No, you weren't. The question was answered about 3 times before, by Scawen and by others though.
EDIT: To add something constructive to this post, I think that the sound needs to be louder on lift off, ie. say you're going at 5500rpm and you lift. The sound should be different to the sound you get when you lift at 7000rpm and you allow revs to drop to 5500. I'd like to hear the engine choking on itself as its no longer feeding on the squirrels and kittens in the (squirrel? ) tank, and the remaining bones in the pistons being shattered to pieces. Ok, that last sentence was overdoing the violence thing but you get the point .
EDIT2: I think the LX4 should sound somewhat like this, albeit a bit less meaty (as the car in the video has some 70hp more): http://youtube.com/watch?v=TE2bPmNokFU
