I work for an alternator manufacturer. I look forward to nerding out over this pulley

Srsly you work for an alternator manufacturer? I've been working on figuring out if this would even fit the Celica for like....3 years off and on. Checking shaft dimensions, pulley applications, etc when I thought about it and wasn't already busy. Wasn't until I got a RockAuto closeout email that listed this Litens OAD rebranded as Dayco that said it would fit the Celica GT (because it fits later 1ZZ's) that I figured it would fit the GTS as well because Denso *probably* used the same alternator shaft because why wouldn't they? Good news is that I think they do because it's mounted. Now, I didn't have a way to hold the alternator shaft during assembly so here's to hoping that my 1300lb impact was able to smack on enough torque before the alternator rotating assembly spun (and the blue loctite) will be enough to hold it in place.
The OAD interested me because roughly 8-10lbs of mass at 3x crank speed is a lot of stored energy to slow down from 8,000 RPM to 5,000 RPM when shifting. It's a lot for the belt to absorb, it's a lot for the tensioner to absorb. And there must be some benefit to these devices for efficiency because it seems like every new car has one, maybe I'll pickup up a MPG, maybe it'll be able to shift a little faster, maybe my expensive belt tensioner will last longer, maybe I just wasted $40 and it'll do nothing. I'll find out later today probably.
