I dont understand how the stock rod is soo small and heavy? I need to weigh 1G big rods because they are huge compared to evo rods. How much do you think the rod weight really matter?

I don't think you can quantify saving a pound or two on the rods as easily as you could saving 100# off the car. There are many benefits, though. Just not easily measured.

Here you go, I collated this info some time ago.

Wow - for some reason I never really put together that rods could have such different weight differences (well, obviously Ti will be lighter). Saving .63lbs per cylinder would seem like huge gains... not to mention the ability to rev much higher with that much less stress on the rod bolts.

How do I know what Rods I have?

I bought an evo 8 and it came with a forged engine but one pistons melted during tuning.

The weight of the rod is 615grams and it's slightly smaller than 150mm !

Anyone know how I can check what make it is? It has arp screws on it , if that's what you called them.

Post a picture of it from multiple angles...I'm sure someone here could identify it for you.

So.. essentially if the stock rods are 690 grams. Choosing anything below that should be a good weight savings.
For instance,
MAP Ultimate Duty Rods at 630 grams should be a very good upgrade?

The upgrade is that they are STRONGER and LIGHTER. If they were just lighter I wouldnt say it was worth it but stronger and lighter is a great upgrade.

My all time favorite is the Carrillo... I think it really made a difference on my setup...

I had weighted them at 574 grams on my digital scale

So my titanium rods at ~400gm will save about 1160gm, or about 2.5 pounds of rotating weight. Add that with lightweight Wiseco pistons and my superlight Winberg crankshaft and I can't wait to see how this thing performs. I guess we'll see if you can go "too light"

Just waiting to get the engine back from the machine shop in Cali. . .

What clutch? Marco used to say to add the weight back into the flywheel with a light rotating assembly.

I have an Exedy Compe-R that weighs 21#, so I would call it "mid-weight". Not as light as a Tilton carbon, yet 6-7 # lighter than a normal Exedy twin.
