Which rods to take?

[Erikb]

Hi all,

I am looking for a set of stronger rods, I did some searching and came up with the following ones:

Eagle rods
Rods from 034efi

weight: 600 gram
Material: 4340 chromoly steel
Price: 685 euro for a set (+ shipping , import fees? + VAT?)

Arrow rods

weight: 530 grame (with bolts?)
Material: forged EN24 Material
Price: +/- 1200 euro for a set (+VAT+shipping)

SPM rods

weight: 550 gram (without the bolts)
Material: 4340 steel
Price: 641 euro for a set (+shipping)

Dahlback: Auto-verdi rods

weight: ???
Material: 30CrNiMo8
Price: 1605 euro (+shipping)

Quattro se rods

weight: ??
Material: 30CrNiMo8.
Price: 1455 euro (+shipping+VAT?)

Audspeed rods

weight: 597 gram
Material: 4340 chromoly steel
Price: 700 euro (+shipping)

Pauter

weight: 589 gram
Material: 4340 chromoly steel
Price: 747 euro (+shipping + VAT?)

Further on I found Cunningham, Crower, Eurospec and carrillo couldnt find a lot of information about there rods.

I have the idea that some of these rods are manufactured by the same company. Like the rods form dahlback and the rods from quattro se, both seems to be made by auto-verdi.

Regarding the eagle rods, audspeed rods and the SPM rods they all do seem to be the same but I am not sure.

All of them seem to made form 4340 steel or 30CrNiMo8 dont know if its the same qualitie and just another name for it.
All rods are strong enough to keep 700hp and all are about the same weight, most of them have the H-profile, only the pauter ones seems to be different.

Is there a lot of quality difference between the above mentioned? The ones from SPM seems to be the cheapest, especially because i can probably buy them without VAT (takes -25%)

Which one should you take?

[caterpillar]

spm ones.... the rod will NOT give you MORE power,then you can by another BIG turbo ,or bigger injectors,for the difference betveen the other rods

SPM look very good value for money.
Do you have a link for them?

[Erikb]

I was already thinking about the SPM's ones, here is the link for the http://www.stenparnermotor.se.

But why there is such a big difference in price between the auto-verdi rods and the SPM ones. There is a small bit of modell difference, but they are basically the same. Also the materials seems to be the same.

[Henka]

I believe with Auto Verdi, you buy more of a brandname than you do with SPM. SPM rods are suposed to be cheap. The Verdi rods are not supposed top notch - and therefore they're priced to seem the best. I'm going with a et of SPM's.

[Erikb]

I am also thinking of going for the spm ones, hope they can still sell them for the price they offer on there website.

Anybody know someone which tested them?

[Billman]

that are these material diferrences?

[caterpillar]

Spm Conrods

havent heard ANY broke SPM conrods ,if so ,someone have heard it,or seen it on some forums or

[Erikb]

I dont know if there is a big difference in 4340 steel and 30CrNiMo8. I believe the carrillo, which I found was the most expensive rod, is also made out of 4340 steel. I believe they say it can hold up to 1000 hp.
