What exactly does the double inlet do? And are they functional on all the turbos you see them on? Like the fake chinese turbos you see them on....

thats not a double inlet?

thats for the vband

I meant There.....

Re: What Exactly Does This do??
 

There was a silencer ring in the turbo before, which is not there now. That is all.

Re: What Exactly Does This do??
 

Does air get into the turbo there??

Re: What Exactly Does This do??
 

They are anti-surge ports. I dont feel like explaining it, but everyone else is wrong.

Re: What Exactly Does This do??
 

yeah they are anti surge ports or called a ported shroud. i think they work like this. you know when you head a car on the dyno spooling up it starts making that woosh------woosh-----woosh----woosh---woosh--woosh-crazy spool sound? i think it takes that away becuase that sound is the turbo going into the surge area of its compressor map, not good.

listen to this vid when they start doing a power pull, http://youtube.com/watch?v=VNxNHcCexGU&feature=related

Nice thats what I wanted to know....So Are does get sucked in thru there...

One the Holsets they call it the "Map width enhancement ring" It pushes the compressor maps surge line to the left giving it a bigger usable area. It does hurt peak numbers a little bit though. But for a small displacement motor running a big turbo it is a nice thing to have.

I think it works by letting the front of the compressor wheel kinda of recycle the incoming air instead of going into full surge.

The picture above of the "silencer ring" is just that. On the oem dodge holsets they added a cone shaped plate that is held in with a big clip to quiet the turbo down. No difference with it on or off as far as performance is concerned, but it sounds better with it off.\

The original poster was not circling the lack of a ring. He circled a part of the compressor housing which happen to be the anti-surge ports. So telling him not to worry about a part that you do not normally see is to tell him to be ignorant, you happen to play the part very well.

Re: What Exactly Does This do??
 

All I really wanted to know is if the ports do suck in air?? And if every turbo with this port is functional....

Re: What Exactly Does This do??
 

Yes douchwad air gets sucked in the compressor housing through there, the movement of the air around those ports disrupts it and helps prevent the compressor wheel from being battered with revolting gases and makes that cool "woooooooo noise".

---- off Faggot!!! Sorry for Posting a question. Next time dont ------- answer it...

Re: What Exactly Does This do??
 

This is basically what they do.

During optimal conditions a minimal amount of air will get sucked through the anti-surge ports and mainly through the compressor wheel minor(inducer) side. If the turbo starts to flow more air then the engine can take at a given RPM you will get a backup of air in the charge piping the same way that it happens when you close the TB while boosting. Instead of this air reverting through the compressor wheel slowing it down and creating huge jerk loads on the fins and shaft the air will "bypass" the wheel through the ports and get sucked back in.

It is rumored that some efficeincy is lost because of these ports elsewhere in the range of the compressor but i have never been able to find data or compressor maps showing any difference between a ported and non-ported housing on the same compressor setup.

Re: What Exactly Does This do??
 

It appears the original poster changed his pretty little picture at the beginning of the post. So we were talking about two separate things. Regardless, you can still go fist yourself 8)

Thanks alot Nismo....

Re: What Exactly Does This do??
 

But he edited his post before you posted...

Re: What Exactly Does This do??
 

Maybe he hit reply, then looked it up while the window was open to double check, and in that time it was edited.
