Then they are not being tuned correctly or using undersized blowers. I have seen/driven a few Whipple H.O. blown 5.4L’s that were making 440-475hp at the tires with no other modifications. The ones I drove were at the place I get my dyno work done.
A non-intercooled blower can’t make that much but choosing to buy a non intercooled blower is like shooting a toe off. The $$/hp ratio of the intercooler is fantastic.
4.6L motors make 400-450rwhp with just about every intercooled blower on the market except the Magnacharger. And the KB, Whipple, Saleen, Intercooled Vortech and the Procharger can all make 550rwhp with just a pulley change but would blow the rods out in short order.
A 5.4L can’t make that why?

i doubt 5.4's are making up to 475 to the wheels with just adding a blower.
i doubt even more that 4.6's are making up to 450 rwhp with just adding a blower. thats doubling the factory output (an extra 225-250!). i call BS!!! find some dynographs to prove what your saying. i can see them making 150 hp more or so but not that much.

No you sure as heck won't get there with a blower alone. Whipple only advertises 394rwhp on the 5.4 3v kit. I'd say there close. My first dyno pull ever was 400rwhp. Then came injectors and the custom tune.
that sounded bad!

That sounds about right. With a LOT of work!
I'm running 594rwhp with a KB at 16 psi on a 2V 5.4

he replaced the rods, pistons, valves, retainers, rings, bearings,arp head studs,ported heads, etc. one thing i didnt agree with but he did stick with the stock crank. so far its held up. is that normal?
