Garret themselves say on their website that the new "billet" wheels show no signs of improvment in spool or airflow... just cost more an look pretty...lol
Do you have a link to where you read that? I'd been curious how much of a weight difference there really was. I'd think a lighter stronger wheel would be capable of faster speeds. I know thats not always the case.
