Cam help
what size cam would you guys recommend? I am not well trained on internals.
Talking about an '06 vert A6.
I plan to add cam once I have LT's, X-pipe, Corsa and Vram. Its a DD, but want 550+ hp at some point. Well aware that I wont be near there with just these mods alone. I want strong powerband down low and mid, off the line for street use. And may be adding a centri SC later, with top end power band.

You will not get to 550 without horrible drivability or adding a supercharger. Check out my signature for the cam i did, and I am nowhere near 500. I did keep the street drivability, though.

You could check out a Thunder Racing TruTorq lvl 2 cam
Good, mild cam and would be well suited for a blower later on and will work with your current setup nicely (which doesn't include a torque converter)
Slightly negative overlap will make it easier to tune on the auto trans.
"TR TRuTorq" Level 2 - 223/230 .609/.604 115 LSA
With a Ported FAST you should make in the 435rwhp range and set you up nicely for a centrifugal blower to take you over 550rwhp

no i know, thats what i meant after adding the centri. and what part of driveability are you referring to? I dont mind losing in that area so much

also, I want that choppy idle, so what type of overlap do I need to achieve that?

Auto LS2s don't put up big numbers on the dyno.
0-4 degrees overlap in your cam will get a choppy idle and still be fairly easy to tune in the auto transmission.
A Texas Speed 224/228 112lsa cam would also work well with a stock converter and have a little more overlap than the Tru Torq 2.

Since nobody clarified, Italiano, is your 550+ requirement a wheel horsepower measurement or flywheel? If that's flywheel, then you can just about get there with a healthy cam similar to what Toxic C6 posted and that ported Fast 92. However, with that auto you're going to need to pony up for a higher stall converter as mentioned. If that 550+ is a wheel measurement, well, good luck. You're looking at a rather huge cam with associated flycutting, TFS 225's at least, a little more compression, and potentially some meth. Through an auto, that might still come up short without going larger displacement. The cheapest and easiest way to make that 550+ to the wheels is just to drop the $6-7k up front and go centrifugal.

No....he would definitely not be hitting 550 flywheel horsepower with a cam-only auto LS2.

Not even flywheel HP. An LS2 auto will lose 20% from the flywheel. this means that a bone stock LS2 will dyno anywhere from 320 - 360 depending on certain factors, including how the dyno is itself.
With all my mods, I am still at 410 RWHP. Granted, the loss from the 3200 torque converter could be factored in, but even so, there is no way a cam only will get him anywhere near 550 on an LS2, flywheel or RWHP.
And who cares about flywheel HP anyhow????

LS3 is a different beast than the LS2 in the hp game. You can knock off about 30-50 rwhp right off the top from an LS3 to put you in the ballpark on an LS2 with the exact same mod setup. On my 08 A6, I've got a pretty beastly cam, heads, headers, exhaust, stall, and managed 493 hp to the wheels. Street manners are still fine, but any type of larger cam for me and that would have went right out the door and I still wouldn't have managed 550 rwhp unless I went forced induction too.

I went with a 224/230 cam with a 114 LSA custom grind from Texas speed. With that and LG street headers I dyno'd at 465HP/471TQ here is the link to my exhaust vid
