How long does it take to carbonate a 5gal cornelius keg of beer?

Greetings All,
I am a novice brewer on my 3rd batch.
Got creative and converted my kegarator to accept Cornelius kegs as well as commercial kegs.
I kegged my double hop IPA (a first) about a week ago.
I have had about 11 lbs of pressure on the 5 gal keg.
It pours nicely and tastes great but it has not picked up any carbonation yet.
How long should it take for the brew to pick up the C02?
Should have I went through the secondary fermentation to pick up the C02?
Seem like it should have picked up quite a bit of carbonation on a weeks time.

Any advise is appreciated!
Thanks!

It can take a while to carbonate a keg with just head pressure (i.e. hooking the CO2 line up to the gas in fitting) unless you also provide some agitation to aid absorption.  Most methods I'm familiar with suggest hooking the CO2 tank up to the liquid out fitting so CO2 bubbles up through the beer.  One can then either set the regulator to the desired carbonation level (for the temp the beer is at) and wait a week or so; or for the impatient method, jack up the pressure to 30psi, shake the keg several minutes, rest, and repeat to speed up carbonation before bleeding out the excess CO2 to the desired pressure.

Thirsty_Monk:
It takes about 3 weeks to carbonate 5 gal keg under dispensing pressure.

CO2 absorption in beer is dependent on Temp and pressure:

Thanks for the input all!
Guess I was just a little impatient.
The keg is so much easier then bottling!

I'm a keg newbie also, would this method affect head retention?
