Hey guys, I have always liked the way that diesels have sounded with that high pitched noise occurring as the RPM's go up. Is there anyway I can make a mod to the engine in order to get that high pitched sound so when I'm driving? I have a Spectre air filter on right now and when I have a cold start up I do get a pitched noise for about 5 or 6 seconds and then it goes away. Is there anything I can do to get this high pitched sound whenever I press on the pedal? (No, I don't want to buy a diesel haha)

Thanks

 

You talking about the turbo whine? You need a turbo then.

 

Yeah I think so, it's that high pitched noise that you hear from diesels as the driver presses on the gas pedal and the RPM's go up. If that is what I need, where would be a good place to look and are their certain brands to look for?

 

I think you can put an STS turbo on a 4.7

 

as far as my knowledge, noone makes turbo for our 4.7s, trust me, i would have it. i love turbo. my grandpas 300z has it and that thing moves. It would add around 100 hp if you have it tuned right. i think i recall someone in the process of making a turbo for 4.7s but i could be wrong. We're just gonna have to wait lol. o, and they cost around 4,000 big ones.

 

Superchargers are available though. You could custom fit a turbo but it's all a matter of how much you want to spend.

 

there used to be a bolt on turbo for 4.7s, but they got discontinued for some reason.

 

Yeah, I don't have a huge budget right now but what kind of performance would it give the truck, how much hp? And would it also give it that high pitched sound?

 

Yeah probably when the HEMI came out

 

I believe a turbo or supercharger are worth up to 50% more power. It depends on the amount of boost. They both make a whining sound though.
