Light weight crank pulley?

[scionblack]

Are there any dangers in installing a light weight crank pulley?

Does it void the factory warranty?

Engine harmonics? (someone mentioned it to me? whatever.)

Also, I know it's lighter which is why it is easier to spin, but what are other advantages?

Thanks.

it's purely for hp - you won't "Feel" a difference necessarily on a tC...I know I didn't. xb1 owners claim to feel the difference, but for me, it was all top-end power.

as far as reliability, aftermarket crank pulleys have always had the stigma of transferring torsional vibrations, which could eventually damage bearings.

To be honest, the only time I've ever seen a crank pulley cause damage was on 700whp applications on older cars...

if anything does happen, it honestly won't be evident until you hit 200,000 miles.
