Who Has A 75mm Throttle Body That Dosnt Whistle?!

[MY 85 GT]

The funny thing is Mine never whistled until i had a surging problem and re-adjusted a few things...i think my idle is higher now so that might contribute to the Whistle...

 

[cleanLX]

whats your idle at if you dont mind me asking?,mines goes away when i drop idle real low...thanks

1200ish.

 

[MY 85 GT]

1200ish.

Thats a little High NO?...why do you have it set so high mine is like 850-900...

 

[cleanLX]

.680 lift solid roller, 140cc heads, 7500rpm shift point... that's where it likes it.

 

[MY 85 GT]

Then i wonder if thats why it is whistling? high rpm.

 

[cleanLX]

Not sure I understand? My Accufab does not whistle.

 

[MY 85 GT]

It was for the original Poster he said if he lowers it the whistle goes away I said maybe his idle is to high...I notice mine did it after I re-adjusted my idle after surging issues...

Sure it not the turbo whistle? Lol

 

[MY 85 GT]

LOL....I wish the turbo is pretty quiet actually you will hear it when in high boost but normal driving you don't hear anything but my LOUD bbk TB....lol

i went from a whistling 65mm bbk, to a 70mm accufab that makes a very loud swooshing sound when you stab it. but no one is asking if i have a turbo anymore, lol.

I had a 65mm that always whistled. I have a 75mm now and it whistles too. I always thought that was just the nature of the larger TB's. I've just learned to live with it.

My Accufab whistles. It is really annoying.

Whaaaaaa????

 

[LarsD]

Whaaaaaa????

Yup, 75mm iirc. Whistles all day long. Has since new.

76mm Professional Products whistles at idle above 650......................

The Accufabs sure look nice, but I'm not sure that mechanically they are really any better built than the BBKs, et al. The Accufab IAC ports are just machined differently (at least my 90mm unit's are), which I think helps mitigate the whistle.

No whistle coming from my Accufab at all
