I think it's about time to toss this old classic into the mix:

Is it because there wasn't a steel sleeve?

Unorthodox Racing... Not Stillen/NST

No mention of Steel Sleeve in advertising, and no pictures of the backside of the pulley.

From: Unorthodox Racing Crank Pulley w/Belts, Great Pricing. Check it out!!

Description:Unorthodox Racing Ultra Accessory pulleys are included in our Ultra Street Sets or may be purchased separately. They are CNC-machined from light weight 6061-T6 aluminum billet. As with all Unorthodox Racing products, tolerances for each accessory pulley is held to within .001".

Off the record though, classic as it may be that isn't a VQ37... So it's not representative of this specific platform. Why? Because impact wrench.

6 pages and all it takes is a 5 second google, 3.43min of pure fun

SDOF Resonance Vibration Test - YouTube

It may not fail in 50k, but it sure wont last 200k. Since I generally don't keep cars for longer than 3 years, I would definitely use this mod myself, let the next owner worry about it.
