Acceleration noise in interior.....
#1

When I give the car some gas, I hear a noise. Kinda like a whine, but not like one you would hear from your radio.
I haven't really looked for where it's coming from or what's causing it yet. I thought I'd ask you guy's to see if any of you have had the same noise.
It doesn't do it at idle or normal driving speeds/RPM's.

What kind of whine is it, where's it coming from? Does it do this when you decelerate quickly? It's a little too general to correctly answer. Could be anything from alternator bearings to diff gears.

It's not the alternator, gears or A/C.
It sounds like its coming from the speakers, but it's NOT an engine whine like what usually comes through the radio.
I doesn't do it when I let off the gas. Only in the high RPM's and during boost.
It's not just the turbo spooling, because my other TC doesn't do it.
I'm thinking it could be a loose engine ground.

Does it do it with the radio OFF? If it's coming from inside the car, it may be coming from the heater core! Don't laugh, Ford published a TSB for some of the cars during this era where they had us puttin' a restrictor in the heater hose to prevent a "moan" from the h/core during acceleration! - try pinchin' off one of the heater hoses with a pair of needle-nose Vise Grips and see if it goes away (probably NOT, but it's worth a shot and, what the hell, it's FREE).
