TB whistle, see ya.

Well I ordered a 62mm throttle body and was talking to the guy about the dreaded whistle with what I have now. He said that the gasket is usually the cause of the problem. So this morning I went out and pulled it apart. Sure enough my gasket had been sticking out into the throttle body by about a 1/16 to1/8 of an inch. Now I do have a Helix spacer on, but that gasket was back far enough to not cause a problem. So after putting everything back together, it was time to test it out. What do you know it actually worked. If I really listen, I can here yet a faint PFFT sound. I do have a K&N intake on it, and you can still here the vacuum sucking sound from that. But the whistle I was getting around 2,300-2,400 RPM is gone.

Here's a pic of where I cut.


Don't know if this will help anyone else out, but it helped out in my case.

cool, i've got a spacer and a 62mm TB waiting to be installed. have you run the 62mm w/o the spacer? does the spacer do anything?

also what gasket do you use? my spacer came with some, but they look crappy. any ideas?

I do not have the 62mm yet(just ordered), I am still running the stock TB with spacer. As far as the spacer doing anything, that is noticable no. But when you look under the hood it looks nice.

I used the gasket that came with the Helix spacer. And the one that I cut was probably still the factory one on the throttle body.

Used the search engine. Once again another 5 year old thread. Anyway, I figured I'd revive this incase anyone had any other ideas in the past few years on what the problem might be. I tried this method on my bored tb with no luck. Same annoying whistle. I've ground down every sharp edge, sealed everything on the tb and no progress. I knew I should have kept everything stock.

Can you even tell that TB makes a difference?

It has very little better throttle response. That's about all they do. Oh, they whistle too. I noticed that I had a little smoother idle too, but I probably would have gotten that if I had cleaned my old one. I found lots of people claiming how great they were so I didn't even bother with my old one, I just got a bored one. Biggest PITA. All it likes to do is whistle. I'm currently looking for a stock one to put back on and melt down the one that's bored out.

That "PFFT" sounds is mostly from the dust bouncing down the intake right after it clears the K&N filter.

On a more serious note, lose the K&N filter or at a minimum, put one or more pre-filters on it to keep the dust/dirt out of your engine.
