Ok well i thought it was the turbo but now im kinda second guessing myself... does anybody know what makes some truck have a really high pitch whisle, not all of them do it but iv heard a couple... if a certin mod could you explain it to me? thanks.

Do you have a general idea of a location of where its coming from..??

 

[nailt29]

well its from the engine and i think on the drivers side.. i heard one powerstroke do it yesterday and only a hand full of dmaxs.. but haha it sounds badass.

Try checking the intercooler boots and are if there is any holes or cuts on them

 

[Hondarider552]

well your lb7 is a fixed turbo so it doesnt have any turbo vains that create the whistle.

Right, 6.0 PS's and 04.5 and up dmaxs have the VNT turbos, whistl;e is much more noticeable on them!!

Mine whistles pretty good for a stock IHI

to make the IHI whistle louder youll want to have a ported intake horn which i can get you. it makes a huge difference and it spools a few 100 RPM's faster. i also will have a compressor wheel upgrade availible soon after they ge tested alittle which will help spoolup, whistle, and flow more air and high PSI
