Vortech concerns.
Vortech V-2 SQ S-Trim Supercharger
The new generation supercharger included in most Vortech street supercharging systems
* Helical cut gear profile with SQ technology
* Near silent operation
* Fits engines up to 680 horsepower
* Maximum airflow: 1,000 CFM *
* Maximum boost pressure: 20 PSI *
* Maximum impeller speed: 50,000 RPM
* Adiabatic efficiency: 72% **
* Available with straight or curved discharge and clockwise or counterclockwise rotation

Does this mean that the supercharger will only be able to handle boost until the engine reaches 680 HP?
Sorry im not really good with this!Also how loud/quite is the SQ system, is there anything you could modify in the system to get the "fluttering" sound you usually hear from a turbo-charged car? not the BOV "woosh".

The super quiet (SQ) Vortech I had on another vehicle was quiet as far as blower sound, but it made an ungodly rattling sound. I pulled the head unit and sent back for repairs. Put it back on...same thing, so I got rid of it. The airflow you have listed is will definitely restrict power output.

thx for the reply, I read this somewhere, is this common?
yeah it sure does restrict output, but does this mean the blower will only be able to run on a car below or equal to 680 HP? that's weird =S

The Vortech V2 SQ head units are among, if not THE quietest head unit on the market. They do make other models like the V1 which are somewhat noisy, like some others on the market. I have the V2 SQ S-Trim on my car and not only is it quiet, it has produced 668 horsepower at the wheels with a very conservative tune at 9.4psi, 14* of timing, 11.4 A/F ratio(build specs in my sig). When you factor in drivetrain loss of about 12%, that gives me 750+ flywheel horsepower. Andy at A&A Corvette is the best source for Vortech Supercharger kits and application advice. Good luck with your mods whichever unit you choose. There's nothing like the "rush of acceleration" from Forced Induction

Don't worry the Z06 kit uses the T-trim head unit so you should be fine for HP. Your limitation is the stock fuel system on the C6Z06.
I'm loving my Vortech kit. Any more power an only 3 and 4th would be useful. Right now the road surface has to be good for 2nd to even hold(and that's rolling onto the throttle carefully).
Enjoy!!!

Don't worry about the noise - I notice it, but that's because I'm listening for it. One corvette enthusiast noticed the noise, but that's just because he had one also and our belt was squeaking a little bit - an issue that has long since been resolved.
At idle it is just about impossible to tell - just a little bit of whine. The noise from the Vortech is almost unnoticeable with the windows up, but is audible with windows down when accelerating at moderate speeds.
btw... I'm tired and I'm not sure if that made any sense

Also how loud/quite is the SQ system, is there anything you could modify in the system to get the "fluttering" sound you usually hear from a turbo-charged car? not the BOV "woosh".

At very low end, not much different than stock. Great to be able to cruise around & pretend to be civil. As your RPMs go up, so does your boost. Instead of having killer boost at low end, waisting rubber and challenging you ability to control your car, you'll experience rapid power gain through redline when you step on it (and I do mean RAPID). If you do not have good traction, you will have trouble controlling the car even with a centrifugal SC.
Having your A6 tranny tuned properly will make all the difference in your experience, though. My low end feels much more potent simply because of my recently improved shifting pattern.
Good luck.... get good tires if you do this!!
The new units are V2 Si and are supposed to be more efficient.

Mine is a LS3 C6, but I'm sure that other than some HP difference your LS2 experience will be similar to mine.
