    I just put in my 65mm accufab,and it whistles!!! The only reason I went with this brand is because everyone on this site said it was the best and didnt whistle!! Other wise it runs great,but,,,,,aahhhh,,,,,,,,Owell !!

    That sucks, mine doesn't. Maby you should contact who you bought it from or Accufab itself. They might swap out for you. Don't confuse the air sucking sound and a wistle.

    Ford is the only throttlebody that I KNOW dosent whistle, accufab was the next best.

    I have a ford throttle body, over the cam, roller rockers, blower, and fans, I dont know if it whistles or not, but I dont think it does.

    That's exactly why I got the Accufab too. I have the 70mm and it does not whistle at all. Plus I put the Moroso CAI on. And after that it does have a high pitched air whine but only at WOT.normal cruise is no problem. But how long can you stay at normal cruise anyway? :)

    Guess I've been lucky, BBK 70mm with no whistle and BBK 75mm with no whistle. If it is whistling at idle try adjusting your throttle blade screw slightly.

    I've got a 70mm Edlebrock, if it whistles than maybe I just don't know what to listen for. I've never heard a whistle coming from under the hood. Had a 65mm Cobra TB before, didn't notice any new sounds when I switched to this one :shrug:
    If I listen real carefully in the summer with the windows down though, I can hear the air sucking into the ram vents in my hood when I take off easy :flame:

    It does it at half throttle,its very noticable.Im sure if you were standing outside you could hear it.It doesnt seem to be hurting anything,but it makes it sound cheap!!
