This has been discussed to great lengths
...for the VQ30DE.
From what I can recall, nobody at maxima.org has noticed a lack of harmonic crank balance after installing a pulley, as the original pulley was not built to be a harmonic balancing element. It would still be wise to do some searches there before purchaseing a pulley to see if anybody has ever had a problem, other than some poorly manufactured pulleys that were cutting a grove in the crank seal. I have not been there in a while, so I have not been able to follow things.
Now, I'm not knowledgable of all the differences between the VQ30 and the VQ35, but it sounds better to start a search where guys have been doing it longer with a nearly identical engine. Just my $.02.

I'll post the pictue later on....wehave used pullies on the VQ motors since the pullies came out (Unorthodox is very local to us), and have never had an engine failure of any kind

FLY BY Z, no harm intended, it just seemed like you were dismissing the issue but later acknowledged it may be a problem. No harm no foul.

To answer the question of it being worth while for other pulleys..., my logic says, anytime I improve the drivetrain so that I get back power that I was previously being robbed of, it can't be bad. If it's a bang for the buck question, the primary pulley is widely recommended.

I bet statistically there are more motors with spun bearings without a crank pulley than there are with a crank pulley.
