I remember a thread like this and I think someone said they drilled a small hole in the throttle blade......I don't know if that was what they did but it was something like that

I think Roland is thinking of a slightly different issue - it's often the small hole that causes whistling.

Does the Throttleblade have a hole in it already?

I heard Mac's tbs's do this too. I bought one (mac) off a guy for $20 and haven't put it on yet. Don't know if I should even bother. The guy I bought it from said it was whistling where the throttle blade rod meets the top or bottom of the tb.

Good luck

My BBK 70 whistled like a mofo..my PP 65 whistles sometimes and my buddies mac 70 carries a nice tune as well.

mine whistles too. you get used to it. i tell people it is a supercharger!

 

[gruvee87vertgt]

the whistle is caused by your intake manifold air inlet. since the intake inlet is different from the outlet of you tb, the air being pushd thru goes thru a obsticle curse which causes the whine/whistle

you need to port match you intake inlet to stop the whislte.

My original BBK throttle body whistled up until the throttle blade shaft broke. This was a few years ago and I'm not sure how old the unit was. BBK replaced the entire unit with a different casting that didn't whistle. Call them they may swap it out for you or offer a suggestion on getting rid of the whistle. I believe the whistle actually comes from the edges of the bypass bores.

WRONG AND COMPLETELY INCORRECT!

SOme just do this bro, it is really no big deal. I have an Accufab 70mm with port matched intake and it does whistle a little under load at times.

I have a accu fab tb with a cobra intake. I port matched the intake myself untill the whistle went away. Therefore I am speaking facts not fiction or belief.

After my CAI it whistled a lot less. BBKs are know for that noise. Especially if you are on it and shifting.

Found a sticky on another site about this issue... don't have one myself but i thought i would pass this along. They solved it by just anding the rough edges inside the throttle body.

There is a screw on the backside of the throttle, its called a throttle plate hard stop screw. Turn it one way or another until it goes away.
