LS6 intake worth it?

if you're not doing any other mods I would say no, its not needed. I had the LS1 intake !air and switched to the LS6 intake and didnt notice anything, bolt-on A4. The LS6 intake isnt going to hurt at all, I just wouldn't expect much gain.

Current mods are in my sig. Honestly, don't see any other mods in the future...at least not for this car (except maybe a tune). Stock cam is staying in, as there's no $$ for another. I'm after a little more hp and tq, but this car will never see the track, and top end (over 6k rpm) is out of the question. So, would a LS6 intake be worth it for ME?
Nope not worth it for you. You'll gain more from a tune than you will from the ls6 intake.

But hell gain more from his tune with an ls6 intake, its not an either or situation it makes sense to get the intake and then tune so you dont have to redo it later if you change your mind. it sound like you want to get all you can as cheaply as you can without going internal. i would do the intake and a tune and it sounds like your done...

Probably true. Although I had headers, catback, lid, cam and tune, then afterwards decided to do ls6 manifold and saw no gain. Granted it was on two different dynos, but the first one was a mustang, the second a dynajet.
And like someone mentioned previously, has a larger plenum, which makes gain only in high rpm...
I'm not saying it's a bad mod, just not sure it's everything everyone on here has it cracked up to be.

Another argument demonstrating that dyno's are for tuning & not for proving or diss-proving single modifications.

1)Valves are closed. There is no PTV clearance issue.
2)Maybe, depends on what you buy.
3)Yes, as noted originally
4)I tune on the street w/ EFI live. Further, a dyno would prove nothing. Too many Dyno variables involved when trying to measure a single mod like rockers. I could do nothing to my car & pick up 8 to 9 HP on a different day on the same dyno.
Yes, the airflow increased after adding 1.8's to my mild cam. I can log airflow w/ EFI Live. IMO, 1.8 rockers are a good way to to help small cams when the owner doesn't want the hassle of doing a swap "for small or stock cams ONLY." The rockers don't have to cost $500 either.
I stand by my statement that an LS6 intake & properly installed 1.8 rockers will wake your car up w/ less hassle than a cam swap.

How much power will a RR and ls6 wake a car up?

Can't answer that. It depends on too many variables. I can say that it will increase power. Increased &/or less restricted airflow + greater valve lift = more air entering the combustion chamber. After tuning for the air increase, power is increased.
Here is an example of some mods & how my car benefitted: (As noted earlier, I can log airflow).
After adding a Weiand intake, heads, mild cam, 1.8 rockers, & 85mm TB my car moved 27% more air than when it had stock intake, cam, rockers, TB, long tubes, & true duals.
After then shortening the length of the cold air intake & adding an 85mm MAF, gained another 3% of airflow.

When I installed mine, I definately noticed a seat of the pants difference. 
I carried it out a day before I did the swap and a day afterwards. When it got to about 3500 rpm I could feel it pulling harder, and it did better all the way to the redline. Down low I actually felt a little bit of a loss, but that is to be expected with the larger runners/volume of the intake. Its definately cheaper than a fast setup. I couldn't justify spendng 900 on a intake and another 300 on a tb.

I would definately hold off and save your money for a fast setup, You maybe happy with your ls6 intake at first, But if your like me then you always want bigger and better. Save and go with the fast
