Does your 308 Whistle?

carbs - THANK YOU HANS!!!!!

 

QV owner here and yes, mine whistles ever so slightly.

 

Yes - my QV does.

I installed a Quicksilver exhaust - now I barely hear it.

 

The only thing that whistles are all the girls as I go driving by them.

 

If you have the stock exhaust, its the tips causing it. It can be fixed by rolling some stainless steel and inserting into the tips.

 

Yes, my 308 GTSi does too! Pretty Cool!

Yes and mine is a 1983 308QV

 

My 83 QV had a VW bug exhaust whistle when I first got it. I fixed it completely and simply with a bit of rolled stainless steel sheet metal.

See this thread:

There are other sources of whistle however.

 

Could also be caused by the air injection tubes in the head

 

A lot of different answers on this one. I guess it depends upon the whistle.

My '79 Carb (it also has the older more aggressive cams like a Dino) does along with other sweet noises.

 

My '83 QV also. Nothing wrong with the car and I think it sounds cool.

 

Pretty sure if Ferrari wanted it to whistle they would have installed one.

 

My '84 GTS Qv also whistles......my mechanic says it comes from the very loud Bell Sports exhaust system that was fitted in the UK (the car was imported from the UK to Australia)........because the exhaust is so loud, the whistle is pretty loud too but it only happens between 3000-4500rpm.

I was told that a K&N air filter will cause the whistle. Mine started right after installed one.

 

very slight whistle here. 2V injected. Could be the K&N or I thought I heard once that the K-jet sometimes generates a whistling sound.

 

I thought my car had some issues hearing the whistle (screech at high RPM's).
Glad to know it may be a welcome and normal sound!

 

Yes this is what I think it is, I removed the air injection tubes, installed plugs and have no whistle.

 

The whistle is not annoying to me, I kinda like it. It's the chirp that's bugs me. I'm either going to do the stainless steel thing or epoxy the holes in the exhaust tips.

 

Mine whistles. '79 Euro with Stainless Borla Exhaust.

 

Mine doesn't.

 

I have read that the frequency valve makes the chirping sound but at my age I don't hear it.
