Fiatnutz this is a great video. I'm wondering though. I assume that I have the type of connecting rod discussed as the 4.6L Ford and I have read from time and time again that if I use a supercharger, I should change over to forged connecting rods. What is your take on that? It looks like from your video that the 4.6L ones are good but you do mention that they can fracture. the forged ones look stronger to me, from just looking at them.

@FlatAbove732 - Get a set of forged or billet rods for use w/huffer.

Is there a front and a back to a connecting rod?

Yesterday I tore down a Chevy 2.2 LN2 and I noticed that the rods are not symetrical.

they have a "sort of tab" on one side but not the other?

[fiatnutz]

@ratrace2p51 - Yes, most rods go in an engine in a certain direction and you have to be mindful about how they are installed.

Nice discussion on connecting rods...I always learn a lot when I watch these videos! Is there much usage of composite rods like carbon fiber and do you see exotic metal rods like titanium or other metals? Thanks again for your informative videos!

[fiatnutz]

@tiddlywink100 - No carbon fiber rods yet, but I do see a few titanium LS7 rods. I'm glad you are learning from my videos.

@fiatnutz ... and recently I turbocharged my engine and I set to 11psi like (200hp) on t3t4 on those stocks rods, and they holds it perfectly; my question is do they kind of rods holds 18-25psi like (350hp), or I need some H billet forged rods like #4 rod in the comparison at 4:00??? My engine gears redline shift is at 6,500rpm Thanks.

@fiatnutz Hi man great video. I have a question for you: I have a 4G94 SOHC Lancer 2.0L this Lancer it comes with Forged Steel Rods but they are like the number #1 rod (from left to right of screen) at 4:00 comparison, so they looks really thin, but they are forged steel by the japanese mitsubishi factory...

I love all these videos about Costa Mesa R&D. I learn more and more...

[ratrace2p51]

OK, so what will tell me the "right" direction to install the rod.

I don't see anything in the Haynes manual, or onthe web in general.

Can you send me to a picture some where that will show the orinitation of the rod.
