I think I was under the mistaken impression that you must replace the crankshaft pulley.

I understand very well that boost is affected by a larger crankshaft pulley or smaller snout pulley. It wasn’t clear to me if the pulleys were offset on them.

My kit came with what appeared to be an unused JRSC high boost crank shaft pulley which I understand many people fear since its not dampened.
I believe the offset was only on some motors, but i can't remember which - possibly later models? I don't think the A6 needed to run it though, i believe their offset is the same as my motor.
