ATI is a quality piece, a true harmonic damper and will protect the crank, unlike some of the other manufacturers offerings.
I'm not sure if they offer an overdrive pulley option so you'll have to go to their site and look through the Y-car selections.

The link you posted is my car, that is the dyno from before I went with a 90mm TB and full 8 rib kit with an ECS belt tensioner. I believe the 8.5" is a typo, because as far as I know the crank pulley is the standard innovators west overdrive pulley. They never mentioned it being a custom piece. Your belt life will depend primarily on slip, with the 6 rib and OD crank pulley I was getting a little slip and chewed the existing belt in about 500 miles, but I'm not sure how many miles were on that belt before i went with the OD crank pulley. I have since gone to a 8 rib gates kevlar belt, the green one, and I have 5-6k on the belt with no belt dust or other signs of slip.
The only downside to a overdrive crank pulley I can think of is the possibility of adding more weight to the crank rotating assembly, Similar to a heavier flywheel. But the extra weight, if any, is minimal.

Very little, if you swap in just the overdrive crank pulley it does overdrive the accessories which could shorten their life. Although I wouldn't worry about it, consider this, when you cruise down the highway at 70 in 5th are you worried about over spinning your accessories? I'm not.
If you go with the full 8 rib kit from IW the new pulleys for the accessories are under driven so they run at stock rpm's.

I have seen wait4me install a smaller water pump pulley and run bigger than 8" but he said it was a lot of work. Plus, he was trying to feed air to a 427 through a TVS2300 I believe.
