I have been test driving a few dmax trucks, I am going to buy one before too long. The only thing I don't like is the lack of turbo noise. Will switching to a open air intake make more whistle? I am just wondering, my ford spoils me when it comes to turbo noise



Thanks,


Mike

All I've done is dropped in a K&N filter (stock airbox) and straight-piped the xhaust, the turbo whistles nice and loud now. I may go to an open intake too if it really will make it much louder but I'd like to hear one in person first.. Otherwise I'm happy with how loud it is now.

Couple of options for increased Turbo whistle ....

You could:
1) Open up the front of the airbox below the filter by "swiss cheese " method, bunch of small holes, and drop in a KN. ore AFE, or Amsoil stage II replacement element....
2) Or buy a stage I KN. or AFE setup with an open face element .....
3) Do like I did and buy a stage II Afe setup and I tell you people will look up as you whistle pass .....

I recommend a Nylon wrap on any open face which will filter to 5 um ....

There are others .... Hopefully those with additional experience will add to this thread .....

Mike,


Like you I was very spoiled by the whistel of my dodge. The day I got my dodge I took the baffel out of the turbo so I could hear it. When I got my d max I was sad to find out that there was no baffel to take out. But since I found out that new airbox kits will help Im shopping for those as we speak! I am also getting the banks monster to enhance the whistel.

What is the nylon wrap you are referring too? something that goes over the filter element? Where do you get one? I have seen what your talking about i think on motorcycles, but they were usually to keep water from going in the filters when riding in the rain on bikes without factory airboxs.

Mine definately whistles more since swiss cheesing the airbox and adding the Amsoil two stage air filter.

I recently re-installed the Amsoil filter after running the stock one for a while. Very noticable difference but nowhere near the whistle of a PSD or Cummins.

When shopping for a diesel, how loud the turbo whistled wasn't a buying consideration. I do like hearing it but that's just something you get with the turf.

They are a outer wrap that offers greater filtering cabibilities and sheds water as you suggest ...


Outerwrap is the company I believe that manufactures them ...





I got mine at mrbobsdiscount.com .... I'd give your the hyperlink but I'm at workie .. I'll edit later ...


You can see it in my PICS ...

Thanks a lot for the replies. It is not something that makes a difference when buying a truck to me, but it is a side effect that I enjoy. I did notice on the dmax that the turbo is much louder outside than it is in the cab, must be good insulation. I have the afe on my ford and love it. Thats probably what I'll end up doing.

If turbo whistle is what you want, install an AFE stage II air filter.......

How much does the AFE run?

I paid some where around $230 delivered for the stage two complete kit. Most places sell it for $280 and up. I'll try to find the invoice and post the hyper-link.


It is well worth the money in my opinion.

Check the location of the Mass air sensor ,I say some ,Some trucks had issues with setting a ses code with the KN ..... If the the mass air sensor is to far down strean compared to stock the readings may be skewed to the ECM ....
