TB Whistle

Tonight I installed my TFS Plenum and now my TB is whistling. How can I fix this problem?

How bad is the whistle? I get a quick whistle when I first open the throttle body.

That's exactly what mine is doing. How the can I fix it?

Not sure. I think it is normal. I have known several people with my setup and they all have it. Its only when the throttle body first opens...other than that it sounds fine.

Right thats exactly what its doing, there's gotta be a way to fix, What do you think is causing the whistle?

I have no idea. I have checked over and over again for a leak anywhere and there is no leaks. I have checked all my vaccuum lines and nothing. The only explanation I can think of is something internal with the throttle body.

I installed a Dragon plenum and it whistled upon acceleration, especially around 2000 rpms. I contacted Dragon, and they said that this was common for their plenums. It seems that the divider inside the plenum causes the whistling when it splits the air flow. I found the noise to be annoying so I returned the plenum to Dragon. I then ordered an Accufab plenum and haven't had any problems.

You could also try re-positioning your inlet pipes. Move them in/out a little to change the length of the air travel. I even turned my maf a little to change the position of the sensor inside. This finally helped me with my whinning noise.

If you don't like the whistle then you would hate my car. The oval TB and Kenne Bell is very loud.

I dont complain

Smart Move!!!
I've heard a lot of people complain that the TFS and the Dragon elbows whistle. To me, that's just poor engineering / design.
The Accufab doesn't make any weird noises.
