckers within .1 gram, not a full gram).
As far as what else I have.........
Not much, a few hundred valve shims,
A good used set of ROSS pistons.
A pair of stock cams that have been moly coated.
Helical LSD
F-con
VPC
A genuine Group-A throttle (65mm), full dia. throttle tube, and turbo (larger than the standard CT26).
And probably other bits & pieces.
A buddy of mine with health problems is going to unload some of his stuff on me. He has cams, a TODA shim under set, and OS flywheel, A Big A$$ TD-08 turbo.
But until I actually have it all here, that is just so much hot air......
