noisy truck
 

It’s a 96 7.3 f250 1 ton, I hear the engine ok but next to other truck same kind of year or at least body type it seems way to noisy it has a strait 3 in pipe no silencer and a intake the cheap one the “napa” any help on diagnostics or enlightening me thanks
:humm:

Non -factory intakes are much louder.

the noise its not the turbo whistle im referring to its the engine noise that distinguish diesel engines its louder

I was not referring to turbo whistle.

a faulty icp or ipr can do this and the computer strategy can make a difference

sorry but could you explain whats the "ICP" or "IPR"
and what do you mean by computer strategy changing it or what
thanks

ICP is injection control pressure

IPR Is injection pressure regulator

Is the truck auto or stick?

its an automatic 1 ton i now its a 1 ton cause i had to change the front 4x4 bar from the dig to the hub and it was thiker than the 3/4, and th noise its not the turbo i like that its the cladsic diesel sound its louder than in other trucks

It is the intake.
The second I replaced the stock intake, with your same intake, and did nothing else, it got LOUDER!
it got louder in the cab, it got louder outside the cab, it got louder under the truck, it got louder over the truck, it got louder if you stood on your head. IT IS THE INTAKE!

He's talking about the "Crack" from the HEUI injection. Not intake noise.

that "crack" noise comes out louder through a modded intake. I know exactly what he's talking about, I have heard the difference pre and post intake mod. I can go listen to them right now because I have two OBS Powerstrokes, one with the mod, one stock... It's the engine noise (including the "injector crack") coming out even louder through the intake. The intake itself makes no noise, but it does funnel it out. How do you think a simple (non-electric) cheerleader's megaphone works? Go start a stock truck, then remove the filter cover and hear how much engine noise comes out there! The stock intake has excellent noise suppression and no-doubt, was designed that way.

...IT IS THE INTAKE!

I noticed no difference in swapping my intakes. at all.

I asked this question before on here. I have heard some that are loud and some are a little more quiet. I have been curious to what the cause is but never really found out. I thought it was my injectors that made it louder but I put new ones in and same noise and everything is fine.

so theres no solutin just enjoy the noise :rocking:

or is there ???????????:humm:

o and the noise was kind of the same (loud) whit the stock intake

Each truck is different there is loud ones and quiet ones I really don't kno if there is a solution as long as everything is working properly I wouldn't worry to much about it and just smile when your neighbors come out telling you to shut off that loud ass diesel:tu:
