Should be easily doable. Obviously theres guys doing it without needing much boost.
That would depend on the dyno and the operator. Baker Engineerings Dynojet reads a few percent higher than most Mustang dynos, not 20% higher. Their race cars show around 17% drivetrain loss.

A 408 will make more power than a 6.0 at a lower boost level. I didnt know Whipple was making a kit for the LSX engines yet? Or is it just the manifold and blower? Are they based on the car or truck accessories?
I would add a big blower before a smaller blower and turbo. A bigger blower will need an 8 or 10 rib belt configuration to get more than 10 psi.

I wouldnt get too caught up in the numbers... The track will be more representative of the true power output. I made 370rwhp on a mustang dyno with a completely stock 5.3 and radix 112. What have you ran at the track at the 400rwhp level and what is your race weight?
I dont know of too many people running aftermarket/ported factory heads with a blower set up. Most of the Maggie guys have used N20 as opposed to changing heads.

No I agree you can't compare numbers exactly but it gives you at least an estimate of what kind of power is being made.
I ran a 14.4 on my second try this summer. This was on heavy 24's also. I had never been to the track in my Denali before so I still had some room to improve. I was only running 7psi about 30-45 hp less than I have now. I've also changed to a built 4l80e since then and put on much lighter 20's.
I am not sure exactly what I would run right now but its definitely in the mid to low 13's. Last weekend I walked an evo8 which runs 13's stock. I have timed my 0-60 and its in the 4.2 range.
I would guess my race weight somewhere around 6500lbs.
I am debating on whether to build my engine into a 408 or just make it a forged 6.0 with heads,cams, etc.
