I guess that brings me to the only thing I would add here. Determine what it is you want and have a plan for getting there. You should be able to get rides in cars with various setups at gtg's. Research on line will help you develop a short list but there is no substitute for actual seat time which is worth a thousand words. Once you know what you want then it comes down to good planning. Your plan should include upgrading anything thats going to break at your new power level. Its cheaper to fix it up front then after the fact. A lesson I have learned the hard way. Might want to think about how your going to get that new found power to the ground as well. Happy hunting.

I don't know about that. I have been in a sts and aps car and the lag for both was minimal and essentially equal as near as I could tell from my assometer. This isnt to say that I like the sts design, I don't, and could add to powerlabs list of flaws. In fairness however the fellow was discussing lag specifically, not the other issues that come with rear mounting.

the car has a medioker street tune. I checked it and have no knock and air fuel is good...but the lag is (very very) bad. full boost is 4500-5000rpm and takes 3 seconds to get going. I am going to try the 36 ar housings....but was told i will lose 50rwhp off the top.

Im not complaining...just trying see if there is something wrong...with all you alls help. Im comparing/referencing the 87 Buick Turbo (stock turbo with ported housings) chip and exhaust that went 12.18@110 and the 89 Pontiac Turbo Trans Am Pace Car that went high 12s with a chip and airbox..that I had for years. I never said this lag sucks...Its good for getting out of the hole..
You guys dont want to know what this STS C5 Twin Turbo ran at the track last weekend..its too embarrassing to even post...

Dan,
People are going to come here, and they are going to tell you that whatever happens to be in their car is the best. Then a shop or two is going to show up and post that their kit is the best, and they might say a thing or two about why. Then maybe someone will disagree and a pissing match will start; finally the thread will fizzle out or the pissing match will get interesting and it will be blocked.

This is so true. LOL.
As for supercharger systems I vote for the Procharger setups. We have made plenty of power with their setups and have done so reliably. A few weeks ago we had a customer doing back to back 9.2X runs, all record breaking quarter mile passes without a hick-up in the SC setup. You really have to look into what fits your needs and desires.
Maybe a turbo setup maybe more what you are looking for.
As for rear mount turbo setups, we have plenty of experience with them. Yesterday we had a customer drive to the track, air his drag radials down, click off and 9.08@155 hot lapped it around and then blasted off a 8.87@155... aired up the tires and went home with his 3700+ pound C5 street car. Does this mean this is the setup for you... nope. It's all about what best fits your needs.
APS and TTI have excellent kits, with front mount turbos you have lots of great potential, but there is lots to consider with them as well.
Give us a call, we can go through all the pros and cons of each setup and figure out what is best for you.

Here is my 2 cents everyone.
I have put a lot of supercharger systems on Corvettes over many years as well as turbo systems. If you want my opinon the best and most reliable is the Magnuson system that Callaway is now selling. You have max power from the low to high powerband.
You will need to replace the hood but I am getting over 592 RWHP warm engine on 2008 LS3 Corvettes with headers, pulley change and mufflers nothing else. Really looks impressive when the hood is opened.
Now you want a under the hood system A&A's is the best in my opinion. Fits perfect and very reliable. You will have power like a turbo system low mid range to high. Andy's quality is unmatched by any other under the hood systems.
These are the only 2 supercharger systems I do for Corvette and have never had a problem with either of them.

Magnusen Savings Fund
Several years ago I rode in a friends' car (not a Vette) who installed a turbo system. Of course he was happy with it, but I silently kept asking myself, "...ok, so when does the power kick in?" Finally, when he had the engine up to about 4,000 RPM it seemed to "kick in" as we puttered around. Afterwards, I thought to myself, "....oh god, horrible lag, hmmm, this isn't for me."
Years later, I rode in another car with the ProCharger. No lag, but no low rpm "head-snap" either, he had to wind it up before I really noticed anything, felt good at high rpm, though.
I haven't ridden in a car with a Magnuson, yet, but I've talked with many that have them. Every response is immediate head-snapping power at any rpm, so I've created my own Magnuson Savings Fund! I've already got the hood, so I'm ready!

100%m except that you are making a LOT more than most maggie guys are... Low 500s seems much more common with a couple cars hitting mid 500s... You must have a very nicely set up and tuned system. Or a very optimistic dyno 
There was a very good thread on FI discussing positive displacement vs centrifugal superchargers; I did a comparison calculating how much torque a car would put to the ground in each gear from a hypothetical 60MPH roll on; the roots car in my example, despite making considerably less (30some) power and torque, was quicker in all gears except 2nd... I think it makes a good point for those looking for good day to day performance at typical daily driving RPMs instead of a dedicated drag racing setup that has to be shifted near redline before all the power can be extracted from it.
The thread is here: http://forums.corvetteforum.com/c6-forced-induction-nitrous/2189237-twinscrew-vrs-centrifigual.html
My comparison is on post #4.
