    Noise in my 99 TA

    There is a strange noise coming from the 1999 TA I bought a few months back. The car has a 402 SLP, Thunder Racing heads, ported and polished throttle body, DTS 12 Bolt and a built 60 trans. The noise is hard to locate and it is a loud whistling noise that is only present when you are pushing the gas. When I let it roll in gear the noise is gone and the when I press the gas itís back. Any suggestions?

    umm try popping your hood and revving it at the throttle body. is your car idleing funny at all? has it been doing it ever since you bought it? might be a leak in your intake somewhere?? do you still have the AIR hooked up? My car wistled real had after I put on my SLP MAF but that was because my intake bellow wasnt seated right and it also whistled when I pulled all my AIR and EGR stuff because I left the AIR pump in at first so the pump was whining pretty loud (sounded supercharged )

    hard to tell with your info but it definatly sounds like its just whistling when it sucks air harder.
