Quieter Engine

[Hi-psi]

I know this will be the opposite of most of the posts here wanting a louder truck, more turbo whistle, etc, etc.

Shortly after buying my truck 5+ years ago I removed both the hood liner/insulation, as well as the intercooler pipe foil due to both of them being ripped/torn & just ratty looking.

I'm well aware that the hood insulators actually stopped coming on the trucks from the factory at some point, as well as that the intercooler foil does little to nothing for charged air temp and is moreso there for sound deadening.

I recently ordered a decent supply of FatMat (cheaper version of Dynamat) to do some sound deadening on the inside of the truck. I'll likely end up with a fair amount left over so I was thinking of using some of it to wrap the intercooler pipes as well as the underside of the hood.

Any obvious downsides to doing so? For the intercooler pipes, would I be better served using header/exhaust wrap? Remember, my goal isn't anything to do with temps, but engine noise reduction.

Thanks in advance...

I don't think I'd put the Fatmat on the IC tubes... What temps is it rated for? Under the hood gets pretty hot...

I think after you FatMat the cab, it will be much quieter. Also, I've heard that installing a HPX line will quiet down the injectors.

The FRX from riffraff or a regulated return fuel system will quiet down some of the injector cackle too. As well as the in tank mods. I heard rumor that putting bed-liner on the valve covers will help too but i am not sure about that.

Just keep the key turned off, it will be quieter then. Plus it will save thousands this year on diesel fuel expenses!!!
