And that illustrates another aspect of the anti-surge housing. The inlet is HUGE. On the GT2871 I am looking at it is 4" dia. and could be a problem.

huge is awesome.
steph, can you make anti-surge holes for, say, a 2876 compressor housing? http://gallery.y8s.com/d/437-3/gt25_86ar_02.jpg |

^^Are you talking about surge due to not using a BOV on a WRX? If so, I have always planned to use a BOV regardless of whether I use the anti-surge housing or not. I am using one now.

no issues with a 2871 on a 1.6L, i'd assume the same on a 1.8L.
|
How much boost on the 1.6?

The 2871 surges (mildly) on a WRX equipped with a BOV. During spoolup, surge doesn't care whether or not you have a BOV anyway.

And before the whole a/c debate thing starts, no I am not ditching the a/c :fawk: |
You could always use a 3"-4" coupler to use 3" tubing which will allow for easier intake path routing. Y8s has a HUGE intake, I love the way it looks but a complex routing for a cold air box with 4" tubing would be tough.

so much for velocity...
|
If you mean from the elbow, not really. It is such a large cross-section there will probably not be much head loss through there.
|
I think he was talking about the inlet velocity of air. As you increase the diameter of the path the air travels, the velocity slows down as well. Vice-versa happens when you make the inlet smaller. Yay physics/fluid dynamics! However, the difference will be barely measureable so I wouldn't worry about it...

Exactly. Going from a 3" intake tube and a small transition to 4" just before shrinking down to your 2" inducer has got to do some interesting things.
a 4" 90° is all you need: http://gallery.y8s.com/d/17058-2/DSC02751.JPG |

well no actually I need to get down to 3" eventually for the CAI so I can incorporate both transitions into one.
I think the flow regime will be fine and will not amount to more than a minor loss by my calcs. I am more concerned about the clearance. EDIT: Sorry I was traveling on business and did not have full access where I could see the picture above. That helps, thanks. After looking at yours, and looking more at the BEGI S4 system picts, I think it would fit with the 4" inlet if I use a 90 deg bend. |
