hey guys , can someone come up with a way to make the old IDI 7.3's stop sounding like a gaser? at idle they sound like a stroke, but when in high RPM's, they sound like they have a 351! anyone got any tip or mechanics you can do to make her sound as close to a stroke as possible??
It's the nature of the beast with an indirect injected engine - they're quieter than direct injection.

i dont want it noisier, just dont want that old 351 sound, i want a POWERSTROKE sound, but i mean front the front of the truck when u revb it up it sounds normaly like a stroke, but quiter. But when u move to the side or back it just sounds like nowhere near a diesel, so no one has any ideas about changing around exhaust or sumthin?? or anything??

I wonder if ftermarket headers (if available) to a custom x-pipe to aftermarket muffler really might smooth of the sound and make it less poppy... This was the case on my 302 stang, which is a different beast, but I'm curious if it would work by any chance. Ideas?

Only chip would be the ones on the seat smothered with nacho sauce. My truck sounds like a diesel through the entire RPM range. May be my age but I used to run a 460 with headman headers and dual 2 1/2' out the back. It would set off car alarms @ 1500 RPM...I like running as close to stealth as possible now...the radio sounds better and the speakers will probably not need replacing.

to much money, to much time, idk if i put stacks will that help?? or maybe chip it, cold air kit, idk maybe even injectors....$$
as far as answering your question, i think my idea is a decent one... And of course it would cost money to do. You even asked if you could do something with the exhaust and I think i hit it pretty close. Stacks won't help... That's just moving the sound you hate so much into the bed. Air intake? that won't do a think to change the sound... Can't chIp the IDI, and injectors just give the engine fuel, it won't change the way it sounds at all. That's like saying a fuel pump will change the sound at all... Not gonna happen. You have to mess with exhaust gasses, ie turbo, x-pipe, mufflers, headers, etc.

Its an IDI not a DI (powerstroke) Thats just what its going to sound like. The most advanced piece of electric technology under that hood its probably the alternator hence the beauty of these engines cause there's not much to go wrong. Sure you can make it sound like a powerstroke but you're going to need to be running over 20psi of boost like the powerstrokes do. Doing that isn't easily reliably accomplished without adding a turbo setup capable of over 20 psi of boost, fire-ringing the heads, widening the pre-chambers, getting bigger injectors and a larger IP like a Moose pump or something, and then keeping it cool by adding an intercooler, and larger exhaust and in conclusion it would be cheaper to buy something like a low milage 2007 Powerstroke than making this engine perform up there and "sound" like a powerstroke. Then again, its a truck, they tow, haul, and do work. Ford didn't really put "sound" on the drawing board This engine will however outlast it's truck's body and short of basic maintenance, run and run and run and...

An IDI will never sound like a powerstroke ever. If you want a loud diesel, put an older 12 valve cummins under the hood. They are not computer controlled, and you get a turbo. They are non computer controlled like the engine you have also. These conversions are getting more common these days, and I am sure there is a fair amount of info out there to get the job done. Only reason I don't say put a powerstroke is you stay computer-less with the cummins, and you get all the racket you want. Me personally, I like the fact my IDI is nice and quiet on the highway, but I guess that comes with age, at least it did for me.

Well besides that, i have a bigger garrett turbo, and the guy i bought the truck from said that you can turn that turbo up somehow?? so can anyone explain how to do this?? o and is it okay if i turn the injector/fuel pump up a little bit?
I dunno, I really like the sound of the IDI diesel. At idle it has that classic diesel growl and at full throttle it sounds like a badass big block American V8. Correct me if I'm wrong but I'd imagine that a new exhaust system and a chip would make that sound even more prominent.

Your wrong about the chip...Doesn't make a bit of difference. I have a turbo and 3" unrestricted exhaust. It doesn't sound ANY thing like my old '86 with it's 460, Headman headers and dual 2 1/2 unrestricted exhaust.
I like the way my truck sounds and the exhaust level was fine for hours at a time this summer on our road trip. In 2000 I took the gasser to Missouri and back and after 4 hrs. my ears were ringing.
