The 5.4L engine is a hell of a modding platform, and it's mature. It is the same engine that was in the Ford GT supercar.
If the 5.0L and 5.4L were running the same boost and compression, then your premise in the initial post would be true, but my guess is that the 5L is running both higher compression and boost.

My little 4.6L is putting down 467, so with the reverse calc for 15% drivetrain loss it would be rated at 550 crank, but I'm pretty much at the limit of what a 4.6 can do without labor intensive internals replacement (crank shaft/pistons/rods), I plan on going further, but at this point it would have been less expensive to have started with a GT500 to get to where I want to be.

yep, and hopefully since the 5.8 will just be a bored out 5.4 it wont have many issues such as the new 5.0 or 3.7 platform have.

I believe the boost of the 2012 5.4L is the same, but the compression is lower! It amazes me that Ford hasn't done better in putting a supercharger on some of the years of Shelbys! I drove three low mileage '08 5.4L Shelbys I thought about buying & was dissapointed! Frankly, all I could see was more torque off the line, but there wasn't much difference after 20 MPH in how they pulled for that engine size difference! I couldn't see the extra $25K I would have invested if I had gone that way in '08!

It's all a numbers game bro. Eventually there will come a point where the average car has 350hp or more and sports cars will be pushing average factory numbers north of 1,000+.

It's like anything else. If they pumped out higher hp cars with more performance now, which they easily could, where would that leave them for the next 10?15?20 years?

there IS a limit, 1000hp is utterly useless in any street car, only dedicated drag cars will find it useful running enormous tires that would never fit under a normal car. look at the veyron, hit the gas and you would be burning rubber all day and thats with 4 wheel drive and a ridiculously heavy body.

Some will have different ideas when gasoline hits $8.50 a gal! 750 HP you can't afford to drive, but will look nice in the garage!
