Balancing con rods

I'm going through the process of getting my parts together to build a 4B11T for an Evo X and have a nice shiny set of rods and pistons sat here.

After procuring a couple of 0.01g accuracy scales I am preparing start balancing these before having the crank balanced. With the rods I am now wondering if I need a fancy bracket at all (although I had been wondering about using a STI stand??) and could simply use 2 scales as per my picture?

I appreciate that there is very likely a good reason for not doing it this way, so before I go reinventing the wheel I thought I'd seek some advice!

Thanks,

Adam

Hi.

To me it's overkill. Making sure that every piston and connecting rod pair has the same total weight should be good enough. Balancing rods along with entire rotating assembly is kinda level of precision that a V8 engine would need, not streight 4 or 6... I don't think it's really necessary in your case. I've never done it on 4g nor 4b engines without any problem...

For the most part, I'd 100% agree with Shota, especially if the rods are from a company with a reputation for accurately produced products with close tolerances - unfortunately not true for all of them, but that also depends on how fussy one is.

The problem with end-end balancing is that there HAS to be consistency in positioning the rods' centres to the load points. If one of the load points is slightly nearer or further from the other, it will affect the loads.

In your case, the rods do appear to be machined well enough to use your method, with caution.
