You have so many options with an ATI from the durrometer rubbers to adding crank triggers I can't even list them all ... to being fully rebuild-able. They are the damper of choice for professional race teams.
Its bolted together from cnc machined parts and can not come apart in the same way others do come apart. ( Most of the others are cast)
Cheap *** pulley's are not in the same league.
Powerbond ..... is bonded where the ATI is bolted and can not fail in the same way a bonded pulley can fail.
Weight.. the ATI is lighter
Design, machining, rubber, assembly.... its night and day.

Thanks for the info.
Slows down accessories? I'm doing a cam swap this month, and I've called several speed shops to inquire about an underdrive pulley.
The majority mentioned that for a daily driver (as mine is), a 25% underdrive pulley would affect the charging of the alternator and could also possibly lead to overheating in the warmer months (as the pulley slows down the waterpump).
I suppose an overdrive alternator pulley would combat this, but wouldn't that defeat the purpose of freeing up hp?
I've been recommended a 10% underdrive, but would that even be worth the money?
Guys with pulleys, is this the case? From what I've read on the board, this doesn't always seem to be an issue, but is it worth taking the chance for 7ish hp?
Thoughts? Input?
