Default Help track down a strange noise.
After the FM13 install I noticed a strange whistling that increased with RPM's. I thought it was the belts and replaced them. Switched out alternators, checked all pulleys and tensioners. Still the same annoying whistle. Upon closer inspection it seems to be coming from the intake. I changed out bellows just to check with no change. Could the extra air the FM13 is sucking in over the TR224 maybe cause a whistle in the intake runners? Checked all vacuum lines and nothing was swapped other then the cam. This is really annoying and any help is appreciated!

John

Maybe an exhaust leak from deleting EGR?

You ever get this narrowed down John? I have the same thing going on after a head and cam swap. So my intake actually came off, which is interesting since yours did not. My thread is "Hissing/Whistling sound after H/C".

I've even swapped to a LSX 90 setup and it's still there. Has to be something with the Futral cams. A friend of mine just put on a FM11 and it does the same thing. Several guys on here with Futral cams has the same whistle. I gave up!

Did this ever get figured out? I just installed an F13 last night from a TR224, and now I have the same whistle. Sounds like a small turbo.

No. But by playing with the throttle just right, I have got it to whistle "Dixie."

Whistling = the price you pay for power, lol.

How bad is it? If it's happening to everyone then it must not be a major issue. Anyone contacted FMS to inquire?
