Hope you write up a good review. Are you planning on doing any specific testing?
I have a fluidampr waiting to go in once my fensport pulleys show up and I get some free time hopefully in next few weeks. Probably do the the lightweight shorai battery at same time, got to stack those little gains together to make the butt dyno happier.

I wasn't planning to do a dyno. My main concern is reducing vibrations and I was only planning to use my butt-dyno for that

I could do a couple 0-60 pulls or do a before-after virtual dyno while at it. I will be most happy if I see a smoother running engine. If I haven't made clear yet, my engine is sc'd with JRSC.
Edit: and I agree, stock crank pulley clearly has a dampener. It is not a single-piece metal design.
