The only thing done to my rods is having the ARP bolts installed and the rods re-sized. I'm trying to figure out how to build a jig that will allow me to do measurements of the weights of each end of the rods in a repeatable manner so that I can lighten the heavy ones to match the light one.

I find it kind of funny that the 4 rods I have has one that is lighter than the other 3, and the new set of 79mm pistons purchased from B-Projects has one piston that is a couple of grams lighter than the other 3. Go figure...

Good stuff Gary
Are your rods worked by any chance?
3 gsm is a fair bit out on the last one otherwise.

Looking at a14/5 rods they seem to be a good option if worked for an NA CA18de.
Rod comparisons....
best stocky rods are e15et but too long at 136.64mm c-c

I'll weigh my A15 rods with ARP bolts when I get home this afternoon and post results...

Update

The weights of the 4 stock A15 rods with ARP rod bolts and nuts installed, no bearings is-

514.32g
514.04g
514.00g
511.81g

You can shoot them depends with what ;)

But seriously I didnt know about the ca rods having thicker rod bolts.

I was actually considering using worked a14 rods with ARP rod bolts on a CA
thinking they are better than the ca18de/t rods by being a tad lighter round
the big end but thicker on the shaft.

Theres a picture somewhere comparing the A series rod with a ca rod.

I can't find my damn note book. I suspect that mrs A14force has "tidied" it away somewhere. I like to leave things where I put them, but she is like nah, I'm gonna hide your stuff.
Women, you can't live with them, and you can't shoot them!

AHAHA no one answerd hes question?

I think the best bit about the CA16 rods is that they use a 9mm rod bolt. So they are mad stronger right from the get go.

5gm difference in conrods can be the difference between winning a race or losing it.

If the engine has to accelerate 5 extra grams 30,000 times per minute that a significant amount of HP spent internally instead of going out the flywheel.

For a street car it matters not much.

The spool CA18 rods are 560 grams each with rod bolts (according to them)
but you probably knew that already

Ca16 rods are lighter than ca18 rods. Although at a glance you woulnt pick it. I have the numbers in a notebook somewhere. Which reminds me I haven't seen it for a while............
If it doesn't turn up soon ish, I'll reweigh some for you.
