Whats the purple dohickey on the compressor housing?

I think those have something to do with decreasing restriction since there are no flat edges.Air horn or trumpet ? I read a big debate on those a while back and forgot everyword. lol.

its an air horn, they work!

I always see those on thumper turbos. Doesn't it also have something to do with anit surge limiting?

It prevents a vena contracta condition, which limits flow.



Need a longer explanation?

...Looks like a gaping *******...



LOL



If you left the turbo without a filter on the front of it you risk sucking in well...anything, right? Just for show, right?

Couldn't you use one with some screen in between that and the compressor housing? Where would you buy something like that? I be interested to know more about them. Is it just called an air horn?

where do they sell these?

turbonetics

I guess I need the catalog. Its not listed on the website.

yeah their site sucks

So is the catalog worth ordering then?

You could probally set up a screen inbetween the two peices. Are screens safe, and do they flow better then a good filter?

any other colors?

You can't DRIVE with that on though, can you? I mean...no filter = death, right???



Don't you need a stand-alone just to be able to not use an MAF? I can't see how people are able to just hook up a cone filter directly to the turbo.

no a screen will NOT flow beter than a proper filter or just leaving it open....



Dave, you need a catalog just ask. they give them away at most all events and probobly have 50 of them sitting around... i can mail it with the rest of your stuff on monday...

Yea, hook me up and toss one in the box.

Thanks

I have driven with no filters on the intake before I woud say that your ok as long as you dont go down any dirt roads.

that's for the strip or show only. you cant drive that aroud town all day unless yuo like riskin your engine and turbo being destroyed. at the strip you can get away with running the airhorn without filter and such for max power and boost. but on the street it just isn't worth the rebuild and new turbo your are gonna need after a while.

the part is actually called an inducer diffuser. There are also anit-surge bleed ype diffusers.

I'v been told 500 RPM faster spool with no filter, and when my filter fell off one time i deff felt more power. I was on a rode i drive allost everyday floored in 1'st i had never broken loose on this rode in 1'st ever till that day. When i looked under the hood my filter was missing.
