A search will review a few post on this subject.
To answer-no.
They had a unit for the earlier 4.7's but pulled it shortly afterwards.

 

No TRD Supercharger for 05 and up. They changed the head and added the VVTI which was not a good combo with the existing supercharger. If you had an 03-04 you could track down the TRD s/c and go nuts...this would get you about 271 HP and 320ft/lbs torque( with CAI and exhaust).

That being said that does not mean that there are not other brand s/c's out there, try searching toyota forums for brand names...but they will all void your warranty.
