I have a 2002 spyder, Every time I drive it I hear a whistling at around 3300 and up RPMs... Only while It's driving it doesn't happen in park or neutral, Noise is coming under the hood from somewhere.

It isn't my car, It's my aunts I'm not sure all the specs on it. So if you need more information ask and I'll post it.

 

check the plastic air intake than runs out of the air filter box to just over the radiator, the two plastic retaining clips will come loose and it will suck up against the hood and whistle on a hard throttle.
