Ok i have a 94 formula lt1 A4 with 188,000 miles on it. Lately when I have been taking it out for drives. When I start to get up in the high rpms...there seems to be a strong whistling sound..not the motor winding out. It only does it when the motor is a little cold. The motor is running pretty good I guess....Although after it has warmed up. From a dead stop If I step on it it will barley squill the tires...but yet It will take of like a bat out of Hell and will shift out of first between 45 and 50mph....does it sound like my motor is not running strong?

 

If you have good tires, an automatic, and 2.73 than your car is probably fine. My car shifts at 55-60mph. Although I can almost spin through all of first, atleast half ways anyways. The whistling sound might be a gas leak on a manifold???

 

Whistling noise when cold sounds like an accessory pully bearing. My alternator does this.

someone installed a turbo while you weren't looking

 

Water pump could possibly be starting to go out. Just a thought.

 

Power steering fluid could be a possibility. Mine does it when its cold out. However that is more of a whine than a whistle. When my altenator was starting to go it would whistle just like a turbo (I would get lots of attention in the tech lanes at the track lol) but it didn't go away once warmed up.
