Just wondering if it has been confirmed yet that the '09 model will put out 500hp.

nope. wait for the challenger to be released before any announcements are made about the srt8s getting the 6.4

With new ownership for Chrysler who knows what's really going to happen with future SRT8s let alone if there will continue to be an SRT division?

well i think SRT has been directly profitable (in addition to attracting buyers to base models) so it would be a bit of a surprise if they axed it

that said i think the CAFE requirements will be the undoing of this horsepower war...especially for a company like chrysler that doesn't move a lot of really fuel efficient vehicles
