Well, I got info. on how to take out the ring... I took it for a "test drive" and WOW... Sounds like a dern jet... Just thought id get that off my back... Thnks

What you're hearing is the sound of inefficiency.

That is not a "silencer ring" - it reduces turbulence at the compressor inlet, allowing more air flow thru the compressor wheel, which increases compressor output = more Boost, to all you shade-tree guys.

If ya really wanna hear the turbo sing, put a mike on it and connect it to your stereo...................

P.J

Like to see this theory tested on a dyno. I agree that it is more than just a ring to silence, but doubt that it has a measureable effect. Some aftermarket turbo's don't even have a groove to accept a clip for a ring??

Those are 'general-purpose' turbos, can fit into anyone's intake\exhaust system scheme.

Not meaning they're deficient in any way - most 'built' intake systems consist of a paper cone-type filter clamped directly on the compressor inlet.

The more direct the intake path, and the straighter, the less inlet turbulence - but, any restriction - air filter, etc, - causes turbulence.

OEM systems generally consist of a heat-shielding filter-box and ducting to a reasonably cooler - and, preferably, higher pressure - source of intake air from the front of the truck, whether in a fender-duct or, like the newer fords, side of the grille.

The fender duct in the '94-'02 Dodge trucks has a large cool air inlet back at the passenger-side door, with a 90deg turn into the filter box, then something more than 90deg into the inlet of the compressor.

The 180deg inlet path causes turbulence at higher Boost levels - the greater the intake flow, the greater the effect.

And, I agree - some dyno runs with\without the ring would be informative, including runs with revised, straighter inlet path(s)

I think it has been done, just can't remember where I saw it - wasn't much interested in Diesels, prior to late last century.

BTW - the ring compares, primitively, with the straightening vanes - forgot what Dodge calls that plastic assembly - in the late EFI Diesel systems.

This discussion has been kicked around many times, I would be willing to bet that there is no difference in performance by taking the silencer ring out, its such a small factor when you think of how much air the engine is actualy sucking in. Some say it reduces their turbo bark too by removing it.

Ridiculous

i'm with DEEZLE98 this subject has been beat to death! ya'll just do a search and you'll find what you do or don't wanna know!

if this is true, how come you never see a silencer ring on a turbo in a semi or tractors? im just curious to know if there is a reason besides people who drive pickups like them to be a little quieter in the cab

Ridiculous

like i said earlier just do a search and you'll see what i'm saying, but i did read a thread on here that stated that the silencer ring was placed inside of the turbo as a request upon daimler-chrysler corp. and it was placed in there JUST to silence the turbo and that is it.

i'll search myself and see if i can't find it, but there is a WHOLE lot of info on this matter, just like FP guages, "ford owns cummins" etc etc.....

Ridiculous
