You guys crack me up.....The Z06.....no A6. The E-Force, can be had with a warranty. That was my most important decision to go E-Force on my '12 GS. The dealer installed it, and its covered by GM for everything but the drivetrain, and that is covered by Edelbrock.
Its the safest and easiest way to get the RWHP you want, who cares what it looks like under the hood.

The basic eforce will not even make 500whp (which is your goal I believe) unless you upgrade the pulley and add a fuel pump which adds additional costs of parts and time/labor. At that point you might as well go to a turbo system...which is what I'm currently running.
The eforce warranty is only valid if you upload/run the canned tune that comes with the kit.
Which is a part of the reason for the lack of hp. Spend some time reading threads in the "forced induction" part of this forum. There is some really good info available.

I vote SC.Fast,relatively easy install with proven technology and instantly gain around 120 HP.Many,many units to choose from too.From neatly tucked in PRO CHARGER to a sticking out the hood big old blower.Not a lot of engine mods needed with it either. Why bother "nickel and diming" yourself to death?Cut to the chase and start enjoying all that power.I happen to like the EDELBROCK look,btw.

I'd vote SC. Mild when wanted. Wild when needed.
I'd look at Vortech. It's a centrifugal SC. think turbo hooked to a pulley. They are making some great power on the LS3s and are incredibly efficient. Not as pretty as an Eaton though.

I have a stone stock 08 A6 with the NPP exhaust........and an A&A centrifugal supercharger. I produces 580 rwhp at 6500 rpm.
In street and freeway driving, operating the gas pedal just to move in the normal traffic flow, my engine rarely, and then only briefly, goes above 2000 rpm. At 70 mph, I'm turning 1700 rpm. Below 2000 rpm, the supercharger just doesn't do anything, expecially since the blow-off valve is open. So with this supercharger, the car drives just like a stock A6 in normal daily driving. The supercharger is very quiet at street/freeway speeds so you don't know it's there until you start to push the gas pedal down.
At 2500 rpm, you can sense the car has a little more power, at 3000 rpm, you definately feel the supercharger coming on. From 3000 rpm to 6500 rpm, engine hp is sort of a straight line upward. The roots blowers start to plateau at about 4000 rpm (?)...or so I've been told. The centri just pumps out more and more power until the engine control computer over-rev safeguard shuts the engine down. At 6500 rpm, the centrifugal blower turbine is turning 48,750 rpm!
The A&A install includes a pretty large air/air intercooler. It fits completely behind the front grill opening. You can't see it unless you get down and look into the grill opening.

also question: is the E-Force the only SC that offers a warranty?

Anybody do an A&A kit on an LS2? Any differences worth mentioning compared to an LS3?
Hey what does your SC itself sound like? I definitely want to hear my unit when it kicks in.

It's a brand new car. Mod anything you want out of warranty, but bolw the bottom end out of a '12, or destroy the A6, and who's paying for it? You are.
I never said the E-Force was the cheapest or the best, but it is the only one that covers the drivetrain with the stock tune for 5yrs /100K mi.
I've the 1591 kit, with the 600hp kit, and fuel pump. Its plenty more than anyone here needs on the street period!

I have a '12 GS and thought about the Edelbrock supercharger, my main concern was voiding the warranty which is unacceptable to me, even for those that say if anything happens you can turn it back to stock....if you have previously been bringing it in to the dealer for scheduled service and they see the supercharger they will void the warranty at that time, just not worth it to me.
However, after warranty, that's another story!
During the warranty period a Callaway mod would be the only one that GM would allow
