Conrod Weights - Information Thread

I thought it may be a good idea to collate all the weights of the conrods that are available today in one thread. This will help people make an informed choice comparing one against the other when its comes to there build parts. I did a little search and have obtained various weights from the threads I discovered, some weights maybe incorrect so feel free to correct them.

The table attached is based below on the 3 most popular lengths that people use on Evo engines.

Feel Free to add your information but please.... facts only, no guessing

Lets keep the thread CLEAN, no discussion on benefits / downfalls etc just rod weights

Data replaced with PDF

Are the Crower and Oliver rods I beam? If yes they are lighter than I thought.

Going off at a slight, but relevant tangent

OEM rods on an Evo 7/8 have a minimum weight of 618/9g

OEM Evo 10 = 579g

Pics of an even lighter weight 162mm rod R&R are making for us.
This is the GENUINE weight of this 162mm rod with ARP625 bolts. Pretty cool I think :-)

It is an even lighter weight version we are testing. See second pic for where the material has been removed

As a side note; weight above the the parting line is really where you need to be looking :-)

The (stock) 150mm version of this rod will be around 530grams & at least 800bhp capable.

Ti is being used in many motorsport applications already. Alot more thought is needed due to the way different matearials disapate heat and react under load. For instance the rod bolt used with a ti rod is important. Without a doubt ti rods are going to be making their way into u.k builds soon.

The cost when using the properly r&d'd and engineered components sort of makes it not so appealing for your average enthusiast who likes paying 600-900 for rods.
Kind regards,
Gum

Add the rod bolt used then once the info is compiled make it a sticky. Add crankshaft weights (stock and billet).

Regards,
