Another thing, the fricking CTS-V Coupe already beats the GT500 in straightline acceleration tests and has faster lap times around certain tracks (see Road & Track this month). If the Caddy can do that with 4238 lbs, then the Camaro Z/28 (with great tires, improved suspension, etc.) ought to be able to do that with its relatively svelt sub 4000 lbs.
P.S. I know it's not only about HP, but even though the CTS-V commands a higher price tag because of its luxury amenities (and VASTLY superior interior), people will not really be happy to pay $13K more for a slower car. Cadillac is GM's halo brand, and there needs to be a multitude of reasons to entice people to spend tens of thousands of dollars more for a Cadillac, over a similar Chevrolet (having the Caddy be the clear loser in the performance dept. is most definitely not the way to do that).
I think they will. CTS-V is catered to the more affluent crowd who'd like as much luxury with their performance car as much as they want the actual performance. I completely believe they are for two different markets and feel there is a distinguishable difference. Personally, I'd walk right be CTS-V for Z28 if I had the money, because that's just how I am. I don't really think GM is going to shoot to steal many sales from competitors - I'm thinking Z28 will be for the CAMARO-guys and gals out there. Of course - I want them to sell as many CAMAROs as they can, so I won't be disappointed if they shoot for as many people as possible.

I guess the best way to duplicate the Turbo's emissions and MPG is to engineer an S/C to do exactly what you explained above. Just as long as it doesn't affect the beautiful HP/TQ low end curve, that is something a Turbo cannot duplicate from the S/C.
They could take a page from the diesel's book and Twin Charge an engine (Super and Twin Turbo) but say good bye to your fuel mileage. Performance wise, it is very effective... but without diesel, gasoline won't see any advantages other than high output and a nearly flat curve.
Maybe bypass the Supercharger at a higher RPM when the Turbos are in full spool. Using the Supercharger to spool the Turbos, eliminating any lag the Turbos have and relieving the S/C at higher RPM for cooling... but who would attempt to engineer that monster... With 8:1 compression pistons, an extra 200+ lbs, two separate heat exchangers and a whine and hiss... might not be worth it but it would be neat to see on a gas engine.
either way, good info on the S/C bypass... something I can look into tonight.
I believe KB integrates their by-pass valve into a sort of "valet"-type mode, so you can manually control the boost so the undesirables who might have access to the car won't have full access to the power. I don't know about the Whipple and I don't know if Maggies feature a manual-type feature either.
