Is one of these weighted pulleys a worthwhile addition to an offroad vehicle?
I've just purchased a new engine and need to add a pulley to it. I was looking for a replacement sand seal so I can run the kit I have on my current engine when I stumbled on this.

More rotational inertia should give better low down torque correct? Or is it not the norm to run one of these unless you have a lightened flywheel??

I believe they just balance the crankshaft better...

Maybe they are used mainly with counterweighted crankshafts??

Still sounds like a good idea... [like two flywheels}

I would like to see some facts and figures

more weight means more energy to turn it

just my opinon

Bergs recommendations are to run the extra weight on a C?W crank and lightened flywheel. The extra mass is to help absorb engine harmonics. Proof.....dunno about that, although I would use one esp. with an extra light flywheel. What engine combo have you bought?

I would have thought that if it works as advertised (remembering that most cars on the road have harmonic balancers), then wouldnt it be more beneficial on a non c/w crank.

ie - Doesnt a C/W crank already help with the vibration / haromincs issue.

Sounds like a good combo. In that case, if you like it, I'd go for it. The mass won't hurt the baja and steel wont wear quickly like the non-annodised alloy ones.
