Why a supercharger with the inherent parasitic losses?
The LSx V8 certainly doesn't need help with low end torque. A turbo setup would likely be lighter, yield better power, better fuel efficiency, and a smaller package.
Exact same thing I was thinking.
Now I'm wondering if I should cancel the Z06 order I have in and wait for this. Even if I'm spending a buck or a buck and a quarter for this, it's going to be what I'll end up striving for with the Z06. I'll probably have another 25-30 k in the Z06 to get it to this performance level.
I've got another 3 weeks to cancel it before it gets a production scheduled status. Once it gets that, it's mine.
The wife has been wanting a new Zo6 but I have been dragging my feet because I suspected Corvett would step it up at least one or two more levels before they had to level off because of either fuel costs or emmisions. If they can keep the price below 100K I will be interested.
I was just speculating nobody knows for shure until GM releases full details. Ford on the other hand don't use high compression somewere in the 8.8:1 with FI motors and have a low 8psi-ish boost. GM on the otherhand might do what you have stated high compression and with 5psi boost. From some of the spy pictures it looks like it will have dry sump and with todays tech I think it will have E85. Looking at the pictures I think the L92 is Al.

is there room for a turbo set up that wouldn't be rear mount? the blower atop this rascal has a built in intercooler.

Don't know about the packaging, I'm just a bigger fan of Turbo's than S/C's in general. From an efficiency standpoint, a turbo is simply a more elegant solution.
With smaller engines you trade-off between boost lag and peak power. Or, you engineer a more expensive solution like sequential turbo's of different size to smooth out power delivery.
With the LSx V8, you already have a very healthy torque curve and very good peak power. A relatively mild turbo setup seems like all that's needed to provide a nice boost to peak power while having minimal effect on driveability.
However, the guys at GM powertrain have been doing a fine job so far so I'll trust they've thought this through and made the right choices.
Hopefully GM when't twinscrew on this. Is this going to be GM's first high horsepower FI V8? GM has toyed around with turbos in the past GN's, Solstice, Sky, SyTy and had pretty good sucess doing it, well except for the turbo T/A's. I guess GM felt that this is the only way to meet fuel economy, emissions, more power, flexablity, durablity and NVH with this supercharger. Also I hope that this new car is just a add on to the Corvette fleet, that this is not a replacement for the Z06. Someone that is looking for alittle more power than a base Vett but don't want to spend the 100K+ doing it, the Z06 is the way to go. But someone that has deep pockets that want to put the woop'n on some high-end exotics can spend the 100k+ on the new beast.

From what I hear the Z06 is dead. The ZR1 is it's replacement. They will move the Z51 upscale to fill in the gap. I'm not sure if that means you will get the Z06 goodies on the Z51 now or not. But the last I heard is this is the last year for the Z06.
Also I agree with GM needing to have a school for prospective buyers of this car. They should set something up with Spring Mountain to teach people the respect that this thing is going to need. I'm guessing in the hands of a guy like Ranger this thing is going to be a low 10 second street car with well into the 200 mph area for a top speed. A guy that doesn't know what he's doing driving at 60 mph is probably 3 seconds from death in it.
