Numbers are about what any 4.6L makes with a blower and boost turned up. A 2V with a basic S trim will make damn near that, pump the boost up and it'll hit 500 as well. The rods are on borrowed time at those numbers tho.
No not everyone wants a Coyote, I'm just saying that don't get carried away with dyno numbers and thinking you can just drop a blower on a 4.6L and beat up on Coyotes, not gonna happen. Plenty of dudes at "cars and coffee" with dyno slips that have no idea what their car would actually run at the track and likely would lose badly to a car making less power that is actually properly setup.
There is something to be said about not having a car payment or $$$ insurance but you still need to pay to play. Swapping to a Gen2 Coyote engine is a lot cheaper than a blower build, is a complete drop in at this point in the game, will make big numbers and even get great gas mileage to boot.
The PD blower does sound great.

Just because I give you advice, doesn't mean I know more than you. Its just means I've done more stupid ****.
