3.3l engine noise

I have a 2005 grand caravan 3.3l. when driving it seems to have a slight rattle in the engine, once we hit around 43mph it turns to a slight whistle or similar to a high pitched frequency sound. the faster we drive the more profound it gets. It only does this while giving it gas. I brought it back to the dealer (still under warranty) they say it is just normal drivetrain noise. I find this hard to believe. we love the van but this sound is too annoying.

Why not get a second opinion?

My 2003 T&C, with the 3.3l, had an alternator that started to make noise last year when it had about 40000 miles. I don't remember the exact noise, but I used a 'mechanics ear' to locate it to the alternator. I think the noise was probably coming from the pulley damper that is attached to the alternator pulley. I went ahead and replaced the alternator, which came with the pulley and damper, and the noise went away.
