HAMMER DOWN!
Why No Turbo Whistle?
Having a turbo diesel that does not have any turbo whistle is really nagging at me.
As some of you know i recently got a new turbo(new wheels & CHRA), i upgraded my exhaust outlet, got a 3" DP, then 4" from there back with muffler. i am running the factory air box just grabbing nice warm engine bay air.
The ONLY time i can hear any hot side whistle is if i have the radio off, all windows up/closed except for the rear slider. then i still have to be listening for it. i can kind of hear a LITTLE around 1500rpm, but then it is gone right away. There is ZERO whistle at idle. The only cold side whistle i get is when the turbo down spools after an upshift.
I know it is not the muffler killing my whistle b/c i have watched vids of other trucks with the SAME turbo/exhaust set-up, including muffler, and they have a nice, noticeable whistle. the vids i have seen with no muffler and same turbo/exhaust just have a much more defined whistle at all rpm's.
Not really a problem just irritating
Some examples.......
